The IEEE POSIX.1e specification never left draft form, but the interfaces

POSIX.1e assigns security labels to all objects, extending the security
functionality described in POSIX.1. These additional labels provide
functionality described in POSIX.1.
These additional labels provide
fine-grained discretionary access control, fine-grained capabilities,
