TMA-AIX-4.5.3
Ensure clean_partial_conns is enabled
Descripción
The clean_partial_conns parameter determines whether or not the system is open to SYN attacks. This parameter, when enabled, clears down connections in the SYN RECEIVED state after a set period of time. This attempts to stop DoS attacks when a hacker may flood a system with SYN flag set packets. The clean_partial_conns parameter will be set to 1, to clear down pending SYN received connections after a set period of time. Audit: `no -o clean_partial_conns` must report 1.
