| | Kubernetes Security Check | KSV014 | Root file system is not read-only | LOW |
Expand... An immutable root file system prevents applications from writing to their local disk. This can limit intrusions, as attackers will not be able to tamper with the file system or write foreign executables to disk.

| | Kubernetes Security Check | KSV017 | Privileged container | HIGH |
Expand... Privileged containers share namespaces with the host system and do not offer any security. They should be used exclusively for system containers that require high privileges.
