Is My Fridge Conspiring Against Me?
We all get a little paranoid about our gadgets occasionally. The “Is my phone listening to me?” entry has over a billion search results on Google alone. While your smart fridge isn’t plotting a grand conspiracy, it can still pose a significant security risk if not properly secured.
Many IoT devices have evolved much faster than the security systems they rely upon. Every connected device represents a potential entry point to your home or office network. Well-motivated hacker can gain access to your network through a random insecure lightbulb, and from there, find their way to other more critical gadgets, like a security camera.

How to Secure IoT Devices: Protecting Hardware, Software, and Communication Layers
Security with layer upon layer, like a good Lasagna
Securing your IoT devices isn’t just about installing the latest antivirus software or changing your passwords regularly—although those are important first steps. IoT security requires a comprehensive approach that addresses vulnerabilities across all layers: hardware, software, and communication.
Hardware Layer: Many IoT devices are designed with accessibility in mind, using common connectors like USB for easy setup and debugging. However, this can also make them easier to tamper with. Ensuring that the physical design of your devices limits access to internal components is essential to preventing unauthorized physical intrusions.
Software Layer: IoT devices run on various operating systems, apps, and firmware that need constant updates to patch vulnerabilities. Using the latest versions of software and regularly updating firmware with secure, encrypted versions helps maintain the integrity of your devices. Changing those default passwords and adding security rather than the easiest option is the key here.
Communication Layer: The data exchanged between IoT devices and the cloud must be encrypted using robust cryptographic methods like SHA, AES, or RSA. However, doing this on a purely software-based solution can be inefficient on low-power applications. A better approach involves embedding encryption functions directly into the device’s hardware, ensuring security without sacrificing performance.
FIDO2 provides the answers
With so many potential vulnerabilities to deal with the fact is that hardware-based cyber security remains superior. FIDO standard (Fast IDentity Online) comes into play as a newcomer and the top-of-the-line choice. The latest FIDO2.1 provides a strong, public-key cryptography-based authentication method that can be integrated into IoT systems. With FIDO each device can be equipped with a unique digital identity, making it nearly impossible for hackers to spoof or clone. This ensures that only authorized users and devices can access your network, adding a vital layer of security to your IoT ecosystem.
And yes – IoT ecosystem is what most of us have built around our homes and businesses without even noticing it. That printer, that new fridge, those security cameras that one company installed some time ago, or simply that WLAN booster you had to get to have your WLAN available all around. Now may be a good time to look into how all this is protected, before the hackers do it for you.
