New features and changes

AntiSpam (formerly Spam Filter)

The FortiGuard-Web Filter menu contains the Override tab, Local Categories tab and Local Ratings tab. On FortiGate units with a hard disk, you can create reports from the Reports tab.

The Override tab provides administrators with flexibility and control when blocking web pages. Administrators can configure override rules that allow users to access blocked web pages, if required. Administrators can also create user-defined categories to allow users to block groups of URLs on a per-profile basis.

From the Local Ratings tab you can configure local ratings to specify whether the local rating is used in conjunction with the FortiGate rating or is used as an override. The Local Categories tab allows you to specify user-defined categories and then specify the URLs that belong to the category.

AntiSpam (formerly Spam Filter)

The Antispam menu consists of the following menus:

Banned word

Black/White list

You can configure additional features for FortiGate-800 units and above. In the

Banned word list you can:

create new antispam banned word list

view antispam banned word catalog

You can also configure the following for the FortiGate-800 and above in the

Black/White list:

add multiple email address lists

create new antispam email address list

create new antispam IP address list

view antispam IP address list catalog

The previous options available from the web-based manager in

FortiOS v2.80MR11, are now available in the CLI. See the FortiGate CLI Reference for more information. This includes FortiGuard AntiSpam, IP Address, DNSBL and ORDBL, MIME Headers, and Email Address.

If the MIME header check is enabled for POP3, IMAP or SMTP, and any change is made to the Protection Profile, such as IP address check, banned word check or logging oversized files (enabled through the web-based manager), the MIME header check is disabled.

Also, the “clear” action for banned words in an email is now available in the CLI to support upgrade. Since the “clear” action is no longer a valid spam action in FortiOS 3.0, avoid using it when configuring banned words.

Note: The Black/White lists are not separate. You may need to re-enable MIME Headers when you upgrade to FortiOS 3.0.

Customizable alerts and reports empower IT teams to remain vigilant and responsive to any irregularities or breaches in security.

Moreover, FortiOS 3.0 leverages Fortinet's proprietary security processor technology, which accelerates threat processing and reduces latency. This hardware acceleration ensures that even in high-volume traffic situations, security measures do not compromise network speed.

In summary, Fortinet FortiOS 3.0 stands out due to its comprehensive security features, unified threat management capabilities, advanced VPN functionalities, and robust logging and reporting tools.
