Web application protection provides different levels of protection policies, including loose, normal, and strict, to prevent common Web application attacks such as SQL injection and XSS attacks.
After you add your domain to the WAF protection list, you can enable Web application protection for this domain, and select a protection policy. This feature takes effect immediately after you enable it. You can disable it at any time.
Before you perform the following operations, make sure that you have added the domain to WAF for protection. For more information, see Use WAF CNAME to add domains for protection.
- Log on to the WAF console.
- In the left-side navigation pane, choose . On the Website Configuration page, select the region of your WAF instance. The options include Mainland China and International.
- In the domain list, find the domain to be configured, and click Policies in the Operation column.
- Enable Web Application Protection, and select a mode.
Note You can disable this feature on this page.
- Prevention mode: detects and blocks attacks.
- Detection mode: detects attacks and generates alerts.
- In the Policy drop-down list, select a protection policy.
- By default, the Normal policy is selected.
- In the normal policy mode, if many normal requests are blocked or many uncontrollable user inputs are detected, such as rich text editors and technology forums, we recommend that you use the Loose policy.
- If you require stricter protection against path traversal, SQL injections, and command execution attacks, we recommend that you use the Strict policy.
- Click Settings on the right of Decoding Settings. In the Decoding Settings dialog box, select the data formats to be decoded and analyzed by the Web application
protection feature. If this feature often blocks normal requests with data of a specific
format, open the Decoding Settings dialog box, clear the check box of this format, and click OK.
