What is the outcome of a successful incident investigation in an IACS environment?

The outcome of a successful incident investigation in an IACS (Industrial Automation and Control Systems) environment lies in the ability to gain a clearer understanding of the causes of incidents and to implement effective preventive measures. This involves a thorough analysis of what went wrong, why it occurred, and how similar incidents can be avoided in the future.

By conducting a detailed investigation, organizations can identify vulnerabilities and weaknesses in their systems and processes. This understanding enables them to develop targeted strategies to mitigate risks, enhance system performance, and bolster overall security. The focus on prevention also contributes to the long-term reliability and resilience of systems, ultimately reducing the likelihood of future incidents.

The other options present scenarios that are generally adverse outcomes. An increase in hardware failures or higher operational costs due to redundancy would indicate a lack of effective investigation. Moreover, increased user complaints about system functionality suggests issues have not been adequately addressed. In contrast, the successful investigation outcomes lead to improvement rather than deterioration in system performance and reliability.
