Which feature of Cisco ISE helps in analyzing traffic patterns for better security?

The feature of Cisco ISE that helps in analyzing traffic patterns for better security is the packet capture capabilities. This functionality allows administrators to capture and analyze network traffic in real-time or from specific points within the network. By examining the data packets flowing through the network, security professionals can identify anomalies, monitor user behavior, and detect potential threats. This in-depth visibility into traffic patterns enables better-informed decisions regarding security policies and adjustments needed to protect the network.

While user role management, device access limitation, and periodic network updates are essential features for managing access control and overall network security, they do not directly contribute to the analysis of traffic patterns. User role management focuses on defining access permissions based on user roles, device access limitation restricts device connectivity based on predefined policies, and periodic network updates are crucial for ensuring that the ISE system has the latest definitions and security protocols in place. However, these features do not provide the traffic analysis needed for enhancing security measures like packet capture does.
