Splunk Enterprise must be configured to protect the log data stored in the indexes from alteration.
An XCCDF Rule
Description
<VulnDiscussion>Without non-repudiation, it is impossible to positively attribute an action to an individual (or process acting on behalf of an individual). The records stored by Splunk Enterprise must be protected against alteration. A hash is one way of performing this function. The server must not allow the removal of identifiers or date/time, or it must severely restrict the ability to do so.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
