ProSecure Unified Threat Management (UTM) Appliance Reference Manual Table 6-7. Malware Scan Settings (continued) Setting Description (or Subfield and Description) Scan Exception The default maximum file or object size that are scanned is 2048 KB, but you can define a maximum size of up to 10240 KB. However, setting the maximum size to a high value might affect the UTM's performance (see "Performance Management" on page 10-1). From the pull-down menu, specify one of the following actions when the file or message exceeds the maximum size: • Skip. The file is not scanned but skipped, leaving the end user vulnerable. This is the default setting. • Block. The file is blocked and does reach the end user. HTML Scan Scan HTML elect this checkbox to enable scanning of HyperText Markup Language (HTML) files, Files which is enabled by default. Notification Settings By default, the content of a Web page that is blocked because of a detected malware threat is replaced with the following text, which you can customize: NETGEAR ProSecure UTM has detected and stopped malicious code embedded in this web site or web mail, for protecting your computer and network from infection. %VIRUSINFO%" Note: Make sure that you keep the %VIRUSINFO% meta word in a message to enable the UTM to insert the proper malware information. In addition to the %VIRUSINFO% meta word, you can insert the following meta words in your customized message: %TIME%, %PROTOCOL%, %FROM%, %TO%, %SUBJECT%, %FILENAME%, %ACTION%, %VIRUSNAME%. 3. Click Apply to save your settings. Configuring Web Content Filtering If you want to restrict internal LAN users from access to certain types of information and objects on the Internet, use the UTM's content filtering and Web objects filtering. With the exception of the Web content categories that are mentioned in "Default E-mail and Web Scan Settings" on page 6-2, all requested traffic from any Web site is allowed. You can specify a message such as "Blocked by NETGEAR" that is displayed on screen if a LAN user attempts to access a blocked site (see the Notification Settings section that is described at the bottom of Table 6-8 on page 6-28).
