> Compatibility security refers to the capability to run security configurations from WebLogic Server 6.x in this version of WebLogic Server. In Compatibility security, you configure 6.x security realms, define users, groups, and ACLs, manage the protection of user accounts, and install custom auditing providers. The only security realm available in Compatibility security is the CompatibilityRealm. This page allows you to define the general configuration of the CompatibilityRealm for this WebLogic Server domain.

> The Auditing provider installed from this page must be an implementation of the `weblogic.security.audit` interface. This interface is deprecated in this release of WebLogic Server. The `guest` user is automatically provided in Compatibility security. When authorization is not required, WebLogic Server assigns the `guest` identity to an client, thus giving the client access to any resources that are available to the `guest` user. A client can log in as the `guest` user by entering `guest` as the username and password when prompted by a Web browser or in a Java client. By default, the `guest` account is disabled. For a more secure deployment, Oracle recommends running WebLogic Server with the `guest` account disabled.
