Why this log source is critical for security visibility
Network device logs provide the foundation for security visibility by monitoring all traffic crossing network boundaries. They are essential for detecting initial access attempts, command and control communication, lateral movement, and data exfiltration.
Network device logs can generate extremely high volumes of data. Implement proper filtering, aggregation, and retention strategies to manage storage and processing requirements while maintaining security visibility.
