Patent number: 10764393Abstract: The present disclosure relates to a network device that determines a persistent network identity for a networked device. Specifically, the network device receives a service request that includes an identifier for a second network device in a sub-network among a plurality of sub-networks. The identifier uniquely corresponds to the second network device during a limited period of time. At least one sub-networks are unreachable by the service request. The network device aggregates partial networked device profiles corresponding to the second network device received from other network devices in at least the at least one sub-networks to generate a networked device profile. Moreover, the network device searches at least one caches to obtain the networked device profile based on the identifier in the service request, and correlates the identifier to a persistent network identity corresponding to the second network device based on the networked device profile.Type: GrantFiled: April 21, 2016Date of Patent: September 1, 2020Assignee: Hewlett Packard Enterprise Development LPInventors: Marco Casassa Mont, Yolanta Beresna, Simon Ian Arnell, Nipun Balan Thekkummal

Patent number: 10325092Abstract: Examples relate to dynamically adjusting a model for a security operations center (“SOC”). As such, the examples disclosed herein enable constructing a customer storage model over a set of time periods for a customer based on a set of resources of the SOC, a storage distribution model received from the customer related to expected usage of the set of resources, and a threat landscape for the customer. The customer storage model may be revised for a second time period based on actual storage use of the customer during a first time period, and a projection of an amount of data to be consumed in the second time period based on the threat landscape. Allocation of the resources in the SOC may be revised for the second time period based on the revision to the customer storage model.Type: GrantFiled: March 11, 2015Date of Patent: June 18, 2019Assignee: HEWLETT PACKARD ENTERPRISE DEVELOPMENT LPInventors: Marco Casassa Mont, Simon Ian Arnell, Mihaela Gittler
