A false positive alert is a type of IDS alert that occurs when the IDS mistakenly identifies benign or

normal traffic as malicious or suspicious, and triggers an alarm, although there is no active attack in

progress. A false positive alert can be caused by various factors, such as misconfigured IDS rules,

outdated signatures, network anomalies, or legitimate traffic that resembles attack patterns. A false

positive alert can waste the time and resources of the security team, as they have to investigate and

verify the alert, and also reduce the trust and confidence in the IDS. A false positive alert can be

reduced by tuning and updating the IDS, filtering out irrelevant traffic, and using multiple detection

methods. A false positive alert is the type of IDS alert Jay has received in the above scenario, as he

received an event triggered as an alarm, although there is no active attack in progress. Reference:
