Zero Trust
Zero Trust is an IT security model in which no user, device, service or network is automatically trusted. Every access request is verified, regardless of whether it comes from the corporate network, the cloud or from outside the organization.
How it works and how it is used
Zero Trust is based on the principle “Never trust, always verify.” This means that every access request to applications, systems or data must be clearly authenticated, authorized and reviewed on a regular basis. Several factors are taken into account, such as the user’s identity, the condition of the device, the location, the risk level of the request and the permissions required.
An important part of Zero Trust is the principle of least privilege. Users and systems only receive the access rights they actually need for their specific task. In addition, multi-factor authentication, network segmentation, continuous monitoring and automated security checks can be used.
Zero Trust is commonly used in modern IT environments where employees work remotely, applications run in the cloud or many different devices access corporate resources. The goal is to make unauthorized access more difficult, reduce security risks and better protect sensitive data.
Practical examples
- Signing in to corporate applications only with multi-factor authentication
- Access to sensitive data only for authorized roles or teams
- Checking the condition of a device before allowing access to internal systems
- Segmenting networks so attackers cannot move freely within the environment
- Automatically blocking or triggering additional checks in case of unusual access behavior
