Configuring a protection profile Firewall Protection Profile Antivirus options Figure 213:Protection profile antivirus options Note: NNTP options cannot be selected. Support will be added in the future. The following options are available for antivirus through the protection profile. Virus Scan File Pattern Quarantine (log disk required) Pass fragmented emails Comfort Clients Enable or disable virus scanning for each protocol (HTTP, FTP, IMAP, POP3, SMTP, IM). Grayware, if enabled in AntiVirus > Config > Grayware, is included with the Virus Scan. Heuristic, if enabled with the CLI, is also included with the Virus Scan. Note that streaming mode is enabled automatically when you enable virus scanning. Enable or disable file pattern processing for each protocol. Files can be blocked or allowed by name, extension, or any other pattern. File pattern processing provides the flexibility to block files that may contain harmful content. File pattern drop-down list: Select which file pattern list will be used with this protection profile. The default file pattern list is called builtinpatterns. Enable or disable quarantine for each protocol. Quarantine suspect files to view them or submit files to Fortinet for analysis. The quarantine option is not displayed in the protection profile if the FortiGate does not have a hard drive or a configured FortiAnalyzer unit. Enable or disable passing fragmented email for mail protocols (IMAP, POP3, SMTP). Fragmented email cannot be scanned for viruses. Enable or disable client comforting for HTTP and FTP traffic. Client comforting provides a visual status for files that are being buffered for downloads using HTTP and FTP. Users can observe web pages being drawn or file downloads progressing. If disabled, users have no indication the FortiGate unit is buffering the download and they may cancel the transfer thinking it has failed. Interval Amount The time in seconds before client comforting starts after the download has begun. It is also the time between subsequent intervals. The number of bytes sent at each interval.

Firewall Protection Profile Configuring a protection profile Oversized File/Email Add signature to outgoing emails Web filtering options Select block or pass for files and email messages exceeding configured thresholds for each protocol. Threshold See “AntiVirus” on page 397 for more antivirus configuration options. Figure 214:Protection profile web filtering options If the file is larger than the threshold value in megabytes, the file is passed or blocked, as set in the Oversized File/Email drop down. The maximum threshold for scanning in memory is 10% of the FortiGate unit RAM. Note: For email scanning, the oversize threshold refers to the final size of the email after encoding by the email client, including attachments. Email clients may use a variety of encoding types and some encoding types translate into larger file sizes than the original attachment. The most common encoding, base64, translates 3 bytes of binary data into 4 bytes of base64 data. So a file may be blocked or logged as oversized even if the attachment is several megabytes smaller than the configured oversize threshold. Create and enable a signature to append to outgoing email (SMTP only). The following options are available for web filtering through the protection profile. Web Content Block Web Content Exempt Web URL Filter ActiveX Filter Cookie Filter Java Applet Filter Enable or disable web page blocking for HTTP traffic based on the content block patterns in the content block list. Web content block drop-down list: Select which content block list will be used with this protection profile. Threshold: If the combined scores of the content block patterns appearing on a web page exceed the threshold value, the page will be blocked. See “Viewing the web content block list” on page 427 for details. Enable or disable the override of web content block based on the content exempt patterns in the content exempt list. Web content exempt drop-down list: Select which content exempt list will be used with this protection profile. Enable or disable web page filtering for HTTP and HTTPS traffic based on the URL list. Web URL filter drop-down list: Select which web URL filter list will be used with this protection profile. Enable blocking of ActiveX controls. Enable blocking of cookies. Enable blocking of Java applets. FortiGate Version 3.0 MR5 Administration Guide 01-30005-0203-20070830 333
