To set up zero trust in hybrid environments, organizations should start by identifying all assets and resources within their network, including on-premises and cloud-based systems. This inventory should include applications, data, devices, and users. Once all assets are identified, organizations can begin implementing strict access controls based on the principle of least privilege. This means granting users access only to the resources they need to perform their job functions, and nothing more. Access should be granted on a per-session basis, with continuous monitoring and authentication required for each session.

Next, organizations should implement network segmentation to create micro-perimeters around critical assets. This involves dividing the network into smaller segments and restricting traffic flow between them. By segmenting the network, organizations can contain potential threats and limit the lateral movement of attackers. Network segmentation should be combined with encryption to protect data both in transit and at rest. This ensures that even if an attacker gains access to a segment of the network, the data within that segment remains secure.

Finally, organizations should adopt a comprehensive monitoring and analytics solution to continuously assess the security posture of their hybrid environment. This includes monitoring user behavior, network traffic, and system logs for any suspicious activity. Machine learning and artificial intelligence can help organizations identify anomalies and potential threats in real-time. By continuously monitoring the environment, organizations can quickly detect and respond to security incidents, minimizing the impact of potential breaches. Additionally, regular security audits and penetration testing should be conducted to identify and address any vulnerabilities in the zero trust architecture.
