What allows you to create a policy that automatically adapts to instance additions, moves, or deletions?

Dynamic Address Groups are a powerful feature that enables the creation of security policies that automatically adapt to changes in the network environment, such as the addition, relocation, or removal of instances. This functionality is crucial for maintaining flexible and responsive security mechanisms in environments where resources frequently change, such as in cloud computing or dynamic data centers.

The key advantage of Dynamic Address Groups is their ability to use predefined criteria (like IP addresses, user attributes, or tags) to populate the group automatically. As instances are added or removed, or as their attributes change, the Dynamic Address Groups will automatically adjust the members of the group accordingly, ensuring that the associated security policies are always relevant and effective without requiring manual updates.

This adaptability significantly simplifies policy management and enhances security posture by ensuring that all resources are appropriately covered by the relevant policies in real time, minimizing the risk of vulnerabilities that could arise from outdated or incorrect policy assignments.
