CASA-VN-000730 - The Cisco ASA VPN remote access server must be configured to validate certificates used for Transport Layer Security (TLS) functions by performing RFC 5280-compliant certification path validation - ipsec-client


A certificate's certification path is the path from the end entity certificate to a trusted root certification authority (CA). Certification path validation is necessary for a relying party to make an informed decision regarding acceptance of an end entity certificate.

Certification path validation includes checks such as certificate issuer trust, time validity, and revocation status for each certificate in the certification path. Revocation status information for CA and subject certificates in a certification path is commonly provided via certificate revocation lists (CRLs) or online certificate status protocol (OCSP) responses.


Configure the ASA to validate certificates used for TLS functions by performing RFC 5280- compliant certification path validation as shown in the example below.

ASA2(config)# crypto ca trustpoint CA_X
ASA2(config-ca-trustpoint)# validation-usage ssl-client
ASA2(config-ca-trustpoint)# validation-usage ipsec-client
