ProSecure Unified Threat Management UTM10 or UTM25 Reference Manual

Configuring Web and Services Protection

The UTM lets you configure the following settings to protect the network’s Internet and Web services communication:

•The Web protocols, instant messaging services, and peer-to-peer services 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 e-mail alerts that are sent when events are detected.

•Schedules that determine when content filtering is active.

Customizing Web Protocol Scan Settings and Services

You can specify the Web protocols (HTTP, HTTPS, and FTP) that are scanned for malware threats and the instant messaging and peer-to-peerapplications that are allowed or blocked.

Scanning all protocols enhances network security, but might affect the performance of the UTM. 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 10-1.

To configure the Web protocols, ports, and applications to scan:

1.Select Application Security > Services from the menu. The Services screen displays (see Table 6-7 on page 6-20).

Note: For information about e-mail protocols and ports, see “Customizing E-mail Protocol Scan Settings” on page 6-4.
