How should logs be handled to ensure prompt response to irregularities?

Aggregating logs within a Security Information and Event Management (SIEM) system is crucial for prompt response to irregularities because a SIEM centralizes the collection, normalization, and analysis of logs from various sources. This allows for real-time monitoring and correlation of events, making it easier to identify patterns, anomalies, or security incidents. By having a consolidated view of logs, security teams can promptly investigate and respond to potential threats.

In contrast, storing logs locally on each machine may lead to challenges in accessing, correlating, and analyzing logs during an incident, as they may be scattered across different locations. Encrypting logs enhances security by protecting sensitive information but does not directly facilitate the quick analysis and response necessary for effective incident management. Sharing logs with all users could lead to a security risk, as it exposes sensitive information to individuals who may not have the appropriate clearance or need-to-know.
