Which of the following Vault policies will allow a Vault client to read a secret stored at secrets/applications/app01/api_key?

Show Suggested Answer Hide Answer
Suggested Answer: C

Comprehensive and Detailed in Depth

This question requires identifying a policy that permits reading the secret at secrets/applications/app01/api_key. Vault policies use paths and capabilities to control access. Let's evaluate:

A: path 'secrets/applications/' { capabilities = ['read'] allowed_parameters = { 'certificate' = [] } }

This policy allows reading at secrets/applications/, but not deeper paths like secrets/applications/app01/api_key. The allowed_parameters restriction is irrelevant for reading secrets. Incorrect.

B: path 'secrets/*' { capabilities = ['list'] }

The list capability allows listing secrets under secrets/, but not reading their contents. Reading requires the read capability. Incorrect.

C: path 'secrets/applications/+/api_*' { capabilities = ['read'] }

The + wildcard matches one segment (e.g., app01), and api_* matches api_key. This policy grants read access to secrets/applications/app01/api_key. Correct.

D: path 'secrets/applications/app01/api_key/*' { capabilities = ['update', 'list', 'read'] }

This policy applies to subpaths under api_key/, not the exact path api_key. It includes read, but the path mismatch makes it incorrect for this specific secret.

Overall Explanation from Vault Docs:

''Wildcards (*, +) allow flexible path matching... read capability is required to retrieve secret data.'' Option C uses globbing to precisely target the required path.

D gives full access, which is what we need for that secret.

I’m a bit confused about the allowed parameters in A. Does that affect the ability to read the secret? I’m not sure if it’s relevant here.

Okay, I've got a strategy for this. I'll break down each policy option and consider which one most specifically grants read access to the secrets/applications/app01/api_key path.
