Abstract
A server includes a service processor hosted by a baseboard management controller (BMC) and independent of a CPU of the server. The service processor performs a set of monitoring tasks including performing a deep packet analysis on at least a subset of incoming packets. The deep packet analysis includes maintaining state information about the packets, examining the state information to identify an order in which the packets arrived, reassembling the packets into a new arrival sequence that is different from the order in which the packets arrived, matching the new arrival sequence to attack patterns stored in an attack pattern database, and upon the new arrival sequence matching an attack pattern, adding source Internet Protocol (IP) addresses associated with the packets to a blacklist.
