Revise: Robust Software and VulnerabilitiesAn audit trail records who changed what and when. During software development, this provides a history of changes to the code and improves accountability: individual changes can be linked to the people responsible for them.
For an audit trail, remember who changed what and when, then explain how this helps trace a problem to the code version where it first appeared.
Distinguish code reviews from audit trails: reviews examine code for problems; audit trails record changes so problems can be traced.
