Zero Trust Principles
Zero Trust principles are a set of security concepts that aim to protect an organization’s systems, data, and resources by assuming that all access attempts are potentially malicious, even if they are from within a secure network, resource, or application. The following are the key principles of Zero Trust:
- Never trust, always verify: All users, devices, and applications must be verified and authenticated before being granted access to any resources.
- Least privilege access: Access should be granted on a need-to-know basis, and users should only be granted the minimum level of access required to perform their job functions.
- Assume breach: Assume that an attacker has already compromised a secure resource and acts accordingly to limit the attacker’s access and ability to move laterally within the network, system, application, or database.
- Micro-segmentation: Segment resources into small, isolated zones to limit the spread of a breach and prevent attackers from moving laterally.
- Continuous monitoring: All access attempts must be continuously monitored for signs of suspicious behavior, and appropriate action must be taken in response to any suspicious activity.
- Contextual awareness: Security policies and access controls must be based on contextual awareness, such as the user’s role, device location, and sensitivity of the data being accessed.
By following these principles, organizations can better protect their systems, data, and resources from cyber threats. Zero Trust principles help organizations to reduce their attack surface, minimize the impact of a breach, and improve their overall security posture by continuously verifying the identity of users and devices and evaluating the risk profile of access requests.
