Updating malware definitions on isolated Client Security hosts

If you have installed Client Security on hosts that do not have a network connection, you can update the malware definitions using the tool provided with Policy Manager.

Note: This procedure applies to Client Security versions 13 and newer.

The tool for downloading updates is bundled with Policy Manager and can be extracted with the provided scripts. When you run it on any machine with internet access, the tool downloads the latest updates and required diffs to generate an all-in-one archive.

By default, the tool uses the data\updates folder to store the downloaded update binaries. It also stores the update history to use as a reference for downloading the relevant diffs to the latest version.

In addition to the update binaries, you also need the fsaua-update tool to import the prepared updates. You can download this tool from the F-Secure website: https://download.f-secure.com/corpro/cs/current/fsaua-update.exe.

To update the malware definitions:

  1. Run the following command on the Policy Manager machine to prepare the tool:
    • Windows: <F-Secure installation folder>\Management Server 5\bin\prepare-fspm-definitions-update-tool.bat <destination folder>
    • Linux: /opt/f-secure/fspms/bin/prepare-fspm-definitions-update-tool <destination folder>
  2. Transfer the prepared binaries to a machine that has internet access, if necessary.
  3. Modify the tool configuration, if necessary:
    • conf\channels.json: this contains a list of the channels to be updated. By default, it includes updates for all the supported clients managed by Policy Manager, so we recommend that you leave only the Client Security versions necessary for your environment.
  4. Run the tool:
    • Windows: fspm-definitions-update-tool.bat
    • Linux: fspm-definitions-update-tool
    The resulting archive contains the full set of the latest definitions and diffs to this version. If all data is up to date, no archive is generated.
  5. Download the tool for importing the prepared updates: https://download.f-secure.com/corpro/cs/current/fsaua-update.exe.
  6. Transfer the prepared archive (data\f-secure-updates.zip by default) and the fsaua-update.exe import tool to the isolated Client Security host.

    Note: Copy both files to the same directory on the target host.

  7. Run fsaua-update.exe with administrator privileges.
