The purposes of audit records on an information system are:
A. Troubleshooting: Audit records help to identify the causes of errors or system failures, and can be used to troubleshoot problems that occur within an information system. By reviewing audit records, system administrators can determine what happened before and after an event, identify the source of the problem, and take corrective action to prevent future occurrences.
B. Investigation: Audit records provide a valuable source of information for investigating security incidents or suspicious activities. They can be used to track user activity, detect unauthorized access attempts, and identify changes made to system configurations. Audit records can also be used to provide evidence in legal proceedings, or to assist in forensic analysis of security breaches or other incidents.
C. Upgradation: Audit records may also be used for system upgrades, particularly in the context of compliance with industry standards or regulatory requirements. For example, audit records can be used to demonstrate that a system has been updated to address known vulnerabilities or to meet new security standards.
D. Backup: While audit records themselves are not typically used as a backup mechanism, they can be included in system backups to ensure that they are preserved in the event of a system failure or disaster. This can be particularly important for compliance purposes, as audit records may be required to be retained for a certain period of time.
In summary, the primary purposes of audit records on an information system are troubleshooting and investigation, with potential secondary benefits in the areas of system upgrades and backup.
