Fix Recommendation

Edit /etc/ipf/ipf.conf and add rules to block incoming source-routed packets, such as:

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

Reload the IPF rules.
Procedure:
# ipf -Fa -A -f /etc/ipf/ipf.conf

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 check the system for an IPF rule blocking incoming source-routed packets.

Procedure: # ipfstat -i

Examine the list for rules such as:
block in log quick all with opt lsrr
block in log quick all with opt ssrr

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