However, this opens an opportunity for an adversary to obscure actions on the database, of a function or procedure, and this is a simple way to detect them.

This allows us to begin each subsequent line with AND, making The following line is used solely to ensure that the WHERE statement begins with a clause ADD A FILTER TO SCREEN OUT UNNECESSARY AUDIT RECORDS in the WITH clause, so that this audit has the same GUID as its equivalent If deploying this on a mirror server, include AUDIT_GUID = Assess your own situation and choose the settings accordingly.

You may find it helpful to use a database audit specification instead, to This script casts a wide net, using SQL Server's server-level audit groups. ![]() In the CREATE SERVER AUDIT SPECIFICATION statement, adjust the specification be sure you understand what each condition is doing. In the ALTER SERVER AUDIT statement, which suppresses superflous audit records, select values suited to your organization's needs. In the CREATE SERVER AUDIT statement, review all the parameters and the auditing requirements in the SQL Server 2014 STIG documents.
