Seven families, chosen to describe where the failure sits structurally — not by the attacker’s technique.

  • What you can’t see, you can’t investigate. Logging that’s absent, too short-lived, or unreachable exactly when it matters.

  • Poorly established or poorly revoked trust boundaries: identities, sessions, service accounts, standing privileges.

  • The signal exists, but the process fails to turn it into action: triage, escalation, post-block verification.

  • No one has the mandate to make decisions during the incident: isolation authority undefined, plan never tested, scope of intervention unclear.

  • Essential external responders are discovered during the crisis instead of being lined up beforehand: insurance, legal counsel, service providers.

  • Failures specific to managed service environments, where the compromise of a shared access point extends the blast radius across multiple client environments.
