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. This is not a contract change. According to the evidence that a contract exists or that the cost of the materials is outside of the terms of a contract if one existed. Considered a time and materials contract where a change of this nature could be acceptable according to the terms of the contract. If the vendor wanted to change the terms of the contract then it would be appropriate to enter the change into the contract change control system. Answer:C is incorrect. The scope of the project will not change due to the cost of the materials. Answer:D is incorrect. There are four change control systems that should always be entertained for change: schedule, cost, scope, and contract.

is incorrect. Delphi technique is used for risk analysis, i.e., for identifying the most probable risks. Delphi is a group of experts who used to rate independently the business risk of an organization. Each expert analyzes the risk independently and then prioritizes the risk, and the result is combined into a consensus. Answer: A is incorrect. Project network diagrams help the project manager and stakeholders visualize the flow of the project work, but they are not used as a part of risk response planning. Answer: B is incorrect. Cause-and-effect analysis is used for exposing risk factors and not an effective one in risk response planning. This analysis involves the use of predictive or diagnostic analytical tool for exploring the root causes or factors that contribute to positive or negative effects or outcomes.
