How does Deep Security Manager activate virtual machines within a security group?

Deep Security Manager activates virtual machines within a security group automatically via NSX Security Group tags because this integration enables dynamic security management that is intrinsic to the virtualization environments like VMware NSX.

When a virtual machine is added to a security group, the corresponding tags are dynamically applied based on policies configured within NSX. This capability allows Deep Security to recognize changes in the environment and modify security settings or deploy security services as necessary. Such automation enhances operational efficiency, reduces the potential for human error, and ensures that security policies are consistently enforced across all relevant virtual machines as they are spun up or down.

This automation feature contrasts with manual activation by an administrator, which would not provide the same level of responsiveness and scalability. Additionally, managing firewalls directly would be less effective compared to leveraging the tagging system for real-time updates. Furthermore, tying activation solely to vMotion events does not encompass the broader scenario of dynamic security management across a security group.
