Administrator Guide

NOTE: A CA certificate can also be revoked.
Verifying Server certificates
Verifying that server certificates are mandatory in the TLS protocol.
As a result, all TLS-enabled applications require certificate verification, including Syslog servers. The system checks the Server certificates
against installed CA certificates.
Verifying client certificates
Verifying that client certificates are optional in the TLS protocol and is not explicitly required by Common Criteria.
However, TLS-protected Syslog and RADIUS protocols mandate that certificate-based mutual authentication be performed.
Event logging
The system logs the following events:
• A CA certificate is installed or deleted.
• A self-signed certificate and private key are generated.
• An existing host certificate, a private key, or both are deleted.
• A host certificate is installed successfully.
• An installed certificate (host certificate or CA certificate) is within seven days of expiration. This alert is repeated periodically.
• An OCSP request is not answered with an OCSP response.
• A secure session negotiation fails due to invalid, expired, or revoked certificate.
