Hello,

Generally a domain is a scope or realm, consisting of related contexts 
in which you define and operate your security components (depending on 
your security model) using a combination of:

SELinux  user, role, type and level (optionally, MLS sensitivity level)


Particularly, a domain is also used interchangeably with SELinux "type"

In addition, in RBAC (Role-based security model) to some extent a "role" 
can serve as an intermediary between domains (types) and be part of it.

Representations:

SELinux User :  SELinux Role :  SELinux Type :  Sensitivity Level
unconfined_u :  unconfined_r : unconfined_t  : s0-s0:c0.c1024


# ps -eZ
# ls -laZ




Best Regards,
