NEW QUESTION # 117
Which of the following is NOT listed as a potential consequence of compromising IACS according to the ISA99 Committee scope?
Answer: C
Explanation:
The ISA99 Committee (which developed ISA/IEC 62443) defines the scope and impact of IACS cybersecurity incidents in terms of negative consequences.
Step 1: Recognized consequences
The standard identifies consequences such as:
* Financial losses
* Environmental damage
* Endangerment of public or worker safety
* Loss of proprietary or sensitive information
Step 2: Purpose of defining consequences
These consequences justify why IACS cybersecurity must prioritize availability, integrity, and safety in addition to confidentiality.
Step 3: Why increased product sales is excluded
"Increased product sales" is not a negative consequence and is not mentioned anywhere in the ISA99 scope as a result of a cybersecurity compromise.
Therefore, the correct answer is Increased product sales.

NEW QUESTION # 120
What does the System under Consideration (SuC) include in the context of ISA/IEC 62443 risk assessment?
Answer: A
Explanation:
ISA/IEC 62443-3-2 introduces the concept of the System under Consideration (SuC) as the scope boundary for risk assessment.
Step 1: Purpose of the SuC
The SuC defines exactly what is being analyzed for cybersecurity risk.
Step 2: Inclusive scope
It includes a defined collection of IACS components, systems, zones, conduits, and supporting assets that contribute to the system's function.
Step 3: Why definition matters
A clearly defined SuC ensures accurate threat modeling, impact analysis, and Security Level determination.
Step 4: Why other options are incorrect
Limiting the SuC to business assets or physical devices ignores logical, networked, and functional dependencies.
Therefore, the correct answer is a defined collection of IACS and related assets.
