About this tag
Identity security on WindowsForum.com covers the practical challenges of protecting Microsoft Entra ID, Azure Active Directory, and related identity systems in enterprise IT. Recent discussions highlight unverified claims of tenant data dumps, ransomware exposure increasingly tied to identity infrastructure, and the need for identity controls on AI agents like Copilot Studio. Threads also examine Windows Hello for Business abuse scenarios, incomplete advisories for Entra provisioning and elevation-of-privilege vulnerabilities, and how Copilot inherits existing access decisions. The tag focuses on real-world administration, patching gaps, and audit concerns rather than theoretical risks, helping IT teams assess exposure and respond to identity-related threats.
