Measuring and analyzing cybersecurity metrics has become crucial in ensuring the efficiency of security projects. More than ever, organizations have become increasingly vulnerable to cyberattacks, data breaches, and other security incidents. Hence, identifying key performance indicators (KPIs) and metrics is essential to tracking how well an organization is maintaining its security standards and information security management requirements. In this article, we will highlight essential key cybersecurity metrics and KPIs that will ensure the improvement of data security posture.
In today’s digital world, organizations face constant threats to their sensitive data. A recent study by the Ponemon Institute in 2020 found that the global average cost of a data breach reached $3.86 million, making it a primary concern for businesses of all sizes. This has led to a top-down approach, where senior management has become increasingly concerned with achieving compliance reports and cybersecurity risk reduction goals. Hence, monitoring and measuring relevant and actionable metrics are crucial for security and risk leaders to make informed decisions and guide their future security decision-making.
To achieve this goal, organizations need to establish a data-driven approach to measuring their cybersecurity strategy. Cybersecurity metrics and KPIs are essential tools used to measure the performance of your security controls, vulnerability, and incident management. By measuring these metrics, organizations can identify where they are performing well, where there are gaps, and where there is an urgent need to improve.
Key Metrics and KPIs for Cybersecurity
Measuring cybersecurity metrics and KPIs goes beyond measuring the overall data volume, mean time to detect (MTTD), and mean time to respond (MTTR). It also involves analyzing dynamic measurements that can help measure and improve an organization’s security posture. Therefore, the most important metric to monitor an organization’s security posture is its security rating or cybersecurity rating. Here are some essential key metrics for measuring data security posture:
Security Rating – Security rating measures an organization’s overall security posture based on its performance in 10 categories, including phishing, social engineering, patching cadence, and SSL certificates.
Vulnerability Management – This metric measures an organization’s ability to identify, prioritize, and remediate cybersecurity vulnerabilities within its environment.
Incident Response Time – Mean-Time-To-Detect (MTTD) and Mean-Time-To-Contain (MTTC) measure the response time to an incident’s detection and containment.
Employee Training – Monitoring the effectiveness of security awareness training is crucial in reducing the likelihood of insider threat data, phishing attacks, and former employee credentials being used for unauthorized purposes.
Preparedness Level – Preparedness metrics measure an organization’s level of preparedness to respond to security incidents, including identified vulnerabilities, detected intrusion attempts, patch management, communication ports, superuser access, and third-party access management.
These metrics are further divided into three primary categories:
Threat Detection and Incident Response KPIs measure the performance of an organization’s security controls in detecting and responding to security incidents.
Performance KPIs measure an organization’s ability to manage its vulnerabilities and incidents.
Preparedness KPIs measure an organization’s preparedness level to prevent, detect, and respond appropriately to security incidents.
By breaking down these metrics, organizations can identify which of their assets are most vulnerable and, most importantly, how to respond when a security incident occurs. In the next section, we will explore the importance of measuring and analyzing these metrics.
Importance of Measuring and Analyzing Metrics
Measuring and analyzing cybersecurity metrics is an ongoing process that enables organizations to improve their security posture, minimize breach costs, and guide their future security decision-making. By monitoring these metrics, organizations can identify areas that require improvement and help make informed decisions about which security controls to deploy.
Regularly measuring and analyzing cybersecurity metrics and KPIs can also help organizations:
Justify cybersecurity investments to the board: Boards often demand metrics that demonstrate the effectiveness of cybersecurity investments. By collecting data-driven metrics, security leaders can provide evidence of the positive impact of cybersecurity investments and present them to the board.
Benchmark against industry peers: Industry peers can provide an essential role in helping organizations identify their strengths and weaknesses compared to the rest of the industry. Comparing cybersecurity metrics with other organizations in the same sector can help identify areas that require improvement.
Identify third-party security risks: Today’s business environment demands that organizations share sensitive data with third parties. Therefore, it is crucial to ensure that third-party providers are implementing the same security controls as your organization. Cybersecurity metrics can help organizations measure third-party risk to identify and mitigate potential vulnerabilities.
Actionable Metrics for Daily Use
It is essential to analyze and prioritize cybersecurity metrics to ensure that organizations receive measurable value from their cybersecurity programs. As a result, it is crucial to establish a daily metric review process. Below are some actionable cybersecurity metrics that organizations can use daily.
Security Incident Severity Level: This metric helps organizations understand the potential impact of a security incident on their environment.
Detected Intrusion Attempts: This metric measures the number of intrusion attempts detected in the internal network and communication ports.
Cost Per Incident: This metric measures the total cost of a security incident, including lost data, response time, and the cost of remediation.
Vulnerability Patch Response Times: This metric measures the time taken to patch vulnerabilities found during vulnerability management.
Phishing Test Metrics: This metric measures click-through rates on phishing tests to assess the effectiveness of security awareness training.
These metrics can help organizations measure the effectiveness of their cybersecurity programs and guide future security decision-making.
Conclusion
Measuring and analyzing cybersecurity metrics and KPIs are vital for ensuring the efficiency of security projects. Organizations need to track cybersecurity metrics at different levels to evaluate how well they meet their security standards and information security management requirements. By monitoring and analyzing relevant and actionable cybersecurity metrics, organizations can improve their security posture, minimize breach costs, and make informed decisions to guide their future security decision-making. Remember that cybersecurity metrics are not set in stone: they are dynamic and should evolve with your organization’s business objectives and cybersecurity goals.
