Description: Enables or Disables the TCP Offset Denial of Service protection feature.
What is agentSwitchDenialOfServiceTCPOffsetMode?
This setting enables or disables protection against TCP packets carrying an invalid or suspicious fragment offset value. An admin enables it to have the switch drop packets whose offset field is inconsistent with a legitimate fragment, a pattern often used in DoS exploits. For example, turning this on blocks a crafted packet whose offset would otherwise cause overlapping or malformed reassembly on the receiving host.
