Disable Network Routing

MediumLevel 1Automatedsolaris

Description

The network routing daemon, in.routed, manages network routing tables. If enabled, it periodically supplies copies of the system's routing tables to any directly connected hosts and networks and picks up routes supplied to it from other networks and hosts. Routing Internet Protocol (RIP) is a legacy protocol with a number of security weaknesses including a lack of authentication, zoning, pruning, etc. Audit: ipv4/ipv6 routing and forwarding must be disabled both persistently and currently (routeadm -p).

How it is checked

Audit method: Shell command

shell

command -v routeadm >/dev/null 2>&1 || exit 1; out=$(routeadm -p 2>/dev/null) || exit 1; r=compliant; for k in ipv4-routing ipv4-forwarding ipv6-routing ipv6-forwarding; do l=$(printf '%s\n' "$out" | grep "^$k "); case "$l" in *persistent=disabled*current=disabled*|*current=disabled*persistent=disabled*) ;; *) r="$k: $l";; esac; done; echo "$r"

Expected output: compliant

How it is fixed

Fix method: Guidance or infrastructure patch

routeadm -d ipv4-forwarding -d ipv4-routing -d ipv6-forwarding -d ipv6-routing; routeadm -u
