  Cyber attacks have become serious threats to Industrial Control systems as
well. It becomes important to develop a serious threat defense system against
such vulnerabilities. For such process control systems, safety should also be
assured apart from security. As unearthing vulnerabilities and patching them is
not a feasible solution, these critical infrastructures need safeguards to
prevent accidents, both natural and artificial, that could potentially be
hazardous. Morita proposed an effective Zone division, capable of evaluating
remote and concealed attacks on the system, coupled with Principal Component
Analysis. But the need to analyze the node that has been compromised and
stopping any further damages, requires an automated technique. Illustrating the
basic ideas we'll simulate a simple Water plant. We propose a new automated
approach based on Long Short Term Memory networks capable of detecting attacks
and pin point the location of the breach.
