Security ArchitectureQuestion 26 of 100
Layering multiple independent security controls so that one failure does not cause a breach is called:

b.Defense in depth
c.Least privilege
d.Air gapping
Explanation
Defense in depth stacks overlapping controls across people, process, and technology so no single failure is catastrophic. If one layer is bypassed, others still protect the asset. It reflects the assumption that any one control can fail.
