Product contents

F-Secure Internet Gatekeeper is a gateway product that acts as a virus scanning proxy for HTTP, SMTP, POP, and FTP protocols.

The product uses F-Secure’s scanning technologies to scan for malware that provides an outstanding protection level and fast, automatic updates to the scanning engines and anti-virus databases. With F-Secure’s Security Cloud, the product can react to new threats rapidly, which keeps the users protected and enhances the protection even further.

The product can be integrated with third-party HTTP proxies with the standard ICAP protocol. The content that is submitted to the ICAP service is scanned with F-Secure’s malware scanning technologies.

4.10.17 => 5.00.5

  • Support for F-Secure Real Time Protection Network was added to the HTTP proxy. When enabled, common files are identified by rapidly updating black and white lists. This saves system resources and improves the protection.
  • The malware scanning capabilities are now available by a standard ICAP interface. This enables integration with third party proxies that support ICAP.
  • The list of supported distributions was reworked to focus on the most popular, current and actively supported distributions.
  • Removed dependency to Java, which is a common source of security vulnerabilities. Java runtime environment is no longer distributed with the product. As a consequence, this release does not contain a web UI, but is also significantly smaller and lighter. Configuration is done by editing the configuration files directly.
  • Improved quality of RPM packages.
  • Improved the output from IGK init scripts.
  • Fixed CTS-91383: Added an option to control whether to transparently re-establish keepalive upstream HTTP connections.

If you are upgrading from a version earlier than 4.10.17, 4.11.8 or 4.12.5, see the release notes of version 4.12.5 for a list of earlier changes.

Known issues

  • Upgrading from 4.X Japanese version of the product (virusgw) to international version (fsigk) is not supported. Follow the instructions in the Administrator’s guide of the product to migrate settings from old (virusgw) installation to F-Secure Internet Gatekeeper (fsigk) installation.
  • Only the following printable ASCII characters are allowed in the credentials for accessing services using HTTP proxy (http_proxyauth_user and http_proxyauth_pass in fsigk.ini): letters, digits and the following special characters: -._~!$&'()*+,;=
  • If you use rpm to upgrade the product to the latest release, the product configuration files are reset to the factory defaults. The upgrade process renames the old configuration files by attaching an .rpmorig extension to the file name. This does not affect the main configuration file, fsigk.ini. As a workaround, you can rename the backup files back to their original names.
  • IE9: Placeholder texts for username and password in the Login screen are not displayed.
  • Using the High security level in the Internet Explorer security settings may prevent login to the Web UI due to javascript restrictions.
  • The product has limitations with HTTPS sites in the Web Content Control settings: https://community.f-secure.com/t5/Business/Limitations-with-HTTPS-sites-in/ta-p/79757
  • SELinux may prevent the log rotation. To solve this issue, set the appropriate security context to the log files after the product installation. Install policycoreutils-python package and run the following commands as root user:# yum install policycoreutils-python# semanage fcontext -a -t antivirus_log_t “/opt/f-secure/fsigk/log(/.*)?”# restorecon -Frv “/opt/f-secure/fsigk/log”
  • Symbolic links to sysvinit scripts in /etc/init.d/ have been removed when installing or upgrading in systemd environment. The services can be managed via corresponding init scripts in the installation directory: /opt/f-secure/fsigk/rc.fsigk_*.
  • The init script console output is now different compared to previous product releases when using systemd-enabled environment. The status (exit) code for starting, stopping and querying for service status remain the same as before.
  • ICAP daemon (fsicapd) may refuse to start in CentOS/RHEL 5 environments due to the default limit of available file descriptors a process may allocate (RLIMIT_NOFILE). Refer to Admin Guide chapter 4.5.1 for instructions how to configure a suitable limit.
  • Services may not start automatically when you upgrade the product from version 5.xx to 5.40 in systemd enabled operating systems: https://community.f-secure.com/t5/Business/Services-may-not-be/ta-p/88214
  • The System Information page of WebUI shows an incorrect product version after you upgrade to version 5.40. If Internet Gatepeer 5.30 hotfix 2 has been installed prior the upgrade, it will be shown for the new version as well. Run the following command as root user to resolve this issue:# rm -f /opt/f-secure/fsigk/log/hotfix.log
