Configuring medium level virus protection for your internal network
Medium level protection scans all target files for viruses. You can configure the DFL-1000 to perform up
to four different types of virus scans on each target file:
•
Signature scanning
•
Macro scanning
•
Behavior (simulated execution)
•
Heuristic scanning
If a virus is found in a file, the virus scanner deletes the file and replaces it with an alert message that is
forwarded to the user. If a virus is not found, the file is forwarded unchanged to the user.
Medium level virus scanning prevents known viruses from entering your internal network while still
allowing virus-free HTTP downloads and email attachments to pass through the firewall.
To protect your internal network with medium level virus protection:
•
Go to Anti-Virus > SMTP > Outgoing.
•
Click Medium to virus scan target files in email attachments in SMTP traffic.
•
Click Detail and select the types of scanning to use:
Signature
Scan the target file for byte-strings that identify known viruses.
