Security teams usually have a set process for hacked staff accounts, but it breaks down for service accounts, API keys and app tokens that run in the background. Recent breaches show attackers often got in with access that was issued for a job and then forgotten. The article argues organisations need a current inventory of these machine accounts and agreed rules for shutting them down quickly.

What to do

  1. Build an inventory of high-privilege service accounts, API keys and OAuth apps, recording the owning team and what would fail if each were removed.
  2. Pre-authorise by name who can approve immediate revocation of high-tier machine identities, even if it disrupts a service.
  3. Remove or rotate credentials and OAuth apps that are no longer needed, including those issued for finished projects.
  4. Confirm cloud audit logging is turned on for machine identities so that sign-in location and permission changes can be checked.
