Worm protection for incoming connections
When configured for worm scanning, the virus scanning engine checks HTTP requests for worms by
scanning their originating web page for known worm patterns. For example, Code Red attempts to gain
entry to MS IIS servers by trying to exploit a known buffer overflow bug in these servers.
To scan SMTP, POP3, and IMAP email attachments for worms, the virus scanning engine looks for
filenames known to be used by worms. For example, the Nimda worm uses files named readme.exe and
sample.exe.
If the virus scanning engine detects a worm, the file is deleted and replaced with an alert message.
To prevent the distribution of worms from servers on your internal and DMZ networks to the Internet:
•
Go to Anti-Virus > HTTP > Incoming.
•
Click Worm Protection to scan content from web servers on your internal or DMZ network for worms
before that content passes through the firewall.
•
