Latest Contents.Cisco Identity Services Engine ISE is a market leading, identity-based network access control and policy enforcement system.

ISE allows an administrator to centrally control access policies for wired wireless and VPN endpoints in the network. Through the sharing of vital contextual data with technology partner integrations and the implementation of Cisco Scalable Group Policy for software-defined segmentation, Cisco ISE transforms the network from simply a conduit for data into a security enforcer that accelerates the time to detection and time to resolution of network threats.

The document provides best practice configurations for a typical environment. Cisco ISE Profiling Services provides dynamic detection and classification of endpoints connected to the network. Using MAC addresses as the unique identifier, ISE collects various attributes for each network endpoint to build an internal endpoint database. The classification process matches the collected attributes to prebuilt or user-defined conditions, which are then correlated to an extensive library of profiles.

These profiles include a wide range of device types, including mobile clients iPads, Android tablets, Chromebooks, and so ondesktop operating systems for example, Windows, Mac OS X, Linux, and othersand numerous non-user systems such as printers, phones, cameras, and game consoles. Cisco ISE Profiling also covers the Internet of Things IoT by classifying building automation including devices used to control heating, ventilation, and air conditioning HVACpower and lighting systems, as well as vertical-specific endpoints such as healthcare patient monitors and imaging devices, as well as manufacturing controllers and sensors.

Once classified, endpoints can be authorized to the network and granted access based on their profile. Another example is to provide differentiated network access to users based on the device used. For example, employees can get full access when accessing the network from their corporate workstation but be granted limited network access when accessing the network from their personal iPhone. The configuration process begins with the enablement of specific probes on an ISE appliance running the Policy Service persona.

There are different probes that are responsible for collecting different types of endpoint attributes. These attributes are matched to conditions which can then match rules across a library of device types, or profiles. Based on a generic weighting scale, each matching condition can be assigned a different weight, or certainty factor CF that expresses the relative value that the condition contributes to classification of the device to a specific profile.

Although conditions may match in multiple profiles, the profile for which the endpoint has the highest cumulative CF, or Total Certainty Factor TCF is the one assigned to the endpoint. Once profiled, the endpoint policy can be directly referenced in Authorization Policy Rule conditions.

Unlike earlier ISE v1. In fact, this method is discouraged since the Identity Group attribute is limited to a single value and may be required for other purposes. When possible, it is preferred to leverage the Endpoint Policy attribute or Logical Profile attribute. A Logical Profile is an ad-hoc assignment of specific profile polices to a logical group to simplify policy rules and visibility filters.

Both types of profiles can be created, modified, or deleted to suit the particular deployment. Like Endpoint Profiles, Logical Profiles can be directly referenced in Authorization Policy Rule conditions and can drastically reduce the number of individual rule conditions needed to match many different device types with a common purpose or business function.

In this example, it was not necessary to match each and every type of vendor phone and model, but simply assign the individual profiles to the logical group and apply policy to the group.

Changes can also occur as a result of updates to the Profiling Policy. In other cases, an administrator may want to make a deliberate action to bypass the default policy in the form of an Exception Action.Cisco ISE is a leading, identity-based network access control and policy enforcement system.

It is a common policy engine for controlling, endpoint access and network device administration for enterprises. ISE allows an administrator to centrally control access policies for wired, wireless, and VPN endpoints in a network. This guide is intended to provide technical guidance to design, deploy and operate Cisco Identity Services Engine ISE for posture assessment. The first half of the document focuses on the planning and design activities, the other half covers specifics of configurations and operations.

There are four major sections in this document. The initial, define part talks about defining the problem area, planning for deployment, and other considerations. Next, in the design section, you will see how to design for posture assessment.

Third, in the deploy part, the various configuration and best practice guidance will be provided. Lastly, in the operate section, you will learn how to manage a posture deployment with Cisco ISE.

Before you begin, be sure you have the correct licensing required for posture assessment by reviewing the ISE Ordering Guide. You will also want to ensure you have any required external resource such as Active Directory configured and operating properly. Following the below posture configuration flow will ensure that each required section to configuring ISE for posture assessment will be addressed.

Posture conditions are the set of rules in our security policy that define a compliant endpoint. Some of the these items include the installation of a firewall, anti-virus software, anti-malware, hotfixes, disk encryption and more.

Once posture conditions are defined, posture remediations if required can be configured. Posture remediations are the methods AnyConnect will handle endpoints that are out of compliance.

Some remediations can be automatically resolved through AnyConnect while other might be resolved manually by the end user. Posture requirements are the immediate actions steps taken by AnyConnect when an endpoint is out of compliance.

An endpoint is deemed compliant if it satisfies all the posture conditions. Once configured, posture requirements can then be reference by posture policy for compliance enforcement.

Client provisioning is the policy used to determine the version of AnyConnect used as well as the compliance module that will be installed on the endpoint during the provisioning process. The compliance module is a library that the posture agent uses to determine if the endpoint is in compliance with defined posture conditions.

Lastly, access policy will enable our posture policy and define what form of policy the endpoint will be subjected to if it is compliant, non-compliant or requires provisioning of AnyConnect. Now that we understand the configuration flow, we need to review our deployment options. Most critical is defining security policy. Without a predefined security policy, we will not be able to configure ISE posture to protect our endpoints and network.

While ISE contains a number options for checking endpoint compliance, this guide will use the following security policy example for Windows 10 endpoints:. Depending on your security policy, you will want to select the correct agent for your deployment. Since this guide will use ISE 2. Mainly, there are three types of agent that can be used. Each one has its advantages and disadvantages in term of posture options.

The temporal agent is relatively new to ISE and is designed to be dissolvable. That means no permanent software will be installed on the endpoint. The ability to not force software installation on the endpoints is a clear advantage for the temporal agent.

Ideally, you can use the temporal agent on guest or contractor endpoints. The disadvantage of using the temporal agent is that it is limited in the number of posture conditions it currently supports. Use it for only the most basic of posture checks. The Stealth AnyConnect posture agent is also relatively new and is design to be a permanent installation on the endpoint but in a "headless" configuration.

The advantages of the Stealth AnyConnect posture agent is that it supports basically all the posture conditions as the AnyConnect agent however it will run as a background process to the end-user.This defines 1 or multiple hosts on the switchport.

Only the first device needs authentication. Ports are authenticated first before any other traffic can pass. The windows client configuration can be pushed by a GPO. Configuration of this GPO is out of scope for this blog. Enter the requested information: Repeat this step for all devices with ports which need authentication.

Next, select All Device Types and click Add. Like: Routers — or Routers — Associate a radius client to a location and device type. Select the correct Location and Device Type. Configure a router for using radius:. In the ISE console you can see the user denied logging.

Click Operations — Authenications. Enabling authentication on clients First, make sure the correct protocols are selected. Click Policy — Policy elements — Results — Authentication — Allowed protocol — default network access or create a new one. Make sure the correct sequence is used. Click Policy — Authentication. For periodic reauthentication of the switchports every sec is defaultconfigure:. Click Settings, ensure that Validate Server Certificate is checked. Also make sure that the client does have the root certificate of your CA.

Select this root certificate. Check the switchport authentication:. Check the reauthentication checkbox! Make sure there is an Active Directory group available with the needed computer accounts. Click Add — select groups from directory and add the group. Click Policy — Authorization, click the down arrow at a rule, click Insert new rule above. Click Create new condition Advanced option Fill in the Expression and correct user group. Click the created Dot1x authorization policy.

Next week part 6 of this blog post series: Policy enforcement and MAB. Nobody should be able to use credential danimax again while user A is still active on the network. Afaik their are no options for this in AD. Great guides! I have a quick question on re-authentication if you dont mind? Great question! Reauthentication is not needed for clients, but recommended in some cases. For some reason, the machine certificate gets revoked. If reauthentication is enabled the laptop has to reauthenicate again, but it will fail because of the revoked certificate and the switchport will stop forwarding user traffic.

Introduction

Many thanks!!!This section lists the high-level installation steps to help you quickly install Cisco ISE:. Ensure that you have met the System Requirements as specified in this book. Optional; required only if you are installing Cisco ISE on virtual machines Ensure that you have created the virtual machine correctly. See the following topics for more information:. Configure a VMware Server. See the following documents for more information.

Cisco SNS appliance—install the hardware appliance. Connect to CIMC for server management. Virtual Machine—ensure that your VM is configured correct. You must already have valid Cisco. The Cisco ISE image comes with a day evaluation license already installed, so you can begin testing all Cisco ISE services when the installation and initial configuration is complete. If the SNS appliances are placed in a remote location for example, data centersto which you do not have any physical access and need to perform CIMC install from remote servers, it might take long hours for installation.

We recommend that you copy the ISO file on a USB drive and use that in the remote location to speed up the installation process. A screen similar to the following one appears. The following message and installation menu are displayed. The following message appears. At the prompt, type setup to start the Setup program. See Run the Setup Program for details about the Setup program parameters.

After you enter the network configuration parameters in the Setup mode, the appliance automatically reboots, and returns to the shell prompt mode. Continue with Verify the Installation Process.

This section describes the setup process to configure the ISE server. The setup program launches an interactive command-line interface CLI that prompts you for the required parameters.

An administrator can use the console or a dumb terminal to configure the initial network settings and provide the initial administrator credentials for the ISE server using the setup program. This setup process is a one-time configuration task.

Consult with the staff in your organization responsible for AD and retrieve the relevant IP and subnet addresses for your ISE nodes prior to installation and configuration. It is not recommended to attempt offline installation of Cisco ISE as this can lead to system instability. When you run the Cisco ISE installation script offline, the following error is shown:. Sync with NTP server failed' Incorrect time could render the system unusable until it is re-installed. Choose Yes to continue with the installation.

Choose No to retry syncing with the NTP server. It is recommended to establish network connectivity with both the NTP server and the DNS server while running the installation script.

At the login prompt, enter setup and press Enter. The console displays a set of parameters. You must enter the parameter values as described in the table that follows. Must not exceed 19 characters. Valid characters include alphanumerical A—Z, a—z, 0—9and the hyphen. The first character must be a letter.With v1. Will it be added to v2. The similarities between the two protocols are many. Both are are authentication protocols with the purpose of validating user identity authenticationgiving differentiated access authorisation and logging access accounting.

However, there are also large differences between the protocols which can be read here. Historically most AAA implementations uses Radius for end user access, remote access to networks and But, command authorization is rarely implemented. Below are the configuration changes I have made to a switch in production environment. I have removed all non-relevant configuration. The goal with the configuration is to authenticate access using Radius and having a local authentication as a fallback.

This means that if the ISE is non-responsive it is possible to login with the locally created user after a short timeout. It states that if not configured elsewhere no login is being uses. Practically this allow us to access the device from console no matter what. Below are the steps to configure Cisco ISE. The screen dumps below are from a newly installed fresh ISE config. In case of an in-production ISE please make sure that your changes does not impact existing functionality!

First step is to configure Radius. We define a new device, gives it a name, enter its ip address and the same radius key that is defined in the device See above. Next step is to create a device group.

The purpose is to give all device that will use this configuration a specific attribute to use in the policy created later. We create a new device group and adds our switch to the group.

Now is the time to create the authentication policy.

This is the first step in the login authentication process and the authentication policies differentiates different login sequences. Now we have configured everything that has to do with the authentication process. Next step is to configure authorization. Now we create an authorization policy putting it all together. We also need to create the two different user groups and 2 users, on member of each group.

Connected to User Access Verification. Finally, how does this look like in the ISE logs? The same goes for the other users login.

Let's Install ISE

Unfortunately not in the screen dump below, though. Also, since we enabled radius accounting for exec on start-stop, an accounting packet is sent to ISE on every successfull login and logout of the switch CLI. In the example above, even if the RestrictedCLIUser1 gets privilege level 7, there are no command available on that level. The drawbacks with this are obvious:. Good article Jimmy. How do I choose users from an external identity source? Your email address will not be published.

So, what CAN we do with Radius based device administration authentication?
