Systems and Methods for Automatically Adjusting a Time-Based Anti-Replay Window Size

Abstract: in one embodiment, a method includes receiving, by a network node, a packet associated with a session. the method also includes performing, by the network node, a sequence-based anti-replay check and determining, by the network node, that the sequence-based anti-replay check rejected the packet. the method further includes performing, by the network node, a time-based anti-replay check, performing, by the network node, a selective anti-replay check, and determining, by the network node, whether to dynamically adjust a time-based anti-replay window size.
