  • Patent number: 10114860
    Abstract: A case management system includes a case database storing case records in association with respective internal case identifiers. Operation includes automatically generating memorable case identifiers and providing them to users for use in identifying respective case records, the memorable case identifiers being generated by encoding the internal case identifiers with respective user identifiers as respective sequences of words (e.g., 3-word sequences) of a natural language of the users according to an encoding function. Case records are retrieved from the case database and provided to the users based on memorable case identifiers received from the users, by decoding received memorable case identifiers into respective internal case identifiers and accessing the case database using the respective internal case identifiers from the decoding.

  • Patent number: 10044752
    Abstract: A single system for detecting and blocking all cases of null-byte injection in all text data received for a network, before the text reaches potentially vulnerable services in the network. A set of directed graphs is received, each one of the directed graphs corresponding to a singly encoded null-byte that is encoded according to a corresponding character encoding method contained within a set of character encoding methods. The set of directed graphs is used to generate an output finite-state machine that models detection of at least one multiply encoded null-byte that is encoded according to at least one of the character encoding methods contained in the set of character encoding methods. The output finite-state machine is loaded into an attack detection and prevention system that receives input text, and that detects null-bytes, including multiply encoded null-bytes, within the input text.

  • Patent number: 10038709
    Abstract: A computerized network defense system includes a user interface component for displaying an interactive landscape to an agent, including a graphical representation of (1) network components and interconnections within a computer network, (2) activity within the computer network, and (3) threat information associated with the activity. The activity and threat information is presented in visual association with corresponding network components and interconnections. Agent interaction with the landscape includes (a) selectively highlighting specific network components or interconnections, specific activity, and specific threat information represented on the interactive landscape, (b) causing additional more detailed information about a highlighted item to be displayed in a display element separate from the multidimensional graphical representation (e.g., pop-up box), and (c) selecting and directing use of remediation tools for remediation actions to counteract threat-associated activity.

  • Patent number: 9961093
    Abstract: Techniques are disclosed for detecting malicious remote-administration tool (RAT) software by detecting reverse-connection communication activity. Communications are monitored over one or more persistent connections, such as TCP (Transmission Control Protocol) connections. Each monitored connection is between an initiator device and a follower device, and the initiator device is identified as the device that sent an initial packet to the follower device in order to open the connection. The disclosed techniques detect reverse-connection activity on the connection by detecting that communications over the connection are actually driven by the follower device, indicating that a malicious RAT is using the connection.

  • Patent number: 9781158
    Abstract: Improved techniques involve comparing paronymous addresses received in transaction data with trusted sets of paronymous data stored in a database by both a trusted client computer and a trusted server computer. Along these lines, the trusted client computer sends data packets to the trusted server computer that contain network addresses and a secure identifier. In response, the trusted server computer sends acknowledgment data packets containing encrypted network addresses and the secure identifier. Upon sending the acknowledgement data packets, the server computer communicates the network addresses to an aggregator. When the client computer receives the acknowledgement data packets, the client computer communicates the network addresses to the aggregator. Once the aggregator receives transaction data containing paronymous addresses, the aggregator compares the paronymous addresses to those communicated to it by the trusted server and client computers.

  • Patent number: 9690930
    Abstract: Sequences of discrete events, such as clicks on a website, are evaluated for periodic behavior, a period is calculated, and the sequence is scored to determine the confidence that the sequence really exhibits periodicity. The random variations on the timing of the discrete events due to transmission delays or other factors may be reduced or eliminated from the evaluation. An apparatus for performing the method of evaluation may include a computer programmed to carry out the method.

  • Patent number: 9021583
    Abstract: A method is performed in a network security system implemented in a computer or electronic device that is coupled to secured online resources for detecting unauthorized accesses of those secured online resources. The method includes monitoring a user activity session. It is determined whether the user activity session is indicative of a hidden session by an attacker, where the determination includes comparing the user activity session to an average user activity session.

  • Patent number: 8627479
    Abstract: A computer readable storage medium with instructions executable on a host computer. The instructions record a relationship between a partner site and the host computer, substitute a reference to the partner site with a partner site alias referencing the host computer, deliver the partner site alias to a client, replace the partner site alias for the reference to the partner site in response to receiving the partner site alias from the client and augment the address of the client with an address alias. The address alias is sent to the partner site. A partner action and the address alias are received from the partner site. The address is exchanged for the address alias. The partner action is delivered to the client utilizing the address. These operations are monitored to identify client activity that constitutes a security threat at the host computer or the partner site.

  • Patent number: 8332212
    Abstract: A method and system for improving the efficiency of real-time and non-real-time speech transcription by machine speech recognizers, human dictation typists, and human voicewriters using speech recognizers. In particular, the pacing with which recorded speech is presented to transcriptionists is automatically adjusted by monitoring the transcriptionists' output by comparing the output acoustically or phonetically to the presented recorded speech as well as monitoring the resulting transcription, and accordingly adjusting the pacing.

  • Publication number: 20120016633
    Abstract: A non-transitory computer readable storage medium includes executable instructions to observe the distribution of the frequency of a recurrent behavior to form a histogram. A rehistogram of the histogram is computed to model the distribution of the frequency of the frequency of the recurrent behavior. The rehistogram provides an individual frequency relative to the total frequency of the recurrent behavior. The individual frequency is compared to a predicted frequency to form a difference frequency. An anomaly event is identified when the difference frequency exceeds an anomaly threshold.
