CISM Exam Dumps - Certified Information Security Manager

 The priority for implementing security controls should be based on the results of BIAs, which identify the criticality and recovery requirements of business processes and the supporting information assets. BIAs help to align security controls with business needs and objectives, and to optimize the allocation of security resources. Alignment with industry benchmarks, possibility of reputational loss due to incidents, and availability of security budget are important factors, but they are not the most important consideration for determining the priority for implementing security controls. References = CISM Review Manual, 16th Edition, page 971; CISM Review Questions, Answers & Explanations Manual, 10th Edition, page 2672

The greatest benefit of information asset classification is providing a basis for imple-menting a need-to-know policy. Information asset classification is a process of catego-rizing information based on its level of sensitivity and importance, and applying appro-priate security controls based on the level of risk associated with that information1. A need-to-know policy is a principle that states that access to information should be granted only to those individuals who require it to perform their official duties or tasks2. The purpose of a need-to-know policy is to limit the exposure of sensitive information to unauthorized or unnecessary parties, and to reduce the risk of data breaches, leaks, or misuse. Information asset classification provides a basis for implementing a need-to-know policy by:

•Defining the value and protection requirements of different types of information

•Labeling the information with the appropriate classification level, such as public, internal, confidential, secret, or top secret

•Establishing the roles and responsibilities of information owners, custodians, and users

•Enforcing access controls and encryption for the information

•Documenting the security policies and procedures for the information

By providing a basis for implementing a need-to-know policy, information asset classi-fication can help organizations to protect their sensitive information, comply with rele-vant laws and regulations, and achieve their business objectives. The other options are not the greatest benefits of information asset classification. Helping to determine the recovery point objective (RPO) is not a benefit, but rather a consequence of applying security controls based on the classification level. RPO is the acceptable amount of data loss in case of a disruption3. Supporting segregation of duties is not a benefit, but rather a prerequisite for implementing a need-to-know policy. Segregation of duties is a principle that states that no single individual should have control over two or more phases of a business process or transaction that are susceptible to errors or fraud4. De-fining resource ownership is not a benefit, but rather a component of information asset classification. Resource ownership is the assignment of accountability and authority for an information asset to an individual or a group5.

The first step when developing a business case for a new intrusion detection system (IDS) solution is to define the issues to be addressed. A business case is a document that provides the rationale and justification for initiating a project or investment. It typically includes information such as the problem statement, the objectives, the alternatives, the costs and benefits, the risks and assumptions, and the expected outcomes. The first step in developing a business case is to define the issues to be addressed, which means identifying and describing the current situation, the problems or challenges faced by the organization, and the needs or opportunities for improvement. By defining the issues to be addressed, the information security manager can establish the scope and purpose of the business case, and provide a clear and compelling problem statement that explains why a new IDS solution is needed. The other options are not the first step when developing a business case for a new IDS solution, although they may be part of the subsequent steps. Performing a cost-benefit analysis is a step that involves comparing the costs and benefits of different alternatives, including the new IDS solution and the status quo. A cost-benefit analysis can help evaluate and justify the feasibility and desirability of each alternative, and support the decision-making process. Calculating the total cost of ownership (TCO) is a step that involves estimating the direct and indirect costs associated with acquiring, operating, maintaining, and disposing of an asset or a system over its entire life cycle. A TCO calculation can help determine the long-term financial implications of investing in a new IDS solution, and compare it with other alternatives. Conducting a feasibility study is a step that involves assessing the technical, operational, legal, and economic aspects of implementing a project or an investment. A feasibility study can help identify and mitigate any potential issues or risks that may affect the success of the project or investment, and provide recommendations for improvement
