The nation's critical physical infrastructure depends crucially on
SCADA (Supervisory Control and Data Acquisition) and DCS (Digital
Control Systems). Power networks, oil, gas, and water networks,
chemical process control, transportation networks, the heating,
ventilation and air conditioning systems of buildings depend
critically on the sensing, monitoring, gathering, and control of
information from distributed sensing devices. It is clear that these
devices have been deployed in ad-hoc fashion in our infrastructures
and are widely used in a number of different kinds of applications
including economic load dispatch, security monitoring, regulation of
climate and other such functions. As our use of ubiquitous computing
and communication devices has increased, we have gradually built
greater functionality into our SCADA/DCS systems. The by-product of
these technological advances has been a lack of planned deployment of
what we may refer to as high confidence devices and software. These
are Devices and Networked Systems that are:
Correct by construction and which can be reprogrammed on the fly
based on the functionality that is expected of them.
Fault tolerant, such that they are able to resist catastrophic
failure under certain kinds of faults and mis-configurations and are
able to reconfigure themselves to degrade gracefully under faulty
conditions.
Resistant to information attack, such that they have
defense-in-depth features which allow them to resist attack by
determined hackers, hacktivisits, and possibly even nation-states.
