Configuring Web Tamper Protection Rules¶
This section describes how to configure web tamper protection (WTP) rules.
You can configure these rules to prevent a static web page from being tampered with.
WTP has the following advantages:
Quicker response to requests
After a WTP rule is configured, WAF caches the static web page on the server. When receiving a request from a web visitor, WAF returns the cached page to the visitor.
Web tamper protection
If an attacker modifies a static web page on the server, WAF returns the cached original web page to web visitors, ensuring that visitors never access tampered-with pages.
WAF can randomly extract a request from a web visitor to compare the requested page with the web page on the server. If WAF detects that the page has been tampered with, it notifies the user by SMS or email. For details about alarm notification settings, see Enabling Alarm Notification.

Note
The path does not support regular expressions.
The path cannot contain two or more consecutive slashes. For example, ///admin. If you enter ///admin, the WAF engine converts /// to /.
