Foil 69 JAVA Fine-grained Access Control-5

From Remarks on Internet and Java Security Basic Information Track Computational Science Course CPS616 -- Spring Semester 1999. by Geoffrey Fox, Mehmet Sen
The AccessController checkPermission algorithm is as follows:
  • If the code for any caller in the call chain does not have the requested permission, AccessControlException is thrown, unless the following is true - a caller whose code is granted the said permission has been marked as "privileged" and all parties subsequently called by this caller (directly or indirectly) all have the said permission.
