Example events

Active Directory Certificate Services encountered errors validating configured key recovery certificates. Requests to archive private keys will no longer be accepted.

Description

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)".„.

Safety assessment

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

Since the certification authority is configured to not accept certificate requests for which private key archiving is configured, and such certificates thus cannot be requested, availability is compromised.

Microsoft rating

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