Fewer can prove every allow rule is inspected, logged, owned, and still required.</p> <p>The gap between those two things is where audits become painful. Multiple firewall admins, emergency changes at 2am, quarterly reviews that turn into archaeology digs, vendor access rules that were &ldquo;temporary&rdquo; in February and are still there in October. Nobody disabled them because nobody noticed they were still there. No alert fires when a rule that was supposed to be temporary quietly becomes permanent.</p>
