The Create Hardlink Over Sensitive Files event in a Kubernetes cluster indicates that a process attempted to create a hardlink to a sensitive file.
This event could potentially be a security concern as it may indicate an unauthorized attempt to modify or access sensitive data.
It is important to investigate the source of this event and take appropriate actions to ensure the integrity and confidentiality of the sensitive files in the cluster.
To investigate further, you can:
Use kubectl to check the logs of the relevant pod or container to identify the process that triggered the event.
Inspect the file system permissions and ownership of the sensitive files to ensure they are properly secured.
Consider implementing file integrity monitoring tools or auditing mechanisms to detect and prevent unauthorized modifications to sensitive files.
