In the evolving landscape of cybersecurity, organizations are constantly seeking robust frameworks to protect their assets from a myriad of threats. The Zero Trust Architecture (ZTA) and Layered Security Model (LSM) emerge as two paramount paradigms that address these concerns. Zero Trust, as the name suggests, operates on a foundational principle of "Never Trust, Always Verify." It posits that trust should not be inherently granted based on location (inside or outside the organizational perimeter) but should be established through rigorous verification processes. This approach emphasizes the importance of continuous validation of entities trying to access organizational systems, ensuring that every access request is authenticated, authorized, and encrypted. Complementing the Zero Trust approach is the Layered Security Model, also known as Defense in Depth. This model advocates for multiple layers of defense mechanisms placed throughout an IT system, creating a multi-faceted barrier against potential threats.
