Overview

The Sophos Anti-Virus filter uses the Sophos Anti-Virus Interface (SAVI) to screen messages for viruses. You can configure the behavior of the Sophos library using configuration options available in the Sophos Anti-Virus filter.

[Important] Important

Because the API Gateway does not ship with any Sophos binaries, the API Gateway must be installed on the same machine as the Sophos AV distribution. On Linux or Solaris, before starting the API Gateway, ensure that the Sophos AV lib directory is on your LD_LIBRARY_PATH. Similarly, on Windows, this directory must be on the system PATH> (the Sophos installation automatically puts this directory on the system path).

Prerequisites

Integration with Sophos requires Sophos SAV Interface version 4.8. You must add the required third-party binaries to your API Gateway and Policy Studio installations.

API Gateway

To add third-party binaries to the API Gateway, you must perform the following steps:

  1. Add the binary files as follows:

    • Add .jar files to the install-dir/apigateway/ext/lib directory.

    • Add .dll files to the install-dir\apigateway\Win32\lib directory.

    • Add .so files to the install-dir/apigateway/platform/lib directory.

  2. Restart the API Gateway.

Policy Studio

To add third-party binaries to Policy Studio, you must perform the following steps:

  1. Select Windows > Preferences > Runtime Dependencies in the Policy Studio main menu.

  2. Click Add to select a JAR file to add to the list of dependencies.

  3. Click Apply when finished. A copy of the JAR file is added to the plugins directory in your Policy Studio installation.

  4. Click OK.

  5. Restart Policy Studio.

Sophos configuration settings

All SAVI configuration options take the form of a name-value pair. Each name is unique and its corresponding value controls specific behavior in the Sophos anti-virus library (for example, decompress .zip files to examine their content). You can specify these SAVI configuration settings in the Sophos configuration settings section:

Name:

The Sophos Anti-Virus filter ships with two sets of default configuration settings: one for UNIX-based platforms, and the other for Windows platforms. Select the appropriate configuration settings for your target platform from the drop-down list.

You can create a new set of configuration options by clicking the Add button, and adding the name-value pairs to the table provided. For convenience, you can base a new configuration set on a previously existing one, including the default Windows and UNIX sets. In this way, you can create a new configuration set that inherits from the default set, and then adds more configuration options.

To add a new configuration name-value pair, click the Add button under the table, and configure the following fields in the dialog:

Name:

Enter a name for the SAVI configuration option. This name must be available in the version of the SAVI library that is used by the API Gateway. Please refer to your SAVI documentation for a complete reference on available options.

Value:

Enter an appropriate value for the SAVI configuration option entered above. Please refer to your SAVI documentation for more information on acceptable values for this configuration option.

Type:

Select the appropriate type of this configuration option from the drop-down list. Please refer your SAVI documentation for more information on the type of the value for this configuration option.
