Fix Recommendation

Configure the system to not apply reversed source routing to TCP responses.
# ndd -set /dev/tcp tcp_rev_src_routes 0
Also add this command to a system startup script.

Check Contents

Determine the type of zone that you are currently securing.
# zonename

If the zone is not the global zone, determine if any interfaces are exclusive to the zone:
# dladm show-link

If the output indicates "insufficient privileges" then this requirement is not applicable.

If the zone is the global zone or the non-global zone has exclusive interfaces verify the system does not apply reversed source routing to TCP responses.

# ndd /dev/tcp tcp_rev_src_routes

If the result is not 0, this is a finding.
