What type of information can log files provide in a forensic investigation?

Log files are invaluable in forensic investigations because they provide a detailed timeline of events and user actions. Each entry in a log file typically includes timestamps, user IDs, actions performed, and system responses, which allows investigators to piece together a chronological sequence of activities related to a specific incident. This timeline can help establish when an event occurred, what actions were taken, and potentially who was responsible, making it crucial for understanding the context of the incident and tracing malicious activities.

The other choices, while they may serve other purposes, do not directly contribute to the forensic understanding of events as log files do. Visual representations of data are useful for data analysis but do not provide the granular level of detail about actions and events. Legal documentation plays a significant role in the legal processes that may follow a forensic investigation, but it does not document events in a real-time or detailed manner in the same way log files do. Complaints and feedback from users can give insight into user experiences and operational issues but are not reliable sources for reconstructing specific timelines or actions taken within systems.
