Policy Roast: The FCC's IoT Security Update Mandate and the Liability Gap
Mandating security updates without defining who pays when they fail creates more risk than it solves.
Policy Roast: The FCC's IoT Security Update Mandate and the Liability Gap
An FCC Commissioner floated a proposal to regulate IoT security updates. The goal: force manufacturers to patch vulnerable devices instead of abandoning them. The problem: the proposal mandates updates but punts on who's liable when they brick devices, introduce new vulnerabilities, or fail to deploy.
Regulation that creates obligations without defining accountability doesn't reduce risk. It just relocates it to whoever has the weakest legal team.
What the Proposal Does
The FCC is considering rules that would require IoT device manufacturers to:
- Provide security updates for a minimum number of years after sale.
- Disclose the end-of-support date at purchase.
- Notify consumers when critical vulnerabilities are discovered.
- Deliver patches through automated update mechanisms.
The intent is sound. IoT devices (routers, cameras, smart locks, medical devices) routinely ship with vulnerabilities and receive zero post-sale support. Consumers buy a "smart" device that becomes an attack surface the moment the manufacturer stops caring.
Where It Breaks
The proposal addresses vendor neglect but ignores the second-order risks that patching creates:
Who's liable if an update bricks the device?
Force a manufacturer to push patches, and you're forcing them to remotely alter hardware consumers own. If a firmware update kills a pacemaker, insulin pump, or industrial controller, the manufacturer will argue they were complying with an FCC mandate. The FCC will argue they only required reasonable efforts. The victim's estate will sue both.
Who defines "critical" vulnerability?
The proposal requires notification for "critical" flaws but doesn't define criticality. Is it CVSS 9.0+? Actively exploited? Exploitable over the internet? Exploitable locally? Every manufacturer will interpret this differently, and every plaintiff's attorney will argue their client's injury came from a flaw that should have triggered notification.
Who pays for infrastructure to deliver updates?
Small manufacturers can't afford to run update servers indefinitely. The proposal doesn't fund that infrastructure, so compliance becomes cost-prohibitive for anyone who isn't Amazon, Google, or Apple. That doesn't make consumers safer. It just consolidates the IoT market into vendors big enough to absorb compliance costs.
What happens when a manufacturer goes out of business?
The proposal mandates support for "a minimum number of years," but companies fail. Who patches devices from a bankrupt manufacturer? The FCC hasn't answered. In practice, this means devices become e-waste the moment a startup runs out of runway, regardless of the regulatory mandate.
The Liability Transfer Problem
Every security mandate transfers risk. The question is whether it transfers risk to the party best positioned to manage it.
Under the FCC proposal:
- Manufacturers bear the cost of building update infrastructure, testing patches, and maintaining support teams.
- Consumers bear the risk of bricked devices, update failures, and abandoned products from failed companies.
- Critical infrastructure operators (hospitals, utilities, industrial facilities) bear the risk of mandatory updates disrupting production systems.
None of these parties asked for this risk, and none of them have leverage to negotiate it. The FCC is imposing obligations without funding mechanisms, liability caps, or safe harbors. That's a recipe for expensive compliance theater and predictable litigation.
What Reasonable Regulation Would Look Like
If the FCC wants to fix IoT security without creating a liability minefield, the rule needs:
- Safe harbor for good-faith patching. If a manufacturer follows NIST guidelines, tests updates in staging, and provides rollback mechanisms, they shouldn't face strict liability when a device fails. Incentivize best practices, not perfection.
- Sunset provisions tied to device lifecycle. A $30 smart bulb doesn't warrant 10 years of support. A $50,000 medical device does. Mandate support duration based on device criticality and price point, not one-size-fits-all timelines.
- Escrow requirements for update infrastructure. If you sell IoT devices, fund an escrow account that survives bankruptcy. When you fail, the escrowed funds pay for a third party to deliver security updates. This solves the "who patches abandoned devices" problem.
- Clear CVSS thresholds for mandatory notifications. Define "critical" vulnerability as CVSS 9.0+ with active exploitation or 7.0+ if the device handles health/safety functions. Remove the interpretive wiggle room.
- Opt-out for critical infrastructure. Hospitals and utilities should be allowed to decline automatic updates and manage patching internally. Forced updates in production environments cause outages. Let operators choose risk vs. uptime.
Why This Matters Beyond IoT
The FCC's IoT proposal is a preview of how AI regulation will go wrong.
Both domains involve: - Rapidly evolving technology - Vendors with asymmetric power - Consumers who can't evaluate risk - Critical infrastructure dependencies
If regulators mandate "AI safety updates" the way they're mandating IoT patches, expect the same problems: vague standards, unfunded mandates, liability dumped on whoever's closest to the harm.
The pattern is predictable. Regulation written without liability clarity creates compliance costs for vendors, litigation risk for users, and no measurable improvement in security. The FCC's IoT proposal checks all three boxes.
What Happens Next
The proposal is still in public comment. Industry groups will argue it's too expensive. Consumer advocates will argue it doesn't go far enough. The FCC will likely split the difference and issue a rule that satisfies no one.
Meanwhile, IoT devices will keep shipping with vulnerabilities, manufacturers will keep abandoning products, and consumers will keep buying "smart" devices that become dumb the moment support ends.
The proposal won't change that. It will just add litigation to the list of consequences.
