Microsoft’s August cumulative update for Windows Server 2019, KB5063877 (released August 12, 2025), finally closes out a high‑visibility clustering regression introduced by the July rollout: a Cluster Service failure that caused repeated service restarts, node quarantines and virtual machine...
Microsoft's warning about servicing Windows installation images with a fresh Microsoft Defender package is a timely reminder that new installations can inherit an invisible security gap: the antimalware binaries and definitions embedded in ISO/WIM/VHD images become stale the moment an image is...
Cisco has pushed an urgent patch for a maximum‑severity remote code execution flaw in its Secure Firewall Management Center (FMC) software that allows an unauthenticated attacker to inject and execute arbitrary shell commands on affected appliances when RADIUS authentication is enabled for...
Windows 11 ships with a far stronger security baseline than its predecessors, but real-world attackers and configuration gaps still find workarounds—meaning Defender and Windows Security are necessary, not sufficient, for modern threat defense.
Background
Windows 11’s built-in...
Windows ships with dozens of features and background services designed to improve convenience — but those conveniences are also additional points of entry for attackers. A recent how‑to-style guide compiled a short list of commonly unnecessary capabilities that many users can safely disable to...
