What does a firewall policy ACL rule typically include?

A firewall policy Access Control List (ACL) rule is primarily designed to specify what traffic is allowed or denied through the firewall based on specific criteria. The inclusion of source and destination IP addresses is foundational for defining these rules, as firewall ACLs function by evaluating packets against these address criteria to determine whether to allow or block the traffic.

By specifying source and destination IP addresses, a firewall can effectively control the flow of data between different segments of a network or between a network and external sources. This mechanism ensures that only traffic from authorized sources to permitted destinations is permitted, thereby enhancing the security posture of the network.

Other options like encryption methods and protocols, authorized personnel lists, and network bandwidth limits do not typically form part of the basic firewall policy ACL rule structure. While encryption methods and protocols might be relevant to the overall security framework of a network, they do not directly dictate the operation of an ACL rule. Authorized personnel lists pertain to user access control rather than the technical specification of traffic handling in context to firewalls. Network bandwidth limits are related to Quality of Service (QoS) policies rather than access control, which focuses specifically on managing and regulating data traffic based on IP addresses.
