Question 1 of 30

In a corporate environment, a network security analyst is tasked with evaluating the effectiveness of the Sourcefire IPS in detecting and mitigating potential threats. The analyst observes that the IPS has logged multiple alerts related to SQL injection attempts over the past week. To assess the IPS\'s performance, the analyst decides to calculate the true positive rate (TPR) of the IPS based on the following data: out of 100 total SQL injection attempts, 80 were correctly identified as threats by the IPS, while 20 were false negatives (missed detections). What is the true positive rate of the IPS in this scenario?

0.8 (or 80%)

0.6 (or 60%)

0.75 (or 75%)

0.9 (or 90%)
