Mitigation checklist
- To mitigate the risk of IPsec pre-shared key (PSK) disclosure, implement strict Kubernetes Role-Based Access Control (RBAC) policies to limit access to Submariner Custom Resources. Ensure that only authorized administrators and systems are granted permissions to view `submariner` Custom Resources within their namespaces. Additionally, exercise caution when collecting and storing diagnostic data, such as must-gather bundles, and when managing GitOps repositories, as these may inadvertently expose the cleartext PSK.
