Introduction
1.2 How the Product Works
F-Secure Internet Gatekeeper is a suite of real-time services to protect
the corporate network against computer viruses and malicious code
coming in web (HTTP and FTP-over-HTTP) and e-mail (SMTP) traffic.
F-Secure Internet Gatekeeper is comprised of the following
components: F-Secure Anti-Virus for Internet Gateways , F-Secure
Anti-Virus for Internet Mail and F-Secure Content Scanner Server .
1.2.1 F-Secure Anti-Virus for Internet Gateways
F-Secure Anti-Virus for Internet Gateways is an HTTP proxy server which
acts as a gateway between the corporate network and the Internet. If a
client computer requests a file from a Web server, it asks the proxy server
to retrieve the file instead of downloading it directly from the Internet.
F-Secure Anti-Virus for Internet Gateways processes the request to make
sure that the content does not contain any malicious code and it should
not be blocked. F-Secure Anti-Virus for Internet Gateways returns only
allowed Web content and virus-free files to the requesting client. All files
and web pages downloaded via HTTP and FTP-over-HTTP are checked
for viruses and malicious code on the fly.
