Classification-Banner
=====================
Classification Banner is a python script that will display the
classification level banner of a session with a variety of
configuration options on the primary screen. This script can
help government and possibly private customers display a
notification that sensitive material is being displayed - for
example PII or SECRET Material being processed in a graphical
session. The script has been tested on a variety of graphical
environments such as GNOME2, GNOME3, KDE, twm, icewm, and Cinnamon.
Python script verified working on RHEL 5/6/7 and Fedora 12-22.
Selecting the classification window and pressing the ESC key
will temporarily hide the window for 15 seconds, it will return
to view after that
