Anaudit trail (also calledaudit 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, event, or device.[1][2] Audit records typically result from activities such asfinancial transactions,[3]scientific research and health care data transactions,[4] orcommunications by individual people, systems, accounts, or other entities.
The process that creates an audit trail is typically required to always run in aprivileged mode, so it can access and supervise all actions from all users; a normal user should not be allowed to stop/change it. Furthermore, for the same reason, the trail file ordatabase table with a trail should not be accessible to normal users. Another way of handling this issue is through the use of a role-based security model in the software.[5] The software can operate with the closed-looped controls, or as a 'closed system', as required by many companies when using audit trail functionality.
Intelecommunications, the term means a record of both completed and attempted accesses and service, ordata forming a logical path linking asequence of events, used to trace the transactions that have affected the contents of a record.
Ininformation orcommunications security,information audit means a chronological record ofsystem activities to enable the reconstruction and examination of the sequence of events and/or changes in an event. Information put away or transmitted in paired structure that might be depended upon incourt. An audit trail is a progression of records of computer data about a working framework, an application, or client exercises. Computer frameworks may have a few audit trails each gave to a specific sort of action[6][circular reference]. Related to proper apparatuses and systems, audit trails can help with distinguishing security infringement, execution issues and application issues. Routine log audits and investigation are valuable for distinguishing security episodes, approach infringement, fake movement, and operational issues soon after they have happened, and for giving information valuable to settling such issues.[7] Audit logs can likewise be valuable for performingforensic investigation, supporting the associations inside examinations, setting upbaselines, and distinguishing operational patterns and long run issues.
Innursing research, it refers to the act of maintaining a running log orjournal of decisions relating to a research project, thus making clear the steps taken and changes made to the originalprotocol.
Inaccounting, it refers todocumentation of detailed transactions supporting summaryledger entries. This documentation may be on paper or on electronic records.
In finance, it refers to an order (any firm indication of a willingness to buy or sell a security) tracking system, or consolidated audit trail, with respect to the trading of securities, that would capture order event information for orders in securities from the time of the receipt of an order, and further documenting the life of the order through the process of routing, modification, cancellation, and execution (in whole or in part) of the order.[8][9]
Inonline proofing, it pertains to theversion history of a piece of artwork, design, photograph, video, or web design proof in a project.
Inclinical research, server based systems such asclinical trial management systems (CTMS) require audit trails. Anything regulatory orQA/QC related also requires audit trails.
Inpharmaceutical manufacturing, it is aGood Manufacturing Practice regulatory requirement software generate audit trails, but not all software have audit trail functionality built-in. The first 'generic' audit trail generating software came out late 2021.[citation needed] The software is called Audit Trail Control, capable of fulfilling regulatory requirements for any software used in pharmaceutical manufacturing.[citation needed]
