Explanation
According to the CISM Review Manual, the primary objective when establishing a new information security program is to execute the security strategy that has been defined and approved by the senior management. The security strategy provides the direction, scope, and goals for the information security program, and aligns with the business objectives and requirements. Minimizing organizational risk, optimizing resources, and facilitating operational security are possible outcomes or benefits of the information security program, but they are not the primary objective.

Explanation
= The most important message to convey to employees in building a security risk-aware culture is that the responsibility for security rests with all employees, not just the information security function or the management. A security risk-aware culture is a collective mindset of the people in the organization working every day to protect the enterprise and its information assets from internal and external threats. A security risk-aware culture requires the workforce to know the security risks and the processes for avoiding or mitigating them, and to make thoughtful decisions that align with security policies and standards. A security risk-aware culture also incorporates a broader corporate culture of day-to-day actions that encourage employees to report security incidents, share security best practices, and participate in security awareness and training programs. A security risk-aware culture helps to reduce the human factor that causes 90 percent of all cyberattacks, and to offset the impact of corrupted or lost data, decreased revenue, regulatory fines, and reputational damage. A security risk-aware culture turns people from assets that must be protected into assets that actively contribute to the cybersecurity and risk management posture and elevate security to being a business enabler rather than a business impediment123.
Personal information requires different security controls than sensitive information is a true statement, but it is not the most important message to convey to employees in building a security risk-aware culture. Personal information is any information that can identify or relate to a natural person, such as name, address, email, phone number, social security number, etc. Sensitive information is any information that is confidential, proprietary, or has a high value or impact to the organization, such as trade secrets, financial data, customer data, intellectual property, etc. Different types of information may have different legal, regulatory, contractual, or ethical obligations to protect them from unauthorized access, use, disclosure, modification, or destruction.
Therefore, different security controls may be applied to personal and sensitive information based on their classification, such as encryption, access control, retention, disposal, etc. However, this message does not address the broader concept of security risk-aware culture, which is not limited to information classification and protection, but also encompasses the behaviors, attitudes, and values of the employees towards security.
Employee access should be based on the principle of least privilege is a good practice, but it is not the most important message to convey to employees in building a security risk-aware culture. The principle of least privilege states that users should only have the minimum level of access and permissions that are necessary to perform their job functions, and no more. This principle helps to reduce the risk of unauthorized or inappropriate actions, such as data leakage, fraud, sabotage, etc., by limiting the exposure and impact of user activities. However, this message does not capture the essence of security risk-aware culture, which is not only about access control, but also about the awareness, understanding, and commitment of the employees to security.
Understanding an information asset's value is critical to risk management is a valid point, but it is not the most important message to convey to employees in building a security risk-aware culture. Understanding an information asset's value is essential to determine the potential impact and likelihood of a security risk, and to prioritize the appropriate risk response strategies, such as avoidance, mitigation, transfer, or acceptance.
However, this message does not reflect the holistic nature of security risk-aware culture, which is not only about risk assessment, but also about risk communication, risk treatment, and risk monitoring.

Explanation
Installing an intrusion detection system (IDS) will allow the information security manager to better pinpoint the source of the attack so that countermeasures may then be taken. An IDS is not limited to detection of attacks originating externally. Proper placement of agents on the internal network can be effectively used to detect an internally based attack. Requiring the use of strong passwords will not be sufficiently effective against a network-based attack. Assigning IP addresses would not be effective since these can be spoofed.
Implementing centralized logging software will not necessarily provide information on the source of the attack.

Explanation
The effect of the theft of customer data or web site defacement by hackers could lead to a permanent decline in customer confidence, which does not lend itself to measurement by quantitative techniques. Loss of a majority of the software development team could have similar unpredictable repercussions. However, the loss of electrical power for a short duration is more easily measurable and can be quantified into monetary amounts that can be assessed with quantitative techniques.
