The process of storing logged data for compliance and conducting forensic analysis is known as log retention. This practice involves keeping records of the activities and transactions occurring within a network or system over a defined period. Log retention ensures that organizations have the necessary data available for auditing purposes and can investigate any incidents or anomalies that may arise.

By adhering to log retention policies, organizations can meet regulatory compliance requirements and maintain an audit trail of user activities, system changes, and security events. This stored data is crucial for forensic analysis, allowing security teams to trace back through events to identify the origin of a security breach or other issues.

Data encryption focuses on protecting data confidentiality and is not specifically about logging or retention. Audit trails refer to a record of actions taken by users but do not encompass the ongoing storage and management of logs for future reference. Traffic analysis deals with examining network traffic patterns and behavior, which is a different aspect of network security monitoring.
