Zerotrustmalli

Zerotrustmalli, often referred to as the Zero Trust model, is a security framework that operates on the principle of "never trust, always verify." Instead of assuming that everything inside an organization's network perimeter can be trusted, Zero Trust requires that all users, devices, and applications be authenticated and authorized before being granted access to resources. This approach fundamentally shifts the security paradigm from perimeter-based defense to identity-centric control.

The core tenets of the Zero Trust model include verifying explicitly, using least privilege access, and assuming breach. Verifying explicitly means that authentication and authorization are performed for every access request, regardless of origin. Least privilege access ensures that users and devices are only granted the minimum permissions necessary to perform their intended functions. Assuming breach acknowledges that threats can originate from both outside and inside the network, and therefore security measures should be in place to detect and contain them.

Implementing a Zero Trust model involves a combination of technologies and policies. These can include multi-factor authentication, micro-segmentation of networks, identity and access management (IAM) solutions, and continuous monitoring of user and device behavior. The goal is to create a more resilient security posture that can adapt to evolving threats and the increasing complexity of modern IT environments, including cloud computing and remote workforces. By removing implicit trust, Zero Trust aims to reduce the attack surface and limit the damage that can be caused by a security incident.
