Mean time to contain definition
Mean time to contain (MTTC) is the average time it takes for an organization to deal with a security breach or incident after it’s detected. It’s an important cybersecurity metric and helps assess the efficiency of the incident response process.
How mean time to contain works
- The process starts when an automated system or an employee spots a security issue or breach.
- The response team starts working to deal with the incident. It could cut off the affected computer systems, block malicious data traffic, or fix security gaps.
- MTTC measures the time from detecting the problem to getting it under control. This time is recorded for each incident and then averaged to find the MTTC. For example, if a system faced three incidents, and they took 2 hours, 4 hours, and 6 hours to contain, the MTTC is (2+4+6)/3 = 4 hours.
Applications of mean time to contain
- Improving incident response. By tracking MTTC, organizations can understand how effective their incident response strategies are. A shorter MTTC means a more efficient response.
- Resource allocation. MTTC helps identify areas that need more resources or training, such as types of issues that take longer to contain.
- Benchmarking and compliance. Companies can compare their MTTC with others to see if they’re meeting industry standards or compliance rules.
- Risk management. By analyzing MTTC data, companies can find weak spots and prepare better for future problems.
- Performance improvement. Keeping an eye on MTTC helps improve security protocols, staff training, and response technologies.
