Nearly all forms and types of ICS infrastructure could become victims to types of cyber attacks because of the replacement of traditional electro mechanical logic controllers of control systems with embedded operating systems and microprocessor devices.
The use of internet working technologies, adoption of commercial off-the-shelf(COTS) equipment, open designs, standards and technologies, increasing size and functionality of systems, increasing dependency on IT workforce, lack of personnel training and updates in security, change management, necessities for continuous operations that preclude changes or upgrades, use of legacy systems with low memory or processing power that refute strong security mechanisms among others.
Threatagents could include: attackers, bot-network operators, criminal groups, foreign intelligence services, insiders phishers, spammers, spyware/malware authors, terrorists, andindustrial spies.
