About this tag
The SCEP tag on WindowsForum.com covers discussions about the Simple Certificate Enrollment Protocol, a standard for automated certificate enrollment in network environments. Recent threads focus on Microsoft's Kerberos hardening campaign, which mandates strong certificate binding by September 2025, affecting SCEP-based certificate deployments on Windows domain controllers. Additionally, two critical vulnerabilities, CVE-2024-43544 and CVE-2024-43541, were disclosed in October 2024, both posing Denial of Service risks to systems using SCEP. Topics include migration from weak certificate mappings, registry workarounds, and security implications for enterprise IT. Administrators will find guidance on preparing for the upcoming enforcement deadline and mitigating SCEP-related threats.
