Configuring Web and Services Protection

The STM lets you configure the following settings to protect the network's Internet
communication:
• The Web protocols that are scanned for malware threats
• Actions that are taken when infected Web files or objects are detected
• The maximum file sizes that are scanned
• Web objects that are blocked
• Web categories, keywords, and file types that are filtered to block objectionable or
high-risk content
• Domains and URLs that are blocked for objectionable or high-risk content
• Customer notifications and email alerts that are sent when events are detected
• Schedules that determine when content filtering is active

Customizing Web Protocol Scan Settings

If you have used the Setup Wizard, you might have already configured the Web protocol
scan settings; the (Web) Policy screen allows you to modify these settings.
Scanning all protocols enhances network security, but might affect the performance of the
STM. For an optimum balance between security and performance, enable scanning only of
the most commonly used protocols on your network. For example, you can scan FTP and
HTTP, but not HTTPS (if this last protocol is not often used). For more information about
performance, see
