Zero Trust is a cybersecurity model that operates on the principle of “never trust, always verify.” Unlike traditional security approaches that assume users inside a network are trustworthy, Zero Trust requires verification for every user, device, and application attempting to access resources, regardless of their location.
The Zero Trust approach enhances security by continuously monitoring and validating identities, access requests, and device health. It reduces the risk of data breaches, insider threats, and unauthorized access, even if an attacker has already penetrated the network perimeter.
Key principles of Zero Trust include:
Verify Explicitly: Authenticate and authorize every access request based on identity, device, and context.
Least Privilege Access: Grant users and applications only the minimum permissions needed.
Assume Breach: Continuously monitor network traffic and activity to detect anomalies and threats.
Segment Networks: Limit lateral movement within the network to contain potential breaches.
Zero Trust is widely adopted by enterprises, cloud services, and government organizations to strengthen cybersecurity and protect sensitive data in modern hybrid and remote work environments. Technologies supporting Zero Trust include multi-factor authentication (MFA), identity and access management (IAM), encryption, and continuous monitoring tools.
