Firewall Rule Set

Definitions

1. The concrete ordered collection of firewall rules that controls traffic based on addresses, ports, protocols, applications, or identities. The quality of a firewall rule set depends on correctness, maintainability, rule order, and how much outdated access has accumulated over time.

   In plain English: The actual list of firewall rules a device uses.

   Example: "The migration failed because the old firewall rule set had years of undocumented exceptions."
