Explanation:
An intrusion detection system (IDS) is a device or software application that monitors network and/or system activities for malicious activities or policy violations and produces reports to a Management Station. Some systems may attempt to stop an intrusion attempt but this is neither required nor expected of a monitoring system. Intrusion detection and prevention systems (IDPS) are primarily focused on identifying possible incidents, logging information about them, and reporting attempts. In addition, organizations use IDPS for other purposes, such as identifying problems with security policies, documenting existing threats, and deterring individuals from violating security policies.
As IDS detects and gives warning when the violation of security policies of the enterprise occurs, it is a detective control.
Incorrect Answers:
B: These controls make effort to reduce the impact of a threat from problems discovered by detective controls.
As IDS only detects but not reduce the impact, hence it is not a corrective control.
C: As IDS only detects the problem when it occurs and not prior of its occurrence, it is not preventive control.
D: These controls make efforts to overcome the impact of the incident on the business, hence IDS is not a recovery control.

is incorrect. Sensitivity analysis is the quantitative risk analysis technique that: Assist in determination of risk factors that have the most potential impact Examines the extent to which the uncertainty of each element affects the object under consideration when all other uncertain elements are held at their baseline values Answer:C is incorrect. Fault tree analysis (FIA) is a technique that provides a systematic description of the combination of possible occurrences in a system, which can result in an undesirable outcome. It combines hardware failures and human failures. Answer:A is incorrect. This analysis is not a method for exposing risk factors. It is used for analyzing scenarios.

Explanation:
As in this case John and his team mates have pre-planned the alternative if the vendor would late in placing the order. Therefore, it is contingent response strategy.
Contingent response strategy, also known as contingency planning, involves adopting alternatives to deal with the risks in case of their occurrence. Unlike the mitigation planning in which mitigation looks to reduce the probability of the risk and its impact, contingency planning doesn't necessarily attempt to reduce the probability of a risk event or its impacts. Contingency comes into action when the risk event actually occurs.
Incorrect Answers:
B: Risk avoidance is the method which involves creating solutions that ensure a specific risk in not realized.
C: Risk mitigation attempts to eliminate or significantly decrease the level of risk present. Here no alternatives are pre-planned.
D: Expert judgment is utilized in developing risk responses, including feedback and guidance from risk management experts and those internal to the project qualified to provide assistance in this process.
