Zero Trust Architecture (ZTA) is a security framework that moves away from traditional network-based security models. By adhering to these principles, ZTA aims to create a more secure environment where trust is earned, not assumed. It focuses on protecting data and resources regardless of where users or devices are located.
Here are the core principles of ZTA:
Never Trust, Always Verify: This principle emphasizes that no user or device should be automatically trusted, regardless of location (internal network or external) or ownership (company-owned or personal device). Every access attempt needs to be verified through strong authentication methods.
Least Privilege: Users and devices should only be granted the minimum level of access required to perform their tasks. This minimizes the potential damage if a breach occurs.
Assume Breach: Security teams should operate under the assumption that a breach has already occurred or is ongoing. This proactive approach fosters continuous monitoring and rapid response to suspicious activity.
Continuous Monitoring: User behavior and system activity should be monitored continuously to identify anomalies and potential threats.
Micro-segmentation: Networks should be segmented into smaller, more secure zones. This limits the potential impact of a breach by restricting lateral movement within the network.
