Check: GEN003608

Solaris 10 SPARC STIG: GEN003608 (in versions v2 r4 through v1 r19)

Title

Proxy ARP must not be enabled on the system. (Cat II impact)

Discussion

Proxy ARP allows a system to respond to ARP requests on one interface on behalf of hosts connected to another interface. If this function is enabled when not required, addressing information may be leaked between the attached network segments.

Check Content

Determine if the system has non-local published ARP entries. Procedure: # arp -a If any entries have the flag P and no flag L, they are non-local published entries, and this is a finding.

Fix Text

Remove non-local published ARP entries from the system. Procedure: # arp -d <host> Check system initialization files for any commands creating published ARP entries (such as "arp -s <host> <ether> pub" or "arp -f") and removing them.
