Which statement is TRUE regarding application of patches in an IACS environment?
In an Industrial Automation and Control Systems (IACS) environment, patches should be applied based on the organization’s risk assessment. Applying patches immediately, within a specific timeframe, or not at all could lead to unnecessary risks or missed opportunities for improving security and system performance. A risk-based approach ensures that the potential benefits of applying a patch outweigh the risks, considering factors such as the criticality of the system, potential vulnerabilities, and the impact on operations.
Patching is a risk management issue. We have to consider whether or not the benefit of patching outweighs the cost and risks associated with patching. First, we must develop the business case and educate critical decision-makers on the reason and need for patching. The final decision lies with the asset owner or their delegate.
