## Experiment Scope

It specifies the scope of the experiment. It can be `Namespaced` scope for pod level experiments and `Cluster` for the experiments having a cluster wide impact. It can be tuned via `scope` field.

Use the following example to tune this:

## Experiment Permissions

It specify the minimum permission that is required to run the ChaosExperiment. It also helps to estimate the blast radius for the ChaosExperiment. It can be tuned via `permissions` field.
