Explanation:
Vulnerabilities represent characteristics of information resources that may be exploited by a threat. The given scenario describes such a situation, hence it is a vulnerability.
Incorrect Answers:
A: Probabilities represent the likelihood of the occurrence of a threat, and this scenario does not describe a probability.
B: Threats are circumstances or events with the potential to cause harm to information resources. This scenario does not describe a threat.
D: Impacts represent the outcome or result of a threat exploiting a vulnerability. The stem does not describe an impact.

Explanation:
NIST SP 800-53 is used to review security in any organization, that is, in reviewing physical security. The Physical and Environmental Protection family includes 19 different controls. Organizations use these controls for better physical security. These controls are reviewed to determine if they are relevant to a particular organization or not. Many of the controls described include additional references that provide more details on how to implement them. The National Institute of Standards and Technology (NIST) SP
800-53 rev 3 identifies 18 families of controls. It groups these controls into three classes:
Technical

Operational

Management

Explanation:
Risk probability and assessment is completed through interviews and meetings with the participants that are most familiar with the risk events, the project work, or have other information that can help determine the affect of the risk.
Incorrect Answers:
B: The true cost of the risk event is not a qualitative risk assessment approach. It is often done during the quantitative risk analysis process.
C: The probability and impact matrix is a tool and technique to prioritize the risk events, but it's not the best answer for assessing risk events within the project.
D: Root cause analysis is a risk identification technique, not a qualitative assessment tool.
