How does a Zscaler administrator troubleshoot a certificate pinned application?

Show Suggested Answer Hide Answer
Suggested Answer: A

Certificate pinning prevents SSL interception by validating a server's certificate against known values. When ZIA performs SSL inspection, it substitutes the certificate with one signed by Zscaler's CA. This causes the handshake to fail for pinned applications. To troubleshoot, an administrator should review SSL logs to identify handshake failures, which indicate certificate pinning issues. Logs will show the TLS negotiation details, including any disruptions.

I remember practicing a question about troubleshooting SSL issues, and I think inspecting the ZIA Web Policy could be relevant too, maybe option C?

I think option A makes sense since SSL logs can show issues with the handshake, but I'm not entirely sure how to access those logs.
