Log archiving
Why archive logs?
Archiving logs for a specific period is a crucial aspect of the log management process, especially since logs are what security teams turn to in the wake of a security incident. Log archives play a crucial role in forensic investigations; when data breaches are discovered, security teams need to retrieve log archives to backtrack the breach and understand what happened. While archiving logs is a well-established best practice, the exact time for which log archives need to be retained is dictated by compliance mandates as well as internal policies.
Security considerations
Attackers often try to manipulate logs to cover their tracks, so it's important to ensure log archives are secure and reliable for conducting forensic investigations. A log management tool can help implement important technical measures to ensure secure log archival.
EventLog Analyzer's secure log archival process
EventLog Analyzer is a comprehensive log management tool that can securely archive logs for any time period as required. The tool runs the log analysis and archival processes in parallel: When log data is collected by EventLog Analyzer, the data is processed by the Elasticsearch engine, and is simultaneously encrypted and archived in the location specified. The log archives can easily be reloaded into the database for analysis any time.
Here are three crucial measures that EventLog Analyzer implements to ensure security of log archives:
- Archive encryption: Archived log data is secured using the AES 256 encryption mechanism.
- Archive integrity: The solution detects log archives that have been tampered with to ensure the integrity of the data.
- Time-stamping: EventLog Analyzer uses time-stamping techniques to ensure reliability of the log archives.
