Description: Configures the Minimum allowed TCP Header size. This is active if the First Fragment Denial of Service protection feature is enabled.
What is agentSwitchDenialOfServiceTCPHdrSize?
This object configures the minimum allowed TCP header size, in bytes, that the switch will accept when the First Fragment denial-of-service protection feature is enabled. An admin tunes this threshold to define what counts as an undersized, suspicious TCP header for the fragment-based DoS check. For example, leaving this at its default of 20 bytes matches the standard minimum TCP header length, so anything smaller is flagged as an attack.
