Lab Exercise 1: Configure the My Devices

Portal on ISE

Exercise Description

This lab covers the ISE configuration requirements to enable and customize the My Devices Portal. The My Devices Portal allows employees to manage the devices that they themselves have on-boarded to the corporate network. Employees can add devices directly in this portal. Employees can mark any device in their own lists as lost, which prevents others from

unauthorized network access when using the stolen device. Employees can reinstate a blacklisted device in the My Devices Portal to grant it network access without re-registration. Employees can also take any of their devices off the list temporarily, and later register them back for network access.

Exercise Objective

In this exercise, your goal is to familiarize with and configure the My Devices Portal on ISE. This includes completion of the following tasks:

 Verify My Devices Portal enablement

 Customize the My Devices Portal

 Modify the My Devices Portal authentication to include AD for user authentication

 Launch the My Devices Portal and access it using AD user credentials Step 4 Access the ISE administrative web interface.

a. On Admin PC, launch Mozilla Firefox web browser. Enter this URL in the address bar: https://ise-1.demo.local/

Note: Accept/Confirm any browser certificate warnings if present. Note: “Your browser is not supported” may be ignored.

Lab Exercise 2: Configure ISE for Single SSID

Wireless BYOD configuration

Exercise Description

This exercise will show how to configure ISE for BYOD wireless deployment where only one wireless SSID is required. Firstly you will confirm SSID settings on the Cisco WLC. Next you will learn how to configure profiles for the SCEP CA and the Certificate Authentication Profile. Cisco ISE uses Simple Certificate Enrollment Protocol (SCEP) to support the secure issuance of certificates to network devices in a scalable manner. The SCEP in this lab is Microsoft Network Device Enrollment Service on Windows Server 2008 R2 Enterprise. You will also learn how to configure a client provisioning policy on Cisco ISE to allow the native supplicant provisioning.

Exercise Objective

In this exercise, your goal is to configure ISE for single SSID Wireless BYOD, which includes the completion of the following tasks in ISE:

 Familiarize the WLC configuration needed for single SSID

 Verify the Network Access Device configuration of the WLC

 Configure the SCEP CA Profiles and the Certificate Authentication Profile

 Modify the Identity Source Sequence to authenticate the user against AD

 Modify the Authentication Policy to accept 802.1X authentication from wireless access devices with EAP-TLS or PEAP (EAP-MSCHAPv2) protocols.

 Modify the Authorization Policy to allow registration as well as supplicant provisioning and to grant full access to registered devices.

 Create Client Provisioning Policy to support native supplicant provisioning Step 1 Open a new tab on the web browser and access the ISE administration web interface at

Lab Exercise 3: Test and Verify the onboarding

of a non-corporate Apple iPad

Exercise Description

In this exercise you will get the experience of onboarding an Apple iPad onto the network in a BYOD use case. From the iPad you will connect over the wireless network to the single SSID you configured in the earlier exercise. You will use your AD credentials to let Cisco ISE know that the iPad is a personal device that belongs to you the employee. When you connect to the network you will verify profile installation for the native supplicant on the iPad. Using Cisco ISE live logs you will monitor the onboarding process and verify successful completion via the My Devices Portal.

Warning: The Apple iPad you will be using is controlled remotely using VNC over the USB port of the admin PC. Due to configuration and limitations of remotely controlling an interactive device like the iPad in a lab environment please do not deviate from the exercise steps. Any deviation may result in losing connectivity to the iPad, which will need physical / manual resetting and prevent you from experiencing the full potential of the lab.

Thank you for your cooperation.

Exercise Objective

In this exercise, your goal is to complete the following tasks:

 Connect to the iPad via VNC to test the wireless BYOD feature

 Connect the iPad to the corporate SSID and check the onboarding of Apple iPad and installation of the profiles for the native supplicant for the corporate user

 Check the ISE Live Logs to monitor the process

 Check the My Devices Portal to see the device registration

Step 1 Click on the short-cut VNC-to-iPad on the taskbar to start a VNC session to the iPad. Step 2 Press any key to continue, once prompted to do so.

Tips on controlling the iPad UI via VNC client:

Home: (On PC/Mac with 2/3-button mouse) Right click once with a mouse. (On Mac with track pad) Touch with two fingers on the Track Pad If Secondary Click is configured.

Mouse: Mouse pointer mimics touching the iPad screen with one finger.

Scrolling or dragging: Press and hold Left mouse button and move the mouse pointer to scroll

Keyboard: Move the pointer over any text box on the iPad, click once, and then begin using your local keyboard for input. Note: The tab key is not available on the iPad’s virtual keyboard so you will have to move the pointer to the text field you want to input text, and click on it.

Step 3 On the iPad, navigate to Settings > General > Profiles. Remove any existing profiles, if present.

Note: If no profiles, you might not see the profiles menu option.

Step 4 Next on the iPad, go to Settings > Safari and hit Clear History as well as Clear Cookies and Data.

Step 5 Go to Settings > Wi-Fi and slide the virtual switch to enable Wi-Fi. Select and connect to the network n-p##-TS-WPA2e

(21)

Note: This certificate with a subject name aaa.demo.local shown as the certificate subject, it is a wild-card certificate.

Note: Apple iOS prompts for the RADIUS server EAP-TLS certificate because it sees the certificate the first time and an ad-hoc connection.

c. Next click on the blue arrow of the connected network and verify the IP address assigned

Note: IP address for the iPad might be different depending on the DHCP scopes defined for the POD. Your iPad might get an IP address from 10.1.10.x subnet which is OK.

Step 6 Now launch the mobile Safari app and access the website www-int.demo.local.

You will receive a warning “Cannot Verify Server Identity”. Click Continue then be redirected to the self-provisioning page.

Note: If a red error shown and the Register button is grey out, check if a Client Provisioning Policy rule has been created for the Apple iOS (Policy > Client Provisioning).

Also, run a Supplicant Provisioning Report (Operations > Reports > Endpoints and Users > Supplicant Provisioning > Run)

Lab Exercise 4: Test and Verify the Device

Blacklisting function on My Devices Portal

Exercise Description

This exercise will show you the device self-management features of Cisco ISE. You will simulate losing your iPad and blacklisting the device as lost. Blacklisting the device

prevents it from being misused on the corporate network. Cisco ISE uses RADIUS CoA messaging to interact with network access devices in enforcing restrictions on the user self-provisioned device.

Exercise Objective

 Customize the Authorization Profile to Blacklist wireless endpoints

 From the My Devices Portal mark the device as Lost to observe the Change of Authorization (CoA) occur and restrict access from the device

 When the device is reinstated on the My Devices Portal, Change of Authorization is again triggered and the device should now be given a full network access

Step 1 Refer to Appendix A for the sample WLC configuration. Login to WLC web interface

Lab Exercise 5: Configure ISE for 3rd Party

MDM integration

Exercise Description

This lab covers the ISE configuration requirements to enable ISE integration with 3rd Party MDM servers. Mobile Device Management (MDM) software secures monitors, manages and supports mobile devices deployed across mobile operators, service providers and enterprises. A typical MDM product consists of a policy server and an inline enforcement point that controls the use of applications (e.g. email) on a mobile device in the deployed environment. Today Cisco Identity Services Engine (ISE) is the only entity that can provide granular access to endpoints (based on ACL’s, trust sec SGT’s etc.). In this integration, ISE-enabled network is the enforcement point while the MDM policy server serves as the policy decision point. ISE expects specific data from MDM servers to provide a complete solution

The following are the high-level use cases in this solution.

 Device registration- Non registered endpoints accessing the network on-premises will be redirected to registration page on MDM server for registration based on user role, device type, etc.

 Remediation-Non compliant endpoints will be given restricted access based on compliance state

 Periodic compliance check – Periodically check with MDM server for compliance

 Ability for administrator in ISE to issue remote actions on the device through the MDM server (e.g.: remote wiping of the managed device)

 Ability for end user to leverage the ISE My Devices Portal to manage personal devices, e.g. Full Wipe, Corporate Wipe and PIN Lock.

MDM Servers can be used as a cloud service or installed locally on premises. Once the installation, basic setup and compliance checks are configured on the MDM server, it can then be added to ISE

(27)

MDM Integration use-case overview

1. User associates device to SSID

2. If user device is not registered, user goes through the BYOD on-boarding flow, details listed in Appendix

3. ISE makes an API call to MDM server

4. This API call returns list of devices for this user and the posture status for the devices – Please note that we can pass MAC address of endpoint device as input parameter.

5. If user’s device is not in this list, it means device is not registered. ISE will send a change of authorization to NAD to redirect to ISE, Users will be re-directed to MDM server (home page or landing page)

6. ISE will know that this device needs to be provisioned using MDM and will present an appropriate page to user to proceed to registration.

7. User will be transferred to the MDM where registration will be done. Control will transfer back to ISE either through automatic redirection by MDM server or by user refreshing their browser again. 8. ISE will query MDM again to gain knowledge of Posture status

9. If the user device is not in compliant to the posture (compliance) policies configured on MDM, they will be notified that the device is out of compliance and need to be in compliance

10. Once user’s device becomes compliant, MDM server will update the device state in its internal tables. 11. At this stage user can refresh the browser at which point control would transfer back to ISE.

12. ISE would also poll the MDM server periodically to get compliance information and issue COA’s appropriately.

Exercise Objective

In this exercise student will add 3rd party MDM server in to ISE and then configure ISE authorization polices to use MDM attributes.

Note: Certificate for the 3rd party MDM server for step 1 is already downloaded into ISE. Step 1 is only to view the Certificate for the completeness of the configuration.

Go to Administration

>

System

>

Certificates

>

Certificate Store and verify that the Mobile Iron Certificate is in Certificate Store as shown below.

Step 2 Add MDM Server, Go to Administration > Network Resources > MDM. Click Add, to add the MDM server. Enter MDM Server details as below with credentials User name: admin

Password:

ISEisC00L

(29)

Step 3

Click on “Test Connection” and an info dialog box will

pop up.

Step 4 Click on Submit. It will test the connectivity again and add the MDM server. Also, check the MDM status and ensure it is Active.

Step 5 Review the MDM dictionaries. Once the MDM server is added, the supported dictionaries show-up on ISE, which could be later used in to ISE Authorization Policies. Go to Policy > Policy Elements > Dictionaries > System > MDM > Dictionary Attributes and review all the available attributes.

(30)

ISE_1.2_BYOD_Lab_Guide_2014-04-18 4/20/2014 9:59:00 PM Page 30 of The Cisco Identity Services Engine IP address = 10.1.100.21

Internal Corporate Networks = 10.0.0.0, 255.0.0.0 (to redirect) (Allow ISE and MDM Server) MDM Server = 10.1.100.15

Explanation of the MDM_Quarantine_ACL is as follows 1. Allow DNS traffic “inbound” for name resolution.

2. Allow all traffic “inbound” to ISE for Web Portal and supplicant and Certificate provisioning flows 3. Allow access “inbound” to MDM server for MDM device registration and compliance checks 4. Allow ICMP traffic for trouble shooting, it is optional

5. Deny all traffic “inbound” to corporate resources. Any 80/tcp access hits will redirect to ISE (As per company policy) 6. Permit all the rest of traffic, to allow remediation from Internet sites, such as Apple app store.

Step 7 Configure ISE Authorization Policies. Once MDM server is added in to ISE, we can configure authorization polices in ISE to leverage the new dictionaries added for MDM servers.

a. Create an Authorization Profile named “MDM_Quarantine” for devices which are not in compliant to MDM polices. In this case all non-compliant devices will be redirected to ISE and presented with a message

(31)

Step 8 Update ISE Authorization Policy a. Go to Policy > Authorization.

b.

Locate the Authorization policy rule Reg with ISE TLS and select Duplicate Above

c. Update the two policy rules (Reg with ISE TLS and its duplicate) as defined below, in turn: Reg with ISE and MDM comp - Once the device is registered with both ISE and MDM, and is in compliance to MDM policies, it will be granted full access to the network.

Reg with ISE NOT MDM - This Authorization Rule is added for devices which are registered with ISE but either not yet with an MDM server or not in compliant to MDM policies. Once the device hits this rule, it will be forwarded to ISE MDM landing page. If not yet registered with MDM, the “Register” button is shown. If already registered but not yet compliant, it will inform the user about the compliance failure. Note: Use Duplicate Above/Below to speed up creating rules with similar conditions.

party MDM

integration onboarding of a non-corporate

Apple iPad

Exercise Description

In this exercise you will get the experience of MDM enrollment process, BYOD on-boarding on the iPad was already completed in Lab Exercise 3 therefore this will be followed by MDM enrollment. iPad’s native supplicant is already provisioned with the wireless SSID therefore this will address the MDM enrollment. Using Cisco ISE live logs you will monitor the onboarding process and verify successful completion via the My Devices Portal.

Warning:

The Apple iPad you will be using is controlled remotely using VNC over the USB port of the admin PC. Due to configuration and limitations of remotely controlling an interactive device like the iPad in a lab environment please do not deviate from the exercise steps. Any deviation may result in losing connectivity to the iPad, which will need physical / manual resetting and prevent you from experiencing the full potential of the lab.

Thank you for your cooperation.

Exercise Objective

 Complete device enrollment with 3rd party MDM, install corporate application

 Check the ISE Live Logs to monitor the process

 Check the My Devices Portal to see the device registration

 Use My Devices Portal to issue a corporate wipe.

Step 1 On iPad, go to Settings > Wi-Fi and slide the virtual switch to turn on Wi-Fi.

Note-1: If the VNC to iPad is closed then, click on the short-cut VNC-to-iPad on the taskbar to restart a VNC session to the iPad. Note-2: If the Wi-Fi is not turned off at the end of Lab Exercise 4, first turn it off and remove the client session from the wlc -- Use the Firefox browser on the admin-PC to go to https://wlc.demo.local, navigate to menu MONITOR > Clients, follow the client mac address hyperlink to drill into the session, and click the button “Remove”.

Step 2 Launch the mobile Safari app and access www.google.com. The endpoint will have access as per corporate policies, as the iPad was previously registered with ISE in Lab Exercise 3. Step 3 Now access the website www-int.demo.local (Corporate Resource), since the device is not

If the iPad does not prompt for “App Installation” please check with the Lab Administrator. This is to test non-compliance state of the iPad.

iPad is now registered with the MobileIron MDM server but is missing the corporate application therefore is NOT compliant with ISE as per configured Policies.

Step 5 As part of corporate compliance polices, the device needs to have the corporate applications. In this LAB, MDM server will be pushing the Calculator for iPad Free application onto the iPad.

Notes: At this time Click Cancel for “Calculator for iPad Free”.

Step 6 As part of corporate compliance polices, the device needs to have the corporate applications. In this LAB, MDM server will be pushing the Quick Graph: Your Scientific Graphing Calculator application onto the iPad.

Notes: At this time Click Install for Quick Graph: Your Scientific Graphing Calculator.

Enter Password = ISEisC00L when prompted

Please allow time for APP installation to complete

Step 7 Click on Safari to open the browser and access “www-int.demo.local” then click the Continue button so ISE can send a COA-Reauth.

(39)

Step 8 Type the original URL in the address bar “www-int.demo.local”. iPad is non-compliant with the corporate polices as it’s missing the Calculator for iPad Free application therefore ISE will redirect the user to the MDM non-compliance page.

The explanation and recommendation text might be different from the screenshot, depending on the MobileIron VSP server version.

Step 9 Go to iPad home screen by right click on iPad, Hold Down the click Key and move the mouse towards your left to Swipe on Screen, this will take you to a new page on iPad, click on the MobileIron Agent to launch the application.

Note: If the page has no MobileIron, right click once to go back to iPad home screen and right click again to launch search. Enter MobileIron as the search string to find and launch it.

Step 10 Re-Enroll with MDM

Lab Exercise 8: Test and Verify the Corporate

Wipe function on My Devices Portal

Exercise Description

This exercise will show you the device self-management features of Cisco ISE. You will simulate losing your iPad and performing a Corporate Wipe action on the device.

Corporate Wipe will remove all the corporate data. In this case Quick Graph: Your Scientific Graphing Calculator & Calculator for iPad Free applications were pushed as a corporate application earlier so will be removed. Cisco ISE uses API’s to interact with the MDM Server in enforcing restrictions on the user self-provisioned device.

Exercise Objective

 Review the MDM_Quarantine policy that was created earlier

 From the My Devices Portal initiate the Corporate Wipe action on the device to observe the Change of Authorization (CoA) occur and restrict access from the device

Step 1 Refer to Appendix A for the sample WLC configuration. Login to WLC web interface
