What is the concept of zero trust security?

Zero trust security is a cybersecurity model based on the principle of not trusting any entity inside or outside a network by default. This approach assumes that threats could be both external and internal, so it requires verification and authorization for all users and devices trying to access resources on the network, regardless of their location.

Zero trust security uses a variety of technologies and strategies such as multi-factor authentication, least privilege access, network segmentation, continuous monitoring, and encryption to ensure that only authorized users and devices can access the network resources. It effectively redefines traditional approaches to cybersecurity by shifting from the outdated perimeter-based security model to one that focuses on protecting data and resources wherever they are located, be it on-premises, in the cloud, or on mobile devices. This helps organizations better defend against advanced threats and reduce the risk of data breaches.
