Configuring Web and Services Protection
The STM lets you configure the following settings to protect the network’s Internet
communication:
•
The Web protocols that will be scanned for malware.
•
Actions that will be taken when infected Web files or objects are detected.
•
The maximum file sizes that will be scanned.
•
Web objects that will be blocked.
•
Web categories, keywords, and file types that will be filtered to block objectionable or high-
risk content.
•
Domains and URLs that will be blocked for objectionable or high-risk content.
•
Customer notifications and e-mail alerts that will be sent when events are detected.
•
Schedules that determine when content filtering will be 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, only enable scanning 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
“Performance Management” on page 3-32
.
To specify the Web protocols and ports that will be scanned for malware.
