OpenShift - Security Context Constraints
In addition to the RBAC resources that control what a user can do, OpenShift Container Platform provides security context constraints (SCC) that control the actions that a pod can perform and what it has the ability to access.
SCC is a policy object that has special rules that correspond with the infrastructure itself, unlike RBAC that has rules that correspond with the Platform. It helps us define what Linux access-control features the container should be able to request/run. Example: Linux Capabilities, SECCOMP profiles, Mount localhost dirs, etc.
