What are the three main phases of the IACS Cybersecurity Lifecycle?

The three main phases of the IACS (Industrial Automation and Control Systems) Cybersecurity Lifecycle are correctly identified as Assess, Develop and Implement, and Maintain. This framework is crucial for establishing and ensuring effective cybersecurity measures within industrial control systems.

In the Assess phase, organizations evaluate their current cybersecurity posture, identifying vulnerabilities and risks associated with their systems. This thorough examination is critical for understanding the existing security landscape and the specific threats faced.

Next, the Develop and Implement phase focuses on creating a robust cybersecurity strategy based on the findings from the assessment. This includes designing security policies, implementing protective measures, and ensuring that the technical components of the system are secure against identified threats. This proactive step is essential for mitigating risks and enhancing the resilience of the IACS.

Finally, the Maintain phase involves ongoing monitoring and management of the cybersecurity measures already in place. This phase ensures that the systems continue to function securely and that any new threats or vulnerabilities are addressed promptly. Continuous maintenance is vital for sustaining the effectiveness of cybersecurity efforts over time.

Together, these phases form a comprehensive approach to managing cybersecurity in industrial settings, promoting an adaptive and responsive security posture.
