Companies looking to protect an industrial control system (ICS) should audit their assets, network, and data flows to better determine how safe a system is, and what more needs to be done.
The threat landscape for industrial automation and Industrial Internet of Things (IIoT) systems is evolving as connectivity between disparate devices and networks grows. It is crucial that organizations plan and execute effective defense-in-depth (DID) strategies and invest in the continued evaluation and adjustment of their security measures.
According to Symantec's 2018 Internet Security Threat Report, there's been a 29% increase in industrial control system (ICS) related vulnerabilities over the past year. Given the valuable and safety-critical processes these systems connect and control, security breaches can have expensive, widereaching and dangerous implications.
Malicious ICS attacks can include loss of view, manipulated view, denial of control, manipulation of control, and loss of control. Consequences can include interruption to dangerous failures and extended outages.
