BACKGROUND1. Field of the Invention
The present invention relates to information security assessments and, more particularly, to information security assessments based on one or more of information technology infrastructure characteristics, components, configuration, connectivity, and/or architecture, information handling policies, procedures, training, and/or awareness, enterprise type, and/or user area of expertise.
2. Related Art
Corporate and government enterprises rely on a variety of types of information, such as customer information, vendor information, personnel information, and regulatory filing/compliance information. If any of this information is compromised, whether by accident or malicious intent, then the business of the enterprise suffers. Assessing and improving information security is thus a goal of an enterprise.
Information security has both technology based elements and non-technology based elements. Deficiencies in either may compromise information security.
Technology based elements of information security typically include information technology (“IT”) infrastructure characteristics, components (hardware and software), configuration of the components (e.g., version and patch history of an operating system, routers, and firewalls), connectivity of the components, and architecture. Information security can be compromised by weaknesses and/or vulnerabilities in IT components, configuration of the IT components, connectivity of the IT components, architecture of the entire IT infrastructure or portions thereof. These are referred to as technology based vulnerabilities and risks.
For example, many technology components, hardware and software, have known inherent vulnerabilities and/or risks. Vulnerabilities and/or risks may vary by manufacturer, version, installed patches, etc. Similarly, the way in which IT components are configured may create vulnerabilities and/or risks to the information handled by the IT infrastructure. For example, hardware switch settings or software settings may be associated with known vulnerabilities and/or risks to the information handled by the IT infrastructure. Similarly, the way in which IT components are interconnected may create vulnerabilities and/or risks to the information handled by the IT infrastructure.
Non-technology based information security elements can include information handling policies, procedures, training, and/or awareness. Information security handling policy generally refers to guidelines, instructions, rules, and/or regulations for handling information. Information security procedure generally refers to specific step-by-step instructions for implementing security handling policies. Information security policies and procedures tend to vary by enterprise type and by the type of information being handled.
Depending upon the context, information security policies may also refer to policies implemented within an IT infrastructure, such as firewall policies, for example. Vulnerability and risks associated with this category of information security, however, generally falls under the rubric of technology based vulnerabilities and risks, rather than non-technology based vulnerabilities and risks.
A fundamental goal of an information security policy is to communicate to everyone in an enterprise that information is a valuable asset to the enterprise and that everyone is responsible and accountable for protecting the information. A security policy is a visible representation of security considerations, requirements, priorities, assumptions, and responsibilities.
A security policy provides many benefits to an enterprise, including, without limitation:
demonstrates management commitment to protecting enterprise information;
provides cost benefit analyses of security measures to mange risk and protect enterprise assets;
supports an enterprise's mission and goals and acts as an enabler for the enterprise;
identifies what information must be protected;
establishes who is responsible for protecting information;
provides unambiguous expectations for employee conduct and responsibility;
provides consequences of misuse;
minimizes negative exposure to the enterprise by limiting liability, negative press, etc;
guides product selection;
ensures proper implementation of IT.
Security policies are developed by identifying information to be managed, determining the value of the information, determining the way the information is used, identifying who creates and uses the information, assessing risks to the information, and deriving requirements for protecting the information.
Information security can be compromised by deficiencies in IT infrastructure characteristics, components, configuration, connectivity, and/or architecture, and/or by deficiencies in information handling policies, procedures, training, and/or awareness.
In order to protect information, an information security assessment should be performed to identify any deficiencies in systems and/or processes. A proper information security assessment results in corrective measures and policy fixes that are appropriate for the types of information used by the enterprise, the way(s) in which the information is used, and the nature of the threats facing the information, and vulnerabilities associated with the systems and processes.
What is needed, therefore, is a system and method for assessing information security that takes into account technology based vulnerabilities and risks and non-technology based vulnerability and risks.
Information security vulnerabilities and risks vary by enterprise type. This is due, in part, to types of information handled by different types of enterprises, different types of threats faced by different types of enterprises, and/or different IT infrastructures. Thus, government enterprises, for example, may have different vulnerabilities and risks than commercial enterprises.
What is needed, therefore, is a system and method for assessing information security that takes into account an enterprise type, including consideration of any industry specific vulnerabilities and risks.
Within an enterprise, information needed to properly assess information security may not rest with a single individual or even within a single group of individuals. For example, IT information may be spread among multiple individuals or groups of individuals. The individuals or groups of individuals may be geographically diverse. For example, wide area network (WAN) knowledge might be with a WAN administrator, local area network (LAN) information might be with a LAN administrator. Other types of IT information might rest with one or more server administrators, IT supervisors, a CIO, etc.
Similarly, policies and procedures may vary within an enterprise depending upon the type of information being handled. For example, financial information, intellectual property information, human resource information, employee information, merger and acquisition information, regulatory information, and other types of information, may each have their own policy and procedure. Different individuals and/or groups of individuals may not be necessarily be aware of, or need to be aware of, policies and procedures outside of their respective areas of expertise.
What is needed, therefore, is a system and method for assessing information security that considers users' areas of expertise. Such a method and system should interview a plurality of users, based on each user's area(s) of expertise, to help insure that questions are answered accurately by qualified users, and to obtain an overall picture of information security within an enterprise.
An enterprise may define itself in terms of departments, subsidiaries, or other terms (generally, “domains”). Domains may be legally distinct domains or enterprise defined domains. domains may or may not be geographically based. Different domains within an enterprise may have similar and/or distinct information security issues to be addressed. For example, two or more domains within an enterprise may have substantially similar information security concerns, including technology based concerns and non-technology based concerns. On the other hand, two or more domains within an enterprise may have distinctly different information security concerns, including technology based concerns and non-technology based concerns.
What is needed, therefore, is a system and method for assessing information security that takes into account domains within an enterprise. Such a method and system should include a process for rolling-up information security information from various domains to perform an enterprise wide information security assessment.

Non-technology based questions can include, without limitation, questions related to information security handling policies, procedures, training, and/or awareness.
In an implementation of this embodiment, the present invention determines enterprise vulnerabilities and risks based on an integrated assessment of user responses to technology based questions and non-technology based questions. For example, one or more vulnerabilities and/or risks will depend upon user responses to both a technology based question and a non-technology based question.
However, the present invention is not limited to this embodiment. For example, one or more vulnerabilities and/or risks may depend only upon user responses to technology based questions. Similarly, one or more vulnerabilities and/or risks may depend only upon user responses to non-technology based questions.
In an embodiment, the present invention assesses information security based on an enterprise type, considering industry specific vulnerabilities and risks for the enterprise type.
In an embodiment, the present invention interviews users based on their areas of expertise. In this embodiment, the invention interviews users from multiple areas of expertise in order to obtain an overall information security assessment for the enterprise.
In an embodiment, the present invention assesses information security for domains within an enterprise. In an implementation of this embodiment, the invention includes a roll-up feature that assesses enterprise wide information security based on responses from users in the individual domains. In this mode, administrators across the enterprise will use the invention in each of the enterprise's constituent components. The results are then aggregated to identify security issues across the enterprise. This roll-up embodiment is useful as a building block of a larger assessment or policy development effort. In this embodiment, the invention can be implemented to develop an overall information security posture of an entire enterprise.
In an embodiment, the invention executes third party test/diagnostic/verification applications, such as CyberCop Scanner™, from Network Associates, McAfee or Symantec Antivirus, and ISS RealSecure™.
In an embodiment, the invention is implemented to assess security of information handled by a third party application, such as SAP and/or Oracle™, for example.

Definitions of various terms and phrases used herein are now provided. Detailed descriptions of the present invention follow the definitions.
A. DefinitionsFor this specification, the following terms shall have the indicated meaning(s).
Enterprise shall mean any type of entity that utilizes information, including, without limitation, government enterprises, non-government enterprises, commercial enterprises, non-commercial enterprises, for-profit enterprises, and non-profit enterprises. Generally, when a single information security assessment is performed, the scope of the information security assessment defines the enterprise. Multiple assessments are discussed below with respect to domains.
Domain shall mean a group within an enterprise. When a plurality of security assessments are performed and the results are rolled up into an overall information security assessment, the scope of the overall assessment defines the enterprise, and the scope of each of the individual assessments defines a domain within the enterprise. Domains can include, without limitation, geographic domains, function domains, content domains, and administrative domains. Domains can overlap one another. For example, individuals and/or IT components can fall within more than one domain.
“Information” shall mean any information of an enterprise, technical and/or non-technical, including, without limitation:
IT infrastructure information;
human resources information;
intellectual property information;
enterprise security information;
financial information;
accounting information;
customer information;
vendor information;
legal information;
employee information;
regulatory information;
compliance information; and
mergers and acquisition information.
“Information security” shall refer to security of any and/or all information of an enterprise, including that which is created, stored, moved within, and/or transmitted through IT assets of an enterprise (e.g., “electronic information”), and that which is not stored, moved within, and/or transmitted through IT assets of an enterprise.
“IT infrastructure” shall mean any and/or all hardware and/or software components related to storage, processing, and/or transferring of electronic information.
Vulnerability shall mean a weakness that could be exploited, intentionally or unintentionally. Weakness can include, without limitation, weaknesses in policies and/or procedures, bugs in operating system software, bugs in application software, and configuration mistakes. Vulnerability includes, without limitation, “threats” as described in various literature and/or U.S. Government regulations.
Threat, unless otherwise defined herein, shall mean any and all types of threats, and shall not be limited by any specific definition that may be used in the relevant art(s).
Risk, unless otherwise defined herein, shall mean any and all types of risks, and shall not be limited by any specific definition that may be used in the relevant art(s).
Deficiency shall mean technical and/or non-technical elements that reduce information security such as, for example, handling, set-up, and connectivity).
B. Example EnvironmentInformation security within an enterprise has technical and non-technical aspects. Technical aspects include information technology infrastructure (i.e., technical characteristics, components, connectivity, and architecture). Non-technical aspects include information handling policies, procedures, training and awareness. Information security can be compromised by deficiencies in either aspect. For example, information security can be compromised by deficiencies in IT infrastructure and/or by an individual's lack of proper information handling training and/or awareness.
Information security within enterprise 100 depends, in part, on the components that make up the IT infrastructure 102, their configuration, their connectivity with one another, and the overall architecture.
Information security within enterprise 100 also depends on information security handling policies, procedure, training and awareness. Typically, an enterprise will maintain some information within its IT infrastructure, some information outside of its IT infrastructure, and some information both within and outside of its IT infrastructure. Information maintained outside of an IT infrastructure may be maintained mentally by employees, and/or in a tangible media, such as in paper files, for example. Information security policies and procedures should take into account all types of information handled by an enterprise.
human resources information 204;
intellectual property information 206;
financial information 208;
mergers and acquisition information 210
accounting information 212;
customer information 214;
vendor information 216;
legal information 218;
employee information 220; and
regulatory information 222.
Information types 204-222 are for illustrative purposes only. Other types of information may also be used. Although information types 204-222 are illustrated as separate information types, two or more of information types 204-222 may overlap.
In the example of
The security of information types 204-222 depend upon the characteristics of the IT infrastructure 102 and upon the policies and procedures for handling the information types 204-222. The policies and procedures for handling the information types 204-222 can include, without limitation, policies and procedures for human handling and policies and procedures implemented within IT infrastructure 102.
The security of other information 224 depends upon policies and procedures for human handling, but does not depend on IT infrastructure information security.
The present invention is a method and system for assessing information security of an enterprise, such as enterprise 100. Based on the teachings herein, one skilled in the relevant art(s) will understand how to implement the present invention for other types of enterprises as well.
In an embodiment, the invention assesses information security based upon IT infrastructure characteristics and information handling policies, procedure, knowledge, training, and awareness.
In an embodiment, the invention assesses information security based upon an enterprise type, considering industry specific vulnerabilities and risks.
In an embodiment, the present invention interviews users based upon the users' area(s) of expertise.
In an embodiment, the present invention is implemented for various domains within an enterprise. A roll-up feature assesses enterprise wide information security based on information security assessments for the domains.
In an embodiment, the invention interviews one or more set-up administrators prior interviewing users to determine the type and/or structure of an enterprise and to selects questions appropriate for the enterprise.
The invention optionally includes one or more of a number of optional features described below.
II. METHODS FOR ASSESSING ENTERPRISE INFORMATION SECURITYThe present invention is now described in terms of a process. Example methods for implementing the process are provided for illustrative purposes only. Based on the teachings herein, one skilled in the relevant art(s) will understand that the present invention can be implemented with other methods as well, which are within the scope of the present invention.
Processing proceeds to step 304, assessing information security based on user(s) responses. Details and example implementations of assessing information security are provided below.
Processing then proceeds to step 306, reporting the information security assessment. Details and example implementations of reporting information security assessments are provided below.
A variety of optional start-up processes and/or initialization processes can be implemented as part of step 302. Example optional start-up processes and/or initialization processes are now presented.
A. Process Start-UpIn an embodiment, upon execution of the process, a user is prompted to provide identification information (e.g., user ID and password).
Upon successful login, the user is provided with one or more options, including, without limitation, starting a new assessment, initializing an assessment (described above), continuing with a previously started assessment, query an expert (described below), and/or executing third party testing/diagnostic applications.
In an embodiment, one or more user options are available to the user throughout the assessment process. For example, where the process is performed under control of a multi-tasking operating system, a user may be permitted to query an expert during an assessment interview, and/or executing third party testing/diagnostic applications.
In
In an embodiment, step 302 includes an optional initialization process that allows a set-up administrator to configure the process for enterprise particulars. For example, the optional initialization procedure can include querying a set-up administrator to tailor questions according to an enterprise type (described below), to tailor questions according to user areas of expertise (described below), to tailor questions for domains and roll-up (described below), and/or combinations thereof. These options are illustrated at a high level in steps 406-412 of
Referring back to
In an alternative embodiment of step 302, multiple users are interviewed. This may be the case where multiple users have information that would be useful to an information security assessment. In a multiple user embodiment, user interviews can be tailored according to users' areas of expertise. This is described below.
In an embodiment of step 302, users are interviewed with questions presented on a display under control of a computer. In this embodiment, users answer questions by entering them into the computer. In an embodiment, users provide answers by typing them on keyboard or other input device. In another embodiment, users may select an answer from a list of acceptable answers.
In an alternative embodiment, users are interviewed with computer controlled audible questions. In this embodiment, users may provide answers as described above or verbally.
In another alternative embodiment, users are interviewed verbally by a human.
In an embodiment, the process includes a plurality of question pools from which questions can be selected. In an embodiment, the process accommodates the addition of new question pools as they become available.
1. Interviewing Users with Technology and Non-Technology Questions
In an embodiment of step 302, interviewing questions are directed to technical issues, such as, without limitation, IT infrastructure characteristics, components, configuration, connectivity, and/or architecture.
In an embodiment of step 302, interviewing questions are directed to non-technical issues, such as, without limitation, information handling policies, procedures, training, and/or awareness, enterprise type, and/or user area of expertise.
In an embodiment of step 302, interviewing questions are directed to both technical issues and non-technical issues.
Two examples of technical and non-technical interviewing questions are provided at the end of this specification. Some of the example questions are presented with example working aids that provide explanations and/or definitions to assist a user in answering questions. These examples are provided for illustrative purposes only. Other questions can be posed to uses to identify deficiencies, vulnerabilities and risks.
2. Interviewing Users Based on Type of EnterpriseInformation security issues can vary according to the type of enterprise. For example, and without limitation, issues can include the type(s) of information handled by the enterprise, the importance of the information, the nature and extent of information security policies associated with the information, the types of IT infrastructure utilized by the enterprise, the layout or organization of the enterprise, and the nature of potential threats to the enterprise and its information.
Government enterprises, for example, typically have information security concerns different from and/or in addition to concerns of non-government enterprises. Information security concerns can vary among different types of government enterprises. As a result, different government enterprises may be subject to different compliance criteria. Certain government enterprises may have special security concerns because of their location or the nature of the work. For these reasons, the U.S. Government promulgates compliance criteria for different types of government enterprises. For example, current U.S. Government compliance criteria include, without limitation, Department of Defense Information Technology Security Certification Accreditation and Process (“DITSCAP”) and National Security Agency Information Security Assessment Methodology (“NSA IAM”).
Thus, in an embodiment of the invention, the process interviews users based on an enterprise type. In an implementation, the process selects questions from one or more pools of questions, depending upon an enterprise type. The one or more pools of questions include questions directed to industry specific vulnerabilities and/or risks.
Processing then proceeds to step 704, select enterprise relevant questions. Enterprise relevant questions can be selected in any of a variety of ways. In an embodiment, questions are stored in a database with an indication as to the type of enterprise to which they pertain. In some cases, a question will pertain to more than one type of enterprise. In an alternative embodiment, separate databases of questions are maintained for different types of enterprises.
Processing then proceeds to step 706, interview user(s) with the selected enterprise relevant questions.
From step 802, if the enterprise is a non-government enterprise, processing proceeds to step 804, select non-government relevant questions, followed by step 806, interview user(s) with the selected non-government relevant questions. If the enterprise is a government enterprise, processing proceeds from step 802 to step 808, select government relevant questions, followed by step 810, interview user(s) with the selected government relevant questions.
The examples herein are provided for illustrated purposes only. The invention is not limited to the examples herein. Based on the teachings herein, one skilled in the relevant art(s) will understand that the present invention can be implemented to interview users with enterprise specific questions for other types enterprises and/or compliance criteria as well.
3. Interviewing Users Based on Areas of ExpertiseIn an embodiment, users are interviewed according to their respective areas of expertise, as illustrated in
In an embodiment, questions are simply presented in groupings associated with areas of expertise, with no attempt to associate groupings with particular users. In an alternative embodiment, a set-up administrator is permitted to assign specific users and/or groups of users to one or more groups of questions.
In the example of
In an embodiment, the interviews include both IT infrastructure questions and policy questions.
Users may also be interviewed based on other information areas of expertise, such as the areas of information illustrated in
The example areas of expertise described herein are provided as illustration only. The present invention can be used to interview users based on other areas of expertise as well.
In an embodiment, a user's area of expertise is determined in advance during an optional initialization process, described above. Optionally, a user verification process—i.e., user identification and/or password—is utilized to insure that only predetermined users are interviewed.
Alternatively, or in combination with the above, questions are posed to a user at the time of interviewing to determine and/or verify the user's expertise.
4. Interviewing Users Based on Enterprise Type and Area of ExpertiseIn an embodiment, the process interviews multiple users based on the type of enterprise and the users' areas of expertise.
5. Working AidsIn an embodiment, working aids are provided to users. Working aids can be provided in a number of contexts and for a number of purposes. Working aids can include, without limitation, advice on information security considerations of installing or configuring components, explanations of why certain policy issues are important and possible consequences of not addressing them, definitions, and general reference material, including hot links.
Working aids are provided during the interviewing process of step 302 to assist in answering questions, for example. Working aids can also be provided with reports in step 306 to assist readers in understanding the reports. Working aids can also include working aids to assist users in developing solutions. For example, by suggesting one or more possible solutions and providing additional information to assist the user in deciding which solution is appropriate for the enterprise.
Working aids are provided in any of a variety of formats. In an embodiment, when a user is interviewed via a display terminal, availability of a working aid is indicated to the user with a special font, highlighting, or any other suitable display formatting technique. In this embodiment, the user can “click” or otherwise indicate that the available working aid is desired. The process will then provide the working aid.
Alternatively, working aids are presented automatically whenever appropriate.
6. Dynamic Interviewing—Question DependenciesIn an embodiment, the interviewing process is dynamic in that questions posed to a user can depend upon one or more prior answers from the user and/or from another user. This allows the process to ask additional information in areas where it might lead to a more thorough information security assessment. For example, if a user has additional information that could be useful, it would be prudent for the process to continue interviewing the user until the user's knowledge is exhausted.
Question dependencies can be utilized for example, when an answer to a question, or to a group of questions indicates a vulnerability or a potential vulnerability. Further questions and user responses may clarify the potential vulnerability or eliminate the concern.
Question dependencies also allow the process to cut short a line of questions that may not be relevant to the situation or to the user. For example, if a user indicates that he/she has no knowledge of a particular line of questioning, it would be pointless to ask additional details.
Question dependencies can be implemented, for example, as a nested loop of questions, whereby, when the nested loop of questioning ends, interviewing continues from where the nested loop began.
Question dependencies can also be implemented as a jump to another line of questioning, where interviewing may or may not return to the prior line of questioning.
D. Assessing User ResponsesReferring back to
Questions posed to users during step 302 are designed to elicit information from users necessary to determine which, if any, of the vulnerabilities and/or other considerations apply to an enterprise. The questions posed to users are preferably developed by persons having knowledge of the vulnerabilities and/or other issues.
Step 304 outputs deficiency statements based on the analysis of user responses, vulnerabilities and/or other considerations. Deficiency statements can be directed to technical and/or non-technical issues. Deficiency statements can include, without limitation, lists of identified vulnerabilities, deficiencies, critical deficiencies, and risks. Example embodiments of this process are described below. Deficiency statements can also include suggested corrective actions. Other example types of deficiency statements are found throughout this specification.
1. Logic Based AssessmentIn an embodiment, step 304 is performed by outputting information security deficiency statements that are associated with answers to one or more questions. This embodiment is referred to as logic based assessment.
For example, in some situations, the answer to a single question may indicate a deficiency (e.g., a vulnerability or risk, a lack of a relevant information security policies, lack of knowledge of a relevant information security policies, failure to follow an established information security policies, etc.). In other cases, however, a deficiency may depend upon answers to a series or group of related or unrelated questions. In other situations, a deficiency may be indicated by similar or conflicting answers to the same question or group of questions by multiple users.
Example systems for implementing logic based assessments are described below.
Information security deficiency statements can take many forms and can be directed to technology based deficiencies (e.g., deficiencies in IT infrastructure characteristics, components, configuration, connectivity, and/or architecture) and/or to non-technology based deficiencies (e.g., policies, procedure, training and/or awareness).
In an embodiment, step 304 includes prioritizing deficiencies.
In an embodiment, step 304 includes identifying critical deficiencies.
In an embodiment, step 304 includes identifying deficiencies in a local computing environment that require immediate attention, with or without recommended actions.
In an embodiment, step 304 includes identifying deficiencies in a local computing environment that require further analysis.
In an embodiment, step 304 includes generating a policy statement.
In an embodiment, step 304 includes generating a new policy statement. In an embodiment, step 304 includes generating a revised policy statement.
In an embodiment, step 304 includes generating a combination of two or more of the above example embodiments.
2. Expert Knowledge Based AssessmentsIn a embodiment, step 304 is performed with an expert (knowledge based) system in which knowledge from human subject-matter experts is encoded into a software program in such a way that the coded logic of the software program provides a searchable repository of this subject-matter knowledge. The expert system is encoded in such a way as to accept input and make inferences based on the implications of that input that a human subject-matter expert would normally be expected to make but which were not specifically encoded in the expert system.
3. Artificial Intelligence Based AssessmentsIn an embodiment, step 304 is performed with artificial intelligence (AI), such that input data is subjected to analysis by AI, and the problem solving methods and/or analysis and/or other tasks for which the AI is designed is modified by the AI itself as a result of the output of previous processing cycles.
4. Comparisons with Prior Assessments
In an embodiment, the present invention performs comparisons with prior information security assessments.
In an embodiment, comparisons with prior information security assessments are performed using current reports and prior reports.
In another embodiment, comparisons with prior information security assessments are performed using current analysis results and prior analysis results.
In another embodiment, comparisons with prior information security assessments are performed using current raw data and prior raw data.
In an embodiment, users can select among two or more of the above options when comparing information security assessments.
E. Reporting Information Security AssessmentIn an embodiment, step 306 generates and stores one or more pre-formatted reports. Reports can include, without limitation, critical deficiencies requiring immediate attention, deficiencies requiring further analysis, and/or enterprise-wide critical deficiencies.
Report information can include, without limitation, one or more of the following types of information:
scope of report (e.g., computing environment that was subject to the assessment, e.g, domain, organizational component);
date of assessment;
names of servers;
names of LANs;
version of process/software/took kit used for interviews/assessment;
version of tool kit modules and plug-ins used;
versions of third party software tools executed (active or passive);
user queries;
versions of question pools (including application specific question pools);
versions of vulnerability and risk pools used;
version of policy module used.
The various modules referred to above are described below in the description of a system for assessing information security.
In an embodiment, information is inserted into one or more standardized reports templates. Standardized report templates can include, without limitation:
risk assessment of local computing environment;
deficiencies in local environment requiring immediate attention;
deficiencies in local environment that require further analysis;
deficiencies that must be escalated for enterprise-wide analysis and resolution;
information security policy for local computing environment;
measure of enterprise conformance to the information security policy;
measure of overall security posture of the enterprise;
measure of the effectiveness of enterprise-wide security training and awareness programs; and
list of most serious information security problems facing the enterprise.
In an embodiment, upon a user command, a pre-formatted report is output. Alternatively, a user can be permitted to generate a report to include one or more user-selected report templates.
In an embodiment, a user determines where a report will be output (e.g., to a display, a printer, or to an I/O device for forwarding to another device).
F. Multiple Domain and Roll-Up FeaturesIn an embodiment, the present invention can be configured to assess information security for one or more domains within an enterprise, and to assess information security across the entire enterprise based on the security assessments from the totality of individual domains.
In an embodiment, a separate instance of the process 300 is implemented for each domain, and the results are analyzed to assess information security for the enterprise. See
In an embodiment, reports from individual domains are used to assess enterprise-wide information security.
In another embodiment, analysis results from individual domains are used to assess enterprise-wide information security.
In another embodiment, raw data (i.e., user(s) responses from individual domains) is used to assess enterprise-wide information security.
In an embodiment, users may select among two or more of the above options when assessing enterprise-wide information security.
G. Querying an ExpertThe present invention optionally includes a “query an expert” feature that allows users to query a repository of information related to information security, IT infrastructure, or any other type of information embodied within a repository.
In an embodiment, upon start-up, the user is prompted to select between performing an information security assessment and the optional query an expert feature. Alternatively, the optional query an expert feature is available at any time to the user. This can be implemented, for example, when the process of interviewing a user and the optional initialization process are performed under a multi-tasking operating system.
The process is preferably designed to permit updating of the repository of information.
H. Execution of Third Party Testing/Diagnostic ProgramsIn an embodiment, the present invention permits a user to execute a third party testing and/or diagnostic program, such as, for example, a program that actively probes an IT infrastructure or component(s) thereof, or one that passively monitors network activity.
In an embodiment, the process analyzes results of the third party program in conjunction with responses from users. For example, a vulnerability may depend upon a user response and test results. Alternatively, the process analyzes results of the third party program independent of responses from users. Alternatively, the present invention does not analyze results of third party testing/diagnostic program.
In an embodiment, test results are used to select one or more questions for interviewing users in step 302.
I. Assessments Directed to Third Party Application ProgramsIn an embodiment, the present invention interviews users with questions developed for one or more particular third party application programs. This is useful where a significant part of an enterprise's information is maintained under or as a part of a particular third party application program. For this embodiment, questions are designed to address IT infrastructure and/or policy issues associated with the third party application(s).
In an embodiment, this optional feature is selected and/or initialized during the optional initialization process.
In an embodiment, the invention is implemented to assess security of information handled by a third party application, such as SAP and/or Oracle™, for example. This can include provision of application specific information, such as questions, vulnerabilities, instructions and/or code. Application specific information can be stored in one or more databases and/or other repositories of an information security toolkit.
In an embodiment, the invention includes an application specific tailoring tool that allows users to generate and/or modify application specific information for the databases and/or other information repositories of an information security tool kit. In operation, the tool queries one or more users having knowledge of a third party application and knowledge of problem-solving methodologies employed by the enterprise for conducting information security assessments and evaluations.
For example, the tool may present a graphical depiction of sequential problem-solving steps to the user(s) and prompt the user(s) to rearrange the sequential problem-solving steps to correspond to the method that the enterprise uses to conduct information security assessments and evaluations.
In addition to capturing the method(s) by which the user conducts an assessment, the tool captures application-specific data. For example, and without limitation, the tool can capture one or more of the following types of application specific data:
questions to ask about the particular application;
vulnerabilities associated with the particular application;
material added to the “query an expert” function that would permit that function to be more appropriately used for the particular application; and
report templates for the particular application.
Information collected from the user is then stored and used to generate application specific information to implement the enterprise's methodology in a computer system. The generated application specific information may include, without limitation, a software interface to the application-specific databases and other data repositories.
Systems and methods for collecting problem solving information are commercially available. Based on the description herein, one skilled in the relevant art(s) will understand how to implement this aspect of the invention.
III. EXAMPLE SYSTEMS FOR ASSESSING INFORMATION SECURITYThe present invention can be implemented manually, and/or in software, hardware, firmware, manually, and/or combinations thereof. Systems for implementing the present invention are now described with the assistance of functional block diagrams. Based on the descriptions and functional block diagrams herein, one skilled in the relevant art(s) will be able to implement the invention manually, and/or in software, hardware, firmware, and/or combinations thereof.
In an embodiment, the invention is implemented in software as an interactive set of tools referred to generally herein as a security tool kit (“STK”), which operates from a CD-ROM or downloadable software on a user's desk top or lap top computer. The STK poses questions to a user about technical characteristics of a local computing environment and the procedures used to create, store, and transmit computerized information within the user's computers and between the user's computes and other computers. From the responses of the user, the STK identifies deficiencies in the capability of the local computing environment to protect information from unauthorized disclosure, and it will suggest corrective actions that can be applied to correct these deficiencies. The STK evaluates existing information security policies and procedures, and it will guide the user through the process of developing information security policies for the local computing environment.
The invention can be implemented for government enterprises, commercial enterprises, and for both government enterprises and commercial enterprises.
A. Example Security Tool KitDatabases 1308 also include vulnerabilities 1406, dependencies 1408, and risks 1410. Vulnerabilities 1406 is a repository of information security vulnerabilities. Dependencies 1408 is a repository of relationships among questions and answers. In other words, dependencies 1408 can include a function that map answers to results. Risks 1410 is a repository of information security risks, which can include generic risks and/or industry specific risks.
Databases 1308 also include optional working aids 1412, policy components 1414, and recommendation 1422. Policy components 1414 preferably include information security policies with numbered sections. Recommendations 1422 preferably include policy sections specific to identified deficiencies.
Databases 1308 also includes store responses 1416, store analyzed results 1418, and store reports 1420. Store responses 1416 include user answers. Store analyzed results 1418 can include the results of the inference engine 1304 and/or possible answers to questions associated with the questions. Store reports 1420 are generated by the report generator 1306.
In an embodiment, store responses 1416, store analyzed results 1418, and store reports 1420, include results from one or more prior information security assessments. In such an embodiment, analysis module 1304 includes a second inference engine for comparing assessments, and report generator 1306 includes a report generator for generating reports for assessment comparisons.
1. Optional Initialization ModuleThe optional initialization module 1310 can be implemented to perform a variety of functions and/or processes. For example, in an embodiment, the optional initialization module 1310 performs a Super User Function, which includes the following sub-functions:
specify if this is a new assessment;
authenticate “super user” with privilege to assign user names and privileges;
determine which users have privileges to enter data in specified STK modules (described below) for the current assessment; and
assign user names and access privileges to individuals.
In an embodiment, the optional initialization module 1310 performs a enterprise type identification process, which includes obtaining a company name and industry type.
In an embodiment, the optional initialization module 1310 allows users to start a new assessment, resume a previously begun assessment, or compare a previously completed assessment.
In the example embodiment described, the optional initialization module 1310 receives interactive user input and outputs an industry type and company identification information.
2. Interview ModuleThe interview module 1302 presents questions to users. In an embodiment, the interview module 1302 receives an industry type, selects industry specific questions, and presents the industry appropriate questions to users.
The interview module 1302 compares user answers to the database of possible responses 1404 and prompts the user to re-answer if an answer is not permissible. In an embodiment, the interview module 1302 checks answers for dependencies to other questions.
3. Inference EngineThe inference engine 1304 identifies information security deficiencies based at least on user responses (store responses 1420 in
third party vulnerabilities 2108;
third party testing/diagnostic application test results; and
user queries to a knowledge database (e.g, query an expert module 1902 in
In an embodiment, the inference engine 1304 first identifies vulnerabilities based on user responses to certain questions. The inference engine 1304 then analyzes the vulnerabilities, in light of any of a variety of relevant factors, which can include, without limitation, one or more of the user responses that were used to identify the vulnerabilities. Based on the analysis of any identified vulnerabilities, the inference engine 1304 identifies security deficiencies.
Information security deficiencies can include IT infrastructure deficiencies and policy deficiencies. Policy deficiencies can be in the form of information security policy sections or statements.
In an embodiment, inference engine 1304 determines risks. Risks can be based on one or more of, interview questions, associated user responses, industry type, vulnerabilities, and/or asset value. In an embodiment, the inference engine 1304 receives a list of questions, associated user answers, and an industry type, and outputs a rank ordered list of critical information security risks, policy sections associated with specified vulnerabilities, and policy sections associated with specified risks.
The inference engine 1304 can be implemented to perform one or more of the following tasks:
interprets results of active and/or passive third party testing/diagnostic software;
correlate answers with vulnerabilities;
identify deficiencies;
rank deficiencies in order of criticality; and
determine applicable sections of information security policy.
In an embodiment, inference engine 1304 is a logic based inference engine. In an example implementation, the logic is embodied in software, such as software compiled from C++, for example. Alternatively, the logic is a specification language, or interpreted language.
In an embodiment, inference engine 1304 is an expert system (or knowledge based system) in which knowledge from human subject-matter experts is encoded into a software program in such a way that the coded logic of the software program provides a searchable repository of this subject-matter knowledge. The expert system is encoded in such a way as to accept input and make inferences based on the implications of that input that a human subject-matter expert would normally be expected to make but which were not specifically encoded in the expert system.
In an embodiment, inference engine 1304 is an artificial intelligence (AI) system, such that input data is subjected to analysis by the AI-based inference engine and the problem solving methods or analysis or other tasks for which the AI system is designed is modified by the AI system itself as a result of the output of previous processing cycles.
In an embodiment, the inference engine 1304 permits users to review results of previously completed assessments, perform “what if” scenarios by varying the previously entered answers and inputs, and observe the resulting outputs. This can be useful, for example, in deciding how to change a computing environment.
In an embodiment, the inference engine 1304 permits users to compare results of a previous assessment with results of a current assessment.
Accordingly, the inference engine 1304 can be implemented to perform, or allow a user to select, one or more of the following functions:
choose a previously completed assessment to analyze;
choose a segment (e.g., portion or domain) of a selected a assessment to analyze (user may choose to select one or more such segments for comparison and analysis);
compare a selected assessment/segment(s) with a current assessment to identify differences;
permit user to vary or change answers to questions of a selected previously completed assessment/segment and observe the differences in the outputs and reports;
display results of comparison/analysis to user on a display; and
save results of comparison/analysis to pass to report generator.
4. Report GeneratorThe report generator 1306 can be implemented to perform one or more of the following features:
determine applicable report type;
format report for viewing;
format report for printing;
format report for saving in STK database 1308.
Typically, the report generator 1306 receives questions posed to users and associated user answers, a list of working aids accessed during an interview, and analyzed results of user interviews.
Example processes that are typically performed by the report generator 1306 are now described. Unless otherwise specified, these processes are optional and combinable.
In a determine a report type function, the report generator 1306 correlates questions and answers with one or more appropriate types of reports, and selects a report template from a database of templates. Report types can include, without limitation, the following:
risk assessment of local computing environment;
deficiencies in local environment that require immediate attention;
deficiencies in local environment that require further analysis;
deficiencies that must be escalated for enterprise-wide analysis and resolution;
information security policy for local computing environment;
measure of enterprise conformance to the information security policy;
measure of overall security posture of the enterprise;
measure of the effectiveness of enterprise-wide security training and awareness programs; and
list of most serious information security problems facing the enterprise.
The report generator 1306 inserts appropriate information into reports, such as enterprise identification information. The report generator 1306 also formats and inserts questions posed to users and user responses into the report.
Where optional working aids are utilized, the report generator 1306 inserts any working aid material that was accessed during an interview into the report. More specifically, the report generator 1306 selects appropriate templates for a working aids section of the report, and inserts selected working aids material into the report.
Where implemented, the report generator 1306 inserts results of any queries to the query and expert module 1902 (
Where implemented, the report generator 1306 inserts results of any executions of third party software into the appropriate report.
Where appropriate, the report generator 1306 inserts any analyses of prior assessments into the report. More specifically, the report generator 1306 selects a template for an appropriate report format and inserts prior assessment results into the report.
The report generator 1306 prints reports upon appropriate request and saves reports in a report database for future reference.
5. Graphical User InterfaceIn an embodiment, the STK 1300 includes a graphical user interface (GUI) with a pull-down menu structure. In an example implementation, the pull-down menu includes the following tool bars. The example below includes options for multiple domains, referred to in this example as segments. The example below is for illustrative purposes only. Other tool bars, tool bar features, and GUIs are within the scope of the present invention.
In an embodiment, the present invention includes a roll-up module for assessing information security for an enterprise based on multiple domains.
In
In an embodiment, the enterprise-wide inference engine 1702 combines user responses from multiple domains, looks for relationships among the responses, identifies deficiencies across the enterprise, and presents an aggregate description of the security posture of the enterprise.
In an alternative embodiment, the enterprise-wide inference engine 1702 combines analysis results from the multiple domains, identifies deficiencies across the enterprise, and presents an aggregate description of the security posture of the enterprise.
In an alternative embodiment, the enterprise-wide inference engine 1702 combines individual reports from multiple domains and presents an aggregate description of the security posture of the enterprise.
C. Query an Expert ModuleTwo example implementations of the optional query an expert module 1902 are presented below. These example implementations are provided for illustrative purposes only. Based on the teachings herein, one skilled in the relevant art(s) will understand that other implementations are also possible, which are within the scope of the present invention.
In a structured query implementation, the optional query an expert module 1902 permits users to ask structured queries. Upon receipt of a query, the query an expert module 1902 determines a relevant area of information security knowledge and presents a list of related information security knowledge to the user. The user can then select a specific item within the displayed area of information security knowledge.
In a natural language implementation, the optional query an expert module 1902 permits users to ask unstructured questions. Upon receipt of a query, the query an expert module 1902 determines a relevant area of information security knowledge and presents a list of related information security knowledge to the user. The user can then select a specific item within the displayed area of information security knowledge.
In an embodiment, the query an expert module 1902 correlates users' answers with related sections of the optional working aids database 1412. The query an expert module 1902 then presents retrieved working aids material to the user. This is useful, for example, to indicate to the user why a topic of the interview is important.
D. Third Party Testing/Diagnostic ModulesModule 2000 includes any necessary interfacing features to allow the STK 1300 to execute one or more selected third party testing/diagnostic programs. Optionally, the module 2000 also includes necessary interfacing features to all the STK 1300 to receive results from the selected third party testing/diagnostic programs, so that the STK 1300 can analyze the results in combination with user responses.
When implemented, module 2000 presents a list of available third party software applications to the user and receives a user selection. The module 2000 then executes the selected application, presents the results to the user, and makes the results available to the inference engine 1304 and/or the report generator 1306.
In an embodiment, based on answers obtained during the interview process, module 2000 determines which portion(s) of the third party application results to analyze. The module 2000 also determines the level of detail of the results of the third party application to analyze. The module 2000 extracts relevant information from the results of the third party application and presents the results of the analysis to the user. The module 2000 also preferably saves the results in the database 1308.
E. Third Party Application ModulesIn the example illustrated in
User interview module 1302, inference engine 1304, and report generator 1306, operate as previously described, with additional interviewing, assessing, and reporting functions provided by the optional third party application database 2102.

These signals 2226 are provided to communications interface 2224 via a signal path 2228. Signal path 2228 carries signals 2226 and can be implemented using wire or cable, fiber optics, a phone line, a cellular phone link, an RF link and other communications channels.
In this document, the terms “computer program medium” and “computer usable medium” are used to generally refer to media such as removable storage device 2212, a hard disk installed in hard disk drive 2210, and signals 2226. These computer program products are means for providing software to computer system 2200.
Computer programs (also called computer control logic) are stored in main memory and/or secondary memory 2208. Computer programs can also be received via communications interface 2224. Such computer programs, when executed, enable the computer system 2200 to perform the features of the present invention as discussed herein. In particular, the computer programs, when executed, enable the processor 2204 to perform the features of the present invention. Accordingly, such computer programs represent controllers of the computer system 2200.
In an embodiment where the invention is implemented using software, the software can be stored in a computer program product and loaded into computer system 2200 using removable storage drive 2212, hard drive 2210 or communications interface 2224. The control logic (software), when executed by the processor 2204, causes the processor 2204 to perform the functions of the invention as described herein.
In another embodiment, the invention is implemented primarily in hardware using, for example, hardware components such as application specific integrated circuits (ASICs). Implementation of the hardware state machine so as to perform the functions described herein will be apparent to persons skilled in the relevant art(s).
In yet another embodiment, the invention is implemented using a combination of both hardware and software.
