As presented at AIST 2014: The proliferation of cyber threats and recent facts have prompted asset owners in industrial environments to search for security solutions that can protect plant assets and prevent potentially significant monetary loss and safety issues
While some industries have made progress in reducing the risk of cyber attacks, the barriers to improving cybersecurity remain high. More open architectures and different networks exchanging data among different levels have made systems more vulnerable to attack.
With the increased use of commercial off-the-shelf IT solutions in industrial environments, control system integrity started to be vulnerable to malware originally targeted for commercial applications and already opened a new world of new threats dedicated for control systems.
The objective of this presentation is to describe a multi-layered Defense-in-Depth approach through a holistic, step-by-step plan to mitigate risk.
