An intrusion detection system $($IDS$)$ monitors network traffic and has multiple network taps across the environment. Events occur that could be indicative of an internal$-$to$-$external exfiltration of traffic; however the activity is legitimate and the users and systems involved have already identified this activity from previous sessions. The IDS does not fire an alert. Which IDS alert type is described here?

False positive

False negative

True positive

True negative
