Edition
When editing a security domain, you may specify
- the code: it must be unique
- the name of the security domain
- the domain class; this is used to mark the domain to be evaluated under specific security profiles; the classes depend on the configuration
- one or more sources of information
- a longer description
The description may include hyperlinks (URLs). To go to the linked page RIGHT-CLICK, then 

Sources control the write access to elements in the domain: assets, safeguards and controls.
A domain may be labelled with one or more classes. The set of available classes is determined by configuration. Most classes lack any semantics; it is just a mark to filter domains.
