That's a really practical point about "break glass" access. It's one of those controls that feels great to set up, but the process afterward is where most teams stumble.
I've seen the manual review loop fall apart because the alert for using the override goes to the same team that used it. There's no independent check. It works better when the justification log automatically creates a ticket for a separate compliance lead to review, closing the loop.
And you're right, auditors don't just ask if the button exists, they want to see every single press accounted for.

The audit trail discussion here is really helpful. I'm also looking at IdPs in a similar context and had a question about that.
When you export those cryptographically verifiable logs for immutable storage, how do you handle the actual log review process? Is it purely for legal hold, or do teams actually set up alerts to scan them for anomalies?
This is absolutely the correct starting point. I've reviewed too many security questionnaires where the team lists a compliant IdP as a control, but their own application logs don't capture the user's IdP session identifier, breaking the forensic chain. The IdP's audit log becomes a silo you can't correlate.
Your point about mapping data flows first is critical. We performed an exercise where we documented every data store and API endpoint that could touch PHI, then worked backward to design the required policy enforcement points. In many cases, the application itself needed to enforce policy *after* authentication, based on context the IdP couldn't know. Treating the IdP as the single gatekeeper created a false sense of security.
The vendor comparison distraction is real. Draft your BAA requirements, specify your need for daily, machine-readable log exports with cryptographic integrity, and make that a non-negotiable line item in your RFP. Any vendor that can't meet that in writing is eliminated, regardless of their feature list.
>capture the user's IdP session identifier, breaking the forensic chain
This is the part that kills me every time. You can have perfect IdP logs, but if your application's data warehouse tables don't store that same session ID, you can't trace a bad query back to the human who ran it.
We solved this by making the session ID a required parameter in every backend service call and propagating it through our ETL jobs. Added it as a `created_by_session` column to every table that handles PHI. It's a pain to retrofit, but it's the only way to maintain the chain when someone needs to investigate a data access incident.
>Treating the IdP as the single gatekeeper created a false sense of security
Exactly. The IdP tells you who someone is, not what they should be allowed to do with specific data records. We implemented row-level security in Snowflake that evaluates both the user's identity AND the data context - something the IdP can't possibly know.
