  • Patent number: 12615237
    Abstract: Aspects of the present disclosure involve systems, methods, for encoding a firewall ruleset into one or more bit arrays for fast determination of processing of a received communication packet by a firewall device associated with a network. Through this bitmap, a number of computation operations needed to determine a processing rule for a received packet is significantly reduced compared to the traditional approach of using a hash or a longest prefix match technique. Rather, determining a processing rule for a received packet may include determining a bit value within one or more arrays. In one implementation, a firewall rule may be encoded into a 64-bit array of bit values in which each bit of the array corresponds to a particular processing rule for a particular network address. The firewall rule may be encoded into a bitmap array of bit values by asserting a particular bit within the array.

  • Patent number: 12587519
    Abstract: Systems and methods for enforcing compliance-program conformity during authorization-token generation are presented. Applications may be registered with an identity and access management (IAM) system. The registration of the application may include whether the application is subject to one or more compliance program(s). When an authorization token is requested from the IAM system, the IAM system may (a) determine the set of authorization information needed in the token, and (b) determine whether the application is subject to a compliance program. The IAM system may then check an approval source of record to determine whether the user was legitimately approved for the required authorization prior to granting an authorization token. If there is a mismatch between the approval source of record and the authorization information associated with the user identity, then the mismatch may cause certain mitigation actions to be performed.

  • Patent number: 12579018
    Abstract: Novel tools and techniques are provided for implementing intelligent alert automation (“IAA”). In various embodiments, IAA receives alert/event feeds from several different alerting and ticketing systems via input Redis queues, and uses a triage system to determine whether to process the alert/event or disregard it. If so, IAA may create a flow instance, assign a unique instance ID, and place the flow instance in one of a plurality of jobs queues based on alert/event type and/or or source. An abattoir system retrieves a flow instance from one of the jobs queues (in order of the queue's priority), and processes the next node or step in the flow instance. The flow instance is placed back into the jobs queue for subsequent processing by the same or different abattoir system until no additional nodes or steps remain in the flow, at which point the flow instance is considered complete.
