Network ACLs

Network Access Control Lists (ACLs) are essential tools for managing network security. An ACL is a set of rules that determine which traffic is allowed or denied across a network interface. With ACLs, you can control the flow of traffic based on a variety of criteria, such as source IP address, destination IP address, port, and protocol.
