To mitigate the risk of unauthorized access to sensitive information by entities that have been issu | ||||
| SV-213809r395853_rule | SQL4-00-010200 | CCI-000381 | LOW | SQL Server default account [sa] must have its name changed. | SQL Server's [sa] account has special privileges required to administer the database. The [sa] account is a well-known SQL Server account name and is likely to be targeted by attackers, and is thus more prone to providing unauthorized access to the databa | ||||
| SV-213810r395709_rule | SQL4-00-011300 | CCI-000171 | MEDIUM | Where SQL Server Trace is in use for auditing purposes, SQL Server must allow only the ISSM (or individuals or roles appointed by the ISSM) to select which auditable events are to be traced. | Without the capability to restrict which roles and individuals can select which events are audited, unauthorized personnel may be able to prevent or interfere with the auditing of critical events. Suppression of auditing could permit an adversary to evad | ||||

| SV-213812r395712_rule | SQL4-00-011410 | CCI-000172 | MEDIUM | Where SQL Server Audit is in use, SQL Server must generate audit records when privileges/permissions are retrieved. | The system must monitor who/what is reading privilege/permission/role information. This requirement addresses explicit requests for privilege/permission/role membership information. It does not refer to the implicit retrieval of privileges/permissions/ro | ||||
| SV-213813r395724_rule | SQL4-00-011900 | CCI-000131 | MEDIUM | SQL Server must produce Trace or Audit records containing sufficient information to establish when the events occurred. | Information system auditing capability is critical for accurate forensic analysis.

Audit processing failures include: software/hardware errors; failures in the audit capturing mechanisms; and audit storage | ||||
| SV-213820r810820_rule | SQL4-00-013600 | CCI-000162 | MEDIUM | The audit information produced by SQL Server must be protected from unauthorized read access. | If audit data were to become compromised, competent forensic analysis and discovery of the true source of potentially malicious system activity would be difficult, if not impossible, to achieve.

A manual process for account management functions adds the risk of a potential oversight or other error. Managing accounts for the same person in multi | ||||
| SV-213859r395712_rule | SQL4-00-030410 | CCI-000172 | MEDIUM | Where SQL Server Audit is in use, SQL Server must generate audit records when unsuccessful attempts to retrieve privileges/permissions occur. | Under some circumstances, it may be useful to monitor who/what is reading privilege/permission/role information. Therefore, it must be possible to configure auditing to do this. DBMSs typically make such information available through views or functions. | ||||
| SV-213860r495393_rule | SQL4-00-030600 | CCI-000140 | HIGH | Where availability is paramount, the SQL Server must continue processing (preferably overwriting existing records, oldest first), in the event of lack of space for more Audit/Trace log records; and must keep processing after any failure of an Audit/Trace. | It is critical that when SQL Server is at risk of failing to process audit logs as required, it take action to mitigate the failure.

Accordingly, only q | ||||

However, if the privileges required for execution are at | ||||
| SV-213867r401227_rule | SQL4-00-032800 | CCI-001844 | MEDIUM | SQL Server must utilize centralized management of the content captured in audit records generated by all components of the DBMS. | Without the ability to centrally manage the content captured in the audit records, identification, troubleshooting, and correlation of suspicious behavior would be difficult and could lead to a delayed or incomplete analysis of an ongoing attack.

However, space will still be required on the DBMS server for audit records in t | ||||
| SV-213870r622558_rule | SQL4-00-033500 | CCI-001858 | MEDIUM | SQL Server or software monitoring SQL Server must provide an immediate real-time alert to appropriate support staff of all audit log failures. | It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required.
