Explanation

Logical security measures protect systems through software, policies, or credentials - not physical barriers. Firewalls (A) are software-based controls that filter network traffic, and strong passwords (B) are credential policies that restrict unauthorized access - both operate in the logical/digital layer without requiring physical interaction.

The remaining choices are physical security controls: key cards (C) and time locks (F) restrict physical access to spaces, camera systems (E) provide physical surveillance, and port security (D) - in this context - refers to physically securing hardware ports or access points rather than a software-enforced network control.

Memory tip: Think "logical = no hands required." If you can enforce it without physically touching anything - through software, rules, or credentials - it's logical. If someone needs to swipe, unlock, or be watched in person, it's physical.

Watch out: Port security can refer to a network switch feature (a logical control), so this question may trip you up. In exam contexts using this wording, it typically refers to the physical securing of ports, so always consider how the term is framed.
