IoT devices are increasingly becoming an integral part of everyone’s life, be it professional or personal. - It’s crucial to be aware of the risks that comes with IoT devices - Please, stop using default as well as simple passwords - Have a rigorous patch management - More importantly, don’t underestimate the risks. Apply zero-trust approach everywhere. #DTalks

Here are key steps to enhance IoT security: 1. Conduct Regular Risk Assessments: Identify vulnerabilities in IoT devices and their configurations. 2. Update Firmware & Software: Keep all devices updated to patch known vulnerabilities. 3. Network Segmentation: Isolate IoT devices from critical systems to limit exposure. 4. Strong Authentication: Use robust, unique passwords and enable multi-factor authentication (MFA). 5. Disable Unnecessary Features: Turn off services or ports not in use to minimize attack surfaces. 6. Monitor & Log Activity: Continuously monitor IoT devices for unusual or unauthorized behavior. 7. Vendor Evaluation: Choose IoT devices from manufacturers with a strong security track record.

Securing IoT devices goes beyond basic steps. Based on my experience, an overlooked but critical measure is assessing the supply chain of IoT devices. Ensure your vendors follow secure coding practices and offer transparency on device firmware updates. Additionally, implement device identity management solutions to monitor IoT connections in real time and detect anomalies early. Finally, I recommend implementing Zero Trust principles. Treat every IoT device as untrusted by default, and enforce strict access controls and monitoring. Proactive strategies like these transform IoT from a vulnerability into an asset.

The answer is - they are not. IoT devices are commonly used by bad actors targeting a business because they are often unprotected and using default credentials. Yes, you should change default passwords. But upgrading firmware is not realistic at scale and can cause business disruption. Besides strong passwords, you should ensure the device does not have a direct path to the internet. Those two controls will provide the biggest bang for your control buck.

IoT devices often come with overlooked risks, such as weak default credentials, outdated firmware, or insufficient encryption, which can open hidden backdoors into your network. For example, smart home devices like cameras or doorbells are frequent targets for hackers seeking entry to more critical systems. Even trusted brands can be vulnerable if security patches aren’t applied promptly. The real question is whether these devices have been properly configured and whether your network is set up to detect and block unauthorised access. Without a thorough security review, your IoT devices might be opening up unnecessary doors.
