cyberstrikeus CIS Kubernetes Benchmark v1.12.0 - Control 4.2.14
Description
Ensure that the Kubelet enforces the use of the RuntimeDefault seccomp profile.
Rationale
By default, Kubernetes disables the seccomp profile which ships with most container runtimes. Setting this parameter will ensure workloads running on the node are protected by the runtime's seccomp profile.
Impact
Setting this will remove some rights from pods running on the node.
Audit Procedure
Review the Kubelet's start-up parameters for the value of --seccomp-default, and check the Kubelet configuration file for the seccompDefault. If neither of these values is set, then the seccomp profile is not in use.
Remediation
Set the parameter, either via the --seccomp-default command line parameter or the seccompDefault configuration file setting.
Default Value
By default the seccomp profile is not enabled.
