policy server

The policy server tag on WindowsForum.com covers discussions and security updates related to Microsoft's Network Policy Server (NPS) and Internet Authentication Service (IAS). These servers handle RADIUS authentication in Windows environments. A key topic is the MS15-007 security update, which addressed a denial of service vulnerability in the RADIUS implementation of IAS and NPS. The vulnerability could allow an attacker to disrupt authentication by sending specially crafted username strings. The update was rated Important and focused on preventing service disruptions rather than code execution or privilege escalation. Users discussing policy servers here are typically interested in Windows-based network authentication, security patches, and maintaining reliable RADIUS services.
