Which TWO of the following are examples of security principles?
⚠ Common exam trap
ISC2 often tests the distinction between security principles (like least privilege and defense in depth) and security technologies (like encryption, firewalls, and VLANs), trapping candidates who confuse implementation tools with the underlying design concepts.

Correct answer & explanation
✓
Least privilege
Least privilege is a foundational security principle that dictates users, processes, or systems should only be granted the minimum access rights necessary to perform their functions. This reduces the attack surface and limits potential damage from compromised accounts or insider threats. It is a design concept, not a specific technology, which is why it qualifies as a security principle.
