Which log type tracks security-related events such as antivirus detections?

The security log is specifically designed to track security-related events within a network environment. It plays a crucial role in monitoring incidents that pertain to threats and vulnerabilities, including antivirus detections, firewall rule violations, and intrusion attempts. This log type captures data that is vital for understanding security incidents, enabling administrators to quickly respond to threats and conduct forensic investigations.

In contrast, traffic logs primarily focus on the flow of network traffic and details about sessions, such as source and destination IP addresses, ports, and protocols used. While this information is essential for analyzing network performance and usage, it does not provide the detailed security context associated with antivirus detections.

Event logs are generally broader and encompass various activities and changes in the system, including application and system events. They do not specifically zero in on security-related events like antivirus detections.

System logs are concerned with the overall operation and status of the system, recording information related to system processes and errors, but they also do not provide the specificity required to track security events.

Therefore, the security log stands out as the correct answer due to its focused nature in recording and reporting security-related incidents.
