MSP FAQ: standing SP secrets ≠ federated workload identity

Long-lived service-principal client secrets — especially shared across customer tenants — are standing credentials. Prefer workload identity federation / managed identities with short-lived tokens. Soft Auris m2m lifetim

Long-lived client secrets are not fixed by bot MFA

Bot MFA on an automation account does not remove a standing secret blast radius.

MSP FAQ: standing SP secrets ≠ federated workload identityMSP FAQ: standing SP secrets ≠ federated workload identityClaimSourceCheck
Claim, source, and the check that would change the conclusion.

Never share one SP across customer tenants; bind identity to tenant scope.

Distinct from offboarding and break-glass FAQs earlier today.

FLAG unverified benches/$/assertions where present; defensive guidance only; no PoC; no draft banners.

Map owners before any change: control-plane owner, customer-tenant owner, written rollback approver.

Prefer primary sources from this cycle — vendor PSIRT, CVE/NVD, CISA KEV, engineering posts — over secondary digests.

Authenticated inventory beats hostname spreadsheets: capture version, exposure path, and business owner.

Shrink blast radius first: remove public admin exposure, separate management networks, revoke standing secrets.

Patch only with vendor-supported builds; calendar removal dates for temporary workarounds in the same ticket.

  • Verify with non-exploit health checks — version endpoints, config dumps, authenticated status APIs — never PoC payloads.
  • Customer notes must separate confirmed facts from FLAG vendor benches, valuations, or unverified assertions.
  • QBR evidence includes ticket IDs, before/after versions, approvals, and residual risk with an owner.

  • On-call runbooks need trigger, owner, SLA, rollback, and one proof command that does not reproduce an attack.
  • If compromise is plausible: rotate credentials, rebuild from known-good images, treat restore paths as production admin.
  • Multi-tenant MSP tools need server-side tenant binding on every data path; client headers alone are not isolation.
  • Non-goals: no exploit steps, no bypass recipes, no invented rankings or MRR, no restamp of earlier packs from today.
