Securing the perimeter is obsolete

The traditional perimeter-based approach to security is no longer sufficient in the age of cloud computing, mobility, and the Internet of Things (IoT). The concept of a "perimeter" has become obsolete, prompting the adoption of the Zero Trust security model. Zero Trust operates on the premise that no user or device is inherently trustworthy, necessitating the verification of each request before granting access.

To mitigate the risks of these events, it is essential that a professional incident response team is available to triage and effectively resolve these incidents quickly and effectively.

Introducing micro-segmentation

Micro-segmentation compliments the Zero Trust model by providing granular control over network access and reducing the scope of potential attacks. It allows organizations to divide their network into smaller, isolated segments, significantly reducing the risk of a breach. This approach makes it more challenging for a malicious actor to move laterally within the network.

As a crucial aspect of Zero Trust security, micro-segmentation enforces the principle of "least privilege," ensuring that users and devices only have access to the resources necessary to perform their tasks. This reduces the attack surface and helps to prevent attackers from accessing sensitive data or systems.

With Zero Trust, even if a device or user is compromised, the attacker still needs to pass through multiple levels of verification to reach sensitive data or systems. And with micro-segmentation, even if the attacker manages to bypass some of the Zero Trust controls, they will still be confined to a smaller segment of the network, making it easier for security teams to detect and respond to the threat.

Four Best Practices of Micro-segmentation in a Zero Trust Model

  • Perform a network assessment

    Analyze your network thoroughly, identifying assets, applications, and services to determine necessary segments and relevant security policies.

  • Create a segmentation plan

    Develop a plan considering user roles, device types, application dependencies, and data sensitivity to guide micro-segmentation implementation within the Zero Trust model.

  • Apply least privilege access controls

    Limit user and device access to essential resources, minimizing unauthorized access and lateral movement in the network.

  • Monitor and analyze network traffic

    Employ real-time monitoring and advanced analytics tools to detect anomalies, identify potential threats, and respond promptly to security incidents.
