Question 42
Which of the following is a key difference between IT and ICS cybersecurity?
- A IT focuses on physical security
- B ICS focuses on data integrity
- C ICS has a higher tolerance for downtime
- D ICS prioritizes availability and safety
Reveal correct answer
Correct answer: D
Explanation
Prioritizing availability and safety is a key difference between IT and ICS cybersecurity. Unlike traditional IT systems where data confidentiality, integrity, and availability are the primary focus, IACS are responsible for controlling and monitoring physical processes in industrial environments, where safety and availaibility is paramount. Therefore, cybersecurity measures for IACS must not only safeguard against cyber threats but also ensure the safety and reliability of industrial operations. Similarly, in ICS environments, maintaining system uptime and ensuring control systems are continuously operational is paramount. Disruptions to critical processes due to cyberattacks can have severe consequences for safety, production, and the environment.Discussion
