> This page lists displays key information about each ACL that has been configured in this security realm (CompatibilityRealm). This page applies only to WebLogic Server deployments using Compatibility security.

> Users access resources in a WebLogic Server security realm. Whether or not a user can access a WebLogic resource is determined by the access control lists (ACLs) for that WebLogic resource. An ACL defines the permissions by which a user can interact with the WebLogic resource. To define ACLs, you create an ACL for a WebLogic resource, specify the permission for the WebLogic resource and then grant the permission to a specified set of users and groups. Oracle recommends assigning ACLs to groups.
