Abstract: A computerized method involves obfuscating one or more segments of data that is part of a flow prior to analysis of the flow for malware. Each of the one or more obfuscated data corresponds to one or more anonymized data. Thereafter, an identifier is generated for each of the one or more anonymized data, and each identifier is substituted for its corresponding anonymized data. The anonymized data and its corresponding identifiers are separately maintained from the stored flow.

Abstract: The present disclosure relates to methods and apparatus for flexible, security context management during AMF changes. One aspect of the disclosure is a mechanism for achieving backward security during AMF changes. Instead of passing the current NAS key to the target AMF, the source AMF derives a new NAS key, provides the new NAS key to the target AMF, and sends a key change indication to the UE, either directly or through some other network node. The UE can then derive the new NAS key from the old NAS key. In some embodiments, the AMF may provide a key generation parameter to the UE to use in deriving the new NAS key. In other embodiments, the target AMF may change one or more security algorithms.

Abstract: A verification server provides certificate verification services to users of third-party application sites. In some embodiments, a verifier component of a user's client device provides the verification server with a certificate of a third-party application site, and the verification server indicates whether the certificate is successfully verified. In response to successful verification, the verifier component of the user's client device takes an action such as permitting the user's credentials to be provided to the third-party application site. In some embodiments, verifier components of numerous client devices provide certificates to the verification server, based on which the verification server learns which certificates are valid for a given third-party application site.

Abstract: The disclosed technology teaches distributed routing and load balancing in a dynamic service chain: receiving and processing a packet, with added header including stream affinity code, at a first service instance and based on processing determining a second service, among available services, that should next handle the packet. The technology teaches accessing a flow table using the stream affinity code in the header to select a service instance performing the second service in the service chain, and routing the packet to the second service instance upon egress from the first service instance. When the flow table lacks an entry for the second service corresponding to the stream affinity code, the disclosed technology teaches accessing a consistent hash table of service instances performing the second service, selecting an available instance, and updating the flow table to specify the second service instance as providing the second service for packets sharing the header.

Abstract: Systems and methods for identifying a security risk include a security group analyzer that identifies a first set of users belonging to a security group such as a local administrators' group. A privileges analyzer identifies a second set of users having one or more privileges gained from user rights assignments that may pose a security risk. An autostart extensibility point (ASEP) access analyzer identifies a third set of users by identifying users having access to an ASEP entry or an image path identified by an ASEP entry. A security risk identifier identifies security risks by identifying users that are in the second or third set of users but are not in the first set of users. A security handler performs a responsive action in response to the identification of the security risk. A security graph builder uses the identified interrelationships to build a security graph that illustrates the security risks.
