Explanation

This statement is TRUE and reflects the textbook definition of a firewall. Firewalls act as gatekeepers between trusted internal networks and untrusted external networks (such as the internet). They inspect packets against a defined rule set (access control lists or policies) and either allow or block traffic accordingly. Firewalls can be implemented in hardware, software, or as a combination of both, and operate at various OSI layers depending on type (packet filter, stateful inspection, application layer).
