SecurityPolicySection Class

Defines configuration settings that are used to support the security infrastructure of a Web application. This class cannot be inherited.

Namespace: System.Web.Configuration
Assembly: System.Web (in system.web.dll)

public sealed class SecurityPolicySection : ConfigurationSection
public final class SecurityPolicySection extends ConfigurationSection
public final class SecurityPolicySection extends ConfigurationSection
Not applicable.

The SecurityPolicySection class provides a way to programmatically access and modify the content of the securityPolicy section of the configuration file.

This example demonstrates how to specify values declaratively within the securityPolicy section, which can also be accessed as members of the SecurityPolicySection class.

The following configuration file example shows how to specify values declaratively for the securityPolicy section.

<system.web>
  <securityPolicy>
    <trustLevel name="Full" policyFile="internal" />
    <trustLevel name="High" policyFile="web_hightrust.config" />
    <trustLevel name="Medium" policyFile="web_mediumtrust.config" />
    <trustLevel name="Low" policyFile="web_lowtrust.config" />
    <trustLevel name="Minimal" policyFile="web_minimaltrust.config" />
  </securityPolicy>
</system.web>

The following code example demonstrates how to use the SecurityPolicySection class.
