As more and more network connected devices enter our home life, the scope of hackers' attacks has begun to grow larger. Recently, we often heard the news that a certain networked outlet was attacked; some smart refrigerators were "black" and began to send spam; the cracked smart lock made it easy for thieves to burglary; the networked microwave oven became a "botnet" Part of it, launch a cyber attack on others; even your thermostat will be used by hackers to track your movements.
In order to prevent various digital attacks, it has become an urgent matter to improve the level of smart home security. The following eight tips can keep you away from hackers.
1, set the WPA2 password for wireless routing
Usually when setting the wireless network password, we can choose WEP, WPA and WPA2. If your encryption method is the first two, please change it to the last one immediately. WEP is a fragile encryption method that is easily cracked. Although WPA2 is not impregnable, it is much safer than WEP.
2. If conditions permit, establish two wireless networks.
If you have a dual-band router, remember to take advantage of it. You'd better set up a separate wireless network for all of the "Internet of Things" gadgets, and then put the payment device and some sensitive data on another network. This way, even if a hacker has captured your smart Light Bulb, they can't use it as a connection springboard to access other important data.
3, remember to give the wireless network a low-key name
Do not assign a wireless router to your default name or use a name such as "XXX (name) network". Network names with identity information are more likely to be cracked. Try 2ndAmendment4Life or NSA Surveillance Van, a name that makes hackers look headaches.
4, use strong password
We have emphasized it many times. Don't use simple passwords. A long list of random numbers, letters and symbols is the best password. If you are afraid of not remembering it, you can write it on paper and stick it on the refrigerator.
5, close the "guest mode" of the route
Turn off this feature on the route. Each wireless router is turned off in a different way. You may want to go to the search engine and enter "How to turn off the XXX (brand or model) routed visitor mode" to find it, or set it according to the product manual.
6, open the firewall
Although most computers are now pre-installed with firewall software and they are activated by default, you should check their status to ensure that the network is always protected. If you don't have any firewalls on your computer, please download and install one now.
7. Check all IoT devices in your home
This may take some time, but it is definitely worth doing. You need to know the ports, network protocols, and IP addresses of the various devices in your home, such as light bulbs, refrigerators, and game consoles. You should find this information on the support website of each device, or you can find them on the manual. Once you find out which devices require specific access rights, remember to enter the firewall to restrict the ports on those devices. There is no reason for any device to access the network freely and without constraints. Devices such as smartphones, tablets, and computers connected to IoT devices also need to be checked.
8, keep the firmware upgrade
Regular firmware upgrades are important because they keep your device away from known and potential vulnerabilities. It's best to set the device to update automatically, as most people forget to manually update the firmware.
If you are willing to spend an afternoon to get all of the above, then your smart home is already in good protection. If you feel that this is not enough, then you can consider purchasing a "Unified Threat Management System". Remember, you don't have to make your home the most unbreakable fortress in the world, just more protective than most homes - hackers will always choose the ones that are the easiest to get.
