Information Labels

Information labels (ILs) are not supported in Trusted Solaris 7 and later releases. Trusted Solaris software interprets any ILs on communications and files from systems running earlier releases as ADMIN_LOW.

Objects still have CMW labels, and CMW labels still include the IL component: IL[SL]; however, the IL component is fixed at ADMIN_LOW.

As a result, Trusted Solaris 7 has the following characteristics:

• ILs do not display in window labels; SLs (Sensitivity Labels) display alone within brackets.

• ILs do not float.

• Setting an IL on an object has no effect, and getting an object's IL will always return ADMIN_LOW.

• Although certain utilities, library functions, and system calls can manipulate IL strings, the resulting ILs cannot be set on any objects.

• Sensitivity labels, not information labels, display on printer banners and body pages.

• Options related to information labels in the label_encodings(4) file can be ignored.

• IL-related privileges are no longer used. See "Authorization and Privilege Differences" for a list.

• In auditing, the ilabel token is recorded as ADMIN_LOW, when it is recorded. The audit event numbers 519 (AUE_OFLOAT), 520 (AUE_SFLOAT), and 9036 (AUE_iil_change) continue to be reserved, but those events are no longer recorded.
