Security requirements should be defined concurrently with other requirements to ensure that security is built into the software development process from the beginning and not added as an afterthought. This will also improve the efficiency of the development process by reducing the need for rework and testing. Security requirements should be based on the business objectives, risk assessment, and security policies of the organization, not on code review, security assessment tools, or functional requirements.

Management is primarily interested in security solutions that can address risks in the most cost-effective way. To address the needs of an organization, a business case should address appropriate security solutions in line with the organizational strategy.

Data owners are responsible for assigning user entitlements and approving access to the systems for which they are responsible. Platform security, intrusion detection and antivirus controls are all within the responsibility of the information security manager.

= Establishing metrics for each milestone is the best way to communicate the program's effectiveness to stakeholders, as it provides a clear and measurable way to track the progress, performance, and outcomes of the information security governance framework. Metrics are quantifiable indicators that can be used to evaluate the achievement of specific objectives, goals, or standards. Metrics can also help to demonstrate the value, benefits, and return on investment of the information security program, as well as to identify and address the gaps, issues, or risks. Metrics for each milestone should be aligned with the organization's strategy, vision, and mission, as well as with the expectations and needs of the stakeholders. Metrics for each milestone should also be SMART (specific, measurable, achievable, relevant, and time-bound), as well as consistent, reliable, and transparent.
The other options are not as important as establishing metrics for each milestone, as they do not provide a comprehensive and holistic way to communicate the program's effectiveness to stakeholders. A control self- assessment (CSA) process is a technique to involve the staff in assessing the design, implementation, and effectiveness of the information security controls. It can help to increase the awareness, ownership, and accountability of the staff, as well as to identify and mitigate the risks. However, a CSA process alone is not enough to communicate the program's effectiveness to stakeholders, as it does not measure the overall performance or maturity of the information security program. Automated reporting to stakeholders is a method to provide timely, accurate, and consistent information to the stakeholders about the status, results, and issues of the information security program. It can help to facilitate the communication, collaboration, and decision making among the stakeholders, as well as to ensure the compliance and transparency of the information security program. However, automated reporting alone is not enough to communicate the program's effectiveness to stakeholders, as it does not evaluate the achievement or impact of the information security program. A monitoring process for the security policy is a process to ensure that the security policy is implemented, enforced, and reviewed in accordance with the organization's objectives, standards, and regulations. It can help to maintain the relevance, adequacy, and effectiveness of the security policy, as well as to incorporate the feedback, changes, and improvements. However, a monitoring process alone is not enough to communicate the program's effectiveness to stakeholders, as it does not cover the other aspects of the information security program, such as governance, risk management, incident management, or business continuity.

= The organizational tolerance to service interruption is the most important consideration when defining a recovery strategy in a business continuity plan (BCP), as it reflects the degree of risk that the organization is willing to accept in the event of a disaster. The organizational tolerance to service interruption determines the acceptable level of downtime, data loss, or disruption that the organization can tolerate, and thus guides the selection of recovery objectives, strategies, and resources. Legal and regulatory requirements are external factors that influence the recovery strategy, but are not the primary consideration. Likelihood of a disaster is a factor that affects the recovery strategy, but is not the most important one. Geographical location of the backup site is a factor that affects the recovery strategy, but is not as critical as organizational tolerance to service interruption.
