C1000-174: IBM WebSphere Application Server Network Deployment v9.0.5 Administrator

WebSphere Application Server uses Java policy files to grant Java 2 security permissions. IBM recommends using the JDK PolicyTool utility to update these files because it helps validate their syntax; malformed policy syntax can cause access-control failures. The app.policy file supplies default permissions for applications on a node, whereas application-specific additional permissions are normally defined in the application policy.
