The solution design provides a blue print to implement a distributed memory data repository based defense system across multiple nodes with dynamic fail-over capabilities. The defense system runs independently on a single node, exclusively leveraging memory for data storage and implementing a communication channel to interact with other nodes.

Abstract: Embodiments of this disclosure provide techniques for communicating in a wireless communication system. In particular, a user equipment (UE) may receiving a security command message from a base station comprising an indication of an integrity protection algorithm and an indication of an encryption algorithm. The first security command message may trigger a radio resource control (RRC) traffic signaling protection procedure between the UE and the base station. The UE transmits a security command complete message to the base station. The security command complete message may trigger a packet data unit (PDU) session establishment procedure to establish a PDU session between the UE and the base station.

Abstract: A ledger stores chain of custody information for files throughout an enterprise network. By identifying files with a homologous identifier such as a fuzzy hash that permits piecewise evaluation of similarity, the ledger can be used to track a chain of custody over a sequence of changes in content, ownership, and file properties. The ledger can be used, e.g., to evaluate trustworthiness of a file the first time it is encountered by an endpoint, or to apply enterprise policies based on trust.

Abstract: Example techniques detect incidents based on events from or at monitored computing devices. A control unit can detect events of various types within a time interval and aggregate the detected events into an incident. The control unit can detect patterns within the events based at least in part on predetermined criterion. In examples, the control unit can determine pattern scores for the patterns based on the probability of occurrence for the patterns and determine a composite score based on the pattern scores. The control unit can determine that an incident indicating malicious activity has been detected based in part determining that the composite score is above a predetermined threshold score. In some examples, the control unit can classify and rank the incidents. The control unit can determine if an incident indicates malicious activity including malware or targeted attack.

Abstract: An allowed client server, that is authorized to access a resource server over a given port, receives a client request, from a client computing system, to access the resource server. The allowed client server authenticates and authorizes the request, using an authentication and authorization mechanism, and selects a port with which to communicate with the client computing system. The identity of that port is provided to the client computing system, and a port forwarding mechanism forwards traffic between the client computing system and the resource server, through the client-facing port and to the given port on the resource server.

Abstract: An Internet resource provider (IRP) may authenticate a user and, upon a successful authentication, allow the user to perform one or more actions on webpages that are within an account of the user. The IPR may store the most recent actions of the user in a temporary access code (TAC) database. If the user has a problem, the user may select a TAC button on a webpage within the account of the user. The IPR may generate a TAC, store the TAC in association with the recent activities of the user in the TAC database and transmit the TAC to the user. The user may contact and provide the TAC to a customer support service center. The customer support service center may authenticate the user based solely on the TAC and determine the one or more recent actions of the user in the TAC database. The customer support service center may provide assistance to the user based at least partially on the one or more recent actions of the user.
