Explanation

A firewall's core function is to prevent unauthorized access to a network (C) by inspecting incoming and outgoing traffic against a defined rule set and blocking traffic that does not meet those rules. Authentication (A) is handled by identity management systems. Remote access (B) is provided by VPNs or remote desktop solutions. Monitoring for malicious activity (D) is the role of an Intrusion Detection System (IDS). A firewall enforces access control at the network boundary - it is a gatekeeper, not a monitoring or authentication tool.
