Security Portal: Linux Viruses: Scanner Placement

"A virus scanner doesn't do you any good if it's not somewhere along the path the virus takes to get into your network, onto your machine, and then executed. When deploying antivirus software, there are a number of factors to consider...."

"Antivirus software should be loaded onto workstations when possible, especially for mobile users with laptops. Consideration should also be given to purchasing antivirus software for people that telecommute from home. Even if you do not load antivirus onto corporate desktops it is extremely important to load it onto users' home machines. The reason for this is that home machines will be accessing the Internet and are probably not protected by any form of antivirus software at the ISP's end."

"Another obvious place to filter for viruses is on your mailserver(s). Currently, email is one of the best infection vectors for viruses since the spread of a virus via email can take place in several hours and hit many thousands of email systems and hundreds of thousands if not millions of email clients. The majority of text based email clients for Linux are relatively secure, although pine has had some issues in thpast. GUI mailers such as Netscape support Java and JavaScript, making them vulnerable to email borne viruses. The language and scripting support in other mail clients varies."
