What do security groups in Azure IoT facilitate?

Security groups in Azure IoT facilitate centralized management of device security by allowing users to group devices that share similar security requirements or policies. This capability enables administrators to apply security configurations and access controls uniformly across all devices within a specific group. By organizing devices into security groups, it becomes easier to manage permissions, monitor security status, and enforce compliance policies effectively.

This centralized approach enhances the security posture of an IoT solution by simplifying the management of security settings and making it easier to respond to security incidents. Additionally, it helps ensure that all devices within a given group adhere to the same security standards, minimizing the risk of vulnerabilities due to inconsistencies in configuration.
