The End of Point-in-Time Security
The most dangerous assumption in enterprise security is rarely the one anyone remembers making. It settles quietly into the organization, becoming less a decision than a background condition, until eventually everyone begins treating a moment in time as though it were a durable fact. A system was patched, supplier was assessed, and administrator's access was reviewed. The penetration test found nothing significant and the audit closed without material findings. The evidence exists, neatly timestamped and carefully preserved, carrying all the reassuring weight that documentation has always carried. Then the environment changes around it and almost never dramatically.
