Description
If audit data were to become compromised then competent forensic analysis and discovery of the true source of potentially malicious system activity is impossible to achieve. To ensure the veracity of audit data the information system and/or SharePoint must protect audit information from unauthorized deletion. SharePoint is an integrated product with comprehensive built-in auditing capabilities that works with the Windows system event log. Additional trace logs and usage logs are created by the application and are placed in a designated folder. Logs of actions taken by users of site content (editing, modifying, viewing, deleting, etc.) are stored in a SQL database.
