Cisco Identity Services Engine (ISE) is a comprehensive identity and access control policy platform that provides network security services for enterprises. It enables centralized management of user identities, devices, and network access policies. Cisco ISE is often used to enforce security policies, providing robust solutions for network access control, identity management, and compliance.
Key Features of Cisco ISE
- Network Access Control (NAC): Allows organizations to enforce policies regarding who or what can access the network. This could be based on user identity, device type, location, or time of access.
Authentication, Authorization, and Accounting (AAA): Supports AAA functions to manage user authentication (verifying identity), authorization (determining permissions), and accounting (tracking usage and activity).
Device Profiling: Automatically detects and classifies devices that attempt to connect to the network (e.g., smartphones, laptops, printers, IoT devices). Based on this profiling, it can apply specific policies based on the type of device (e.g., giving IoT devices limited access compared to laptops).
Guest Access Management: Provides a robust Guest Access solution, which allows temporary or limited network access for visitors or contractors.
BYOD (Bring Your Own Device) Support: Provides seamless support for BYOD environments, allowing employees to use their personal devices on the corporate network securely.
Policy Management: Allows network administrators to define granular access policies based on user roles, devices, locations, or other contextual factors.
Integration with Cisco Security Products: Integrates well with other Cisco products like Cisco ASA Firewalls, Cisco Meraki (cloud-managed networking), and Cisco Stealthwatch (network visibility and security analytics), providing a unified approach to network security.
Centralized Policy Enforcement: Provides centralized control over security policies, which simplifies management, ensures consistency, and reduces the risk of configuration errors.
