To be able to limit privileges of any process in the system a global bounding capability set is introduced and denoted as gB. gB has system wide effect and describes the maximum possible set of privileges any process can reach during its lifetime in the system. By no means can a process posses, in any of its capability sets (Subsection 4.2.7), a capability which is not in gB. Exactly how gB works can be seen in the Subsection 4.2.9.
