Application Profile Rules

On the Rules tab you may review and change the rules for handling requests enabled for the current application profile.

The application profile is a collection of known information about protected applications. It is used to fine-tune the behavior of the system during the analysis of requests and their further processing in the post-analysis module as well as in the cloud.

For a better understanding of how the traffic processing rules are applied, it is advisable to learn how the filter node analyzes the requests.

One important thing about making changes to the rules is that these changes don't take effect immediately. It may take some time to compile the rules and download them into filter nodes.

Terminology

Point

Each parameter of the HTTP request in the Wallarm system is described with a sequence of filters applied for request processing, e.g., headers, body, URL, Base64, etc. This sequence is called the point.

Request processing filters are also called parsers.

Rule Branch

The set of HTTP request parameters and their conditions is called the branch. If the conditions are fulfilled, the rules related to this branch will be applied.

For example, the rule branch example.com/**/*.* describes the conditions matching all requests to any URL of the domain example.com.

Endpoint (Endpoint Branch)

A branch without nested rule branches is called an endpoint branch. Ideally, an application endpoint corresponds to one business function of the protected application. For instance, such business function as authorization can be an endpoint rule branch of example.com/login.php.

Rule

A request processing setting for the filter node, the post-analysis module, or the cloud is called a rule.

Processing rules are linked to the branches or endpoints. A rule is applied to a request only if the request matches all the conditions described in the branch.
