1.1 Overview

Malicious code, such as computer viruses, is one of the main threats for companies today. When users began to use office applications with macro capabilities to write documents and distribute them via mail and groupware servers, macro viruses started spreading rapidly.
After the millennium, the most common spreading mechanism has been the e-mail. Today about 90% of viruses arrive via e-mail. E-mails provide a very fast and efficient way for viruses to spread without any user intervention and this is why e-mail worm outbreaks, like Bagle, Sober and Mydoom, cause a lot of damage around the world.
The Internet is used by more and more people every day, which opens another, so far dormant channel, HTTP, for viruses to spread. F-Secure Anti-Virus Mail Server and Gateway products are designed to protect your company's mail and groupware servers and to shield the company network from any malicious code that travels in HTTP, FTP-over-HTTP or SMTP traffic. The protection can be implemented on the gateway level to screen all incoming and outgoing e-mail (SMTP), web surfing (HTTP) and file transfer (FTP) traffic. Furthermore, it can be implemented on the mail server level so that it not only protects inbound and outbound traffic but also internal mail traffic and public sources, such as Public Folders on Microsoft Exchange server s.
Providing the protection already on the gateway level has many advantages: the protection is easy and fast to set up and install, and it is invisible to the end users, which ensures that the system cannot be by-passed and is easy to maintain. Protecting the gateway level alone, however, is not enough to provide a complete antivirus solution; file server and workstation level protection is needed, too.

1.2 MIMEsweeper Product Family

Clearswift, manufacturer of the MIMEsweeper product family, provides complete content security solutions for email and Web traffic. With Clearswift MIMEsweeper for SMTP, the company is protected against every content-based email threat from spam to employee time-wasting, circulation of pornography, breaches in confidentiality , legal liability and IT resource misuse. Clearswift MIMEsweeper for Web does for web traffic what Clearswift MIMEsweeper for SMTP does for SMTP: analyzes every bit of traffic and removes every kind of content threat.
F-Secure integrates antivirus protection and disinfection with Clearswift MIMEsweeper for SMTP and MIMEsweeper for Web, creating a complete, integrated solution to detect and disinfect the Web- or e-mail-borne viruses already at the gateway level. F-Secure Anti-Virus for MIMEsweeper works together with the Clearswift products MIMEsweeper for SMTP and MIMEsweeper for Web.
F-Secure Anti-Virus for MIMEsweeper
F-Secure Anti-Virus for MIMEsweeper provides a powerful antivirus scanning solution that tightly integrates with Clearswift MIMEsweeper for SMTP and MIMEsweeper for Web products giving the corporation the powerful combination of complete content security.
CHAPTER 1 11
Introduction
There are three integration scenarios you can use with F-Secure Anti-Virus. First, the Content Scanner scenario provides the most effective integration and is the recommended way to set up the system. Second, the F-Secure Anti-Virus scenario provided by Clearswift integrates with the memory resident F-Secure Anti-Virus. Finally, when using the command line interface to F-Secure Anti-Virus, you can use the Virus Manager scenario provided by Clearswift. Although not as efficient a scenario as the other two presented above, in this scenario the antivirus scanner remains resident in memory, which means the command line does not reload the scanner every time.
A Content Scanner scenario needs to be created using the MIMEsweeper console. This scenario determines what is scanned for viruses and what happens if a virus is found. For configuring Content Scanner Scenario, see “
Configuring Content Scanner Scenario”, 25.
