Own the Tripwire
Unused systems, accounts, files and tokens can expose intruders using valid logins and ordinary tools. CISA’s 16 September 2026 guidance describes tripwires, breadcrumbs and honeytokens: plausible bait detects contact, distracts and gathers threat intelligence, complementing Zero Trust and prevention.
Plan one internal canary, monitored separately. Specify the unexpected action, responder and evidence. This is a planning example, not a universal installation recipe.
- Pilot one discovery or access hypothesis; avoid scattered credentials.
- Exclude production secrets, customer records and real privilege; check onward access.
- Record authorised tests, scanners and maintenance for responders.
- Staff alert delivery, escalation and evidence collection; ignored mailboxes are insufficient.
- Authorise exercises through contact, delivery and triage; record expected results and gaps.
- Recheck ownership after migrations or staff changes; retire through change control, retaining records.
Agree monitoring scope, retention and privacy beforehand; avoid undocumented collection. Correlate alerts with independent identity, endpoint and network evidence; preserve records before changes. Contact establishes neither attacker identity nor incident extent. Silence proves no wider safety. Retain identity controls, logging and response.

Thank you for this practical piece; the test of “if the account nobody should use is touched tonight, will somebody know what to do next?” is a sharp way to judge a decoy strategy, and the reminder that a trap that stays quiet is not a clean bill of health is an important caution.
