Home technology is the technology a person runs in their own home: the internet connection that arrives at the wall, the Wi-Fi that carries it through the rooms, the security on their own phone and laptop, and the appliances that now come with an app. Unlike the technology in an office, no IT team looks after it. The family looks after it, often with help from the internet provider.
Think of an ordinary evening in a flat. A child joins an online class on a laptop. A parent watches a cricket match on the TV. Someone's phone rings with an unknown number. The washing machine finishes its cycle and sends a message to a phone. Each of these depends on a different layer of home technology. This page sorts them into three groups.
The first group is the home connection. A fibre cable from the internet provider ends at a small box on the wall, the home gateway. In most Indian homes, this one box both receives the fibre and sends out the Wi-Fi. If the signal does not reach every room, people add Wi-Fi routers and mesh systems. Many providers also run managed home Wi-Fi software on the gateway, so that their support team can check and fix the Wi-Fi from their office.
The second group is consumer cybersecurity: the security that a person buys or installs for themselves. It includes antivirus and security suites, a password manager, an app for caller ID and spam call blocking, and home security cameras such as a video doorbell. Most attacks on a family begin with phishing: a fake message or call that tricks a person into giving away an OTP, a password or money. So much of this software tries to warn the person before they act.
The third group is the smart home. A washing machine, a bulb or a door sensor is now a small computer. Each one runs firmware, the software on its own chip. The owner controls it from an app on the phone, and it connects to the maker's servers on the internet. This three-layer design is explained in IoT architecture. Low-power IoT wireless chips let small devices run for years on a battery.
The three groups depend on each other. Every smart device and every security app needs the home connection. And every device that joins the home network is one more device that an attacker could try to take over. For example, a camera that still has its factory password can be found and controlled from the internet. So one unprotected device can put the whole home network at risk.
