A security manager is tasked with calculating the reliability of the organization's network infrastructure. Over the course of a single year, the total operational period was 8760 hours, during which the system encountered 5 unplanned outages. What is the Mean Time Between Failures (MTBF) for this network infrastructure based on the provided data?
Mean Time Between Failures (MTBF) is a reliability metric that indicates the average time between system breakdowns or failures. It is calculated by dividing the total operational time by the number of failures.
MTBF Calculation:
Total operational time (T) = 8760 hours (given)
Number of unplanned outages (N) = 5 (given)
MTBF = T / N
MTBF = 8760 hours / 5 outages = 1752 hours
