Design Table Log For Free

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). Store logs in an encrypted format. See our post on Encryption Policies for more information.

Generic Tables for Audit Logging The date and time of the change. The name of the table. The key of the affected row. The user data. The type of operation performed.

Using a VDR to Store Audit Logs Because of the highly sensitive data stored on them, a virtual data room (VDR) is the ideal place to store audit logs. There are many good uses for VDRs when you need to secure and limit access to digital documents, but for audit logs there are three primary benefits.

Since security audit logs are stored on the file system and not the database, they don't have a performance impact. The main consideration of the operations teams is the storage requirements. Based on the activated event types (audit classes), data volume may vary.

The audit trail pattern can be implemented in different ways, depending on your database type, structure, and needs. However, the general idea is to create a separate table or collection that stores the metadata of every data change, such as the timestamp, user, operation, source, and old and new values.

As a baseline, most organizations keep audit logs, IDS logs and firewall logs for at least two months. On the other hand, various laws and regulations require businesses to keep logs for durations varying between six months and seven years.

Audit logs are records that record events as they happened and should be immutable. These logs provide proof of actions and help in identifying misuse. The logs provide a baseline for analysis or for an audit when initiating an investigation.

Log events in an audit logging program should at minimum include: Operating System(OS) Events. start up and shut down of the system.OS Audit Records. log on attempts (successful or unsuccessful)Application Account Information. successful and failed application authentication attempts.Application operations.

To generate audit trails in shadow tables, the safest option is to create insert, update and delete triggers, that for each affected record in the original table generate a record in the audit table. The triggers should have access to all the audit information you need to record in the shadow table.
