Firewall security

Today, almost every apartment has a home network, which connects stationary computers, laptops, data storage (NAS), media players, smart TVs, as well as smartphones, tablets and other wearable devices. Either wired (Ethernet) or wireless (Wi-Fi) connections and TCP / IP protocols are used. With the development of IoT technologies, household appliances - refrigerators, coffee makers, air conditioners, and even wiring equipment - have entered the Network. Thanks to the Smart Home solutions, we can control the brightness of lighting, remotely adjust the indoor climate, turn on and off various devices - this makes life easier, but it can create serious problems for the owner of advanced solutions.

Unfortunately, the developers of such devices are not yet sufficiently concerned about the safety of their products, and the number of vulnerabilities found in them is growing like mushrooms after rain. There are frequent cases when after entering the market the device ceases to be supported - for example, in our TV, the firmware of 2016 based on Android 4 is installed and the manufacturer is not going to update it. The guests add problems: it is inconvenient to deny them access to Wi-Fi, but I would not want to let anyone into their cozy network either. Who knows what viruses can settle in other people's mobile phones? All this leads us to the need to divide the home network into several isolated segments. Let's try to figure out how to do this, as they say, with little blood and with the lowest financial costs.
