What is one function of a boundary firewall?

• A. It blocks attackers from accessing the system in the first place
• B. It encrypts data in transit
• C. It stores user credentials
• D. It backs up data

Answer: (A)

A boundary firewall sits at the edge of a network and acts as a gatekeeper, filtering traffic based on security rules. Its main job is to inspect inbound (and sometimes outbound) packets and block anything that doesn’t meet the predefined criteria, preventing potential attackers from reaching internal systems. This is how it stops unauthorized access from the outside in. Encrypting data in transit is handled by encryption protocols like TLS or VPN services, not by a firewall. Storing user credentials belongs to authentication systems or databases, while backing up data is a separate data protection task. So the firewall’s role is to block attackers from accessing the system in the first place.
