A good starting point would be to store compressed copies of your audit logs, firewall logs (network or host), and intrusion detection system (IDS) logs. Cyber security log files are also critical to investigating and prosecuting incidents because they contain sensitive information.
Log retention refers to the archiving of event logs, particularly those related to security, concerning the duration for which you store these log entries. These entries typically refer to all cybersecurity, allowing companies to hold information on security-related activities.
As a general rule, storage of audit logs should include 90 days “hot” (meaning you can actively search/report on them with your tools) and 365 days “cold” (meaning log data you have backed up or archived for long-term storage).
