A security model that requires strict identity verification for every user and device attempting to access resources, regardless of whether they are inside or outside the network perimeter.
Description
Zero Trust is a security framework that operates under the principle of 'never trust, always verify.' In the context of Non-Human Identity Management, it emphasizes that all identities, including those of devices, applications, and services, must be authenticated and authorized before accessing sensitive resources. This approach mitigates the risks associated with compromised credentials, insider threats, and lateral movement within a network. Each access request is treated as though it originates from an open network, necessitating rigorous verification processes, including multi-factor authentication, continuous monitoring, and granular access controls. Zero Trust architectures often employ micro-segmentation, ensuring that even if a device is compromised, the attacker has limited access to the overall network. By applying Zero Trust principles, organizations can enhance their security posture, especially as the dynamics of work shift toward cloud environments and remote access. This model is increasingly relevant as organizations adopt IoT devices and automated processes, necessitating robust identity management strategies for non-human entities.
Examples
- Using API tokens that require regular rotation and strict access policies for automated services.
- Implementing machine identity management to ensure that only verified applications can communicate with each other.
Additional Information
- Zero Trust architecture often involves technologies like identity and access management (IAM) and security information and event management (SIEM).
- The concept is widely adopted in cloud security strategies, especially in environments utilizing microservices and containers.
