For log files to be admissible in court, how often must they be kept?

• A. Weekly
• B. Monthly
• C. Continuously
• D. All log files are admissible in court no matter their frequency

Answer: (C)

Keeping logs in an unbroken, continuous stream is essential for admissibility. When logs are captured continuously, you have a complete timeline of events with time-stamped records that support reconstruction of what happened and when, which is crucial for authenticity and non-repudiation in court. Continuous collection also makes it easier to preserve data integrity through mechanisms like cryptographic hashes, secure storage, and a clear chain of custody, reducing the risk that gaps or tampering could be challenged. If logging is only done weekly or monthly, gaps can appear that obscure the exact sequence of events and provide opportunities to dispute what occurred. The notion that all log files are admissible regardless of frequency isn’t accurate, because incomplete or inconsistent logs can be questioned or excluded; continuous logging strengthens reliability and the ability to defend the evidence’s integrity.
