Configure proxies

You can configure proxies between various Trend Micro servers and services.

Register a proxy in Workload Security

1. In the Workload Security console, go to Administration > System Settings > Proxies.

2. In the Proxy Servers area, click New > New Proxy Server.

3. In the Name and Description fields, enter a friendly name and description for your proxy.

4. For the Proxy Protocol, select either HTTP, SOCKS4, SOCKS5, or Proxy Auto-Configuration (PAC). Not all protocols are supported by all components. See Supported proxy protocols for details.

   The proxy in the PAC file only supports HTTP and direct connection PACs.

5. In the Address and Port fields, enter the IP address or URL of the proxy as well as its port. The default values are 8080 or 80 for HTTP, 3128 for the Squid HTTP proxy, and 1080 for SOCKS 4 and 5.

6. Enable Proxy requires authentication credentials if you previously set up your HTTP or SOCKS 5 proxy to require authentication from connecting components. Enter those credentials in the User Name and Password fields.

Supported proxy protocols

The following table lists the proxy protocols supported by the Trend Micro services and clients. You need this information when registering a proxy, and when configuring a proxy through dsa_control.

Connect to the primary security update source via proxy

The primary security update source for the new improved relay is the Workload Security relay. Deep Security Agent 20.0.0-3964 or later can connect to Workload Security relays via this proxy setting.

You can connect your agents to your primary security update source via a proxy. By default, the primary security update source is the Trend Micro Update Server (also called Active Update).

Note that agents and appliances can only use the proxy if their assigned relay is not available and they have been granted explicit permission to access the primary update source.

1. Make sure you are using the agent version 10.0 or later, because connections through a proxy are not supported on earlier versions.

2. Register a proxy in Workload Security.

3. In the Workload Security console, click the Administration > System Settings > Proxies tab.

4. In the Proxy Server Use area, change the Primary Security Update Proxy used by Agents, Appliances, and Relays setting to point to the new proxy.

5. Click Save.

6. Restart the agents.

Connect to Workload Security via proxy

Agents connect to Workload Security during agent activation and heartbeats. There are two methods to connect an agent to Workload Security via a proxy.

cd C:\Program Files\Trend Micro\Deep Security Agent\
dsa_control -u myUserName:MTPassw0rd
dsa_control -x dsm_proxy://squid.example.com:443

/opt/ds_agent/dsa_control -u myUserName:MTPassw0rd
/opt/ds_agent/dsa_control -x dsm_proxy://squid.example.com:443

Connect to relays via proxy

Agents connect to their relay to obtain software and security updates. There are two methods to connect an agent to a relay via a proxy.

cd C:\Program Files\Trend Micro\Deep Security Agent\
dsa_control -w myUserName:MTPassw0rd
dsa_control -y relay_proxy://squid.example.com:443

/opt/ds_agent/dsa_control -w myUserName:MTPassw0rd
/opt/ds_agent/dsa_control -y relay_proxy://squid.example.com:443

Connect to Workload Security and Relays via Proxy Auto_Configuration (PAC) proxy

cd C:\Program Files\Trend Micro\Deep Security Agent\
dsa_control --pacproxyunpw myUserName:MTPassw0rd
dsa_control --pacproxy http://pac.example.com:80/proxy.pac

/opt/ds_agent/dsa_control --pacproxyunpw myUserName:MTPassw0rd
/opt/ds_agent/dsa_control --pacproxy http://pac.example.com:80/proxy.pac

Connect to the Smart Protection Network via proxy

Use the following procedure to configure a proxy between agents and the following services in the Smart Protection Network: Global Census, Good File Reputation, Predictive Machine Learning, and the Smart Protection Network itself.

1. Register a proxy in Workload Security.

2. In the Workload Security console, click Policies at the top.

3. In the main pane, double-click the policy that you use to protect computers that are behind the proxy.

4. Set up a proxy to the Global Census, Good File Reputation, and Predictive Machine Learning Services as follows:

   1. Click Settings on the left.

   2. In the main pane, select the General tab.

   3. In the main pane, look for the Network Setting for Census and Good File Reputation Service, and Predictive Machine Learning section.

   4. If Inherited is selected, the proxy settings are inherited from the parent policy. To change the settings for this policy or computer, clear the selection.

   5. Select When accessing Global Server, use proxy and in the list, select your proxy, or select New to specify another proxy.

   6. Save your settings.

5. Set up a proxy to the Smart Protection Network for use with Anti-Malware:

   1. Click Anti-Malware on the left.

   2. In the main pane, click the Smart Protection tab.

   3. Under Smart Protection Server for File Reputation Service, if Inherited is selected, the proxy settings are inherited from the parent policy. To change the settings for this policy or computer, clear the selection.

   4. Select Connect directly to Global Smart Protection Service.

   5. Select When accessing Global Smart Protection Service, use proxy and in the list, select your proxy or select New to specify another proxy.

   6. Specify your proxy settings and click OK.

   7. Save your settings.

6. Set up a proxy to the Smart Protection Network for use with Web Reputation:

   1. Click Web Reputation on the left.

   2. In the main pane, click the Smart Protection tab.

   3. Under Smart Protection Server for Web Reputation Service, set up your proxy, the same way you did under Anti-Malware in a previous step.

   4. With Web Reputation still selected on the left, select the Advanced tab.

   5. In the Ports section, select a group of port numbers that includes your proxy's listening port number, and then click Save.

      For example, if you are using a Squid proxy server, you would select the Port List Squid Web Server. If you do not see an appropriate group of port numbers, go to Policies > Common Objects > Lists > Port Lists and then click New to set up your ports.

   6. Save your settings.

7. Send the new policy to your agents. See Send policy changes manually.

Your agents can now connect to the Smart Protection Network through a proxy.
