Three Essential Security Practices Every IoT Manufacturer Must Adopt

With the Internet of Things becoming the most dynamic battleground for cyber threats, devices ranging from smart thermostats to connected cars are expanding convenience but also exposing new attack vectors. Hackers can harvest corporate data, commandeer thousands of devices into botnets, or even trigger emergency sirens, as seen in Dallas.

Security teams struggle to keep pace with the velocity of emerging vulnerabilities. A Google Project Zero researcher recently uncovered a flaw in Broadcom Wi‑Fi chips that could allow remote code execution on iPhones, Nexus devices, and Samsung smartphones simply by proximity. Another researcher identified 40 zero‑day vulnerabilities in Samsung’s Tizen OS for smartwatches, phones, and TVs—describing the code as the worst he’d ever seen. Meanwhile, the latest Mirai botnet variant can launch application‑layer attacks, eclipsing traditional DDoS capabilities and darkening large swaths of the internet.

Industry initiatives like Microsoft’s Sopris project aim to remediate IoT security by redesigning Wi‑Fi microcontrollers, yet manufacturers must adopt scalable internal practices to address the threat landscape effectively.

#1: Embrace Accountability

Many firms venturing into IoT are not rooted in technology and may overlook security in their design process. Vendors must acknowledge that connectivity inherently increases vulnerability exposure and that failing to do so endangers not only customers but the wider internet ecosystem.

#2: Enable Automated Updates

Devices lacking a mechanism for automatic firmware updates become immediate liabilities. When products hit the market with Mirai‑level vulnerabilities, the only viable remedy is a replacement—leading to costly recalls and customer churn. Historical examples, such as Windows XP’s ten‑year lifecycle that still required manual patching, illustrate the long‑term cost of neglecting updates. Conversely, Nest’s $10/month maintenance fee funds a robust update pipeline, enabling one of the safest IoT ecosystems today.

#3: Foster Transparent Vulnerability Disclosure

Manufacturers should provide a clear, publicly accessible channel—such as an email address or web form—for ethical hackers to report findings. Establishing a structured vulnerability disclosure policy, and optionally a bug‑bounty program, encourages independent scrutiny and accelerates patching cycles. No IoT product is infallible; widespread adoption of these practices is essential to protect privacy and maintain trust.

Adopting these three pillars—accountability, automated updates, and transparent disclosure—ensures that IoT manufacturers can safeguard their devices, customers, and the broader digital landscape.
