Privileged Containers Should be Avoided

Description:

To prevent unrestricted host access, avoid privileged containers whenever possible. Privileged containers have all of the root capabilities of a host machine. They can be used as entry points for attacks and to spread malicious code or malware to compromised applications, hosts and networks.

Solution/Reference: 

From the 'Unhealthy resources' tab, select the cluster. Security Center lists the pods running privileged containers.

For these pods, set the privileged flag to 'false' on the security context of the container's spec. After making your changes, redeploy the pod with the updated spec.
