Cyber Defense Magazine, Friday, November 1st, 2024
It was 2010 when term 'Zero Trust' was coined by John Kindervag, a thought-leader in Cyber Security industry with a motto of 'never trust, always verify'. Many high-tech organizations like Google analyzed the benefits of Zero Trust security and announced its adoption a few years later.
Zero Trust is a security framework of eliminating implicit trust from entities whether inside or outside of organization's environment by authenticating, authorizing, and continuously validating them for security at each stage, to grant and keep access to application and data.
Zero Trust security includes several implementation models including Zero Trust Architecture (ZTA), Zero Trust Network Access (ZTNA), and Zero Trust Edge (ZTE) that are described below in brief. However, all these models are built around the same core concepts of Zero Trust security.
