User-defined profiles are profiles that are build and configured by users. Unlike the default profiles, you must configure a user-defined profile before it will be of use filtering traffic to and from your protected applications.
There are three types of user-defined profile:
- HTML. Protects HTML-based web pages.
- XML. Protects XML-based web services and web sites.
- Web 2.0. Protects Web 2.0 content that combines HTML and XML content, such as ATOM feeds, blogs, and RSS feeds.
The application firewall has a number of security checks, all of which can be enabled or disabled, and configured in a number of ways in each profile. Each profile also has a number of settings that control how it handles different types of content. Finally, rather than manually configuring all of the security checks, you can enable and configure the learning feature. This feature observes normal traffic to your protected web sites for a period of time, and uses those observations to provide you with a tailored list of recommended exceptions (relaxations) to some security checks, and additional rules for other security checks.
During initial configuration, whether by using the Application Firewall Wizard or manually, you normally create one general purpose profile to protect all content on your web sites that is not covered by a more specific profile. After that, you can create as many specific profiles as you want to protect more specialized content.
The Profiles pane consists of a table that contains the following elements:
Name. Displays all the application firewall profiles configured in the appliance.
Bound signature. Displays the signatures object that is bound to the profile in the previous column, if any.
Policies. Displays the application firewall policy that invokes the profile in the leftmost column of that row, if any.
Comments. Displays the comment associated with the profile in the leftmost column of that row, if any.
Profile Type. Displays the type of profile. Types are Built-In, HTML, XML, and Web 2.0.
Above the table is a row of buttons and a drop-down list that allow you to create, configure, delete, and view information about your profiles:
- Add. Add a new profile to the list.
- Edit. Edit the selected profile.
- Delete. Delete the selected profile from the list.
- Statistics. View the statistics for the selected profile.
- Action. Drop-down list that contains additional commands. Currently allows you to import a profile that was exported from another application firewall configuration.
