The root role is required.

# pfedit /etc/ipf/ipf.conf

For Solaris 11, 11.1, 11.2, and 11.3 that use IP Filter dd rules to block outgoing source-routed packets, such as:

block out log quick all with opt lsrr
block out log quick all with opt ssrr

Reload the IPF rules.

# ipf -Fa -A -f /etc/ipf/ipf.conf

For Solaris 11.3 or newer that use Packet Filter remove or modify any rules that include "allow-opts".

Reload the Packet Filter rules:
# svcadm refresh firewall:default

Check Contents

Determine the OS version you are currently securing.
# uname –v

Solaris 11, 11.1, 11.2, and 11.3 use IP Filter. To continue checking IP Filter, the IP Filter Management profile is required.

Check the system for an IPF rule blocking outgoing source-routed packets.

# ipfstat -o

Examine the list for rules such as:
block out log quick from any to any with opt lsrr
block out log quick from any to any with opt ssrr

If the listed rules do not block both lsrr and ssrr options, this is a finding.

For Solaris 11.3 or newer that use Packet Filter, the Network Firewall Management rights profile is required.

Ensure that IP Options are not in use:
# pfctl -s rules | grep allow-opts

If any output is returned, this is a finding.
