network perimeter

About this tag
The network perimeter is a critical security boundary for Windows environments, especially when Routing and Remote Access Service (RRAS) is used to expose VPN gateways to untrusted networks. Recent vulnerabilities in RRAS, including heap-based buffer overflows and use-of-uninitialized-resource issues, allow remote code execution on unpatched hosts. Administrators must prioritize patching, isolate affected servers, and conduct forensic reviews. Confusion over CVE identifiers in advisories highlights the need to verify vendor KB numbers for each OS build. This tag covers discussions on securing the network perimeter, managing RRAS risks, and responding to threats that target exposed Windows infrastructure.
