| Description |
| Protecting audit data also includes identifying and protecting the tools used to view and manipulate log data. Therefore, protecting audit tools is necessary to prevent unauthorized operation on audit data. Applications providing tools to interface with audit data will leverage user permissions and roles identifying the user accessing the tools and the corresponding rights the user enjoys in order make access decisions regarding the modification of audit tools. SQL Server is an application that does provide access to audit data. Audit tools include, but are not limited to, vendor-provided and open-source audit tools needed to successfully view and manipulate audit information system activity and records. Audit tools include custom queries and report generators. If an attacker were to gain access to audit tools, they could analyze audit logs for system weaknesses or weaknesses in the auditing itself. An attacker could also manipulate logs to hide evidence of malicious activity. Satisfies: SRG-APP-000121-DB-000202, SRG-APP-000122-DB-000203, SRG-APP-000123-DB-000204 |

| Check the server documentation for a list of approved users with access to SQL Server Audits. To create, alter, or drop a server audit, principals require the ALTER ANY SERVER AUDIT or the CONTROL SERVER permission. Review the SQL Server permissions granted to principals. Look for permissions ALTER ANY SERVER AUDIT, ALTER ANY DATABASE AUDIT, CONTROL SERVER: SELECT login.name, perm.permission_name, perm.state_desc FROM sys.server_permissions perm JOIN sys.server_principals login ON perm.grantee_principal_id = login.principal_id WHERE permission_name in ('ALTER ANY DATABASE AUDIT', 'ALTER ANY SERVER AUDIT', 'CONTROL SERVER') and login.name not like '##MS_%'; If unauthorized accounts have these privileges, this is a finding. |

| Remove audit-related permissions from individuals and roles not authorized to have them. USE master; DENY [ALTER ANY SERVER AUDIT] TO [User]; GO |
