The document outlines the concept of audit logs, which serve as a chronological record of security-relevant activities in various industries. It explains the implementation of an audit logging plugin for Grails projects, detailing installation, configuration, and event logging mechanisms. Additionally, it provides a sample application link and contact information for further inquiries.

2. What is Audit Log?
An Audit log is a security-relevant chronological record, set of records, and/or
destination and source of records that provide documentary evidence of the
sequence of activities that have affected at any time a specific operation,
procedure, or event.
Industries using Audit Logging:
● TeleCommunications
● Information Security
● Accounting
● Clinical Research
● Nursing Research

3. Grails Audit Logging
The Audit Logging plugin adds Grails GORM Events based Audit Logging
capabilities to a Grails project and it also adds support to domain models for
hooking into the Grails GORM events system.

4. Installation
dependencies {
compile 'org.grails.plugins:audit-logging:{version}'
}
Then:
grails compile

5. Create your Domain Artifact
After installing the plugin, you must perform the following command to let the
plugin create the audit-logging domain class within your project.
● grails audit-quickstart com.audit AuditTrail

6. Auditing of domain class
Enables audit logging using the introduced domain class AuditLogEvent which
will record insert, update, and delete events. Update events will be logged in
detail with the property name and the old and new values.
● static auditable = true

7. Event Handlers
You may use the optional event handlers in your Domain classes. Example:
● onSave
● onDelete
● onChange
If you want to use Events Handlers only, then you can use:
static auditable = [handlersOnly : true]
