As for the latter though, yes it deny's all by default (no need to insert

Although IMHO it's good practice to explicitly state your deny all rule.  It
improves clarity overall, which is never a bad thing.

cheers!

Subject: [fw-wiz] cisco pix does not log traffic targetted to itself?

My cisco pix firewall is logging denied traffic normally. However when I
tried using a scanner to scan the cisco pix firewall itself, a few open
ports were discovered but no traffic of the scan was captured in the log.
In
other words, the firewall didn't log my scan activity. What can I do to to
ensure that any activity targetted to my firewall is logged?

Also is it true that the cisco pix firewall deny all traffics that is not
permitted in the rule-base BY DEFAULT? Is there a need to insert a last
rule
that deny any to any?
