  1. I have 4 sessions namely Default, Extended, Programming and Supplier session.
  2. The jump to supplier session will happen via extended session. Default -> Extended -> Supplier
  3. But before jumping to Supplier session I need to provide security access.
  4. Once the security access is provided then only the jump should happen to Supplier session.

As per the ISO 14229 - 1 document the security access service is NOT applicable in default session but it is APPLICABLE in Non-Default session. So does it mean security access can be applied between 2 non-default session?

You can configure security level basically for every diagnostic service, even subservice (like for specific DIDs). What I understand you want to do is to require security level for changing into Supplier session, which is definitely possible to configure.

In my opinion, There is no security level required to enter any session. To perform any action in any session other than default, we need security level. Example : 1. To execute any service 2. To Read/write a DID
