INCOMING MESSAGE SECURITY · Workflow idea

Make sure an incoming service message is genuine before acting on it.

Place an origin check before a process handles messages received from an external service. Accept only messages with valid proof from the expected source, and keep rejected or uncertain messages out of business actions for an authorized owner to review.

01 / The starting point

A clear request.
A useful direction.

A message received from an external service for a defined business purpose

“Check the message’s proof of origin against the expected source and pass it forward only when the check succeeds.”
An example request · Make it specific to your team.

02 / The work

6 tasks.
One useful outcome.

Helps protect an organization from acting on messages that may have been sent by an unknown or misleading source.

  1. Receive a message before any business action

    Keep the origin check at the start of the handling process, before a message can update records or prompt a response.

  2. Check the expected source proof

    Compare the supplied proof with the private verification material for the intended external source.

  3. Reject missing or invalid proof

    Stop messages that cannot be verified and keep them separate from messages that pass the origin check.

  4. Review verified message contents

    Check that the event type, key values, and intended customer or record are expected before relying on the message.

  5. Approve consequential follow-up

    Require an authorized person to approve customer-data changes, external communication, or other consequential actions.

  6. Keep a limited security record

    Record verification outcomes without exposing private verification material or retaining unnecessary message contents.

03 / The result

Something useful.
Something to build on.

A verified message ready for its intended process, or a rejected message held for security review without triggering downstream work.

The handoff

A verified message ready for its intended process, or a rejected message held for security review without triggering downstream work.

Keep in mind

A passing origin check does not prove that every message value is safe or correct. Reject missing or invalid proof, protect private verification material, and validate the message’s contents and intended effect before it can change customer information or trigger a consequential action.

04 / Make it yours

Set the brief.
Set the standard.

A few choices shape the work around your team.

Identify the expected message source

Document which external service may send messages and what kinds of events the organization accepts.

Protect verification material

Store private origin-check information in an access-controlled setting and restrict it to authorized maintainers.

Define rejection and review handling

Choose how failed checks are stopped, who investigates them, and what limited context is safe to retain.

Test valid and invalid examples

Check genuine, altered, missing-proof, and unexpected-event examples and confirm that failed checks cannot affect business records.
