Zero trust architecture (ZTA)

Zero Trust Architecture (ZTA) is a security model based on the principle of "never trust, always verify." It is developed with the understanding that threats can exist outside as well as inside the network. Therefore, instead of trusting anything inside or outside the security perimeter by default, every access request is thoroughly verified before granting access.

Core Principles of Zero Trust Architecture

Least-Privilege Access

Assign minimum access — or permissions — needed for users (or systems) to accomplish tasks, reducing the attack surface.

Micro-Segmentation

Divide the network into secure zones and enforce security policies at each zone, limiting lateral movement of threat actors within the network.

Explicit Access Control

Define and enforce access policies based on the needs of individual users or systems, regardless of their location (inside or outside the network).

User Authentication and Authorization

Rigorously authenticate user identities and authorize their access based on defined access controls, often involving multi-factor authentication (MFA).

Application and Traffic Analysis

Continuously monitor and analyze the traffic and applications to identify and respond to any anomalous behaviour or security incidents promptly.

Implementation in Palisade

In the context of Palisade, the Zero Trust Architecture is implemented meticulously to safeguard sensitive information and customer assets. Every access request to sensitive data or operations, whether it originates from inside or outside the organization, is authenticated, verified, and validated. This rigorous approach ensures that only legitimate and authorized requests gain access, providing an additional layer of security and reducing the risk of unauthorized access and data breaches.
