Which of the following is NOT a common cybersecurity metric?

  1. Mean Time to Detect (MTTD)

  2. Mean Time to Respond (MTTR)

  3. Return on Security Investment (ROSI)

  4. Mean Time Between Failures (MTBF)

Show answer
Correct Option: D
Explanation:

MTBF is a reliability metric used in engineering to measure the average time between failures of a system. It is not a specific cybersecurity metric.

What is the purpose of Mean Time to Detect (MTTD)?

  1. To measure the average time it takes to detect a security incident

  2. To measure the average time it takes to respond to a security incident

  3. To measure the average time it takes to resolve a security incident

  4. To measure the average time it takes to recover from a security incident

Show answer
Correct Option: A
Explanation:

MTTD measures the time it takes from the occurrence of a security incident to its detection by security personnel.

Which of the following is NOT a common cybersecurity measurement framework?

  1. NIST Cybersecurity Framework

  2. ISO 27001/27002

  3. COBIT

  4. PCI DSS

Show answer
Correct Option: D
Explanation:

PCI DSS is a security standard specifically designed for the payment card industry, while the other options are more general cybersecurity frameworks.

What is the purpose of Return on Security Investment (ROSI)?

  1. To measure the financial benefits of cybersecurity investments

  2. To measure the effectiveness of cybersecurity controls

  3. To measure the compliance of an organization with cybersecurity regulations

  4. To measure the risk exposure of an organization

Show answer
Correct Option: A
Explanation:

ROSI aims to quantify the financial value gained from cybersecurity investments, such as reduced costs due to security breaches or improved productivity.

Which of the following is NOT a common cybersecurity metric for measuring the effectiveness of security controls?

  1. False Positive Rate (FPR)

  2. True Positive Rate (TPR)

  3. Mean Time to Resolution (MTTR)

  4. Detection Rate

Show answer
Correct Option: C
Explanation:

MTTR is a metric used to measure the time it takes to resolve a security incident, while the other options are metrics for evaluating the performance of security controls.

What is the purpose of Mean Time to Respond (MTTR)?

  1. To measure the average time it takes to detect a security incident

  2. To measure the average time it takes to respond to a security incident

  3. To measure the average time it takes to resolve a security incident

  4. To measure the average time it takes to recover from a security incident

Show answer
Correct Option: B
Explanation:

MTTR measures the time it takes from the detection of a security incident to the initiation of a response.

Which of the following is NOT a common cybersecurity metric for measuring risk exposure?

  1. Annualized Loss Expectancy (ALE)

  2. Single Loss Expectancy (SLE)

  3. Value at Risk (VaR)

  4. Mean Time to Failure (MTTF)

Show answer
Correct Option: D
Explanation:

MTTF is a reliability metric used in engineering to measure the average time between failures of a system. It is not a specific cybersecurity metric for measuring risk exposure.

What is the purpose of Detection Rate?

  1. To measure the proportion of security incidents that are successfully detected

  2. To measure the proportion of security incidents that are successfully responded to

  3. To measure the proportion of security incidents that are successfully resolved

  4. To measure the proportion of security incidents that are successfully recovered from

Show answer
Correct Option: A
Explanation:

Detection Rate measures the effectiveness of security controls in identifying security incidents.

Which of the following is NOT a common cybersecurity metric for measuring compliance?

  1. Compliance Score

  2. Compliance Gap Analysis

  3. Security Posture Assessment

  4. Risk Assessment

Show answer
Correct Option: D
Explanation:

Risk Assessment is a process of identifying, evaluating, and prioritizing risks, while the other options are metrics for measuring compliance with cybersecurity regulations or standards.

What is the purpose of Security Posture Assessment?

  1. To measure the effectiveness of security controls

  2. To measure the compliance of an organization with cybersecurity regulations

  3. To measure the risk exposure of an organization

  4. To measure the financial benefits of cybersecurity investments

Show answer
Correct Option: A
Explanation:

Security Posture Assessment evaluates the effectiveness of an organization's security controls in protecting against cyber threats.

Which of the following is NOT a common cybersecurity metric for measuring the financial impact of security incidents?

  1. Cost of a Data Breach

  2. Return on Security Investment (ROSI)

  3. Value at Risk (VaR)

  4. Annualized Loss Expectancy (ALE)

Show answer
Correct Option: B
Explanation:

ROSI is a metric for measuring the financial benefits of cybersecurity investments, while the other options are metrics for measuring the financial impact of security incidents.

What is the purpose of Compliance Score?

  1. To measure the effectiveness of security controls

  2. To measure the compliance of an organization with cybersecurity regulations

  3. To measure the risk exposure of an organization

  4. To measure the financial benefits of cybersecurity investments

Show answer
Correct Option: B
Explanation:

Compliance Score measures an organization's adherence to cybersecurity regulations or standards.

Which of the following is NOT a common cybersecurity metric for measuring the effectiveness of security awareness training?

  1. Security Awareness Score

  2. Phishing Simulation Results

  3. Security Incident Reports

  4. Employee Surveys

Show answer
Correct Option: C
Explanation:

Security Incident Reports are used to track and analyze security incidents, while the other options are metrics for measuring the effectiveness of security awareness training.

What is the purpose of Phishing Simulation Results?

  1. To measure the effectiveness of security controls

  2. To measure the compliance of an organization with cybersecurity regulations

  3. To measure the risk exposure of an organization

  4. To measure the effectiveness of security awareness training

Show answer
Correct Option: D
Explanation:

Phishing Simulation Results evaluate the ability of employees to identify and avoid phishing attacks.

Which of the following is NOT a common cybersecurity metric for measuring the effectiveness of incident response plans?

  1. Incident Response Time

  2. Incident Containment Time

  3. Incident Resolution Time

  4. Mean Time to Detect (MTTD)

Show answer
Correct Option: D
Explanation:

MTTD is a metric for measuring the time it takes to detect a security incident, while the other options are metrics for measuring the effectiveness of incident response plans.
