Ensuring time synchronization of log sources is the most important consideration when developing a log collection and correlation strategy, as it enables the accurate and consistent analysis and correlation of log data from different sources and systems. Time synchronization can help to identify the sequence and causality of events, and to detect and respond to any anomalies or incidents. Time synchronization can also facilitate the compliance and audit of the log data, and support the forensic investigation and legal action if needed.
