Archive scan depth

The antivirus scanner will open archives and scan the files inside. Archives within other archives, or nested archives, are also scanned to a default depth of twelve nestings. You can adjust the number of nested archives to which the FortiGate unit will scan with the uncompressed-nest-limit CLI command. Further, the limit is configured separately for each traffic type.

Configuring archive scan depth

For example, this CLI command sets the archive scan depth for SMTP traffic to 5. That is, archives within archives will be scanned five levels deep.

config firewall profile-protocol-options

edit “default”

config http

set uncompressed-nest-limit 5

end

You can set the nesting limit from 2 to 100.
