MTTD
MTTD (Mean Time To Detect) is a key measurement in cybersecurity that shows how quickly a company can spot security problems or threats. Think of it like measuring how long it takes a security guard to notice something suspicious. A lower MTTD means the company is better at quickly finding potential security issues, which is crucial because faster detection usually means less damage from cyber attacks. This term often appears alongside its partner metric MTTR (Mean Time To Respond). Together, these measurements help show how effective a security team is at protecting an organization.

Example Interview Questions
Senior Level Questions
Q: How would you develop a strategy to reduce MTTD across an organization?
Expected Answer: A strong answer should discuss implementing automated detection tools, establishing clear metrics and baselines, training security teams, and creating efficient incident response processes. They should also mention the importance of regular testing and continuous improvement.
Q: How do you balance MTTD improvement with false positive rates?
Expected Answer: The candidate should explain the trade-off between quick detection and accuracy, discussing methods to tune detection systems, prioritize alerts, and use threat intelligence to reduce false positives while maintaining effective detection times.
Mid Level Questions
Q: What tools and techniques have you used to measure and improve MTTD?
Expected Answer: Should be able to discuss specific security monitoring tools, explain how they track detection times, and describe methods they've used to improve detection speeds while maintaining accuracy.
Q: How do you prioritize different types of security alerts to maintain optimal MTTD?
Expected Answer: Should explain their approach to alert classification, discuss how they determine alert severity, and describe their process for handling different types of security incidents.
Junior Level Questions
Q: What is MTTD and why is it important?
Expected Answer: Should be able to explain that MTTD measures how quickly threats are detected and why faster detection is crucial for minimizing damage from security incidents.
Q: What factors can affect MTTD?
Expected Answer: Should mention factors like monitoring tool effectiveness, alert volume, staff training, and process efficiency that can impact how quickly threats are detected.
