Most households today use some form of internet of things (IoT) technology, whether it’s a smartphone, tablet, smart plugs, or a network of cameras and sensors. Learning that nearly 120,000 home security cameras were compromised in South Korea and misused for sexploitation footage is enough to make anyone reconsider adding connected devices to their living space. After all, the home is meant to be a private and secure environment.
Although all smart homes carry some level of risk, widespread hacking incidents are still relatively uncommon. Cybercriminals targeting smart homes tend to be opportunistic rather than strategic. Instead of focusing on a particular household and attempting to break into a specific system, they scan broadly for devices with weak or misconfigured security settings that can be exploited easily.
The most effective way to safeguard smart home devices is to avoid being an easy target. Unfortunately, many of the hacking cases reported in the media stem from basic security oversights that could have been prevented with simple precautions.
How to Protect Your Smart Home From Hackers
Using weak passwords, neglecting firmware updates, or leaving Wi-Fi networks exposed can increase the risk of unauthorized access—even if the overall threat level remains low. Below are key steps homeowners can take to strengthen smart home security.
1. Use strong and unique passwords
Hackers gaining access to baby monitors and speaking through two-way audio is often the result of unchanged default passwords. Weak or reused passwords are easy to guess, especially if they have appeared in previous data breaches. Each smart device and account should have a strong, unique password to make attacks more difficult and less appealing.
2. Enable two-factor or multi-factor authentication
Multi-factor authentication adds an extra layer of protection by requiring a second form of verification beyond a password. Even if login credentials are compromised, attackers would still need additional approval. Many major smart home platforms, including Amazon, Google, and Philips Hue, support this feature. While it may add a small inconvenience during login, the added security is well worth the effort.
3. Secure your Wi-Fi network
Wi-Fi security is often overlooked but plays a critical role in smart home protection. Using WPA2 or WPA3 encryption and changing the router’s default password are essential steps. Limiting who has access to your Wi-Fi network also helps. Creating separate networks—one for personal devices and another exclusively for IoT devices—can further reduce risk by isolating smart home hardware from sensitive data.
4. Keep device firmware updated
Manufacturers regularly release firmware updates to patch newly discovered vulnerabilities. Enabling automatic updates ensures devices receive these fixes promptly. Keeping firmware current is one of the simplest and most effective ways to close security gaps.
5. Disable unnecessary features
Features that aren’t actively used can create additional entry points for attackers. If remote access isn’t needed, disabling it can significantly reduce exposure—particularly for devices with cameras. It’s also advisable to turn off Universal Plug and Play (UPnP) on routers and decline unnecessary integrations or permissions that don’t serve a clear purpose.
6. Research brands before buying
Brand recognition alone doesn’t guarantee strong security. Even well-known companies such as Wyze, Eufy, and Google have faced security issues in the past. Before purchasing a smart device, it’s important to research the brand’s security practices, data protection policies, and real-world user experiences. If features like local-only storage are important, they should be verified through reviews, forums, and independent evaluations.
Smart homes offer convenience and efficiency, but they also demand responsibility. By following basic cybersecurity practices and making informed purchasing decisions, homeowners can significantly reduce risks and enjoy the benefits of connected living with greater peace of mind.
