  • Publication number: 20230281301
    Abstract: According to one embodiment, an Information Handling System (IHS) includes a memory to store a secure event log associated with one or more attributes of the IHS, and computer-executable code to obtain a system time from a system clock of the IHS, obtain a network time from a network time protocol (NTP) server, and compare the system time against the network time. When the obtained system time does not match the obtained network time, set a system clock attack chain vector in the secure event log and generate an Indicator of Attack (IoA) report based at least in part, on the system clock attack chain vector.

  • Patent number: 7596135
    Abstract: Methods and apparatus for routing mixed cast requests through a Clos-like network are disclosed. According to one aspect of the present invention, a method for processing a routing request within a network system includes computing costs associated with input links between a center stage and an input stage and computing costs associated with output links between the center stage and an output stage. The method also includes comparing the costs associated with the input links and the costs associated with the output links to identify a first input link, a first output link, and a second output link. The first output link is associated with a first center stage node and the second output link is associated with a second center stage node. The request is routed using the first input link, the first output link, and the second output link.
