However, it is possible to move certificate validation functionality into a dedicated validation authority authorized by the offline root CA. To better understand how an offline root CA can greatly improve the security and integrity of a PKI, it is important to realize that a CRL is specific to the CA which issued the certificates on the list.

Certificates that support certificate transparency must include one or more signed certificate timestamps (SCTs), which is a promise from a log operator to include the certificate in their log within a maximum merge delay (MMD). [4] [3] At some point within the maximum merge delay, the log operator adds the certificate to their log.
Network access control is a computer networking solution that uses a set of protocols to define and implement a policy that describes how to secure access to network nodes by devices when they initially attempt to access the network. [3]
