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 12-26.

Selecting the classification window and pressing the ESC key
will temporarily hide the window for 15 seconds, it will return
to view after that

These are examples for the configuration of the Classification Banner
using the '/etc/classification-banner' file for various classifications
based upon generally accepted color guidelines in the DoD/IC.
