CREATE SERVER AUDIT SPECIFICATION (Transact-SQL)
Creates a server audit specification object using the SQL Server Audit feature. For more information, see Understanding SQL Server Audit.
Users with the ALTER ANY SERVER AUDIT permission can create server audit specifications and bind them to any audit.
After 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.
The following example creates a server audit specification called HIPPA_Audit_Specification that audits failed logins, for a SQL Server Audit called HIPPA_Audit.
CREATE SERVER AUDIT SPECIFICATION HIPPA_Audit_Specification FOR SERVER AUDIT HIPPA_Audit ADD (FAILED_LOGIN_GROUP); GO
