Why is logging and monitoring critical in network security?

Logging and monitoring are essential components of network security because they provide the ability to detect, investigate, and respond to security incidents effectively. By systematically collecting data about network activity, any anomalies or suspicious behavior can be identified promptly. This proactive approach allows security teams to analyze incidents, determine their origins, and mitigate potential threats before they escalate.

Furthermore, logging offers a historical record of events that can be invaluable during investigations, helping to establish timelines and understand the nature of an attack. Without logging and monitoring, organizations would lack visibility into their network's operations, leaving them vulnerable to undetected intrusions and attacks. This capability not only enhances security posture but also aids in compliance with various regulatory requirements that mandate monitoring and logging practices.
