MTTD (Mean Time to Detect) is a metric that measures the average time it takes to identify or detect a problem, incident, or breach after it has occurred. It focuses on how quickly a system, team, or organization can become aware of an issue, such as a security breach, system failure, or performance degradation. A lower MTTD is critical for minimizing potential damage and improving overall response time in security or operational contexts. It is often used in cybersecurity to evaluate the effectiveness of monitoring and alerting systems. Learn more: https://en.wikipedia.org/wiki/MTTD
