Methods and systems for implementing DevID enrollment for hardware redundant Trust Platform Modules (TPMs), are described. A system can include hardware redundancy for management modules, and for TPMs that correspond to each management module. Accordingly, a product can have a dual-TPM configuration, where both modules are associated with the same product. Further, a process that particularly considers the presence of dual-TPMs for creating, issuing, and enrolling DevID certificates is described. The process issues and maintains DevID certificates for each TPM by synchronizing dual sessions that correspond to each TPM. Also, the process accounts for duplicate identification data, for example allowing the certificate authority (CA) to sign certificates for dual-TPMs linked to the same chassis number. The process can include performing validation checks, rendezvous points, and locks to ensure that DevID certificates are successfully issued for each of the dual-TPMs, respectively. |

Content delivery
A method of managing a network for delivering content to a client device, where content segments are delivered over multicast to a proxy. The received segments are stored at the proxy, before delivery of those segments is made from the proxy to the client device over unicast. Whilst the proxy receives further segments over multicast, it probes the network by making unicast requests for data (dummy data or additional content segments), and receiving those segments over unicast from the content server. The multicast rate reception rate and the unicast (probe) rate are measured and a maximum network throughput is calculated as the sum of these two rates. Subsequent segments are then delivered from the proxy to the client device at the calculated maximum network throughput rate, or at some rate dependent thereon. Thus, the client device will receive segments at a rate that is more indicative of the actual maximum network throughput, so can better use its adaptive bit rate algorithms to determine whether a switch to higher bit rate segments is appropriate. |

Some cyber threats/attacks, or incidents, are composed of many different flows occurring at a very high rate, which generates a flood of logs that may overwhelm computer, storage, network, and cyberanalysis resources, thereby compromising cyber defenses. The present disclosure describes incident logging, in which a single incident log efficiently incorporates the logs of the many flows that comprise the incident, thereby potentially reducing resource consumption while improving the informational/cyberanalytical value of the incident log for cyberanalysis when compared to the component flow logs. Incident logging vs. flow logging can be automatically and adaptively switched on or off depending on the combination of resource consumption and informational/cyberanalytical value. |
