ACL

Access Control List (ACL) is a set of rules used to control network traffic by permitting or denying specific packets based on criteria such as IP addresses, protocols, and port numbers. ACLs are commonly used in firewalls, routers, and switches to enforce security policies and manage network access. They allow administrators to define rules for incoming and outgoing traffic, ensuring that only authorized traffic can pass through network devices. ACLs can be used to implement security measures such as network segmentation, traffic filtering, and access control, helping to protect sensitive information and maintain network integrity.
