Gives the name of the compiled INSPECT filter/policy currently loaded into the firewall kernel. Because Check Point compiles the security policy into a named filter file before loading it, this string lets an admin verify a policy push actually took effect on this specific gateway rather than trusting the management server's report. Example: fwFilterName reading 'Standard.pf' after a policy install confirms that filter, and not a stale or fallback filter, is what's currently enforcing rules on the box.
