All the advantages of digitization have not been without some drawbacks. In the industrial sector specifically, productivity and availability issues have multiplied. As industrial control systems (ICS) increasingly rely on information systems to perform production, scheduling, and remote access operations, interconnecting ICS systems has taken a toll on security.
Risks that were once only encountered on information systems have now crossed over and begun to contaminate industrial systems. Included among these risks are the various vulnerabilities associated with access to supervisory control and data acquisition (SCADA) systems as well as the actions performed on them. In particular, privileged user access exposes these systems to sizable vulnerabilities with the potential to strike a direct blow to the availability and operation of industrial systems.
