For your high security data access in your organization, you will want to make sure you use some sort of revocation process with an e signature. Most organizations will use the Certificate Revocation List process as one method. With this method it can take time to send the information over your network to revoke certificates. An alternative method that is used for instant revocation is the Online Certificate Status Protocol.
Why Do Organizations Need to Cancel and Revoke an E Signature?
Organizations need to cancel and revoke an e signature whenever an employee leaves the company or access is no longer required. While you can set an expiration date within the signature certificate, sometimes this date will be after the time you actually want to revoke the certificate. This is where revocation processes are necessary in order to remove access when it is required, rather than waiting until the certificate would expire.
