 #### Secret Handling
 
-TBD: Unlike transfer feature, this idea doesn't require transfer of secert, but it may need to be discussed
-(We would need to go back to discussion around https://github.com/kubernetes/enhancements/pull/2849#issuecomment-962168202).
+Unlike transfer feature, this idea doesn't need to involve any transfers of Secert, therefore there will be no issue on Secret handling.
+From a populator, Secrets are only referenced through snapshots that exist in the same namespace (As commented [here](https://github.com/kubernetes/enhancements/pull/2849#issuecomment-962168202), depending on the driver implementation, there may be very little chance that some CSI drivers won't work well in a very rare situation. However, such drivers can avoid this issue separately, by turning off this feature, implementing their own populator, and so on).
 
 #### Security
 
-TBD: Use of `ReferencePolicy` should remove the risk, but it may need to be discussed
-(We would need to check again for [the original use case of Gateway APIs](https://github.com/kubernetes/enhancements/pull/2849#issuecomment-919107307), and review if there are any security risks).
+By using [`ReferencePolicy`](https://gateway-api.sigs.k8s.io/concepts/security-model/#2-referencepolicy), only allowed snapshots can be accessed beyond the namespace boundary (Please also see [original  discussion on security](https://github.com/kubernetes/enhancements/pull/2849#issuecomment-919107307)).
+Therefore, no malicious user will be able to access to prohibited snapshots.
