In [[Object-capability model|capability-based computer security]], a '''C-list''' is an [[array (data structure)|array]] of capabilities, usually associated with a [[process (computing)|process]] and maintained by the [[kernel (computeroperating sciencesystem)|kernel]]. The program running in the process does not manipulate capabilities directly, but refers to them via '''C-list indexes'''—integers indexing into the C-list.

The [[file descriptor|file descriptor table]] in [[Unix]] is an example of a C-list. Unix processes do not manipulate [[file descriptor]]s directly, but refer to them via file descriptor numbers, which are C-list indexes.

In the [[KeyKOS]] and [[ExtremelyEROS Reliable Operating System(microkernel)|EROS]] operating systems, a process's capability registers constitute a C-list.<ref>{{cite web|url=http://www.cap-lore.com/CapTheory/Glossary.html |title=Glossary |publisher=Cap-lore.com |date=2000-01-19 |accessdate=2019-07-08}}</ref>
