Using environmental metrics, which three security requirement metric values allow the confidentiality score to be customized depending on the criticality of the affected IT asset? (Choose three.)

To determine the three security requirement metric values that allow for customization of the confidentiality score based on the criticality of the affected IT asset, let’s consider the typical classification levels used in information security. These classifications are often based on the potential impact of unauthorized disclosure of information. Here are the options you’ve provided:

1. None: This indicates no requirement for confidentiality, meaning the information is public or not sensitive.
2. Secret: This is a high level of classification, used for information where unauthorized disclosure could cause serious damage.
3. Top Secret: This is the highest level of classification, reserved for information where the highest level of protection is needed, as unauthorized disclosure could cause exceptionally grave damage.
4. Low: Indicates a lower level of sensitivity. Unauthorized disclosure could cause limited damage.
5. Medium: This represents a moderate level of sensitivity. The impact of unauthorized disclosure is more significant than ‘Low’ but not as severe as ‘High’.
6. High: This is used for information that is very sensitive, where unauthorized disclosure could cause serious damage, but not to the extent of ‘Secret’ or ‘Top Secret’.

Given these definitions, the three values that would allow you to customize the confidentiality score based on the criticality of the IT asset are:

• Low
• Medium
• High

These three levels provide a gradient of confidentiality, enabling a more nuanced and tailored approach to security based on the criticality of the IT asset. “None” indicates no need for confidentiality, while “Secret” and “Top Secret” are specific, high-level classifications that don’t offer much granularity for customization in a general IT environment.
