Abstract: Techniques are presented for detecting and remediating security events. One method includes ingesting signals and telemetry from various tools like Software as a Service (SaaS), Endpoint Detection and Response (EDR), Mobile Device Management (MDM), and Secure Access Service Edge (SASE). Live session graphs are created for users, mapping all application token sessions. The system collects data from multiple sources to construct detailed graphs that represent user sessions, application usage, device employment, and third-party application tokens. This helps identify both legitimate and suspicious sessions, reducing false positives and enhancing effectiveness. Session graphs are analyzed to detect security threats, identify suspicious activities, and determine appropriate responses. Further, remediation tools are provided to address security events manually or automatically through established policies.

Abstract: Methods, systems, and computer programs are presented for stitching a meta session with an underlying trail fragmented across multiple distributed sessions. One method includes receiving telemetry signals from entities in a session environment that includes at least one identity of a user engaged with applications via respective meta sessions. An underlying trail for each meta session is determined, where the underlying trail is fragmented across two or more sessions with two or more entities. For a first meta session with a first application for the identity of the user, several operations are performed, including correlating a signal hierarchy based on the telemetry signals; constructing, based on the correlated signal hierarchy, a session hierarchy underlying the first meta session distributed across the one or more entities; determining a posture of the first meta session based on the constructed session hierarchy; and enforcing a security policy based on the determined posture.

Abstract: Methods and systems for managing a Multipath Transmission Control Protocol (MPTCP) in an electronic device during data transport between the electronic device (client device) and other electronic device (host device) are described. The method includes monitoring one or more factors associated with the MPTCP implemented in the client device. Further, based on the one or more factors that are monitored, the method includes determining whether to enable the MPTCP in the electronic device for a current data transport. Thereafter, the method includes determining a mode, among a plurality of modes provided for the MPTCP, to control a plurality of subflows of the MPTCP when the MPTCP is enabled for the current data transport. The method further includes dynamically switching the mode of the MPTCP during the current data transport based on the one or more factors being monitored during the current data transport.

Abstract: Disclosed herein is a logic circuit which responds to three signals to detect whether the number of signals taking one of logic-1 and logic-0 is odd or even, and includes five NAND gates. The first NAND gate is supplied with the first signal, the second signal and the third signal; the second NAND gate is supplied with the inverted first signal, the inverted second signal and the third signal; the third NAND gate is supplied with the first signal, the inverted second signal and the inverted third signal; and the fourth NAND gate is supplied with the inverted first signal, the second signal and the inverted third signal. The fifth NAND gate is supplied with outputs of first, second, third and fourth NAND gates and produces the output signal whose logic level is dependent on whether the number of the input signals taking one of logic-1 and logic-0 is odd or even.

Abstract: In a method of block coding, each character of the codeword may be thought of as a sum of characters of the message word, computed such that each message-word character that contributes to the sum is weighted by a respective weight coefficient. In the method described here, the weight coefficients are derived from a division polynomial of an elliptic curve.
