Device Registration occurs when Instasafe Secure Access (ISA) automatically captures certain device identification details when an ISA User Agent connects to the ISA Controller.  The information captured during Device Registration are:

1. MAC Address of the physical network adapter
2. Operating System Name
3. BIOS Serial Number
4. Universally Unique Identifier (UUID)

The above information is captured irrespective of whether the User Agent is able to successfully connect to the ISA Controller.

Using these parameters, it is possible to enforce Device Binding on users. Device Binding will ensure that the users are allowed to make connections only from those devices registered in the ISA web console. This will eliminate attacks due to stolen or shared passwords. A user can be bound to multiple devices.

In addition to configuring Device Binding using automatically captured parameters, the ISA web console allows admins to register devices manually.  

This article describes the process of configuring Device Binding using automatic Device Registration. 

1. Log into the ISA web console using admin credentials
2. Navigate to the DEVICES & CHECKS > DEVICES page. 
3. The information of automatically captured devices will be listed here. Each device will be listed with their automatically created name. The name is the concatenation of the username of the remote user, the string “device”, and a number separated by underscores. The number represents the number of devices this user has connected with. For example, the user Ruby has connected with one device, an Ubuntu client. If the same user connects from a Windows client, a new entry will be created and listed with an identical name but the number increased to two. For the purpose of this article, we select the device profile name “ruby_device_1” and bind it to the user Ruby.
4. When a user's device information is captured, the default status of the device is Pending Approval. Until the device is approved or activated, if the user or the user group has Device Binding enabled, the user will not be able to connect from the device. Click the name of the device. For updating the statuses of a large number of devices at once, refer to the KB article Performing Bulk Operation on Device List
5. On the Device Details window, click Activate
6. On the pop-up window, click Yes, Activate it!.
7. The device has been activated.
8. Navigate to the USERS & GROUPS > Users page.
   
9. On this page, click on the name Ruby Kane
10. In the edit user window, click on Edit.
11. Scroll down and toggle the Device Binding button to enable it. Then click inside the Select devices box to list the device names. Select the device name for the user. In this example, ruby_device_1.
12. Click on Update at the bottom to save this configuration. 
13. A message at the bottom, User has been updated, indicates the configuration has been updated. Click on the “X” button to close this window. 
14. Next, we will test Device Binding by connecting the user Ruby Kane from a different device than the device the user is bound to. 

In this example, we connect the user Ruby Kane from an iOS device.

1. On the iOS device, login to the ISA web console using the remote user’s credentials.
2. Click on the iOS icon to download the ISA User Agent.
3. From the Apps Store, download the ISA User Agent for iOS.
4. In the User Agent app, enter the domain name assigned by InstaSafe and click Login
5. In the authentication window, enter the username and password for the user. In this example, the credentials for the user Ruby Kane have been entered.
   
6. Click Sign In.
7. The Agent will attempt to connect but will be blocked by the ISA Controller. The user will see the message “Error! Device not authorized”
8. On the ISA web console, navigate to the DEVICES & CHECKS > Devices page. On this page, although the User Agent was not successful in connecting, the device information would have been captured and a new  device will be listed. In this example, the information of the iOS device has been captured and a new device with the name ruby_device_2 has been created.  The ISA web console administrator may choose to add this device to the user’s Device Binding configuration.

In the event you are unable to configure Device Binding by following these steps, please contact your organization's IT Team
