Oracle 10g Certificate Validation with Certificate Revocation Lists (CRLs)

Certificate validation is an important element of enabling public key infrastructure (PKI) in an enterprise. If you use SSL in an Oracle environment, you can now validate the certificates presented by servers and clients for authentication. First off though, what the heck is a CRL?

Certificate Revocation Lists

Typically, a certificate from a Certificate Authority (CA) that binds a public key pair to a user identity is only valid for a specified period of time. However, certain security-related events, such as user name changes or compromised private keys, could render a certificate invalid before the validity period actually expires.

If this happens, the CA will revoke the certificate and add its serial number to a Certificate Revocation List (CRL). CAs will periodically publish CRLs to alert the user population of their certificates when it is no longer acceptable to use a particular public key to verify its associated user identity.

When servers in an Oracle environment receive client certificates, they check its validity date, signature, and revocation status. As you can guess, the certificate revocation status is checked by validating it against published CRL lists. When certificate revocation status checking is turned on in Oracle Database 10g, the server will search for the appropriate CRL depending on how this feature has been configured. The server will search for CRLs in the following locations:

  • The local file system
     

  • The specified Oracle Internet Directory

When the CRL cannot be found on the local file system, the server searches the CRL directory subtree in the Oracle Internet Directory by using the CA’s distinguished name (DN) and the DN of the CRL Directory subtree.
