  • Cost: What are the financial requirements to maintain and operate the system effectively?
  • Effort: How much manual intervention and labor are required to manage the system?

8.1.4 Evaluation Criteria and Methods for Effectiveness in Cybersecurity

8.1.4.1 1. Completeness

  • Method: Review all security features to ensure they cover all required functionalities and scenarios.
  • Purpose: Ensures that the system’s security measures are exhaustive and leave no vulnerabilities unaddressed.

8.1.4.2 2. Readability

  • Method: Evaluate the clarity of security policy documentation and user instructions.
  • Purpose: Ensures that security protocols and procedures are easy to understand and follow by all users.

8.1.4.3 3. Attractiveness

  • Method: Interview users about their experience with the system’s interface.
  • Purpose: User feedback on system aesthetics and interaction experience can provide insights into the system’s design effectiveness.

8.1.4.4 4. Clarity

  • Method: Assess the simplicity and straightforwardness of the system’s security notifications and alerts.
  • Purpose: Ensures that messages related to security are concise and clear, reducing the chance of user misunderstandings and errors.

8.1.4.5 5. Functionality

  • Method: Perform functionality tests to see if the security measures operate as intended under various scenarios.
  • Purpose: Ensures that all security functions perform their tasks correctly and effectively under normal and stress conditions.

8.1.4.6 6. Accuracy

  • Method: Check the complaints log and count the complaints from staff or customers about inaccurate information received from the system over the past three months.
  • Purpose: This helps identify how accurately the system processes and outputs data as perceived by users.

8.1.4.7 7. Accessibility

  • Method: Audit the system using accessibility tools to ensure that it meets standards for users with disabilities.
  • Purpose: Ensures that the security features are accessible to all users, including those with disabilities, enhancing system usability and compliance.

8.1.4.8 8. Timeliness

  • Method: Monitor the response times of the system to security breaches or alerts.
  • Purpose: Ensures that the system reacts promptly to potential security threats, minimizing potential damage.

8.1.4.9 9. Report Formats

  • Method: Review the formats of security logs and reports to ensure they are clear and provide actionable insights.
  • Purpose: Ensures that the data presented is useful for analysis and decision-making processes.

8.1.4.10 10. Relevance

  • Method: Assess whether the security information and functions are applicable and sufficient for the intended operational context.
  • Purpose: Ensures that the security measures are appropriate and effective for the specific needs of the organization.

8.1.4.11 11. Usability

  • Method:
    • Conduct user experience surveys and usability tests.
    • Observe how easily users can navigate and utilize security features without errors.
  • Purpose: Ensures that the system’s security features enhance user interaction without introducing unnecessary complexity.

8.1.4.12 12. Communication of Message

  • Method: Evaluate the effectiveness of communication tools within the system, such as alerts and notifications.
  • Purpose: Ensures that all communications are clear, timely, and effectively inform users of security statuses or issues.
