Jay, a network administrator, was monitoring traffic flowing through an IDS. Unexpectedly, he received an event triggered as an alarm, although there is no active attack in progress.
Identify the type of IDS alert Jay has received in the above scenario.
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 A false positive alert can be caused by various factors, such as misconfigured IDS rules, outdated signatures, network anomalies, or legitimate traffic that resembles attack patterns.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:
