What is the aim of implementing security controls in IACS?

The aim of implementing security controls in an Industrial Automation and Control System (IACS) is fundamentally focused on reducing vulnerabilities and protecting systems from threats. This involves identifying potential security gaps within the IACS and applying appropriate measures to safeguard against unauthorized access, data breaches, and other cybersecurity risks. By establishing robust security controls, organizations can maintain the integrity, confidentiality, and availability of their systems and the data they manage.

While other aspects such as minimizing operational downtime and enhancing user engagement may be indirect benefits of implementing security, they do not capture the primary objective, which is to protect the systems themselves from the myriad of cyber threats that could exploit existing vulnerabilities. Addressing these threats directly contributes to establishing a secure operational environment and fosters a culture of security awareness and resilience within the organization.
