Which of the following will be MOST effective to mitigate the risk associated with the loss of company data stored on personal devices?

  1. An acceptable use policy for personal devices
  2. Required user log-on before synchronizing data
  3. Enforced authentication and data encryption
  4. Security awareness training and testing

Answer(s): C

Explanation:

The risk associated with the loss of company data stored on personal devices is that the data may be accessed, disclosed, or modified by unauthorized parties, resulting in confidentiality, integrity, or availability breaches1. The most effective way to mitigate this risk is to enforce authentication and data encryption on the personal devices that store company data. Authentication is a process that verifies the identity of the user or device that is accessing the data, and prevents unauthorized access by requiring a password, a code, a biometric factor, or a combination of these2. Data encryption is a technique that transforms the data into an unreadable format, and requires a key to decrypt and restore the data to its original format3. By enforcing authentication and data encryption on the personal devices, the organization can ensure that only authorized users or devices can access the company data, and that the data is protected from unauthorized disclosure or modification even if the device is lost or stolen4. An acceptable use policy for personal devices, required user log-on before synchronizing data, and security awareness training and testing are not the most effective ways to mitigate the risk associated with the loss of company data stored on personal devices, as they do not provide the same level of protection asauthentication and data encryption. An acceptable use policy for personal devices is a document that defines the rules and guidelines for using personal devices for work purposes, such as the types of devices, data, and applications that are allowed, the security measures that are required,and the responsibilities and liabilities of the users and the organization5. An acceptable use policy for personal devices can help to establish acommon understanding and expectation for the use of personal devices, but it does not enforce or guarantee the compliance or effectiveness of the security measures. Required user log-on before synchronizing data is a technique that requires the user to enter their credentials before they can transfer or update the data between their personal device and the company network or system6. Required user log-on before synchronizing data can help to prevent unauthorized synchronization of data, but it does not protect the data that is already stored on the personal device. Security awareness training and testing is a process that educates and evaluates the users on the security risks and best practices for using personal devices for work purposes, such as the importance of using strong passwords, updating software, avoiding phishing emails, and reporting incidents7. Security awareness training and testing can help to increase the knowledge and behavior of the users, but it does not ensure or monitor the implementation or performance of the security measures.

If preventive controls cannot be Implemented due to technology limitations, which of the following should be done FIRST to reduce risk7

  1. Evaluate alternative controls.
  2. Redefine the business process to reduce the risk.
  3. Develop a plan to upgrade technology.
  4. Define a process for monitoring risk.

Answer(s): A

Explanation:

If preventive controls cannot be implemented due to technology limitations, the first step to reduce risk is to evaluate alternative controls. Alternative controls are those that can achieve thesame or similar objectives as the original preventive controls, but using different methods or technologies. For example, if a firewall cannot be installed due to hardware compatibility issues, an alternative control could be a network segmentation or a proxy server. Evaluating alternative controls requires assessing their feasibility, effectiveness, efficiency, and cost- benefit. Redefining the business process, developing a plan to upgrade technology, and defining a process for monitoring risk are also possible actions to reduce risk, but they are not the first step, and they may not be feasible or desirable in some situations.

Which of the following would BEST assist in reconstructing the sequence of events following a security incident across multiple IT systems in the organization's network?

  1. Network monitoring infrastructure
  2. Centralized vulnerability management
  3. Incident management process
  4. Centralized log management

Answer(s): D

Explanation:

According to the CRISC Review Manual, centralized log management is the best way to assist in reconstructing the sequence of events following a security incident across multiple IT systems in the organization's network, because it enables the collection, correlation, analysis, and retention of log data from various sources. Centralized log management can provide a comprehensive and consistent view of the activities and transactions that occurred before, during, and after the incident, and can facilitate the identification of the root cause, impact, and scope of the incident. The other options are not the best ways to assist in reconstructing the sequence of events, because they do not provide the same level of detail and accuracy as centralized log management. Network monitoring infrastructure is a tool that helps to monitor the performance and availability of the network, but it does not capture the log data from the IT systems. Centralized vulnerability management is a process that helps to identify and remediate the vulnerabilities in the IT systems, but it does not record the events and transactions that occurred on the systems. Incident management process is a process that helps to respond to and resolve the incidents, but it does not provide the log data from the IT systems.

Which of the following would be MOST helpful to a risk practitioner when ensuring that mitigated risk remains within acceptable limits?

  1. Building an organizational risk profile after updating the risk register
  2. Ensuring risk owners participate in a periodic control testing process
  3. Designing a process for risk owners to periodically review identified risk
  4. Implementing a process for ongoing monitoring of control effectiveness

Answer(s): D

Explanation:

The most helpful activity for a risk practitioner when ensuring that mitigated risk remains within acceptable limits is to implement a process for ongoing monitoring of control effectiveness. This would enable the risk practitioner to track the performance of the controls, identify any deviations or gaps, and take corrective actions as needed. Ongoing monitoring of control effectiveness would also provide assurance that the risk responses are working as intended, and that the residual risk is aligned with the risk appetite and tolerance of the enterprise.

Which of the following is the MOST important consideration when performing a risk assessment of a fire suppression system within a data center?

  1. Insurance coverage
  2. Onsite replacement availability
  3. Maintenance procedures
  4. Installation manuals

Answer(s): C

Explanation:

The MOST important consideration when performing a risk assessment of a fire suppression system within a data center is the maintenance procedures, because they ensure that the fire suppression system is functioning properly and reliably, and that it can prevent or minimize the damage caused by fire incidents. The maintenance procedures should include regular testing, inspection, and servicing of the fire suppression system components, such as sprinklers, detectors, alarms, and extinguishers. The other options are not as important as the maintenance procedures, because:
Option A: Insurance coverage is a financial measure that can compensate for the loss or damage caused by fire incidents, but it does not prevent or reduce the likelihood or impact of the fire incidents. Insurance coverage is also dependent on the terms and conditions of the insurance policy, which may not cover all the scenarios or costs of the fire incidents. Option B: Onsite replacement availability is a contingency measure that can facilitate the recovery or restoration of the fire suppression system after a fire incident, but it does not prevent or reduce the likelihood or impact of the fire incidents. Onsite replacement availability is alsodependent on the availability and compatibility of the replacement parts, which may not match the original fire suppression system specifications or requirements. Option D: Installation manuals are a reference source that can provide guidance on how to install or configure the fire suppression system, but they do not ensure that the fire suppression system is functioning properly and reliably. Installation manuals are also static documents that may not reflect the current or updated fire suppression system standards or practices.

Which of the following is the BEST way to validate the results of a vulnerability assessment?

  1. Perform a penetration test.
  2. Review security logs.
  3. Conduct a threat analysis.
  4. Perform a root cause analysis.

Answer(s): A

Explanation:

According to the CRISC Review Manual (Digital Version), the best way to validate the results of a vulnerability assessment is to perform a penetration test, which is a type of security testing that simulates an attack on the IT assets and processes to exploit the identified vulnerabilities and evaluate the potential impact and severity of the attack.

Performing a penetration test helps to:
Confirm the existence and exploitability of the vulnerabilities detected by the vulnerability assessment
Measure the effectiveness and efficiency of the existing security controls and countermeasures
Identify and prioritize the risks and gaps in the security posture of the IT assets and processes Recommend and implement appropriate remediation and mitigation actions to address the vulnerabilities and risks
Enhance the security awareness and resilience of the organization References = CRISC Review Manual (Digital Version), Chapter 1: IT Risk Identification,

Section 1.5: IT Risk Identification Methods and Techniques, pp. 36-371



Which of the following BEST helps to balance the costs and benefits of managing IT risk?

  1. Prioritizing risk responses
  2. Evaluating risk based on frequency and probability
  3. Consideringrisk factors that can be quantified
  4. Managing the risk by using controls

Answer(s): A

Explanation:

Prioritizing risk responses helps to balance the costs and benefits of managing IT risk by ensuring that the most significant risks are addressed first and that the resources allocated to risk management are used efficiently and effectively. Evaluating risk based on frequency and probability is a part of risk analysis, not risk response. Considering risk factors that can be quantified is also a part of risk analysis, and it does not necessarily capture all the relevant aspects of risk. Managing the risk by using controls is a possible risk response, but it does not guarantee that the costs and benefits of risk management are balanced, as some controls may be too expensive or ineffective for the level of risk they mitigate. References = Risk and Information Systems Control Study Manual, Chapter 4: Risk Response, page 145.



Which of the following will provide the BEST measure of compliance with IT policies?

  1. Evaluate past policy review reports.
  2. Conduct regular independent reviews.
  3. Perform penetration testing.
  4. Test staff on their compliance responsibilities.

Answer(s): B

Explanation:

Conducting regular independent reviews will provide the best measure of compliance with IT policies, as this ensures that the policies are implemented and followed consistently and effectively across the organization. Independent reviews can also identify any gaps, weaknesses, or violations in the compliance process, and recommend corrective actions or improvements.Independent reviews can be performed by internal or external auditors, regulators, or consultants, depending on the scope and purpose of the review. Evaluating past policy review reports, performing penetration testing, and testing staff on their complianceresponsibilities are not the best measures of compliance with IT policies, although they may be useful or complementary methods. Evaluating past policy review reports can provide some historical and comparative data, but it may not reflect the current or accurate situation of the compliance status. Performing penetration testing can assess the security and vulnerability of the IT systems and networks, but it does not measure the compliance with all the IT policies, such as those related to governance, operations, or quality. Testing staff on their compliance responsibilities can evaluate the awareness and knowledge of the staff, but it does not measure the actual behaviour or performance of the staff in complying with the IT policies.
