Microsoft Plugs Nearly 400 Security Holes
Curated from Krebs on Security
Patch management is rarely a source of pride for infrastructure teams, yet it remains the most critical control for reducing your attack surface. Microsoft’s release of nearly four hundred fixes, including patches for actively exploited vulnerabilities, highlights the sheer velocity of modern threat landscapes. For SREs and DevOps engineers, the immediate priority is not just acknowledging the update, but verifying the integrity of your deployment pipelines. Are your automated systems configured to detect and apply these changes without manual intervention? Reliance on manual patching introduces unacceptable lag and human error, allowing known weaknesses to persist in production environments. You must treat these releases as urgent operational tasks rather than administrative chores. Ensure your monitoring tools flag unpatched instances immediately after the release window closes. The concrete takeaway is to automate the verification of patch status across your fleet within hours, not days, to close the gap between disclosure and remediation.
Microsoft today released updates to remedy at least 398 security vulnerabilities in its Windows operating systems and supported software, including one weakness that is already being actively exploited and two others that were publicly detailed prior to today.
