Control: 4.1.1 Ensure that 'Auditing' is set to 'On'
Description
It is recommended to enable auditing on SQL Servers. Enabling auditing at the server level ensures that all existing and newly created databases on the SQL server instance are audited. Auditing policy applied on the SQL database does not override auditing policy and settings applied on the particular SQL server where the database is hosted.
Auditing tracks database events and writes them to an audit log in the Azure storage account. It also helps to maintain regulatory compliance, understand database activity, and gain insight into discrepancies and anomalies that could indicate business concerns or suspected security violations.
Default setting for Auditing is set to Off.
