Why each option
Cisco Stealthwatch (Secure Network Analytics) protects the Things layer by monitoring device traffic for anomalies and the Control Layer by analyzing management and command traffic for threats.
The Things layer represents the physical IoT devices themselves; Stealthwatch monitors network telemetry from these devices to establish behavioral baselines and detect anomalous or malicious traffic indicating compromise.
Endpoints are typically protected by dedicated endpoint security solutions such as Cisco Secure Endpoint rather than Stealthwatch's network flow-based analytics approach.
Internet and Cloud layer traffic is addressed by cloud security solutions such as Cisco Umbrella, not by Stealthwatch which focuses on internal network telemetry.
Access Points are wireless infrastructure components whose security posture is managed by solutions like Cisco Identity Services Engine (ISE) and wireless controllers, not Stealthwatch.
The Control Layer manages communication and commands between IoT devices and their controllers; Stealthwatch analyzes this traffic using behavioral analytics to identify unauthorized commands, policy violations, and lateral movement.
