Configuring Access Policy Manager for MDM applications
Overview: Configuring APM for device posture checks with endpoint
management systems
MDM solutions are responsible for managing user devices, where a user
enrolls a device (or devices) and sets certain compliance policy which dictates whether a device
is compliant or non-compliant. The endpoint management system determines whether the APM
recognizes the device before allowing access from the access policy. An endpoint management
system also controls the corporate data on mobile devices. Edge Client establishes a VPN
connection with APM, and an endpoint management system (Airwatch, MaaS360, or Intune) manages and
sends device details to APM.
To reduce the number of queries to the MDM server, the Database Synchronization Manager lists
all the compliant devices in the case of Airwatch and MaaS360 & non-compliant devices in the
case of Microsoft Intune and stores the information in the local cache. The synchronization
interval is configurable to fit your situation and is refreshed after every 4 hours by default to
get a new list of devices. When a device tries to connect through the F5 Access client, the local
cache is queried for the device ID. When the device ID is not found, the device is verified by
the MDM server. When the device is found compliant, the device ID is added to the local cache
after the user logs in.
Supported Devices
Only iOS devices and Android devices with VPN access to APM from specific mobile device apps
that are being managed by MDM (F5 Access Client Apps) are supported. For example, if you connect
to APM WebTop from a browser in a device then APM will not get a device ID and cannot check for
device compliance.
F5 Access for MacOS and Windows are currently not
supported.
For devices with iOS 12 and later, F5 Access client could not retrieve device ID from iOS due
to Apple imposed constraints and compliance check failed. Microsoft's Network access control
(NAC) integration with Intune provides a new temporary NAC ID to identify the device. This ID is
pushed to the F5 Access client through the F5 Access profile in Intune. For iOS devices, the
device is always verified by the MDM server as the NAC ID is not stored in the local cache.
To use NAC for VPN on iOS devices, the
Enable network access control
(NAC)
option must be selected when configuring the VPN profile for F5 Access in
Microsoft Intune.
Creating an endpoint management system connector with Airwatch
You must create a Server SSL profile on a BIG-IP system and
have access to an Airwatch system.
An endpoint management system on BIG-IP Access
Policy Manager (APM) is an object that stores information about the device management
server, such as IP addresses and API credentials. You can configure more than one
endpoint management system on the same BIG-IP system. APM polls devices connected to the
configured endpoint management systems.

when the Named scope has configured the session
and is checked based on the value and string
configured in the Named scope field.
In the Language Settings area, add and remove
accepted languages, and set the default language.
A browser uses the highest priority
accepted language. If no browser language matches the accepted languages list,
the browser uses the default language.

profile displays in the Access Profiles List. Default-log-setting is assigned to the
access profile.
Configuring an access policy to include endpoint management
integration
You can configure an access policy to perform
compliance checks for connected devices. The Managed Endpoint Status action determines
whether APM recognizes a device with a device ID. The Managed Endpoint Notification
action sends a push notification message to a device. You can create access policy
checks using session variables and device posture information to allow or deny access.
On the Main tab, click
Access
Profiles /
Policies
.
The Access Profiles
(Per-Session Policies) screen opens.
In the Access Policy column, click the
Edit
link for the endpoint
management type access profile you want to configure.
The visual policy editor
opens the access policy in a separate screen.
Click the
(+)
icon anywhere in the
access policy to add a new item.
Only an applicable subset of access policy items is
available for selection in the visual policy editor for any access profile
type.
A popup screen opens, listing
predefined actions on tabs such as General Purpose, Authentication, and so
on.
Add a Managed Endpoint Status action:
From the Endpoint Security (Server-Side)
list, select
Managed
Endpoint Status

icon anywhere in the
access policy to add a new action item.
For example, as shown in the
Access policy with endpoint management
integration
image below, the Managed Device Status action performs the
compliance checks on the device for allowing network access and sends
notification messages to the non-compliant device.
