Description

Do you know TameMyCerts? TameMyCerts is an add-on for the Microsoft certification authority (Active Directory Certificate Services). It extends the function of the certification authority and enables the application of rule sets to realize the secure automation of certificate issuance. TameMyCerts is unique in the Microsoft ecosystem, has already proven itself in countless companies around the world and is available under a free license. It can be downloaded via GitHub and used free of charge. Professional maintenance is also offered.

See article "Certificate request fails with error message "Cannot archive private key. The certification authority could not verify one or more key recovery certificates. 0x8009400b (-2146877429 CERTSRV_E_NO_VALID_KRA)" ".

Security assessment

The security assessment is based on the three dimensions of confidentiality, integrity and availability.

Since the certification authority refuses to accept certificate requests for which private key archival is configured, and such certificates therefore cannot be requested, availability is affected.

Microsoft's rating

Microsoft evaluates this event in the Securing Public Key Infrastructure (PKI) Whitepaper with a severity score of "Low".
