Match the IPS alarm with the description.

Explanation & Hint:

1. True Positive: This is when malicious traffic is correctly identified as a threat by the IPS. The system correctly detects and potentially stops an actual attack.
2. True Negative: This is when normal traffic is correctly not identified as a threat. The IPS allows legitimate traffic to pass without any alert.
3. False Positive: This is when normal traffic is incorrectly identified as a threat. The system mistakenly perceives normal activity as malicious, which can lead to unnecessary or disruptive actions.
4. False Negative: This is when malicious traffic is not correctly identified as a threat. The system fails to detect an actual attack, which allows the malicious activity to proceed unchecked.
