SMART DEVICES AND SECURITY CONCERNS
Smart devices make our homes more convenient, comfortable and efficient. However, there are security concerns that can compromise your home or office network. Did you know that, when you issue a command to turn on a light or activate a switch using the manufacturer's app or your Google/Alexa assistant, that the command doesn't go directly to the device? The command actually is sent over the Internet to the company's servers and then is sent back to the individual device. Have you noticed, that when you set up a new device, you are asked by the app to connect to your home's router/gateway and input the password? This now means that the company that manufactured the device now has your home network's password stored on its servers.
This is placing a lot of trust in that company's security measures to prevent hacking. AND, if you buy cheaper Chinese imports, your information is now stored on servers in other countries that may not have adequate security measures. Should their servers be compromised, you now are at risk for hackers gaining access to your home computers, switches, cameras, alarm systems and electronic door locks.
HOW DO YOU GET AROUND THIS SECURITY VULNERABILITY?
Every home router/gateway not only has the main WIFI connections, but also has "guest" WIFI settings and connections. The guest network is separated from the main network in your home and has it's own password access. Therefore, anyone connected to the guest network is unable to see devices, computers and other networked items in your home.
So, when you get new switches, bulbs, cameras, locks or other devices, be sure to attach them to the GUEST network. Also, make sure that the GUEST network has a different password from your main network. This way, you are more protected from hackers gaining access to your home's network.
PASSWORDS AND PROBLEMS
After years of working with networks and helping others with their tech problems, I have seen a disturbing pattern of security vulnerabilities. Many people do not keep their antivirus software updated and some don't even have any installed on their phones, tablets or PCs! In addition, so many Windows users do not take the time to install security updates from Microsoft when notified. Finally, I have seen, time after time, users having the SAME password for multiple sites (especially baking/credit card sites) OR passwords that have common names, words or numbers attached to dates (i.e., using birthdates of children). These passwords are easily hacked because they are not random enough.
The common complaint is, "I can't begin to remember all these different passwords!"
Modern cellphones now have fingerprint or face recognition which can be used to set up access to various sites and apps on the Internet. This makes it easier because the user does not have to remember a password. In addition, many sites now have two-step authentication which will send an access code by text message to your phone. Take advantage of these tools to protect yourself.
If you are on a laptop or tablet, make use of password management software and apps. I have used "Last Pass" for years (BTW, I am not getting paid to mention this app). It is free for use on one device and has a small yearly fee if you want it to work across all devices.
With Last Pass, you only have to remember ONE password... the master password for the app itself. Each time you sign in to a new website or application, you can opt to have Last Pass generate a random password OR use your own password which will be saved in its database. Once saved, every time you return to that website, you can automatically login without having to type anything. Last Pass will do it for you. Take advantage of the password generator - set the parameters for at LEAST 12 characters, upper and lower case letters, numbers and wildcards. The tougher you make it for hackers, the more likely they will move on to someone who has used their child's name and birthdate.
Nothing is fool proof - take home alarm systems - if a thief wants to get into your home, they will stay determined even with an alarm system. However, the average thief will steer clear from alarmed homes and break in to homes without an alarm. But, the harder you make it for them to gain access, the less likely you will be compromised.
FINALLY, buy an antivirus program for your devices!!! Most publishers offer subscriptions for multiple devices for a nominal fee. When you are reminded to update the virus database, DO IT. And, I have a special word to Apple users: it is true that Apple keeps tight control on the apps that are available through their app store. However, if you install third-party apps, you put yourself at risk. Get an antivirus for your Apple laptops and computers - nothing is invulnerable.
Windows users: If you have a PC with Windows 10, you MUST upgrade to Windows 11 by October 2025. Security updates and support for anything Windows 10 or older will stop. Yes, it may be a hassle, especially if your PC is not compliant for Windows 11 (the new OS takes advantage of newer hardware that has tighter security), but if you are a heavy user and access financial and other critical information, you need to be aware of the security risks.
With a little planning and having the right tools, you reduce your risk of being hacked and your private information stolen or taken for ransom (ransomware scrambles your info and you have to PAY the hacker to have it unlocked). Remember: your credit cards are protected from purchase liability if they are stolen - BUT, if a hacker gains access to your financial institutions, you can lose your entire life savings with little to no recourse.
