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. They provide outstanding protection level and fast, automatic updates to the scanning engines and anti-virus databases. With F-Secure’s Real-Time Protection Network, 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.

New features

This release contains the following new features, bug fixes and other changes that have been added since the 5.00.5 release.

  • ICAP service supports scanning emails for malware and spam.
  • A new and improved web user interface has been added.
  • A new quick start guide has been added for easy installation and usage instructions.
  • Fixed CTS-82476: fsaua now restarts automatically when user changes the virus database download proxy settings from the web user interface.
  • Fixed CTS-84901: FmLib library version is not visible in the web user interface.
  • Fixed CTS-86302: Added documentation for configuring the HTTP proxy for anti-spam daemon (fsasd) in the administrator guide.
  • Fixed CTS-91777: Fixed detecting malicious javascript and html files.
  • Fixed CTS-91852: Added missing information for ICAP detections templates in administrator guide.
  • Fixed CTS-91867: Improved the documentation for the transparent proxy bridge mode using subnet in the administrator guide.
  • Fixed CTS-92431: Improved the detection rate for policy-based blocking for javascripts and ActiveX scripts.
  • Fixed CTS-92216: Fix timeout_inactive for web servers that take more time than keepalive_timeout to start sending the reponse to IGK.
  • Fixed CTS-92759: Fixed the log size specification of logconv tool in the administrator guide.
  • Fixed CTS-92797: Fixed information for the scanning daemon (fsavd) process management in the administrator guide.
  • Fixed CTS-92814: Parsing a very large email header can lead to a false detection or other unexpected result.
  • Fixed CTS-92861: IGK fails to detect too long HTTP request URL.
  • Fixed CTS-93579: Fixed information about connection error messages in the administrator guide.
  • Fixed CTS-94390: Added missing system requirements and dependencies in the IGK release notes.
  • Fixed CTS-94834: Added information about orsp_file_check for the HTTP proxy in the administrator guide.

This release contains the following new features, bugfixes and other changes that have been added since the 4.10.17 release.

  • Support for F-Secure Real-Time Protection Network has been added to the HTTP proxy. When enabled, common files are identified by rapidly updating black and white lists. This saves system resources and improves 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. The 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. The 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.
