Access Control Server (ACS) A component that operates in the Issuer Domain, that verifies whether authentication is available for a card number and device type, and authenticates specific Cardholders.

Access Control Server (ACS) is in the issuer domain (banks) of 3-D Secure protocols. An ACS which is used to support cardholder authentication is required to be maintained by each card issuer. By providing their username and password, a customer is able to authenticate to the ACS which then signs the result as either a success or a failure.

As mentioned earlier, the security protocol involves inputs from the card issuer and this is made possible by using ACS to verify the status of the card as well as authenticating the transaction.
