Information, Computer and Network Security Terms Glossary and
In accounting, an audit trail is the sequence of paperwork that validates or invalidates accounting entries. In computing, the term is also used for an electronic or paper log used to track computer activity. For example, an employee might have access to a section of a network in a corporation such as billing but be unauthorized to access all other sections. An audit trail will show where in the network the employee has accessed to and what has been done.
