NEW QUESTION # 21
Using the risk matrix below, what is the risk of a medium likelihood event with high consequence?
Answer: D
Explanation:
According to the ISA/IEC 62443 Cybersecurity Fundamentals, the risk matrix is a tool used to assess the risk of a particular event. The risk matrix is divided into three categories: likelihood, consequence, and risk. The likelihood is the probability that an event will occur, the consequence is the impact that the event will have, and the risk is the combination of the two. In this case, the risk of a medium likelihood event with high consequence is a high risk, as shown by the red cell in the matrix. References:

NEW QUESTION # 22
What is the formula for calculating risk?
Answer: A
Explanation:
The formula for risk in ISA/IEC 62443 is typically expressed as:
Risk = Threat ร Vulnerability ร Consequence
This means that risk is a product of the likelihood that a threat will exploit a vulnerability and the impact (consequence) if that event occurs. This formula is consistently used in both the general information security domain and explicitly referenced in the ISA/IEC 62443-3-2 standard in the context of IACS risk assessments.
Reference: ISA/IEC 62443-3-2:2020, Section 5.2 ("Risk is typically calculated as Threat ร Vulnerability ร Consequence"); ISA/IEC 62443-2-1:2009, Section 5.2.4.
NEW QUESTION # 23
What is the purpose of ISO/IEC 15408 (Common Criteria)?
Available Choices (select all choices that are correct)
Answer: B
Explanation:
ISO/IEC 15408, also known as the Common Criteria for Information Technology Security Evaluation, is an international standard that provides a framework for evaluating the security of IT products and systems. The purpose of the standard is to define a common set of requirements for the security functions and assurance measures of IT products and systems, and to establish a common methodology for conducting security evaluations. The standard allows users to specify their security needs and expectations in a Security Target (ST), which may be based on one or more Protection Profiles (PPs) that define security requirements for a class of products or systems. Vendors can then implement or claim compliance with the ST or PPs, and have their products or systems evaluated by independent testing laboratories against the security criteria defined in the standard. The standard also defines a scale of Evaluation Assurance Levels (EALs) that indicate the degree of confidence in the security of the evaluated product or system. The standard is intended to facilitate the development, procurement, and use of secure IT products and systems, and to promote the recognition and acceptance of evaluation results across different countries and regions.
