Frequently Asked Questions
Welcome to our FAQ section, where we aim to address common inquiries about hiring for Cisco Identity Services Engine (ISE) Administrators within your organization. The following questions and answers will guide you in identifying and attracting the right talent to drive your company’s success.
Cisco Identity Services Engine (ISE) is a comprehensive security and network access policy management platform that enables enterprises to manage access and security policies across their wired, wireless, and VPN networks. The platform is designed to help organizations enforce compliance, enhance infrastructure security, and streamline service operations.
Key Features of Cisco ISE
1. Centralized Policy Management
Cisco ISE acts as a centralized policy management point that allows network administrators to create and manage access policies based on the rich contextual data the system gathers. This includes user identity, device type, device health, location, time, and network access method.
2. Contextual Identity and Device Profiling
ISE gathers and utilizes contextual information about users and devices to enforce security policies. It integrates with Active Directory and other identity stores to authenticate and authorize users and devices. The device profiling capabilities allow ISE to detect the type of device (like smartphones, tablets, laptops) trying to access the network.
3. Secure Network Access
ISE facilitates secure network access through technologies such as:
- 802.1X: For controlled network access to all endpoints, including IoT devices.
- MAC Authentication Bypass (MAB): For devices that do not support 802.1X.
- Web Authentication: For guests and other exceptions.
4. TrustSec
TrustSec technology simplifies the provisioning and management of access control policies using security group tags (SGTs). This allows for the implementation of policies that are dynamically adjusted based on the security posture of an endpoint.
5. Guest Access Management
ISE provides a customizable guest access experience, allowing visitors to log in through a self-service portal that can enforce varying levels of access. This feature is crucial for managing guest access in a secure and regulated manner.
6. Compliance Enforcement
Cisco ISE continuously monitors connected devices to ensure they comply with the organization’s security policies. It can enforce corrective actions, such as quarantining a device or denying network access if it fails to meet the required security posture.
7. Threat-Centric NAC (Network Access Control)
Integration with other security products like Cisco’s Advanced Malware Protection (AMP) and Stealthwatch allows ISE to adapt policies based on threat intelligence and security alerts.
Architecture and Components
1. Administration Node (PAN)
Handles all system-related configurations and management of the ISE deployment, including policy configuration, logging, and overall system health.
2. Policy Service Node (PSN)
Responsible for handling all policy enforcement, session, and authentication, authorization, and accounting (AAA) functions. Multiple PSNs can be deployed to ensure scalability and redundancy.
3. Monitoring and Troubleshooting Node (MnT)
Collects and analyzes logging data from all the other nodes. It provides advanced monitoring, reporting capabilities, and troubleshooting tools.
4. pxGrid (Platform Exchange Grid)
Allows ISE to exchange information with other security products such as firewalls, intrusion prevention systems (IPS), and other threat defense tools to enhance visibility and control across the network.
Deployment Scenarios
Cisco ISE can be deployed on-premises with appliances or as a virtual machine in data centers. It can also be integrated into cloud environments, extending its capabilities across traditional and modern IT landscapes.
Use Cases
- Secure BYOD: Enabling secure access for employee-owned devices while ensuring compliance with corporate security policies.
- IoT Security: Managing access and segmenting IoT devices to minimize the risk of lateral movement in case of breaches.
- Incident Response: Quickly containing threats by dynamically controlling network access for affected endpoints.
Cisco ISE is integral to many enterprise networks due to its extensive feature set that addresses complex security challenges of today’s diversified and mobile-first environments.
