Ensure ipsrcrouteforward is disabled

보통레벨 1자동aix

설명

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.
