Ensure 'Login Auditing' is set to 'failed logins'

中等級 1自動化mssql

說明

This setting will record failed authentication attempts for SQL Server logins to the SQL Server Errorlog. This is the default setting for SQL Server. Historically, this setting has been available in all versions and editions of SQL Server. Prior to the availability of SQL Server Audit, this was the only provided mechanism for capturing logins (successful or failed). Both 'failure' and 'all' are accepted. Default: By default, only failed login attempts are captured. Runs one sqlcmd query with its defaults (Windows authentication to the local default instance); set SQLCMDSERVER, SQLCMDUSER and SQLCMDPASSWORD for another instance or SQL authentication. Needs VIEW SERVER STATE / sysadmin-level read access.
