The threat to critical infrastructure
Supervisory control and data acquisition (SCADA) and industrial control systems (ICS) are cornerstone critical infrastructure solutions. SCADA networks were designed to deliver robust performance, reliability, flexibility, and safety of distributed control, with less attention paid to critical infrastructure cybersecurity. SCADA networks are vulnerable to disruption of service, process redirection or manipulation of operational data. A cyber-attack could result in public safety concerns or serious disruptions to the critical infrastructure of a nation or enterprise.
In critical infrastructure solutions, particularly the energy sector, increased incidences of advanced persistent threats (APTs) have been reported. To add to the problem, detection of a compromise is difficult. Hackers could access a system and operate disguised as a trusted employee for long periods of time without appropriate network security implementations.
