iOS Device

Let's take a look at the tasks that Tom, the EMM administrator of MobX, has to do from downloading WSO2 EMM to registering the iOS device of Kim, the device owner.

Configuring WSO2 EMM

Tom needs to configure the following to allow users to register and monitor their devices with WSO2 EMM:

• Configuring the email client

• Enabling WSO2 API Manager communication

• Specifying the WSO2 EMM server

Configuring the email client

Configure the email client to send out registration confirmation emails to users through WSO2 EMM:

1. Create an email account (e.g., tom-mobx@gmail.com) to send out emails to users who register with WSO2 EMM.

   If you are using a Google mail account, note that Google treats WSO2 EMM as a third-party application and restricts it from sending emails by default. Disable this restriction before sending emails to confirm user registrations or invite users.

    Expand this to enable Google to provide access to third-party applications...

   1. Navigate to https://myaccount.google.com/security.
   2. Click Signing in to Google on the left menu and make sure that the 2-Step Verification is disabled or off.
      
   3. Click Connected apps and sites on the left menu and enable Allow less secure apps.
      

2. Open the <EMM_HOME>/repository/conf/axis2/axis2.xml file, uncomment the mailto transportSender section, and configure the EMM email account.
   Before the configuration:

   <!-- Uncomment and configure the SMTP server information check com.sun.mail.smtp package documentation for descriptions of properties
       <transportSender name="mailto" class="org.apache.axis2.transport.mail.MailTransportSender">
           <parameter name="mail.smtp.host">smtp.gmail.com</parameter>
           <parameter name="mail.smtp.port">587</parameter>
           <parameter name="mail.smtp.starttls.enable">true</parameter>
           <parameter name="mail.smtp.auth">true</parameter>
           <parameter name="mail.smtp.user">synapse.demo.0</parameter>
           <parameter name="mail.smtp.password">mailpassword</parameter>
           <parameter name="mail.smtp.from">synapse.demo.0@gmail.com</parameter>
       </transportSender>
   -->

   Tip: For mail.smtp.from, mail.smtp.user, and mail.smtp.password, use the email address, username, and password (respectively) from the mail account you set up.

   Example, after the configuration:

   <transportSender name="mailto" class="org.apache.axis2.transport.mail.MailTransportSender">
      <parameter name="mail.smtp.host">smtp.gmail.com</parameter>
      <parameter name="mail.smtp.port">587</parameter>
      <parameter name="mail.smtp.starttls.enable">true</parameter>
      <parameter name="mail.smtp.auth">true</parameter>
      <parameter name="mail.smtp.user">tom-mobx</parameter>
      <parameter name="mail.smtp.password">$mobx1234</parameter>
      <parameter name="mail.smtp.from">tom-mobx@gmail.com</parameter>
   </transportSender>

Enabling WSO2 API Manager communication

Configure the following fields, which are under the <APIKeyValidator> tag in the <EMM_HOME>/repository/conf/api-manager.xml file.

1. Configure the <serverURL> field by replacing ${carbon.local.ip} with the hostname or public IP. For example:

   <ServerURL>https://10.10.10.253:${mgt.transport.https.port}${carbon.context}/services/</ServerURL>

2. Configure the <RevokeAPIURL> field by replacing ${carbon.local.ip} with the hostname or the public IP. For example:

   <RevokeAPIURL>https://10.10.10.253:${https.nio.port}/revoke</RevokeAPIURL>

3. Restart the WSO2 EMM server. 

Specifying the WSO2 EMM server

WSO2 EMM uses a web agent to enroll devices. Tom follows the steps below to configure the agent and the device management app to communicate with the correct WSO2 EMM server:

1. Open the <EMM_HOME>/repository/deployment/server/jaggeryapps/ emm-web-agent/app/conf/config.json file and give the entire server address in the host attribute that is under generalConfig. This file configures the web agent to handle device enrollments. For example:

   "generalConfig" : {
           "host" : "http://10.10.10.253:9763",
           "companyName" : "WSO2 Enterprise Mobility Manager",
           "browserTitle" : "WSO2 EMM",
           "copyrightText" : "\u00A9 %date-year%, WSO2 Inc. (http://www.wso2.org) All Rights Reserved."
   }

2. Open the <EMM_HOME>/repository/deployment/server/jaggeryapps/emm/app/conf/config.json  file and give the entire server address in the host attribute that is under generalConfig. This file configures WSO2 EMM to manage devices. For example:

   "generalConfig" : {
           "host" : "10.10.10.253:9443",
           "companyName" : "WSO2 Carbon Device Manager",
           "browserTitle" : "WSO2 Device Manager",
           "copyrightPrefix" : "\u00A9 %date-year%, ",
           "copyrightOwner" : "WSO2 Inc.",
           "copyrightOwnersSite" : "http://www.wso2.org",
           "copyrightSuffix" : " All Rights Reserved."
   }Please note that because you did not install the WSO2 EMM iOS agent while registering the device

Configuring iOS support in EMM

Now that we have configured EMM, we are ready to set up iOS support as described in the following sections.

• Installing the iOS features
• Configuring WSO2 EMM for iOS
• Generating an MDM APNS certificate
• iOS platform configurations

Installing the iOS features

After obtaining a signed CSR, the P2 repository, and the other files via email, Tom proceeds to install the specific features in the P2 repository that are required to enable iOS.

1. Go to the WSO2 EMM Management Console at https://<EMM_HOST>:<EMM_PORT>/carbon and log in using admin/admin as the credentials.

   1. The <EMM_PORT> is set to 9443 for HTTPS and 9763 for HTTP by default. As you access the EMM Management Console over HTTPS, use 9443 in the URL.

   2. When the pages appear, the web browser typically displays an "insecure connection" message, which requires your confirmation before you can continue.

       Click here for more information.

      The EMM Management Console is based on the HTTPS protocol, which is a combination of HTTP and SSL protocols. This protocol is generally used to encrypt traffic from the client to server for security reasons. The certificate that it works with is used for encryption only and does not prove the server identity. Therefore, when you try to access the Management Console, you usually get a warning saying that the connection is untrusted. To continue working with this certificate, accept the certificate before accessing the site. If you are using the Mozilla Firefox browser, you have to accept the certificate only at the first time. After that, the certificate gets stored in the browser database and marked as trusted. However, with other browsers, the insecure connection warning might be displayed every time you access the server.

      This scenario is suitable for testing purposes, or for running the program on the company's internal networks. If you want to make the Management Console available to external users, you must obtain a certificate signed by a well-known certificate authority, which verifies that the server actually has the name it is accessed by and that the server belongs to the given organization.

2. Click Features on the Configure tab.
   
3. Click Add Repository on the Repository Management tab to add the repository to the server.
   

4. Fill out the form and click Add. If the Local option is selected for location, unzip the p2-repo.zip file that you received via email when obtaining the CSR file and give the path to that directory.
   

5. Click the Available Features tab, select the respective repository, and click Find Features. If the Group features by category option is selected by default, deselect it before checking for the available features. 
   

6. Select the EMM - iOS Device Management feature and click Install.
   
7. Click Next, accept the license agreement, and click Next to install the features.

8. Once the features are successfully installed, you will be prompted to restart now or later. 

   Don't click restart now until you have completed step 9 and 10.

9. Enter the IP or the domain name for the following parameters in the <EMM_HOME>/repository/conf/ios-config .xml  file.
   
   • iOSEnrollURL
   • iOSProfileURL
   • iOSCheckinURL
   • iOSServerURL TokenURL

   For example:

   <?xml version="1.0" encoding="ISO-8859-1"?>
   <iOSEMMConfigurations>
       <!-- iOS MDM endpoint urls -->
       <iOSEnrollURL>https://10.10.10.193:9443/ios-enrollment/scep</iOSEnrollURL>
       <iOSProfileURL>https://10.10.10.193:9443/ios-enrollment/profile</iOSProfileURL>
       <iOSCheckinURL>https://10.10.10.193:9443/ios-enrollment/checkin</iOSCheckinURL>
       <iOSServerURL>https://10.10.10.193:9443/ios-enrollment/server</iOSServerURL>
   </iOSEMMConfigurations 

10. Open <EMM_HOME>/repository/conf/cdm-config.xml and uncomment the APNSBasedPushNotificationProvider that is under PushNotificationProviders. For example:

    <PushNotificationProviders>
        <Provider>org.wso2.carbon.device.mgt.extensions.push.notification.provider.gcm.GCMBasedPushNotificationProvider</Provider>
        <Provider>org.wso2.carbon.device.mgt.mobile.impl.ios.apns.APNSBasedPushNotificationProvider</Provider>
    	<!--<Provider>org.wso2.carbon.device.mgt.extensions.push.notification.provider.mqtt.MQTTBasedPushNotificationProvider</Provider>-->
    	<!--<Provider>org.wso2.carbon.device.mgt.extensions.push.notification.provider.xmpp.XMPPBasedPushNotificationProvider</Provider>-->
    </PushNotificationProviders>

11. Go back to the EMM Management Console and click Restart Now.

Tom has now installed the features required to enable iOS. Next, Tom proceeds to configure WSO2 EMM for iOS.

Configuring WSO2 EMM for iOS

Configuring WSO2 EMM for iOS in a production environment involves many steps. To make the testing process easy, Tom has written a script that automates most of the steps. Let's take a look at how it works and configure the server settings.

1. Download the ios-configurations.zip  file and unzip it to the <EMM_PRODUCT_HOME> directory.

2. Run the script you just downloaded to configure the iOS server settings in WSO2 EMM.

   cd <EMM_PRODUCT_HOME>/ios-configurator
   ./ios.sh

3. Enter the requested information when prompted. Be sure to provide the same information you gave when generating the CSR file. For example:

   

Next, Tom generates an MDM Apple Push Notification Service (APNS) certificate. 

Generating an MDM APNS certificate

Except for a few operations (ring, message and get location) that are performed by the WSO2 EMM agent, all the other device operations, and policies are applied on an iOS device via it's operating system. Therefore, for the WSO2 EMM server to communicate with the operating system of the device, you need to generate the MDM APNS certificate.

The MDM APNS certificate will be referred to as the MDM certificate in the EMM Console.

1. Go to https://appleid.apple.com/account#!&page=create and get an Apple ID, if you do not have one already. 
2. Go to the Apple Push Certificate Portal at https://identity.apple.com/pushcert/ and log in with your customer account details. You do not need an enterprise account for this. Your Apple ID is sufficient.
3. Click Create Certificate and agree to the terms and conditions.
4. Upload the encoded .plist file you received via email from WSO2 earlier in this guide.

5. Download the generated MDM signing certificate, which is a certificate for third-party servers provided by Apple, and rename it to MDM_Certificate.pem.

6. Get the USERID (TOPIC ID) from the MDM signing certificate (MDM_Certificate.pem), as it will be used later in the configuration. 
   You can decode the MDM signing certificate to obtain the USERID by executing the following command:

   openssl x509 -in MDM_Certificate.pem -text -noout

7. Remove the password/pass phrase from your private key file (e.g.,customerPrivateKey.pem).

   openssl rsa -in customerPrivateKey.pem -out customerKey.pem 

8. Merge the customer key file that was derived in the latter step with the MDM signing certificate to generate the MDM Apple Push Notification Service (APNS) Certificate. In this example, Tom merges the customerKey.pem file with the MDM_Certificate.pem file to generate the MDM_APNSCert.pem file.

   Tip: Before you merge the customerKey.pem file and the MDM_Certificate.pem file, make sure both files are in the same directory.

   cat MDM_Certificate.pem customerKey.pem > MDM_APNSCert.pem

9. Open the APNS Certificate (MDM_APNSCert.pem) and add a line break between the content of the two files. For example, if your content looks as "-----END CERTIFICATE----------BEGIN RSA PRIVATE KEY-----", add a line break after 5 dashes so that the content looks as follows:

   -----END CERTIFICATE-----
   -----BEGIN RSA PRIVATE KEY-----

10. Convert the MDM_APNSCert.pem file to MDM_APNSCert.pfx file. You need a password for this, which you will need again when configuring the iOS platform configurations.
    

    openssl pkcs12 -export -out MDM_APNSCert.pfx -inkey customerPrivateKey.pem -in MDM_APNSCert.pem

Configuring the iOS platform

Multiple tenants can use WSO2 EMM while maintaining tenant-based isolation. The iOS platform configurations page enables tenants to customize the iOS settings based on their own requirements.

Tom proceeds to configure the iOS platform configurations by adding the generated MDM APNS certificate.

1. Log in to the EMM Console at https://<EMM_HOST>:<EMM_PORT>/emm  using admin as the username and password if you haven't previously logged in.

2. Click Menu > CONFIGURATION MANAGEMENT > PLATFORM CONFIGURATIONS > iOS Configurations and fill in the form.

   • MDM Certificate Password: Give the same password you gave when converting the MDM_APNS certificate from the pem to the pfx format. 
   • MDM Certificate Topic ID: Give the topic ID of the certificate.

   

   Tip: To learn more about each platform setting, hover your mouse pointer over the help tip.

Configuring WSO2 EMM to install iOS applications

The download URL for WSO2 EMM is configured for HTTP by default. Although you can install Android mobile applications using this default configuration, to install iOS applications, you need to configure it for HTTPS as it's required for the iOS MDM protocol behavior.

Follow the steps given below to configure WSO2 EMM to install iOS mobile applications:

1. Open the <EMM_HOME>/repository/conf/app-manager.xml file.

2. Add %https% as the value for the AppDownloadURLHost property.

   <Config name="AppDownloadURLHost">%https%</Config>

   Tip: To test WSO2 EMM App management features on Android devices, please use one of the following options:

   • Change the value of the AppDownloadURLHost property back to HTTP 
   • Continue using HTTPS to install applications on Android devices by Generating a BKS File for Android.

Creating users and a sample policy

Follow the steps given below to create two users, Kim and Tom, and a configured passcode policy. This will make it easy for you to try out the EMM quick start guide.

1. Download the WSO2 EMM sample pack.

2. Copy the file to a preferred location, navigate to the file via the command prompt, and run the script.

   cd <EMM_QSG_SAMPLE-PACK>
   ./emm-qsg.sh

3. Enter your email address when prompted. 

   Why?

   The device owner Kim will be registered with your email address. Therefore, you will be notified via email on how to register your device with WSO2 EMM while following the EMM quick start guide.

   Example:

   Enter your email address and press enter : kim@wso2.com

Updating the passcode policy

As a security measure, the MobX management has asked Tom to update the passcode policy for all iOS devices so that a device user can only enter the wrong password five times. If a user fails to enter the correct password in the fifth attempt, the device will not be accessible for 15 minutes. This can be regulated in WSO2 EMM by updating the passcode policy that was already in place. Tom follows the steps given below to update the policy:

1. Log out of the EMM console and log in using the following credentials:
   Enter tom as the username and tomemm as the password.

2. Click LOG IN.
3. In the EMM console click View under POLICIES.
   

4. Click the edit logo that is on the passcode policy for iOS devices.

5. Update the passcode profile that is already in place by defining the maximum fail attempts as 5, and click CONTINUE.

   A profile in the context of EMM refers to a collection of policies.

   If you want to know more about each policy setting, hover your mouse pointer over the help tip.

   

6. The passcode policy that was created for this scenario has the following groups assigned. You can optionally update the groups. 
   

   1. Tom had selected the default ownership type ANY for set device ownership type.
      The set device ownership type defines if the policy needs to be applied on BYOD, COPE or both these device types. The ownership types are listed below: 

      Device ownership type	Description
      BYOD	Bring Your Own Device.
      COPE	Corporate-Owned, Personally Enabled.
      Any	The configured profile of policies will be assigned to both the BYOD and COPE device ownership types.

   2. Tom had selected the set user role/s option and then selected the emm-user role from the item list.

   3. Tom had selected Enforce as the action that needs to be carried out when a device has not complied with a policy.  

      The following actions are referred to as non-compliance rules and determine how policies are monitored.

      Non-compliance rules	Description
      Enforce	Forcefully enforce the policies on the assigned groups.
      Warning	If the assigned groups do not adhere to the given policies, a warning message will be sent.
      Monitor	If the assigned groups do not adhere to the given policies, the server is notified of the violation without notifying the user, and the administrator can take the necessary actions.

7. Click CONTINUE.
   Optionally, you can update the name and the description of the policy.

8. It is mandatory that the policy is assigned to Kim's mobile device, so Tom clicks SAVE & PUBLISH to make the policy active immediately.

Publishing applications

Tom needs to publish the WSO2Con application that was created when running the emm-qsg script.

1. Navigate to the App Publisher using the following URL: https://<EMM_HOST>:<EMM_PORT>/publisher

2. Enter the username as tom and password as tomemm. 

   In this scenario, we haven't enabled SSO authentication. Therefore, you need to enter the username and password to log in, else you will automatically be logged in.

   For more information, see Enabling SSO for WSO2 EMM.

3. Click Submit for Review for the WSO2Con application.
   
4. Click Approve > Publish.
   The WSO2Con application is now available in the app store for device owners like Kim to install on their devices.

Monitoring devices

Tom can monitor the devices registered with WSO2 EMM via the device statistics dashboard. 

1. Click the menu icon, and then click DEVICE STATISTICS to access the device statistics dashboard.
   
2. The device statistics dashboard is facilitated via the WSO2 Dashboard Server. Therefore, since you have not enabled SSO in this guide for WSO2 EMM, you will need to log into the dashboard using tom as the username and tomemm as the password.
   Currently, you will not see any data populated in the dashboard as there are no enrolled devices and no non-compliant or unmonitored devices in the system. 

Inviting Kim to register the device with WSO2 EMM

Tom follows the steps given below to invite Kim to register her device with WSO2 EMM:

1. On the dashboard, click View under USERS.
   
2. Click SELECT on the top right corner to select the users you wish to invite.
   
3. Select the user Kim User.
4. Click Invite Selected.

Registering the iOS device

Kim receives the email and accesses the email via her iOS device. To download the EMM agent, Kim clicks on the link sent in the email and then follows the steps given below:

Follow the instructions below to register an iOS device:

1. The Safari browser will display the EMM iOS Enrollment screen. iOS devices need the root certificate to be downloaded to trust the server certificate. Tap Install EMM Certificate.
   
2. The Install Profile screen appears. Tap Install. 
   
3. Tap the Skip Agent Installer link at the bottom of the screen.
   
4. On the EMM Registration screen, enter your details:
   
   • Username - Enter kim as the username.
   • Password - Enter kimemm as the password. 
   • Domain - You don't need to enter the domain details for this scenario.

   By default WSO2 EMM only supports the "bring your own device" (BYOD) registration process for the iOS platform.

5. Tap Log In. 

6. After reading the End User License Agreement (EULA), tap I accept the terms. 

   

7. Tap Install when prompted to install the WSO2 Profile Service. 

   

8. A warning message appears to indicate that by installing the profile the EMM will remotely manage the iOS device. Tap Install.

9. Tap Trust to confirm that you are aware of the device being remotely managed by installing the profile.

   

10. After the profile is installed, click Done.

    

11. Upon the successful registration, the following confirmation appears.

    

Trying out iOS device operations

Kim can now navigate to the Device management page, view information specific to her device, and carry out operations on the device. She follows the steps given below:

1. Access the EMM Management Console using kim as username and kimemm as the password.
2. Click the menu icon.
3. Click DEVICE MANAGEMENT.
4. Click view on the registered device.
   

5. Kim tries out the various operations on her device via the WSO2 EMM Management Console.

   Please note that because we did not install the WSO2 EMM iOS agent while registering the device, the ring device, send notification, and get device location operations do not function. For more information on installing the agent in the registration process, you can follow the steps in End-user Registering an iOS Device.

   For more information on the available features, see Feature Categorization for Supported Device Types.

   

Installing an application on the iOS device

MobX wants Tom to ensure that the employees can only download mobile applications made available via the MobX app store. For this, Tom creates and publishes the WSO2Con application to the MobX app store.

Let's take a look at how Kim installs this application on the device.

1. Navigate to the App Store using the following URL:  https://<EMM_HOST>:<EMM_PORT>/store 
2. Log in using kim and kimemm as the username and password.
3. Click the WSO2Con mobile application, and click Install. 
4. Select Instant install, and click Yes.
   
5. Click on your device in the pop-up menu to install and subscribe to the application.
6. A success message will be shown when you have successfully subscribed to the application.
