What type of security log tracks anomalies in network traffic?

The type of security log that specifically tracks anomalies in network traffic is the anomaly log. Anomaly detection focuses on identifying unusual patterns or behaviors within network traffic that may indicate potential security threats or breaches. By analyzing traffic for deviations from established baselines, anomaly detection tools can flag potentially malicious activities such as attacks, unauthorized access, or other suspicious behaviors that may not be caught by standard filters or rules.

In contrast, application control logs are designed to monitor and control the applications being used within a network but do not focus specifically on traffic abnormalities. File filter logs concentrate on tracking and managing files that enter or exit the network, which isn't directly related to assessing overall network traffic behaviors. Intrusion prevention logs help monitor and block unauthorized intrusions but rely on predefined signatures rather than detecting anomalies based on traffic patterns.

Thus, the focus on tracking deviations and irregularities in network traffic makes the anomaly log the correct choice for identifying and responding to potential security issues effectively.
