Ensure ipsrcrouteforward is disabled

SrednjaNivo 1Automatskaaix

Opis

The ipsrcrouteforward parameter determines whether or not the system forwards IPV4 source-routed packets. The ipsrcrouteforward will be set to 0, to prevent source-routed packets being forwarded by the system. This would prevent a hacker from using source-routed packets to bridge an external facing server to an internal LAN, possibly even through a firewall. Audit: `no -o ipsrcrouteforward` must report 0.

Kako se proverava

Metod provere: Komanda ljuske

Očekivani izlaz: ipsrcrouteforward=0

Kako se ispravlja

Metod ispravke: Smernica ili zakrpa infrastrukture

no -p -o ipsrcrouteforward=0 (sets the running value and makes it persistent in /etc/tunables/nextboot)
