Zero-trust security refers to a security model backed by rigorous identity authentication tools. It aims to limit access to applications and data to only a certain group of authenticated and authorized users. This can also provide high-level security to users and applications from malicious actors online.
Most zero-trust security models follow the “verify, then trust” system. This means that before any access request to an application, device, or site is approved, the user first has to provide accurate user credentials.
This concept came about when more businesses were starting to move towards further digitization and became more dependent on online networks.
