Microsoft SQL Server SQL Audit and Event Log Events

Microsoft SQL Server SQ audit events cover categories such as account management events and application management events.

SQL Audit Events

SQL Audit Events map server-level, database-level groups of events and individual events.

The Audit action items can be individual actions such as SELECT operations on a Table, or a group of actions such as SERVER_PERMISSION_CHANGE_GROUP.

SQL Audit Events track the following three categories of Events:

Server Level: These actions include server operations, such as management changes, and logon and logoff operations.
Database Level: These actions include data manipulation languages (DML) and Data Definition Language (DDL).
Audit Level: These actions include actions in the auditing process.

Event Log Events

Event Log Events help you audit server-level, database-level and individual events.

These events consist of zero or more audit action items which can be either a group of actions (DATABASE_MIRRORING_LOGIN_GROUP) or individual actions (SELECT or REVOKE).

The Event Log Events track the following three categories of events.

Server Level: These actions include server operations such as management changes, and logon and logoff operations.
Database Level: These actions include data manipulation (DML) languages and Data Definition Language (DDL).
Audit Level: These actions include actions in the auditing process.
