Defense in Depth is a layered cybersecurity strategy that uses multiple, overlapping security controls so that if one control fails, others continue to protect systems, data, and users. The approach spans physical, network, endpoint, application, identity, and data layers, and is widely referenced in NIST, CISA, NSA, and DoD security guidance. This topic indexes APIs and resources that help organizations design, implement, and verify defense in depth controls.
