Trace or Audit records must be generated when unsuccessful attempts to create categorized information (e.g., classification levels/security levels) occur.
Trace or Audit records must be generated when unsuccessful attempts to create categorized information (e.g., classification levels/security levels) occur. An XCCDF Rule
Trace or Audit records must be generated when unsuccessful attempts to create categorized information (e.g., classification levels/security levels) occur.
Medium Severity
<VulnDiscussion>Changes in categorized information must be tracked. Without an audit trail, unauthorized access to protected data could go undetected.
To aid in diagnosis, it is necessary to keep track of failed attempts in addition to the successful ones.
For detailed information on categorizing information, refer to FIPS Publication 199, Standards for Security Categorization of Federal Information and Information Systems, and FIPS Publication 200, Minimum Security Requirements for Federal Information and Information Systems.
Use of SQL Server Audit is recommended. All features of SQL Server Audit are available in the Enterprise and Developer editions of SQL Server 2014. It is not available at the database level in other editions. For this or legacy reasons, the instance may be using SQL Server Trace for auditing, which remains an acceptable solution for the time being. Note, however, that Microsoft intends to remove most aspects of Trace at some point after SQL Server 2016.
Since Trace does not provide for tracking SELECT statements, it is necessary to provide that part of the tracking at the application level. Because of this, it may also be appropriate to audit INSERT actions at the application level. However, to capture all INSERTs, whether they come from the application or bypass it, the Trace must be configured to cover them.
Use of SQL Server Audit's SCHEMA_OBJECT_ACCESS_GROUP causes capture of all accesses, successful and otherwise, to all schema-scoped objects. The [Succeeded] column in the audit output indicates the success or failure of the attempted action. Be aware, however, that it may report True in some cases where one would intuitively expect False; and some other actions that one would consider failures (such as selecting from a table that does not exist) may not appear at all.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
