• Make it possible to access DCE services from Java
applications obtained through Secure Web
• access DCE internal services (e.g. name service)
• access DCE application services (e.g. banking
service)
• Extend Java security by using DCE security
• enhance applet authentication
• a DCE aware Security Manager could grant the applet
