# Edit Web Application/API Settings

Configuring [Web Application / API](https://waf-doc.inext.checkpoint.com/getting-started/protect-a-web-api) is easily done via the configuration wizard, and in the vast majority of the cases, is enough to fully protect the web assets without additional manual changes.

There are, however, advanced options that a security administrator can configure to modify the security to his specific requirements.

When making the first change to the default Web Application Best Practice's configuration such as configuring the advanced settings in this page, you will be prompted to change the name of the Practice to your own custom practice name.

### Configuration Options

#### Mode override

Setting the Mode to **As Top Level** means inheriting the primary mode of the practice.

Otherwise you can override it only for this specific sub-practice to **Detect**/**Prevent**/**Disable**.

#### Confidence-dependent Prevent Mode

The option **Activate when confidence is** becomes available if practice or sub-practice are set to **Prevent**. The value determines the threshold in which CloudGuard WAF will block attacks and prevent them, rather than just send a log according to Log Trigger configuration.

For all Size Limits - CloudGuard WAF Web Attacks engine will accept traffic that exceeds the limits if set to **Detect/Learn** mode (and that traffic will bypass inspection), or block traffic that exceeds the limits if set to **Prevent** mode.

## Web API Protection Advanced Settings

The advanced configuration for API Attacks is very similar to Web Attacks.\
The differences being:

* The sub-practice is named **API Attacks** and not Web **Attacks**.
* API attacks do not include the advanced options of CSRF Protection, Error Disclosure and Open Redirect.
* See here how to configure the [**API Schema Enforcement Engine**](https://waf-doc.inext.checkpoint.com/additional-security-engines/api-protection/enforce-api-schema)

## Additional Security Engines

CloudGuard WAF includes additional security engines other in addition to the Machine Learning based-Web Attacks protection and API attacks protection:
