(also Extended Access Lists)
Extended ACLs definition
Extended Access Control Lists (ACLs) operate as a network security mechanism. That mechanism operates under specific rules that allow or block traffic within a network. They are usually used in firewalls and routers. Furthermore, Extended Access Control Lists are more customizable than standard ACLs. Not only that they can grant access rights to specific system objects, but extended ACLs can also serve as an extension of a common ACL, and the parameters can be configured to the specified order. These features can increase network security by enforcing security policies and mitigating unauthorized access or possible attacks.
The benefits of extended ACLs
- Unlike standard ACLs, extended ACLs offer greater control over the traffic flows. That allows administrators to choose and specify which traffic is allowed or should be blocked.
- More control with extended ACLs implements more security and lets administrators protect networks from malicious activity or prevent specific applications from misuse.
- Extended ACLs give the possibility to be applied inbound or outbound, which lets network administrators control and filter traffic on the ingress and egress of the whole network.
