4.5 Configure the Sophos Mobile web server
Sophos Mobile includes a web server component for providing the content of the Sophos Mobile
Admin and Self Service Portal web applications. You can configure the web server to adjust it to your environment.
HTTP requests to a web server include a Host field in the request header, specifying the web application to process the request. An attacker can potentially manipulate the value of that Host field to provoke unintended behavior.
After installation, the web server component of Sophos Mobile doesn’t verify the value of the Host field. We recommend you configure the web server so that it only accepts requests directed to your domain name.
1. On the computer on which you’ve installed the Sophos Mobile server, run the script %MDM_HOME
%\tools\HostValidationUndertowFilter\addModule.bat
Replace %MDM_HOME% by your Sophos Mobile installation folder.
2. Open the file %MDM_HOME%\wildfly\standalone\configuration\smc-config.xml
in a text editor and search for the following section:
<filter name="hostheadervalidation" ...>
<param name="allowedHosts" value="localhost"/>
</filter>
3. After localhost , add your domain name for Sophos Mobile Admin and for the Self Service Portal.
For example if your domain name is smc.example.com
, change the line as follows:
<param name="allowedHosts" value="localhost,smc.example.com"/>
If your Sophos Mobile server can be accessed under more than one domain name, enter all names separated by commas.
4. Save the file smc-config.xml
5. Restart the Sophos Mobile service.
4.6 Change the SQL login language
If you have configured the Sophos Mobile server to use SQL Server authentication to connect to the database, the SQL login language must be set to English. Otherwise, an error occurs when the
Sophos Mobile service is started.
This topic describes how to change the SQL login language to English.
1. Stop the Sophos Mobile service.
2. Open SQL Server Management Studio on the server and select Security > Logins.
3. On the General page of the Login Properties, set Default language to English, then click OK to save the changes.
4. Restart the Sophos Mobile service.

5 Standalone EAS proxy
You can set up an EAS proxy to control the access of your managed devices to an email server.
Email traffic of your managed devices is routed through that proxy. You can block email access for devices, for example a device that violates a compliance rule.
The devices must be configured to use the EAS proxy as email server for incoming and outgoing emails. The EAS proxy will only forward traffic to the actual email server if the device is known in
Sophos Mobile and matches the required policies. This guarantees higher security as the email server does not need to be accessible from the Internet and only devices that are authorized
(correctly configured, for example with passcode guidelines) can access it. Also, you can configure the EAS proxy to block access from specific devices.
There are two types of EAS proxy:
• The internal EAS proxy that is automatically installed with Sophos Mobile. It supports incoming
ActiveSync traffic as used by Microsoft Exchange or IBM Notes Traveler for iOS and Samsung
Knox devices.
• A standalone EAS proxy that can be downloaded and installed separately. It communicates with the Sophos Mobile server through an HTTPS web interface.
Note
For performance reasons, we recommend you use the standalone EAS proxy server instead of the internal version when email traffic for more than 500 client devices must be managed.
Note
Because macOS doesn’t support the ActiveSync protocol, you can’t use the internal or the standalone EAS proxy to filter email traffic coming from Macs.
Features
The standalone EAS proxy has additional features compared to the internal version:
• Support for IBM Notes Traveler for non-iOS devices (for example, Android). The Traveler client for these devices uses a protocol (not ActiveSync) that is not supported by the internal EAS proxy.
• Support for multiple Microsoft Exchange or IBM Notes Traveler email servers. You can set up one
EAS proxy instance per email server.
• Load balancer support. You can set up standalone EAS proxy instances on several computers and then use a load balancer to distribute the client requests among them.
• Support for certificate-based client authentication. You can select a certificate from a certification authority (CA), from which the client certificates must be derived.
• Support for email access control through PowerShell. In this scenario, the EAS proxy service communicates with the email server through PowerShell to control the email access of your managed devices. Email traffic happens directly from the devices to the email server and is not
routed through a proxy. See Set up email access control through PowerShell (page 15).
• The EAS proxy remembers the device status for 24 hours. If the Sophos Mobile server is offline, for example during an update, email traffic is filtered based on the last known device status. After 24 hours, all email traffic is blocked.

Sophos Mobile
Note
For non-iOS devices, filtering abilities of the standalone EAS proxy are limited due to the specifics of the IBM Notes Traveler protocol. Traveler clients on non-iOS devices do not send the device ID with every request. Requests without a device ID are still forwarded to the Traveler server, even though the EAS proxy is not able to verify that the device is authorized.
5.1 EAS proxy usage scenarios
Note
Additional to the information provided in this section, the Sophos Mobile server deployment guide contains schematic diagrams for the integration of the standalone EAS proxy into your company’s infrastructure. We recommend that you read the information before performing the installation and deployment of the standalone EAS proxy.
You use IBM Notes Traveler (formerly IBM Lotus Notes Traveler) for noniOS devices
The internal EAS proxy is not suitable for this scenario because it only supports the ActiveSync protocol, which is used by Microsoft Exchange and by IBM Notes Traveler for iOS devices. IBM
Notes Traveler for non-iOS devices (for example, Android) uses a different protocol that is supported by the standalone EAS proxy.
For non-iOS devices, dedicated Traveler client software is required. This software is available through <traveler-server>/servlet/traveler or the Traveler file system. The Install App and Uninstall App features of Sophos Mobile can be used to install and uninstall the Traveler client software. Configuration has to be performed manually.
You want to support multiple backend servers
With the standalone EAS proxy you can set up multiple instances of backend email systems. Each instance needs an incoming TCP port. Each port can connect to a different backend. You need one
URL per EAS proxy instance.
You want to set up load balancing for EAS
You can set up standalone EAS proxy instances on several computers and then use a load balancer to distribute the client requests among them.
For this scenario an existing load balancer for HTTP is required.
You want to use client certificate based authentication
For this scenario an existing PKI is required and the public part of the CA certificate has to be set in the EAS proxy.

Sophos Mobile
You need to manage more than 500 devices
For performance reasons, we recommend you use the standalone EAS proxy server instead of the internal version when email traffic for more than 500 client devices must be managed.
5.2 Download the EAS proxy installer
1. Sign in to Sophos Mobile Admin as super administrator.
2. On the menu sidebar, under SETTINGS, click Setup > Sophos setup, and then click the EAS
proxy tab.
3. Under External, click the link to download the EAS proxy installer.
The installer file is saved to your local computer.
5.3 Install the standalone EAS proxy
Prerequisites:
• You’ve installed and set up Sophos Mobile.
• All required email servers are accessible. The EAS proxy installer will not configure connections to servers that are not available.
• You are an administrator on the computer where you install the EAS proxy.
Note
The Sophos Mobile server deployment guide contains schematic diagrams for the integration of the standalone EAS proxy into your company’s infrastructure. We recommend that you read the information before performing the installation and deployment of the standalone EAS proxy.
1. Run Sophos Mobile EAS Proxy Setup.exe
to start the Sophos Mobile EAS Proxy - Setup
Wizard.
2. On the Choose Install Location page, choose the destination folder and click Install to start installation.
After the installation has been completed, the Sophos Mobile EAS Proxy - Configuration Wizard is started automatically and guides you through the configuration steps.
3. In the Sophos Mobile server configuration dialog, enter the URL of the Sophos Mobile server the
EAS proxy will connect to.
You should also select Use SSL for incoming connections (Clients to EAS Proxy) to secure the communication between clients and the EAS proxy.
Optionally, select Use client certificates for authentication if you want the clients to use a certificate in addition to the EAS proxy credentials for authentication. This adds an additional layer of security to the connection.
Select Allow all certificates if your Sophos Mobile server presents varying certificates to the
EAS proxy, for example because there are several server instances behind a load balancer, and each instance uses a different certificate. When this option is selected, the EAS proxy will accept any certificate from the Sophos Mobile server.
12 Copyright © Sophos Limited
Sophos Mobile
CAUTION
Because the Allow all certificates option reduces the security level of the server communication, we strongly recommend that you select it only if required by your network environment.
4. If you selected Use SSL for incoming connections (Clients to EAS Proxy) before, the
Configure server certificate page is displayed. On this page you create or import a certificate for the secure (HTTPS) access to the EAS proxy.
Note
Your Sophos product delivery includes the SSL Certificate Wizard to request your SSL/TLS
• If you do not have a trusted certificate yet, select Create self-signed certificate.
• If you have a trusted certificate, click Import a certificate from a trusted issuer and select one of the following options from the list:
— PKCS12 with certificate, private key and certificate chain (intermediate and CA)
— Separate files for certificate, private key, intermediate and CA certificate
5. On the next page, enter the relevant certificate information, depending on the type of certificate that you selected.
Note
For a self-signed certificate, you need to specify a server that is accessible from the client devices.
6. If you selected Use client certificates for authentication before, the SMC client authentication
configuration page is displayed. On this page, you select a certificate from a certification authority
(CA), from which the client certificates must be derived.
When a client tries to connect, the EAS proxy will check if the client certificate is derived from the
CA that you specify here.
7. On the EAS Proxy instance setup page, configure one or more EAS proxy instances.
• Instance type: Select EAS proxy.
• Instance name: A name to identify the instance.
• Server port: The port of the EAS proxy for incoming email traffic. If you set up more than one proxy instance, each of these must use a different port.
• Require client certificate authentication: Email clients must authenticate themselves when connecting to the EAS proxy.
• ActiveSync server: The name or IP address of the Exchange ActiveSync Server instance with which the proxy instance will connect.
• SSL: Communication between the proxy instance and Exchange ActiveSync Server is secured by SSL or TLS (depending on what the server supports).
• Allow EWS subscription requests from Secure Email: Select this to allow the Sophos
Secure Email app on iOS to subscribe to push notifications through Exchange Web Services
(EWS). Push notifications inform the device when there are messages for Secure Email.

Note
— By default, the EAS proxy blocks all requests to the Exchange server’s EWS interface for security reasons. If you select this check box, subscription requests are allowed.
Other requests remain blocked.
— For information on how to configure EWS for your Exchange server, see Sophos knowledge base article 127137 .
• Enable Traveler client access: Only select this check box if you need to allow access by IBM
Notes Traveler clients on non-iOS devices.
8. After entering the instance information, click Add to add the instance to the Instances list.
For every proxy instance, the installer creates a certificate that you need to upload to the Sophos
Mobile server. After you have clicked Add, a message window opens, explaining how to upload the certificate.
9. In the message window, click OK.
This will open a dialog, showing the folder in which the certificate has been created.
Note
You can also open the dialog by selecting the relevant instance and clicking the Export config
and upload to Sophos Mobile server link on the EAS Proxy instance setup page.
10. Make a note of the certificate folder. You need this information when you upload the certificate to
Sophos Mobile.
11. Optional: Click Add again to configure additional EAS proxy instances.
12. When you have configured all required EAS proxy instances, click Next.
The server ports that you entered are tested and inbound rules for the Windows Firewall are configured.

Sophos Mobile
This completes the initial setup of the standalone EAS proxy.
Note
Every day, the EAS proxy log entries are moved to a new file, using the naming pattern
EASProxy.log.yyyy-mm-dd . These daily log files are not deleted automatically and thus may cause disk space issues over time. We recommend that you set up a process to move the log files to a backup location.
5.4 Set up email access control through
PowerShell
You can set up a PowerShell connection to an Exchange or an Office 365 server. This means that the EAS proxy service communicates with the email server through PowerShell to control the email access for your managed devices. Email traffic is routed directly from the devices to the email server.
It is not routed through a proxy.
Note
For a schematic of the PowerShell communication, see the Sophos Mobile server deployment guide .
Note
Because macOS doesn’t support the ActiveSync protocol, you can’t use PowerShell to control email access by Macs.
The PowerShell scenario has these advantages:
• Devices communicate directly with the Exchange server.
• You do not need to open a port on your server for incoming email traffic from your managed devices.
Supported email servers are:
• Exchange Server 2013
• Exchange Server 2016
• Office 365 with an Exchange Online plan
To set up PowerShell:
1. Configure PowerShell.
2. Create a service account on the Exchange server or in Office 365. This account is used by Sophos
Mobile to execute PowerShell commands.
3. Set up one or more PowerShell connection instances to Exchange or Office 365.
4. Upload the instance certificates to Sophos Mobile.
Configure PowerShell
1. On the computer on which you are going to install the EAS proxy, open Windows PowerShell, as an administrator, and enter:
PS C:\Windows\system32> Set-ExecutionPolicy RemoteSigned
Copyright © Sophos Limited 15
Sophos Mobile
16
Note
If PowerShell is not available, install it as described in the Microsoft article Installing Windows
PowerShell (external link) .
2. If you want to connect to a local Exchange server, open Windows PowerShell as administrator on that computer and enter the same command as before:
PS C:\Windows\system32> Set-ExecutionPolicy RemoteSigned
Note
This step is not required for Office 365.
Create a service account
3. Log in to the relevant admin console:
• For Exchange Server 2013/2016: Exchange Admin Center
• For Office 365: Office 365 Admin Center
4. Create a user account. This account is used as a service account by Sophos Mobile to execute
PowerShell commands.
• Use a user name like smc_powershell that identifies the account purpose.
• Turn off the setting to make the user change their password the next time they log in.
• Remove any Office 365 license that was automatically assigned to the new account. Service accounts don’t require a license.
5. Create a new role group and assign it the required permissions.
• Use a role group name like smc_powershell .
• Add the Mail Recipients and Organization Client Access roles.
• Add the service account as a member.
Set up PowerShell connections
6. Use the setup wizard as if you would set up a standalone EAS Proxy. On wizard page EAS Proxy
instance setup, configure the following settings:
• Instance type: Select PowerShell Exchange/Office 365.
• Instance name: A name to identify the instance.
• Exchange server: The name or IP address of the Exchange server (for a local Exchange server installation) or outlook.office365.com
(for Office 365). Don’t include a prefix https:// or a suffix /powershell . These are added automatically.
• Allow all certificates: The certificate that the Exchange server presents is not verified.
Use this for example if you have a self-signed certificate installed on your Exchange server. Because the Allow all certificates option reduces the security level of the server communication, we strongly recommend that you select it only if required by your network environment.
• Service account: The name of the user account you created in the Exchange or Office 365 admin console.
• Password: The password of the user account.
7. Click Add to add the instance to the Instances list.

Sophos Mobile
8. Repeat the previous steps to set up PowerShell connections to other Exchange or Office 365 servers.
9. Complete the setup wizard as described in
Install the standalone EAS proxy (page 12).
Upload certificates
10. Sign in to Sophos Mobile Admin as a super administrator.
11. On the menu sidebar, under SETTINGS, click Setup > Sophos setup, and then click the EAS
proxy tab.
12. Optional: Under General, select Restrict to Sophos Secure Email to restrict email access to the
Sophos Secure Email app, available for Android and iOS.
This prevents other email apps from connecting to your email server.
13. Under External, click Upload a file. Upload the certificate that the configuration wizard created.
If you have set up more than one instance, repeat this for all instance certificates.
14. Select Save.
15. In Windows, open the Services dialog and restart the EASProxy service.
This completes the initial setup of PowerShell connections. Email traffic between a managed device and the Exchange or Office 365 servers is blocked if the device violates a compliance rule. You can block an individual device by setting the email access mode for that device to Deny.
Note

6 Load balancing and high availability
Sophos Mobile makes it possible to set up a high-availability environment. This ensures that the
SMC service remains externally accessible and tasks can be further processed even after failure of a Sophos Mobile server node. To achieve this, load balancing, that distributes client and browser sessions by using DNS Round Robin to the available nodes, is required.
The following describes setting up clustering for Sophos Mobile and configuring load balancing with
Sophos UTM.
6.1 Requirements
• One separate Windows server for each Sophos Mobile server node.
• All nodes must be on the same network.
• One Microsoft SQL or MySQL database server or cluster.
• Sophos UTM or Apache Reverse Proxy (mod_proxy) for load balancing. Load balancer must support permanent session cookies and official SSL/TLS web server certificates.
Note
For detailed information about the installation requirements see the Sophos Mobile 9.5 release notes .
Architecture
For an example of a three-node Sophos Mobile cluster see the Sophos Mobile server deployment guide .
For multicast communication between the individual Sophos Mobile server nodes, optionally a separate network can be used. The network interface to be used can be selected during cluster configuration, as described in
(page 19). It may also be a VLAN.
Note
If you want to operate a second Sophos Mobile cluster for test purposes, a separate network is needed.
Ports and protocols
The following table shows the required ports and protocols for communication between the individual nodes of a Sophos Mobile server cluster.

Server certificates
When you set up Sophos Mobile, you configure an SSL/TLS web server certificate that allows the Sophos Mobile Control app to establish a secure connection to the Sophos Mobile server. We recommend that you use a certificate that is issued by a globally trusted certificate authority (CA). In a clustered environment with several Sophos Mobile server nodes behind a load balancer, this might not be practical. You might want to use a self-signed certificate instead.

Request an SSL/TLS certificate (page 5)
Your Sophos product delivery includes the SSL Certificate Wizard to request your SSL/TLS certificate for the Sophos Mobile EAS proxy.
6.2 Set up cluster nodes
To set up a clustered environment you install the first node as described in
Sophos Mobile server (page 6). Clustering itself is then activated using the Configuration Wizard.
For all other nodes, the database created during installation of the first node has to be selected and clustering has to be activated.
Note
It is also possible to configure an existing SMC server for clustering and to extend the environment by adding additional nodes.
6.2.1 Set up the first node
1. Install Sophos Mobile as described in
Install and set up the Sophos Mobile server
(page 6) and write down the name of the database you created. Specify this database when installing further nodes.
2. At the end of the installation deselect the Start Sophos Mobile server now option in the Sophos
Mobile - Installation finished dialog.
Note
If the Sophos Mobile service has already been started it will automatically be stopped and restarted during the configuration described later in this section. Alternatively, you can manually stop the service from the menu of the Sophos Mobile system tray icon.
3. On the server, click Start, go to Sophos Mobile and click SMC Configuration Wizard.
4. The Welcome page of the Sophos Mobile Configuration Wizard is displayed. Click Next.
5. On the Database Selection page, select Skip database configuration and click Next.

6. On the Choose configuration steps page, select Configure cluster support and click Next.
7. On the Cluster Configuration page, use the drop-down list of available network interfaces to select the interface that will be used for multicast communication between the server node that you are about to set up and the other nodes.
8. Click through the remaining pages of the configuration wizard. Make sure that you click Yes when asked to start the SMC service.
The configuration of the first SMC server node is now complete. Click Finish in the Sophos Mobile
- Configuration Wizard finished dialog.
6.2.2 Set up further nodes
(page 6).
2. On the Database selection page, select the database you created when you installed the first node and click Next.
The Database configuration dialog box is displayed. It shows the progress of the configuration process.
3. On the Database configuration page, wait until the configuration process has finished, then click
Next.
4. On the Choose configuration steps page, select Configure cluster support and click Next.
5. On the Configure server certificate page, create a self-signed certificate as described in
Install and set up the Sophos Mobile server
(page 6) and click Next.
6. On the Cluster Configuration page, use the drop-down list of available network interfaces to select the interface of the Sophos Mobile server node that you are about to set up, then click Next.
7. Click through the remaining pages of the configuration wizard. On the Sophos Mobile -
Installation finished page, select Start Sophos Mobile server now to start the cluster node that you just configured.
8. If you’ve configured the web server component of Sophos Mobile on the first node to only accept requests directed to your domain name, repeat this for all other nodes. See
If required, repeat this procedure to configure additional nodes.
6.3 Set up load balancing with Sophos UTM
This topic describes how to set up Sophos UTM as a load balancer for a cluster of Sophos
Mobile server nodes. For more information on configuring Sophos UTM, see the Sophos UTM documentation.
Note
• In order to use Sophos UTM for clustering you need a Sophos UTM license with a Sophos
Webserver Protection subscription.
• As described later in this section, you need to specify a certificate to protect the communication between the managed devices and the virtual web server that you set up in
Sophos UTM. For simplicity, we recommend that you use the same certificate that you used for the Sophos Mobile server (see
Request an SSL/TLS certificate
(page 5)). If you used a self-signed certificate, it is mandatory that you use that same certificate.
1. Log into Sophos UTM WebAdmin.

9. Click New Virtual Webserver to add a virtual web server for the cluster.
10. In the Add Virtual Webserver dialog box, make the following settings: a) Name: Enter a descriptive name for the virtual web server (for example SMC cluster ).
b) In the Interface list, select the WAN interface over which the cluster should be accessible from outside.
c) Type: Select Encrypted (HTTPS) & redirect.
d) In the Certificate list, select the web server’s certificate you uploaded beforehand.
e) Domains (only with wildcard certificate, that is a public key certificate that can be used with multiple subdomains): Enter the domains the web server is responsible for, for example shop.example.com
, or use the Action icon to import a list of domain names.
Domains must be entered as fully qualified domain names (FQDN).
You can use an asterisk (*) as a wildcard for the domain prefix, for example,
*.mydomain.com
. Domains with wildcards are considered as fallback settings: The virtual web server with the wildcard domain entry is only used when no other virtual web server with a more specific domain name is configured.
Example: A client request to a.b.c
will match a.b.c
before *.b.c
before *.c
.
f) Real Webservers: Select the SMC nodes you created beforehand.

7 Update Sophos Mobile
Sophos Mobile server installations can be updated directly from versions 8.5, 8.6, and 9 to 9.5.
Older versions need to be updated to Sophos Mobile 8.5 beforehand. For details, see the Sophos
Mobile 8.5 documentation.
7.1 Update Sophos Mobile server
To update your Sophos Mobile server installation to version 9.5, start the Sophos Mobile 9.5 installer and follow the instructions. The installer automatically detects if an existing installation needs to be updated.
A system property check will be performed before the update starts. If all checks are passed you can proceed with the update. Database and files will be updated automatically without any user interaction. Once the update is complete, the Sophos Mobile service will be started again.
Note
If you used Windows Authentication during your initial Sophos Mobile server installation the Start
Sophos Mobile server now option is grayed out. You have to start the service manually.
7.2 Post-update tasks
7.2.1 Re-configure the Sophos Mobile web server
If you’ve configured the web server component of Sophos Mobile to only accept requests directed
(page 9).
7.3 Update a server cluster
When updating a cluster of Sophos Mobile server nodes, it is important that all nodes are running on the same version at all times, and that the server version matches the database version. To do this:
1. Shut down all server nodes by stopping the Sophos Mobile service on the relevant computers.
2. Update the first node as described in
(page 23).
This also updates the database.
3. Start the updated server node and check that the update was successful.
4. Update the remaining server nodes.

Tip
If you are using the standalone EAS proxy, your managed devices can access your email server even when all Sophos Mobile server nodes are stopped. This is because the EAS proxy caches the device status for up to 60 minutes when not connected to the Sophos Mobile server.
7.4 Update standalone EAS proxy
To update your standalone EAS proxy, run the EAS proxy installer and follow the instructions. The installer automatically detects if an existing installation needs to be updated.
If you are using a cluster of EAS proxy server nodes behind a load balancer, you can update these nodes independently of each other and in any sequence.
Tip
Do not stop all EAS proxy server nodes at the same time. This makes sure that email communication of your managed devices is not interrupted during the update.
