What mode involves constant and direct monitoring of logs for a specified period?

The mode that involves constant and direct monitoring of logs for a specified period is Manual Tuning. This process requires a hands-on approach where a technician actively reviews and analyzes logs to identify vulnerabilities and anomalies. In Manual Tuning, the individual is fully engaged in the review process, ensuring that they are observing the data in real-time, which allows for quick adjustments and a better understanding of the system's behavior.

By focusing on log analysis for specific periods, a technician can refine settings, determine false positives, and understand the overall security posture of the network. This mode is particularly beneficial during initial setup phases or when introducing new systems, providing valuable insights that automated processes might overlook.

Other modes like Learn Mode, Adaptive Mode, and Automatic Tuning do not emphasize direct, ongoing human oversight of logs to the same extent and typically rely more on predefined algorithms or machine learning to adjust and optimize settings without as much immediate human analysis.
