  • CentOS 7
  • RHEL 7
  • Oracle Linux 7
  • Amazon Linux 2.0
  • Debian 9
  • Ubuntu 16.04
  • Ubuntu 18.04

Dependencies

Linux Security 64 requires the following packages to be installed before installing the product:

CentOS, RHEL, Oracle Linux, and Amazon Linux
  • fuse-libs
  • libcurl
  • python
Debian and Ubuntu 16.04
  • libfuse2
  • libcurl3
  • python
Ubuntu 18.04
  • libfuse2
  • libcurl4
  • python

Installation

Installing Linux Security 64 happens by first creating an installation package using Policy Manager and installing the product from the newly-created installer on the target machine.

Please, note that you will need the Policy Manager version 14.20 to be able to install and manage Linux Security 64.

  1. Configure the Policy Manager Server to use F-Secure beta GUTS2 server:

    1. Log into a host with Policy Manager Server 14.20.
    2. Stop Policy Manager Server by running systemctl stop fspms.
    3. Remove everything from /var/opt/f-secure/fspms/data/guts2/.
    4. Open file /etc/opt/f-secure/fspms/fspms.conf and add -Dguts2ServerUrl=<A href="http://guts2tp.sp.f-secure.com" target="_blank" rel="noopener noopener noreferrer">http://guts2tp.sp.f-secure.com</A> to additional_java_args config parameter.
    5. Start Policy Manager Server by running systemctl start fspms

  2. Create the installation package:

    1. In Policy Manager Console, select Tools > Installation Packages from the menu. This opens the Installation Packages window.
    2. Click import.
    3. Select Linux Security installation package you want to use and click Import.
    4. Select the imported installation package in the packages list and click Export.
    5. Specify a name and a folder for the exported zip file. A Remote Installation Wizard window will appear.
    6. Click Next.
    7. Enter your license keycode for the product and click Next.
    8. Adjust the address of your Policy Manager Server and it’s HTTP and HTTPS ports if you need and click Finish.

  3. Copy the exported zip file to the Linux host in your network.

  4. Install the product:

    1. Log into the Linux host as root.
    2. Make sure you have the prerequisites installed (refer to dependencies section above).
    3. Extract the zip file into an empty directory.
    4. Run the following command: bash f-secure-linuxsecurity/f-secure-linuxsecurity-installer
    5. Read and accept the license terms when prompted.
    6. After the installation process finishes, Policy Manager Console will shortly show the Linux host in Pending hosts list.

Uninstallation

You can uninstall the product from the command line.

  1. Log in to the Linux host as root.
  2. Run the uninstallation command:
  • RHEL-based distributions: rpm -e f-secure-linuxsecurity
  • Debian-based distributions: dpkg -r f-secure-linuxsecurity

Known Issues

  • CSLP-3285: Manual and scheduled scanning are present on the GUI but currently are not operational. You can use the “fsanalyze” command to perform manual scanning from the command line.
  • CSLP-3288: Fsdiag generation does not work from the GUI. Use the command-line tool directly on the node, instead.
  • CSLP-3286: The update service currently does not generate alerts in case of failures.
  • CSLP-3291: Service status and statistics are currently not displayed in the policy manager UI.
  • CSLP-3289: Alerts are not mirrored in the system log.
  • CSLP-3292: Specifying special files or files in /proc and /sys in manual scanning may hang the product.
  • CSLP-3293: Debian-based systems are shown as "Unknown" in the Policy Manager Console.
  • CSLP-3309: Uninstall leaves 'fsaccd' process running. As a workaround, kill the fsaccd main process manually.
    A re-install will fail if the process is still running.

    We will be very disappointed if you can't install and use the command line client without having a Policy Manager. What we do is install the single client and programmatically do manual command line scans on the server (then we process and store the output from the scanner). We don't need on-access or integrity checking functionality (surely this can be turned off?). I hope it will be possible to purchase single licenses like before.

    At the moment of release, it will not be possible to use LS64 with no PM.

    Soon after, it might be possible, but to prepare installer you will have to use PM at least once.

    Also, we are not going to have cheap command-line only license any more, it is bad business for us. You will have to purchase Client or Server Edition.

    For the use case of "just scanning", we are going to release new version of Scanning and Reputation Server/Service that can be used unattended.

    Thanks for the reply. If we have to get the PM and Server license, it doesn't matter so much, as long as we are able to use the command line client as before (i.e. turn off on-access and read stdout/stderr and exit codes from the command line client ).

    Dear Sirs,

     

    I would like to understand how this tiny, 3MB sized "F-Secure 64 for Linux Security" package is able to meet or exceed the anti-virus  and other protective capabilities of the previous, almost 200MB sized "FSAV Linux Security 11.10.68" package?

     

    Thanks in advance, Yours Sincerely:
    Tamas Feher, Hungary.

    Great release, thank you. We were waiting for the return of the Policy Manager Proxy support. I see that the Linux Security 64 user manual was not updated : where can I find a documentation explaining how to link to a Policy Manager Proxy ?

    Kindly,

    M.

    New Linux Security 64 Update has been Released

    A new BaseGuard update (1.0.482) and a new FSBG update (1.0.471) have been released. BaseGuard and FSBG are part of Linux Security 64. This update includes the following changes:

    • CSLP-3722: Rapid Detection and Response functionality was added (see below).
    • CSLP-3542: Optimized performance when on-access scanning and integrity checking are turned off.
    • CSLP-3780: Fixed an issue where large number of mount points could cause product to stop working.
    • CSLP-3661: Fixed an issue where system could get stuck during shutdown if a particular autofs & NFS configuration was used.
    • Miscellaneous enhancements and bug fixes.

    Rapid Detection and Response Support

    Requirements

    RDR functionality requires the auditd service to be installed and running on the system. Please, see known issues below.

    Licensing

    Please, use "PSB Server Protection Premium + RDR" subscription in order to deploy Linux Protection with RDR.

    Supported systems

    The compatibility list is the same as for Linux Protection with exclusions. The following Linux distributives are not supported due to RDR sensor incompatibility:

    • SLES 12 SP 5
    • SLES 15
    • Ubuntu 20.04
    • Oracle Linux with UEK kernel

    Known issues

    • It is required to install, enable and start the auditd package on your system before installing Linux Protection with RDR. Without auditd, RDR sensor installation will fail. If RDR sensor installation fails, an error like this will be printed to the system journal:
    "Sep 29 14:07:37 localhost fsbg[6692]: update installation failed: /sensor/1601277158"

    It is possible to fix the failed sensor installation by installing auditd and running the command

    "/opt/f-secure/baseguard/bin/update $(/opt/f-secure/baseguard/bin/update --list | grep sensor | cut -d ' ' -f 1)";
    • On Debian 10 with SELinux enabled the RDR sensor and auditd can fail in some configurations
    • It is recommended to test the RDR sensor on the expected workload before deploying it into production, especially in network-heavy applications
