FAQ

Q: What is defense-in-depth strategy?A: Defense-in-depth strategy is an approach to cybersecurity that uses layers of defenses to protect industrial control systems.

Q: Why is defense-in-depth strategy important?A: It is important because it helps to mitigate the risks of cyber attacks and protect industrial control systems from unauthorized access or tampering.

Q: What are some common layers of defense in defense-in-depth strategy?A: Common layers of defense include network segmentation, firewalls, intrusion detection systems, access control, and encryption.

Q: How can defense-in-depth strategy be implemented in industrial control systems?A: It can be implemented by combining various security measures such as network segmentation, regular patching and updating, conducting cybersecurity training for employees, and implementing a robust incident response plan.

Q: What are the benefits of implementing defense-in-depth strategy?A: Benefits include increased resilience of industrial control systems, reduced risk of cyber attacks, and protection of critical infrastructure.

Q: What are some challenges in implementing defense-in-depth strategy?A: Challenges include the complexity of industrial control systems, the need for ongoing maintenance and updates, and ensuring coordination among different layers of defense.
