Cisco ISE (Cisco Identity Services Engine)

Cisco ISE is a network admission control and access layer infrastructure, where people are connecting to network, and we assume they are trusted. Cisco ISE has improved the policy engine which handles the access layer infrastructure.

ISE can authenticate everything in the wired, wireless network and VPN access points.  So, it provides assurance that all the devices on the network should be there. Moreover, it inspects running software on the end points and enables visibility and control over the access network and apply policy enforcement, authentication, identifying on these devices, and controlling your access layer.

Cisco ISE works hand in hand with your network infrastructure and could be implemented as either Radius or Tacacs+ server.  In order to authenticate different devices, 802.1x standard is used so the end points could talk to the switches using various protocols like EAP through the switches that deliver authentication information to Cisco Identity Services  Engine.

What is Cisco ISE Benefits?

ISE by using a robust policy engine, to make a decision on whether or not the end point should get access to the network or is a limited access to the network.  And for that purpose, ISE integrates with identity stores like commonly is Microsoft Active Directory. Most of our customers already have a pretty robust security group architecture there. ISE can leverage all of that existing directory structure to make decisions about what devices should be allowed on the network and what level of access they should get to that.

Furthermore, it employs advanced enforcement capabilities including TrustSec through the use of Security Group Tags (SGTs) and Security Group Access Control Lists (SGACLs) and Supports scalability to support a number of deployment scenarios from small office to large enterprise environments.  The Cisco ISE can be deployed on both physical Cisco SNS Server and virtual environments like VMware, KVM and Hyper-V.

Cisco ISE architecture supports both standalone and distributed (also known as “high-availability” or “redundant”) deployments where one machine assumes the primary role and another “backup” machine assumes the secondary role.

Cisco ISE features distinct configurable personas, services, and roles, which allow you to create and apply Cisco ISE services where they are needed in the network. The result is a comprehensive Cisco ISE deployment that operates as a fully functional and integrated system. Also, Cisco ISE nodes can be deployed with one or more of the Administration (PAN), Monitoring (MnT), and Policy Service personas (PSN).

User authentication policies in Cisco ISE enable you to provide authentication for a number of user login session types using a variety of standard authentication protocols including, but not limited to, Password Authentication Protocol PAP, CHAP, PEAP, and EAP. Cisco ISE specifies the allowable protocol(s) that are available to the network devices on which the user tries to authenticate and specifies the identity sources from which user authentication is validated. At the most fundamental level, Cisco ISE supports 802.1X, MAC authentication bypass (MAB), and browser-based Web authentication login for basic user authentication and access via both wired and wireless networks. For using these features, you should first purchase and install Cisco ISE licenses.

To ensure that the imposed network security measures remain relevant and effective, Cisco ISE enables you to validate and maintain security capabilities on any client machine that accesses the protected network. By employing posture policies that are designed to ensure that the most up-to-date security settings or applications are available on client machines, the Cisco ISE administrator can ensure that any client machine that accesses the network meets.

Mobile Device Management (MDM) servers secure, monitor, manage, and support mobile devices deployed across mobile operators, service providers, and enterprises. MDM enforces policy on endpoints, but it cannot force users to register their device or force remediation. The Profiler service assists in identifying, locating, and determining the capabilities of all endpoints on your network (known as identities in Cisco ISE), regardless of their device types, to ensure and maintain appropriate access to your enterprise network.

The Cisco ISE Profiler function uses a number of probes to collect attributes for all endpoints on your network, and pass them to the Profiler analyzer, where the known endpoints are classified according to their associated policies and identity groups. Cisco pxGrid is used to enable the sharing of contextual-based information from Cisco ISE session directory to other policy network systems such as Cisco Adaptive Security Appliance (ASA).

The pxGrid framework can also be used to exchange policy and configuration data between nodes like sharing tags and policy objects between ISE and third-party vendors, and for non-ISE related information exchanges such as threat information. Cisco ISE provides a native Certificate Authority (CA) that issues and manages digital certificates for endpoints from a centralized console to allow employees to connect to the company’s network using their personal devices.

Cisco ISE has release 6 Cisco ISE patches resolving bugs and vulnerabilities such as log4j issue. Currently the following patches are available for customers:

• Cisco ISE 3 Patch 6
• Cisco ISE 3.1 Patch 3
• Cisco ISE 3.2 Patch 2

Cisco ISE and FMC Integration

By integrating Cisco FMC with Cisco ISE, administrators can used te pxGrid segmentation to classify their  endpoints and monitor their activity continuously.

Cisco ISE License

Cisco ISE licenses can be applied in both traditional and smart ways. In Cisco ISE traditional licensing by purchasing and importing individual licenses based on your needs while, with Cisco ISE smart licenses you are able to monitor Cisco ISE software licenses and endpoint license consumption easily and efficiently with a single token registration. From ISE version 3.x. Cisco ISE licensing can be applied using smart licenses only.

Cisco ISE Smart Licensing

ISE Cisco benefits from  innovative smart licensing method, now Cisco ISE like other products, supports smart licenses. All product instances would be registered on CSSM website with valid smart account containing the specific licenses. Also, Cisco ISE PLR license including Essential license, Advantage license and Premier license all in one, can be used in highly secured environments in order to register all instances with no need to connect to Internet.

Cisco ISE New Version vs. Old Version

About Cisco ISE license changes, When converting existing licenses to the new scheme, the licenses will be migrated using the following rules. While functionality will be retained across licenses, notice that the license count might be different to what the Base/Plus/Apex license count is, and that all licenses will have an expiry date:

Cisco ISE License Tiers

Cisco ISE license models and types are as it follows:

Cisco ISE Essentials license provides user visibility and enforcement features including AAA and 802.1X, Guest (Hotspot, Self-Reg, Sponsored) and Easy Connect (PassiveID).  

Cisco ISE Advantage license enables all Essentials features plus following capabilities:  

• Context Sharing (pxGrid Out/In)  
• Profiling Enforcement  
• AI Endpoint Analytics Enforcement  
• Group-Based Policy (TrustSec)  
• BYOD (+CA, +MDP)  
• RTC (ANC) 
• Profiling Visibility  
• AI Endpoint Analytics Visibility  
• User-Defined Network for Cloud 

Cisco ISE Premier license is full stack license including all Advantage features plus following capabilities: 

• Posture Visibility and Enforcement  
• MDM Visibility and Enforcement  

• TC-NAC Visibility and Enforcement 

Cisco ISE Device Admin license activates all TACACS capabilities on the ISE. 

Cisco ISE VM common license covers VM Small, Medium, and Large licenses for virtual devices. 

Cisco ISE IPsec license supports VPN communication between Cisco ISE Policy Services Nodes (PSNs) and Cisco Network Access Devices (NADs). One Cisco ISE IPsec license is required for every Policy Services Node used for IPsec VPN communication to the NADs. There is a maximum of 150 IPsec tunnels per Policy Services Node. 

Cisco ISE Universal license is an offline and permanent solution for registering all above features in the highly secure networks.  

Cisco ISE License Migration

For Cisco ISE license migration, Migrating to the new licensing scheme requires simple steps to convert your existing PAK licenses to Smart Licenses. ISE will reach out to the Smart Licensing Portal and will enable features and capabilities based on what licenses are available on the portal. As a result, ISE needs network connectivity to reach the CSSM. ISE on the 3.0 release supports PLR, Satellite (On-Premises SSM), or SLR.
