Why patching prevents cyber disasters

This article advocates timely, comprehensive patching across operating systems, applications, and network devices to prevent cyber incidents, citing examples such as WannaCry/EternalBlue, Log4j, and a Microsoft Word zero-day to illustrate how attackers rapidly exploit known flaws; it advises validating patch coverage beyond registry checks, improving visibility with hash-based detection (including portable apps), performing spot checks, testing rollouts, hardening environments (e.g., blocking Office-to-PowerShell), staying current with Patch Tuesday releases, and treating firewall/VPN patching as essential within a layered defense.
