The firewall ruleset analysis should be easy to do in ruling out holes in
your existing rules. However, another thing to consider is an System
Integrity Verification (SIV) tool like fcheck or similar This is assuming
the Nokia is running SunOS and not the appliance version which an SIV
wouldn't apply. SIV's check, and track moving forward, the MD5 hashes of
whatever you want to monitor (usually rootkit targets like modified ls, ps,
top, etc). Any modifications to those binaries will be flagged or blocked
depending on the tool you use.
