Question

several quantitative tools like mean time between failure (mtbf), mean time to recovery (mttr), mean time to failure (mttf), and failure in time (fit) can be used to predict the likelihood of the risk. which of these tools perform similar functions?

o mttf and mttr
o mtbf and mttf
o mtbf and fit
o fit and mttr

the risk of ddos attacks, sql injection attacks, phishing, etc., is classified under which threat category?

o compliance
o operational
o technical
o strategic

Explanation:

1. For the first question: MTBF (mean time between failure) and MTTF (mean time to failure) both deal with time - related aspects of component or system failure. MTBF is used for repairable systems to measure the average time between failures, while MTTF is for non - repairable systems to measure the average time until failure. They both focus on failure time metrics.
2. For the second question: DDoS attacks, SQL injection attacks, and phishing are related to technical vulnerabilities in systems such as network infrastructure, database management, and user - interface security. They are technical threats.

Answer:

1. B. MTBF and MTTF
2. C. Technical
