In the implementation of security on multiple devices, how do ASA ACLs differ from Cisco IOS ACLs?

  • Cisco IOS routers utilize both named and numbered ACLs and Cisco ASA devices utilize only numbered ACLs.
  • Cisco IOS ACLs are configured with a wildcard mask and Cisco ASA ACLs are configured with a subnet mask.
  • Cisco IOS ACLs are processed sequentially from the top down and Cisco ASA ACLs are not processed sequentially.
  • Cisco IOS ACLs utilize an implicit deny all and Cisco ASA ACLs end with an implicit permit all.

Explanation: The Cisco IOS ACLs are configured with a wildcard mask and the Cisco ASA ACLs are configured with a subnet mask. Both devices use an implicit deny, top down sequential processing, and named or numbered ACLs.
