How do smart home systems stay secure?

Security in smart home systems is actually a process that begins the moment devices connect to the internet. Most IoT (Internet of Things) devices prioritize cost and ease of use over minimizing security vulnerabilities during manufacturing, so default settings are often weak. For example, many cheap thermostats or cameras come with default passwords that users don’t change, inviting attacks from day one. Security flaws are usually addressed through updates released by the manufacturer, but unfortunately, these devices have short lifespans, meaning updates are often discontinued. So, which is more secure: a local network or a cloud-based system? Here, "security" isn’t just about the server side—it also depends on where the data is stored. Cloud-based systems can receive more frequent updates on central servers and have advanced intrusion detection systems, but sending data to a third-party server introduces risks. With a local network, data stays within the home, but the security levels of local devices vary by manufacturer. The safest approach is to keep devices on the local network as much as possible and isolate IoT devices carefully. For example, running your IoT devices on a separate VLAN, isolated from your main network, helps protect your primary network if an attack occurs. It’s also crucial to change default settings, keep track of security updates the manufacturer supports throughout the device’s lifespan, and, if possible, customize devices with open-source firmware like Tasmota.

Smart home systems should prioritize certified devices for security. It's also crucial to regularly update the firmware on IoT devices to patch vulnerabilities. I wonder if local networks or cloud systems pose fewer security risks?
