Daniel who works as a network administrator has just deployed an in his organizations network. He wants to calculate the False Positive rate for his implementation. Which of the following formulas will he use to calculate the False Positive rate?

Show Suggested Answer Hide Answer
Suggested Answer: A

The False Positive rate (FPR) is a measure used in statistics and network security to evaluate the performance of a security system. It is calculated by dividing the number of false positives (FP) by the sum of false positives (FP) and true negatives (TN). The formula is represented as:

FPR=FP+TNFP

This rate indicates how often benign activities are incorrectly flagged as malicious, which is crucial for a network administrator like Daniel to understand the reliability of the security measures implemented.

False Positive rate? More like False Positive 'FRIGHT' rate, am I right? Eh? Eh? *crickets*

B sounds more like the formula for True Negative rate. The False Positive rate has to be A.

C looks right to me. False Negative / (False Negative + True Positive) is the formula for False Positive rate.
