Wajih,

Blocking Port Scanning is a network rule set and options will depend on how FortiWeb is deployed. The best option would be to place a FortiGate in front of the environment, but FortiWeb does have a basic firewall integrated that can be used to block any used data ports. The FWB network firewall is just not as robust or have the same rules options you would have on a true network firewall like a FortiGate. NOTE: FWB network Firewall is a newer feature, so your customer may need to perform a firmware upgrade if this option is not showing up as available. Help reference to this setting option: http://help.fortinet.com/fweb/570/index.htm#cshid=firewall_service

Blocking a port scans would be an option on a gateway firewall to help prevent a source from scanning a single IP or network range probing to seeing which services are running within that target IP/network. After the run a port scan they often follow up with a service probe to see what is running on the identified running services. I suspect you are talking about blocking this second phase where the WAF blocks a source from scanning a web service. The behaviors like spiders/crawlers can be identified and blocked using the FortiWeb the Advanced Rules. They match on multiple conditions and then take an action. There are some predefined polices that you can use or clone to customized. These rules are very flexible and should meet your match condition requirements.
