Which phases are included in the IACS Cybersecurity Lifecycle?

The IACS Cybersecurity Lifecycle encompasses a comprehensive approach to managing cybersecurity throughout the different stages of an Industrial Automation and Control System (IACS). The phases included in the lifecycle typically are:

• Assess: This initial phase involves evaluating the current security posture, identifying vulnerabilities, and understanding the risks associated with the IACS. It sets the foundation for informed decision-making regarding security measures and strategy.

• Develop and Implement: Once assessments are completed, this phase involves creating a cybersecurity strategy and implementing necessary security controls and measures. This includes designing secure architectures and incorporating security into the development processes of systems.

• Maintain: This ongoing phase ensures that the implemented security measures remain effective over time. It includes patch management, continuous monitoring of security postures, and periodic re-assessments to adapt to evolving threats and vulnerabilities.

This option captures the essential aspects of the IACS Cybersecurity Lifecycle, which emphasizes the importance of assessment, proactive development and implementation of security measures, and sustained maintenance to protect critical infrastructure from cyber threats. Other choices do not wholly represent the comprehensive processes necessary for managing cybersecurity within IACS.
