Which option correctly classifies a firewall in the lesson’s control categories?

### Why this is right The lesson lists firewalls as technical controls. They are technology-based safeguards used to control network traffic. ### The concept Controls are grouped by how they protect an organization. Technical controls operate through technology, administrative controls guide people and processes, and physical controls restrict access to places or equipment. A firewall is not a policy or a door lock, although it may be part of a broader protection plan. ### The other options - **Administrative control**: policies and training are examples of administrative safeguards, not a firewall. - **Physical control**: secure facility access is physical; a firewall is not a physical access measure. - **Business objective**: an objective is a desired organizational result, not a safeguard. ### Terms - **Firewall**: a technical safeguard that controls network traffic according to rules. ### Remember Classify controls by what they act on: technology, organizational practice, or physical access.
