Description

For completeness of forensic analysis, it is necessary to know how long a user's (or other principal's) connection to SQL Server lasts. This can be achieved by recording disconnections, in addition to logons/connections, in the audit logs. Disconnection may be initiated by the user or forced by the system (as in a timeout) or result from a system or network failure. To the greatest extent possible, all disconnections must be logged.

Determine if an audit is configured and started by executing the following query: SELECT name AS 'Audit Name', status_desc AS 'Audit Status', audit_file_path AS 'Current Audit File' FROM sys.dm_server_audit_status If no records are returned, this is a finding. Execute the following query to verify the following events are included in the server audit specification: APPLICATION_ROLE_CHANGE_PASSWORD_GROUP AUDIT_CHANGE_GROUP BACKUP_RESTORE_GROUP DATABASE_CHANGE_GROUP DATABASE_OBJECT_CHANGE_GROUP DATABASE_OBJECT_OWNERSHIP_CHANGE_GROUP DATABASE_OBJECT_PERMISSION_CHANGE_GROUP DATABASE_OPERATION_GROUP DATABASE_OWNERSHIP_CHANGE_GROUP DATABASE_PERMISSION_CHANGE_GROUP DATABASE_PRINCIPAL_CHANGE_GROUP DATABASE_PRINCIPAL_IMPERSONATION_GROUP DATABASE_ROLE_MEMBER_CHANGE_GROUP DBCC_GROUP LOGIN_CHANGE_PASSWORD_GROUP LOGOUT_GROUP SCHEMA_OBJECT_CHANGE_GROUP SCHEMA_OBJECT_OWNERSHIP_CHANGE_GROUP SCHEMA_OBJECT_PERMISSION_CHANGE_GROUP SERVER_OBJECT_CHANGE_GROUP SERVER_OBJECT_OWNERSHIP_CHANGE_GROUP SERVER_OBJECT_PERMISSION_CHANGE_GROUP SERVER_OPERATION_GROUP SERVER_PERMISSION_CHANGE_GROUP SERVER_PRINCIPAL_CHANGE_GROUP SERVER_PRINCIPAL_IMPERSONATION_GROUP SERVER_ROLE_MEMBER_CHANGE_GROUP SERVER_STATE_CHANGE_GROUP TRACE_CHANGE_GROUP USER_CHANGE_PASSWORD_GROUP SELECT a.name AS 'AuditName', s.name AS 'SpecName', d.audit_action_name AS 'ActionName', d.audited_result AS 'Result' FROM sys.server_audit_specifications s JOIN sys.server_audits a ON s.audit_guid = a.audit_guid JOIN sys.server_audit_specification_details d ON s.server_specification_id = d.server_specification_id WHERE a.is_state_enabled = 1 AND d.audit_action_name IN ('APPLICATION_ROLE_CHANGE_PASSWORD_GROUP', 'AUDIT_CHANGE_GROUP', 'BACKUP_RESTORE_GROUP', 'DATABASE_CHANGE_GROUP', 'DATABASE_OBJECT_CHANGE_GROUP', 'DATABASE_OBJECT_OWNERSHIP_CHANGE_GROUP', 'DATABASE_OBJECT_PERMISSION_CHANGE_GROUP', 'DATABASE_OPERATION_GROUP', 'DATABASE_OWNERSHIP_CHANGE_GROUP', 'DATABASE_PERMISSION_CHANGE_GROUP', 'DATABASE_PRINCIPAL_CHANGE_GROUP', 'DATABASE_PRINCIPAL_IMPERSONATION_GROUP', 'DATABASE_ROLE_MEMBER_CHANGE_GROUP', 'DBCC_GROUP', 'LOGIN_CHANGE_PASSWORD_GROUP', 'LOGOUT_GROUP', 'SCHEMA_OBJECT_CHANGE_GROUP', 'SCHEMA_OBJECT_OWNERSHIP_CHANGE_GROUP', 'SCHEMA_OBJECT_PERMISSION_CHANGE_GROUP', 'SERVER_OBJECT_CHANGE_GROUP', 'SERVER_OBJECT_OWNERSHIP_CHANGE_GROUP', 'SERVER_OBJECT_PERMISSION_CHANGE_GROUP', 'SERVER_OPERATION_GROUP', 'SERVER_PERMISSION_CHANGE_GROUP', 'SERVER_PRINCIPAL_CHANGE_GROUP', 'SERVER_PRINCIPAL_IMPERSONATION_GROUP', 'SERVER_ROLE_MEMBER_CHANGE_GROUP', 'SERVER_STATE_CHANGE_GROUP', 'TRACE_CHANGE_GROUP', 'USER_CHANGE_PASSWORD_GROUP' ) Order by d.audit_action_name If the identified groups are not returned, this is a finding.
