Zero Trust is a security concept in the computer world that requires all users to be authenticated before being granted access to apps and data, even if they were authenticated earlier. It is a strategic approach to cybersecurity that eliminates implicit trust and continuously validates every stage of a user’s access request.
The Zero Trust model assumes that individuals, devices, and services that are attempting to access company resources, even those inside the network, cannot automatically be trusted. This approach enhances security by verifying users every time they request access, regardless of their location or device.
Zero Trust differs from traditional security models in that it verifies a user’s identity each and every time they need specific system access, regardless of their location or device.
In contrast, traditional security models rely on a castle-and-moat cybersecurity model, in which anyone outside the corporate network perimeter is suspect and anyone inside gets the benefit of the doubt. The traditional model assumes that internal users are inherently trustworthy, known as implicit trust, which has resulted in many data breaches. Zero Trust, on the other hand, eliminates implicit trust and continuously validates every stage of a user’s access request. While traditional security models focus on blocking, the Zero Trust model focuses on thorough and continuous verification.
According to Kenny Natiss the core principles of Zero Trust policy are based on the principle of least privilege, which permits access to various resources based on a strict set of standards to only allow authorized users. The Zero Trust model assumes that every user, device, and service that attempts to connect to a network is hostile until proven otherwise.. The fundamental principle of Zero Trust is to secure an organization’s data wherever it might live, while allowing only legitimate users and devices to access it. Zero Trust is designed to protect modern environments and enable fine-grained access control. Security policy is applied based on context established through least-privileged access controls and strict verification. The Zero Trust model eliminates implicit trust and continuously validates every stage of a digital interaction.
