MTTD and MTTR: Two Metrics to Improve Your Cybersecurity
For any organization to protect itself from cyberattacks and data breaches, it’s critical to discover and respond to cyber threats as quickly as possible. Shutting the window of vulnerabilities promptly makes the difference between a mild compromise and a catastrophic data breach. Understanding your ability to do so gives your organization a powerful way to determine holes in your defenses and areas where your team needs to improve.
MTTD and MTTR Explained
While there are dozens of metrics available to determine success, here are two key cybersecurity performance indicators every organization should monitor.
- Mean Time to Detect (MTTD): Your MTTD is the average time it takes to discover a security threat or incident.
- Mean Time to Respond (MTTR): Your MTTR measures the average time it takes to control and remediate a threat.
Your MTTD and MTTR depend on a number of factors, including the size and complexity of your network, the size and expertise of your IT staff, your industry, and more. And different companies measure things in different ways. There are no industry-standard approaches to measuring MTTD and MTTR, so granular comparisons between organizations can be problematic apples-vs-oranges affairs.
