  • Patent number: 10263998
    Abstract: A processing device in one embodiment comprises a processor coupled to a memory and is configured to obtain a plurality of security alerts in a computer network, to process the security alerts to extract a plurality of markers from each of the security alerts, to compute at least one relevance score relating a given one of the security alerts to another one of the security alerts based at least in part on distance measures computed between markers shared by the given security alert and the other security alert, and to adjust at least one operating characteristic of a network security system of the computer network based at least in part on the relevance score. The relevance score may be computed as a function of a number of markers shared by the given security alert and the other security alert.

  • Patent number: 9680812
    Abstract: A technique is directed to operating an authentication system. The technique involves receiving an enrollment request to enroll a user in a new authentication procedure in place of an earlier-established authentication procedure. The earlier-established authentication procedure is operative to authenticate the user at a first security level within a range of security levels. The new authentication procedure is operative to authenticate the user at a second security level within the range of security levels, the first security level being at least as high as the second security level within the range of security levels. The technique further involves, in response to the enrollment request, initiating the earlier-established authentication procedure to authenticate the user. The technique further involves, in response to completion of the earlier-established authentication procedure, performing an authentication enrollment operation associated with the new authentication procedure.

  • Patent number: 9356968
    Abstract: A technique manages user authentication via common authentication framework circuitry. The technique involves receiving, by the common authentication framework circuitry, authentication requests from client devices of users belonging to multiple enterprises, the authentication requests including user identifiers identifying the users belonging to the multiple enterprises. The technique further involves accessing, by the common authentication framework circuitry, entries of an authentication policy database to select authentication policies for the authentication requests. Selection of the authentication policies is based at least in part on the user identifiers of the authentication requests. The technique further involves invoking, by the common authentication framework circuitry, authentication services in accordance with the selected authentication policies to perform user authentication operations in response to the authentication requests from the client devices.
