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.

Reference: The formula for calculating the False Positive rate is standard across various cybersecurity

frameworks and is aligned with the Certified Network Defender (CND) course objectives that cover

the evaluation of security system performance metrics. For further details, Daniel can refer to the

CND study guide and materials that discuss the interpretation and implications of the False Positive

rate in network security.
