This option is only available if Unlimited is unchecked. Specifies the number of audit files to be created, up to 2,147,483,647. The Unlimited check box is selected by default and applies to both the Maximum rollover files and Maximum files selections. When the Unlimited check box under Maximum rollover files is selected, there is no limit imposed on the number of audit files that will be created. Specifies that, when the maximum number of audit files is reached, any action that causes additional audit events to be generated will fail with an error. Specifies that, when the maximum number of audit files is reached, the oldest audit files are overwritten by new file content. Opens the Locate Folder - server_name dialog box to specify a file path or create a folder where the audit file is written. Specifies the location of the folder where audit data is written when the Audit destination is a file. For more information, see Write SQL Server Audit Events to the Security Log. SQL Server cannot write to the Windows Security log without configuring additional settings in Windows. The available options are a binary file, the Windows Application log, or the Windows Security log. When the audit is in a failed state, the Dedicated Administrator Connection can continue to perform audited events. Select this option when maintaining a complete audit is more important than full access to the Database Engine. The audit continues to attempt to log events and will resume if the failure condition is resolved. Actions which do not cause audited events can continue. In cases where the SQL Server Audit cannot write to the audit log this option causes database actions to fail if they would otherwise cause audited events. Select this option when an audit failure could compromise the security or integrity of the system. If the logon does not have this permission, this function will fail and an error message will be raised. The login issuing this must have the SHUTDOWN permission. This is the default selection.įorces a server shut down when the server instance writing to the target cannot write data to the audit target. Select this option when continuing operation of the Database Engine is more important than maintaining a complete audit. Selecting the Continue option can allow unaudited activity which could violate your security policies. The default minimum value is 1000 (1 second). A value of 0 indicates synchronous delivery. Specifies the amount of time in milliseconds that can elapse before audit actions are forced to be processed. This is generated automatically when you create a new audit but is editable. The following options are available on the General page of the Create Audit dialog box. Right-click the Audits folder and select New Audit. In Object Explorer, expand the Security folder. Using SQL Server Management Studio To create a server audit Users with the ALTER ANY SERVER AUDIT permission can create server audit specifications and bind them to any audit.Īfter a server audit specification is created, it can be viewed by principals with the CONTROL SERVER or ALTER ANY SERVER AUDIT permissions, the sysadmin account, or principals having explicit access to the audit. To create, alter, or drop a server audit, principals require the ALTER ANY SERVER AUDIT or the CONTROL SERVER permission. If the transaction is rolled back, the statement is also rolled back. The CREATE SERVER AUDIT statement is in a transaction's scope. When a server audit specification is created, it is in a disabled state. To create a server audit and server audit specification, using:īefore You Begin Limitations and RestrictionsĪn audit must exist before creating a server audit specification for it. For more information, see SQL Server Audit (Database Engine). You can create one server audit specification per audit, because both are created at the SQL Server instance scope. The Server Audit Specification object belongs to an audit. You can have multiple audits per SQL Server instance. The audit is at the SQL Server instance level. The SQL Server Audit object collects a single instance of server- or database-level actions and groups of actions to monitor. Auditing an instance of SQL Server or a SQL Server database involves tracking and logging events that occur on the system. This topic describes how to create a server audit and server audit specification in SQL Server by using SQL Server Management Studio or Transact-SQL.
