In the next section, I will take you through the various roles that are integral to information security.
The current status of key security risks should be tabled and discussed at board meetings. This helps the board to determine the effectiveness of the current security governance.
Another essential reason for the board of directors to be involved in security governance is liability. Most of the organization obtains specific insurance to make good on the financial liability of the organization in the event of a security incident. This type of insurance requires those bound by it to exercise due care in the discharge of their duties. Any negligence from the board in addressing the information security risk may make the insurance void.
The roles, responsibilities, and scope of a steering committee should be clearly defined.
Understanding the roles and responsibilities as covered in this section will help the security manager to implement an effective security strategy.

A. The principle of accountability.
B. The principle of proportionality.
C. The principle of integration.
D. The principle of the code of ethics.
Answer: B. The principle of proportionality.
Explanation: The principle of proportionality requires that the access should be proportionate to the criticality of the assets and access should be provided on a need-to-know basis. The principle of accountability is important for the mapping of job descriptions; however, people with access to data may not always be accountable. Options C and D are not directly relevant to mapping job descriptions.
- The data custodian is primarily responsible for which of the following?
A. Approving access to the data.
B. The classification of assets.
C. Enhancing the value of data.
D. Ensuring all security measures are in accordance with organizational policy.
Answer: D. Ensuring all security measures are in accordance with organizational policy.
Explanation: The data custodian is responsible for ensuring that appropriate security measures are implemented and are consistent with organizational policy. The other options are not the responsibility of the data custodian.

- What is the prime role of an information security manager in a data classification process?
A. To define and ratify the data classification process.
B. To map all data to different classification levels.
C. To provide data security, as per the classification.
D. To confirm that data is properly classified.
Answer: A. To define and ratify the data classification process.
Explanation: The primary role of an information security manager is to define the structure of data classification. They need to ensure that the data classification policy is consistent with the organization's risk appetite. The mapping of data as per the classification is the responsibility of the data owner. Providing security is the responsibility of the data custodian. Confirming proper classification may be the role of the information security manager or the information security auditor.
- Which of the following is the area of most concern for the information security manager?
A. That there are vacant positions in the information security department.
B. That the information security policy is approved by senior management.
C. That the steering committee only meets on a quarterly basis.
D. That security projects are reviewed and approved by the data center manager.
Answer: D. That security projects are reviewed and approved by the data center manager.
Explanation: Security projects should be approved by the steering committee consisting of senior management. The data center manager may not be in a position to ensure the alignment of security projects with the overall enterprise objectives. This will have an adverse impact on security governance. The approval of the security policy by senior management indicates good governance. Vacant positions are not a major concern. The steering committee meeting on a quarterly basis is also not an issue.

A. The CISO.
B. The COO.
C. The head of legal.
D. The data protection officer.
Answer: B. The COO.
Explanation: The chief operating officer is the head of operational activities in the organization. Operational processes are reviewed and approved by the COO. The COO has the most thorough knowledge of the business operations and objectives. The COO is most likely the sponsor for the implementation of security projects as they have a strong influence across the organization. Sponsoring means supporting the project financially or through products or services. Although the CISO should provide security advice and recommendations, the sponsor should be the COO for effective ground-level implementation.
- Who should determine the requirements for access to data?
A. The security officer.
B. The data protection officer.
C. The compliance officer.
D. The business owner.

The steering committee consists of senior-level officials and is responsible for aligning the security strategy with the business objectives.
- The information security manager observes that not enough details are documented in the recovery plan and this may prevent meeting the recovery time objective. Which of the following compensates for the lack of details in the recovery plan and ensures that the recovery time objective is met?
A. Establishing more than one operation center.
B. Delegating authority for the recovery execution.
C. Outsourcing the recovery process.
D. Taking incremental backups of the database.
Answer: B. Delegating authority for recovery execution.
Explanation: During an incident, considerable time is taken up in escalation procedures, as decisions need to be made at each management level. The delegation of authority for the recovery execution makes the recovery process faster and more effective. However, the scope of the recovery delegation must be assessed beforehand and appropriately documented. Having multiple operation centers is too expensive to implement. Outsourcing is not a feasible option. Incremental backups do facilitate faster backups; however, they generally increase the time needed to restore the data.
- The effectiveness of SoD is best ensured by which of the following?
A. Implementing strong password rules.
B. Making available a security awareness poster on the intranet.
C. Frequent information security training.
D. Reviewing access privileges when an operator's role changes.
Answer: D. Reviewing access privileges when an operator's role changes.
Explanation: In the absence of access privilege reviews, there is the risk that a single staff member can acquire excess operational capabilities. This will defeat the objective of SoD. In order to maintain the effectiveness of SoD, it is important to review access privileges more frequently and more specifically when an operator's role changes.
- What is the prime responsibility of an information security manager?
A. To manage the risk to information assets.
B. To implement the security configuration for IT assets.
C. To conduct disaster recovery testing.
D. To close identified vulnerabilities.
Answer: A. To manage the risk to information assets.

A. The Monte Carlo method.
B. Process performance and capabilities.
C. Vulnerability assessments.
D. Risk analysis.
Answer: B. Process performance and capabilities.
Explanation: Process performance and capabilities provide a detailed perspective of the maturity levels, just like the maturity model. The other options will not help to determine the level of maturity of the process. The Monte Carlo method is a risk assessment method that uses simulations.
- Information system access should be primarily authorized by which of the following?
A. The information owner.
B. The system auditor.
C. The CISO.
D. The system administrator.
Answer: A. The information owner.
Explanation: The information owner is ultimately responsible for the protection of their data. The information owner is the best person to know the criticality of the data and who should have access to the data. Therefore, information system access should be primarily authorized by the information owner.
- The information security manager observed that the incident log is stored on a production database server. Which of the following is a major concern?
A. The unavailability of log details if the server crashes.
B. The unauthorized modification of logs by the database administrator.
C. Log capturing makes the transaction process slow.
D. Critical information may not be captured in the log files.
Answer: B. The unauthorized modification of logs by the database administrator.
Explanation: The database administrator will have access to logs if they are stored in the database server. The database administrator can modify or delete the log entries. This is a major cause of concern. Backup of the logs will address the issue of server crashes. Log capturing may not always impact transaction processing. If critical information is not captured in logs, it is a design failure and has nothing to do with log entries stored in the production database. The database administrator should not have access to logs related to the database.
- Appointing a CISO indicates which of the following?
A. The organization wants to enhance the role of senior management.
B. The organization is committed to its responsibility for information security.
C. The board of directors wants to pass on their accountability.
D. The organization wants to improve its technology architecture.
Answer: B. The organization is committed to its responsibility for information security.
Explanation: Appointing a CISO indicates that the organization wants to have a clear line of responsibility for information security. Information security is one of the focus areas for the organization. Having a CISO does not impact the role of senior management. Even if the CISO is appointed, accountability lies with the board of directors. The CISO is generally not accountable for technology projects.
- The main objective of integrating security-related roles and responsibilities is which of the following?
A. To address the security gaps that exist between assurance functions.
B. To address the unavailability of manpower.
C. To address the gap in business continuity and disaster recovery.
D. To address the complications in system development processes.
Answer: A. To address the security gaps that exist between assurance functions.
Explanation: Whenever there are shared responsibilities for information security, gaps tend to exist. Integrating the roles and responsibilities is the best way to address these gaps and ensure consistent risk management. The other options are secondary factors.
- Which of the following is the best compensating control when the same employee is responsible for updating servers, maintaining the access control, and reviewing the logs?
A. To verify that only approved changes are made.
B. To conduct penetration tests.
C. To conduct risk assessments.
D. To conduct reviews of log files by the manager.
Answer: A. To verify that only approved changes are made.
Explanation: In the absence of SoD, the best compensatory control is to ensure that only approved changes are made by the employee. This verification can either be done for all cases or on a sample basis depending on the risk involved. The review of logs by the manager may not be meaningful as an employee can manipulate the logs and hide activities from the supervisor. Penetration tests and risk assessments may not be able to detect the unauthorized activities.
- What is the responsibility of the information owner when complying with the information classification scheme?
A. To implement security measures to protect their data.
B. To determine the level of classification for their data.
C. To arrange backups of their data.
D. To delegate the processes of information classification to the system administrator.
Answer: B. To determine the level of classification for their data.
Explanation: The information owner is required to determine the level of classification for their respective data. Based on its classification, the system administrator implements the required security measures and data backups. The information owner may delegate the process of classification to some other responsible employee but not to the system administrator.
- The effectiveness of the organization's security measures is the final responsibility of which of the following?
A. The security administrator.
B. The CISO.
C. Senior management.
D. The information security auditor.
Answer: C. Senior management.
Explanation: Senior management has the final responsibility for the effectiveness of the organization's security measures. Although the authority to implement, monitor, and evaluate the security measures is delegated to the security administrator, CISO, and the information security auditor, the responsibility cannot be delegated. The final responsibility rests with senior management.
- What is the best way to ensure that responsibilities are carried out?
A. Signed non-disclosure agreements.
B. Heavy penalties for non-compliance.

- Continuous improvement of the risk management process is most likely ensured by which of the following?
A. The regular review of implemented security controls.
B. Implementing an information classification policy.
C. The adoption of a maturity model.
D. Regular audits of risk management processes.
Answer: C. The adoption of a maturity model.
Explanation: A maturity model like the CMM can be used to determine the maturity level of the risk management process from Level 0 (that is, initial) to Level 5 (that is, optimized). The organization can know where it falls and can gradually move towards higher levels and thus improve its risk management process. The other options are secondary factors.
- Information security is the responsibility of which of the following?
A. All personnel.
B. IT personnel.
C. Security personnel.
D. Operational personnel.
Answer: A. All personnel.

- Who should security policies be finally approved by?
A. Operation managers.
B. The CISO.
C. Senior management.
D. The chief technical officer (CTO)
Answer: C. Senior management.
Explanation: Senior management is in the best position to understand the key business objectives and how they should be protected by way of policies and procedures. Other officials (for example, the operation manager, CISO, and CTO) may provide necessary inputs, but final approval should be provided by senior management.
- Confidentiality of information can be best ensured by which of the following?
A. Implementing an information classification policy.
B. Implementing SoD.
C. Implementing the principle of least privilege.
D. Implementing information security audits.
Answer: C. Implementing the principle of least privilege.
Explanation: The most effective method to protect the confidentiality of information assets is to follow the principle of least privilege. The principle of least privilege ensures that access is provided only on a need-to-know basis and it should be restricted for all other users. The other options are good measures; however, in the absence of the principle of least privilege, they may not be effective.
