01 - A Brief History of Zero Trust:
2007: The Defence Industry Security Association (DISA) introduced Black Cloud, a forebear of Zero Trust. It removed visible DNS information from application infrastructure so it could not be detected. This made applications impervious to many forms of network-based attack, including scans, vulnerability exploits, Dos and DDoS attacks.
2011: The Cloud Security Alliance unveils Software Defined Perimeter (SDP). Connectivity in SDP is based on a need-to-know model in which device posture and identity are verified before access is granted.
2010: John Kindervag, principal analyst with Forrester, coins the term Zero Trust.
