I'm currently reviewing a Check point/Nokia box and a Secure Platform
manager. The settings in Voyager are all good, and likewise the Web
GUI of the SPLAT manager is fine, they're both patched and the policy
is also clean - but I want to ensure the o/s themselves are ok. 

I assume you already checked the rulebase e.g. for SSH-Allow from
outside and VPN- or SecureClient rules, did you?

Unless you have the possibility to check that all binaries (esp. SSH and
other listening servers) are 100% genuine there is no way to ensure
that. IPSO and SPLAT are just plain BSD and Linux after all, so creating
custom binaries is not that much of a problem.


I am concerned that a previous administrator may have left himself
access by the back-door somehow - but am not in a position to rebuild
them to be sure. What else would you lot check for?

Are you *concerned* or do you have no reason to worry and just do "a
proper handover". If you have reason to torry, you really should do a
reinstall and do a thorough audit of the ruleset. 

If management does not allow that, let them give you that order in
writing ("We have received your warning of DATE about a possible
compromise of the firewall system(s) by the former administrator NAME,
but decided against your proposal...") to cover your butt.

Bye

Volker
