Advanced configuration

•Grayware - These are unsolicited commercial software programs that are installed on computers, often without the user's consent or knowledge. Grayware programs are generally considered an annoyance, but these programs can cause system performance problems or be used for malicious ends. The FortiGate unit scans for known grayware executable programs in each enabled category.

•Heuristics - The FortiGate heuristic antivirus engine performs tests on the file to detect virus-like behavior or known virus indicators. In this way, heuristic scanning may detect new viruses, but may also produce some false positive results.

The antivirus elements work in sequence to give you an efficient method of scanning incoming files. The first three elements have specific functions, the fourth, the heuristics, is to cover any new previously unknown virus threats. The four elements work together to offer your network unparalleled antivirus protection. To ensure that your system is providing the most protection available, all virus definitions and signatures are up dated regularly through the FortiGuard antivirus services.

To configure the file patterns that the FortiGate scans, go to AntiVirus > File Filter.

To enable grayware blocking, go to AntiVirus > Config > Grayware.

Antivirus settings are turned on in the protection profile. In the protection profile you can enable antivirus options for specific services and which services will use the file patterns as a part of the antivirus process.

To configure antivirus protection profile settings, go to Firewall > Protection Profile. Select edit for a profile and select the Anti-Virus options.

For details on the antivirus features and settings, see the FortiGate Administration Guide or the FortiGate Online Help.

The FortiGate unit’s antispam feature detects unsolicited commercial email by identifying spam email messages and spam transmissions from known or suspected spam servers.

This feature requires a FortiGuard subscription and a registered FortiGate unit. When the FortiGate unit receives an email message, it verifies with the FortiGuard server whether it is a valid email or a spam message. FortiGuard Antispam is one of the features designed to manage spam. FortiGuard is an antispam system from Fortinet that includes an IP address black list, a URL black list, and spam filtering tools. The FortiGuard Center accepts submission of spam email messages as well as well as reports of false positives.

Depending on how you configure the FortiGate unit, the FortiGate unit will either tag the message with text so you can easily identify the spam, or delete the message before it reaches the recipient.

The FortiGate unit also enables you to create your own spam filters using banned words and black/white lists.
