Introduction to Cisco Identity Services Engine (ISE)

1. Introduction to Cisco Identity Services Engine (ISE) Cisco Identity Services Engine (ISE) is a comprehensive network access control solution that simplifies and automates network security. ISE offers granular control and visibility into user and device access across your network. www.re-solution.co.uk

2. ISE Deployment Models Centralized Deployment Distributed Deployment Cloud-Based Deployment Multiple ISE instances are deployed across the network, each managing a specific segment. A single ISE instance manages network access control for the entire organisation. ISE is deployed in the cloud, offering scalability and flexibility.

3. Cisco ISE Services Policy Services 1 Access Control ISE enforces network access policies based on user identity, device posture, and network context. Guest Access 2 ISE provides a secure and controlled guest access experience, allowing visitors to connect to the network while adhering to security policies. Wireless Access 3 ISE controls and manages wireless network access, enforcing authentication and security policies for Wi-Fi users. Endpoint Security 4 Cisco ISE Services assesses the security posture of devices connecting to the network, ensuring compliance with security standards.

4. ISE Profiling and Posture Assessment Device Discovery 1 ISE scans the network and identifies connected devices, gathering information such as operating system, MAC address, and hostname. Endpoint Assessment 2 ISE evaluates the security posture of devices, checking for compliance with predefined security standards and policies. Profile Creation 3 ISE uses gathered information to create profiles for each device, categorising them based on their security posture and attributes.

5. ISE Secure Access Control Authentication ISE authenticates users and devices using various methods such as username/password, certificates, and multi-factor authentication. Authorization ISE enforces access permissions based on user roles, device profiles, and network policies. Enforcement ISE restricts or grants access based on authentication and authorization results, ensuring secure network access.

6. ISE Monitoring and Troubleshooting Real-Time Monitoring ISE provides real-time visibility into network activity, allowing administrators to monitor user and device behaviour and identify potential threats. Logging and Reporting ISE logs all events and generates detailed reports, providing valuable insights for troubleshooting and security analysis. Troubleshooting Tools ISE offers a suite of tools for troubleshooting network access issues, helping to identify and resolve problems quickly and efficiently.

7. Conclusion and Key Benefits Enhanced Security ISE provides strong authentication, posture assessment, and access control, significantly enhancing network security.
