Abstract: The concepts and technologies disclosed herein are directed to a website verification service. A system can receive, from a web server that hosts a website, a query for a set of authentication credentials (“credentials”) to be used to verify that the website is trustworthy. The system can generate and provide the credentials to the web server. The web server can, in turn, provide the credentials to a web browser device for presentation to a user via a web browser application executing on the web browser device. The system also can provide the credentials to a verifier device. The verifier device can present the credentials to the user via a verifier application executing on the verifier device. The user can compare the credentials presented via the web browser application to the credentials presented via the verifier application executing on the verifier device to determine whether the website can be trusted.

The system also includes a gateway configured to perform operations that include receiving a second user input, deriving a second CAK based on the second user input, identifying the first CAK of the IED, establishing an adoption link with the IED based on a match between the first CAK and the second CAK, generating a third CAK, and distributing a copy of the third CAK to the IED via the adoption link to establish a MKA connectivity association with the IED.

Abstract: Techniques are provided herein for tracking activation events associated with a given serial number and using the data from the activation events to autonomously determine whether the serial number has been leaked. Numerous different characteristic parameters of activation events collected over a given time period for a serial number can be tracked and stored in a database. A plurality of different input variables can be generated based on the characteristic parameter data, which create the inputs that are used by a trained neural network to determine the leakage probability. If the leakage probability is determined to be above a certain threshold, an alert of some kind can be generated to indicate that the serial number has been leaked.

Abstract: A method for validating a Uniform Resource Locator (URL) includes generating electronic media content including the URL, generating a Certificate Signing Request (CSR) including the URL, sending the CSR to a certificate signing server, receiving a signed certificate corresponding to the CSR from the certificate signing server, and encoding the signed certificate as metadata in the electronic media content and/or encoding a serial number associated with the signed certificate as metadata in the electronic media content. A user can send the URL to another user through a chat message, an email, a word processing document or other business application, or a document which has a URL through a pen drive, email, or chat message. The certificate-based mechanism is used to validate the origin (sender) of the URL so that the recipients know that the URL can be accessed without having to separately analyze the security risks.

Embodiments of the present invention can then, in response to the generate real time risk score exceeding a threshold level of risk for the respective user interaction, initiate a secondary authentication protocol.

Abstract: A method of providing continuous user authentication for resource access control includes launching a continuous authentication service at a boot time of a first device, wherein the first device includes a processor, a memory, and one or more sensors configured to collect authentication information. Additionally, the method includes receiving authentication information comprising one or more of explicit authentication information or implicit authentication information, and receiving a request for access to a resource of the first device. Further, the method includes the operations of determining, by the continuous authentication service, a current value of a security state, the current value of the security state based in part on a time interval between a receipt time of the authentication information and a current time and controlling access to the resource based on the current value of the security state.

Abstract: A remote wipe message or notification may be sent from a server computer to one or more target client devices associated with a user. A managed container running on a target client device associated with the user and having a managed cache storing content managed by or through the server computer may, in response to the remote wipe message or notification, deleting the managed content or a portion thereof from its managed cache. The managed container may send back an acknowledgement or message to the server computer that it had completed the remote wipe. The remote wipe functionality can avoid having to deal with individual applications running on the client device and therefore can eliminate the complexity of having to deal with individual applications. Furthermore, the remote wipe can be done independently of the local operating system and without affecting non-managed information/applications on the client device.

Abstract: A computer method and system for determining patterns in network traffic packets having structured subfields for generating filter candidate regular expressions for DDoS attack mitigation. Stored packets are analyzed to extract a query name for each stored packet. Each query name is segregated into subfields. A Results-table is generated utilizing the segregated subfields of the query names. A Field-length table is generated that contains the length of the Field Values (Field-length) for each Field Name and an associated counter indicating how many instances the Field-length for a Field Name is present in the extracted query names. The Field-length table is analyzed to determine patterns of equal length in the “Results” table. Utilizing the Patterns table, unique combinations of the Field Values are generated as a filter candidate regular expression for DDoS attack mitigation purposes.

Abstract: Systems, methods, and computer media for securing software applications are provided herein. Through an enhanced authentication token, an application session request can be deceptively authenticated. When a malicious session request is detected, an enhanced authentication token can be generated that appears to successfully authenticate the session but contains information indicating that the session is malicious. The attacker believes that the session has been authenticated, but the information in the token indicating that the session is malicious causes an application clone session to be established instead of an actual application session. The clone session appears to be an actual application session but protects the valid user's account by including fake data instead of the user's actual data.

Abstract: A method for electronically signing contracts between at least a first and a second parties, the method including a first party accessing second party's website and fills in an on-line form with party personal data which is sent to a second party's server. The method of the inventions solves the problem of signing contracts between two parties, hence the object of the present invention is a computer implemented method that deals with the issue of protection against unauthorised use of data from within the employees of TTP companies and we present a solution in which a TTP company can certify the validity of a contract without having access to its content. In this way, the TTP minimizes the information it has access to and reduces the risks derived from such knowledge, like an eventual data leakage caused by some dishonest TTP employee.

Abstract: Examples are disclosed for detecting synthetic online entities that may be used for fraudulent purposes or other purposes. In some aspects, a computing system can generate a data structure that includes nodes and links between the nodes. The nodes can represent online entities and the links can represent geographic associations or transactional associations between pairs of online entities. These associations can be identified from electronic transactions involving the online entities. The computing system can determine, from the links between the nodes, that a degree of connectivity among a subset of the nodes exceeds a threshold connectivity. The degree of connectivity indicates electronic communications involving online entities represented by the subset of the nodes. The computing system can transmit, based on the degree of connectivity exceeding the threshold connectivity, an alert indicating a potential synthetic entity (e.g., potentially fraudulent activity) within the subset of the nodes.
