OpenShift must protect system journal file from any type of unauthorized access by setting owner permissions.
An XCCDF Rule
Description
<VulnDiscussion>OpenShift follows the principle of least privilege, which aims to restrict access to resources based on user roles and responsibilities. This separation of privileges helps mitigate the risk of unauthorized modifications or unauthorized access by users or processes that do not need to interact with the file. Protecting the system journal file from unauthorized access helps safeguard against potential security threats. The system journal file contains critical log data that is vital for system analysis, troubleshooting, and security auditing. Unauthorized users gaining access to the file may exploit vulnerabilities, tamper with logs, or extract sensitive information. By setting strict file owner permissions, OpenShift minimizes the risk of unauthorized individuals or processes accessing or modifying the journal file, reducing the likelihood of security breaches.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
