Protect your Wi-Fi
The most important part of your work-from-home setup is your Wi-Fi network.
Your network is the bridge that connects your devices with each other and the internet. If a bad actor were to gain access to your network, they can use this information to take over your devices and hold them for ransom, or steal your personal and financial information. They could also use this information to steal from your organization.
The first (and easiest!) step is to make sure your default administrative password and login for your router are changed. Many brands use common default credentials like “admin” and “password”, which make it easy for anyone to hijack their way in.
Other ways you can protect your home Wi-Fi
Enable WPA2 encryption
Encryption scrambles the information that your router exchanges with a device on your network, so only the device can see it.
This way, if someone is trying to sniff this data from outside your network, the data they get won’t make any sense.
Create a guest network
You should turn on your guest network and use that for all of your personal devices, like IoT (internet of things) devices, smart speakers, game consoles, children’s devices, and for anyone visiting.
Then, use your normal non-guest network only for work devices.
Replace old routers
Like all technology, older devices are less likely to get security updates from their manufacturer, and are more likely to have security vulnerabilities.
Replace routers every several years to take advantage of the latest security features and updates. You’ll also likely get improved Wi-Fi coverage!
Watch out for public Wi-Fi
The café might make a great latté but they aren’t cybersecurity experts (unless they took this course as well!) You have to assume that any shared, public, open Wi-Fi can put you at risk.
You should not use networks at cafés, hotels, and airports to access work documents or systems without additional protection, like a virtual private network (VPN).
If you do not have a VPN, but you do have a work phone, you can consider using it as a Wi-Fi hotspot to tether your laptop through a secure connection.
These can use a lot of data that your company has to pay for, so check with them first to see if your device allows it.
