Computer networks support your seamless access to shared company folders, e-mail, the internet, and software like Pastel.

Whether you’re working from home, on the move, or simply at the office, your work devices almost always need a network connection to ensure your optimal productivity.

But networks can also pose some dire threats to business cybersecurity, especially concerning data and privacy. In this article, learn four bad practices to avoid for smarter network security.

(1) Don’t Connect to Public Wi-Fi Hotspots

A Wi-Fi hotspot named “Free Guest Wi-Fi” or “Complimentary Coffee Shop Internet” might not be provided by your hotel or cafe. In fact, anyone can create a Wi-Fi hotspot with any name.

It can be difficult to identify the difference between a genuine hotspot and a bogus one – hence the name for this type of attack: The evil twin.

The evil twin is a hotspot that looks legitimate, but isn’t. When you connect your device to an evil twin, the attacker may access all the data that travels through the access point.

Hence, never connect to public Wi-Fi hotspots. Along with hotels and food outlets, these are also popular at airports and conference venues.

(2) Don’t Connect to Wi-Fi That Doesn’t Require a Passcode

When you connect to a Wi-Fi hotspot that doesn’t require a passcode, the traffic between your device and the access point won’t be encrypted. This means anything you do while connected to this network could be seen by others.

Your usernames and passwords might be intercepted and viewed by a snoop scanning local Wi-Fi traffic. To guard against this, only connect to a hotspot that requires a passcode. The passcode encrypts the traffic between your device and the access point and makes it more difficult for hackers to snoop on your data.

A virtual private network (VPN) can also protect against a local snoop. A VPN connection encrypts traffic from your device to a system elsewhere – from your laptop to a server at your company, for example. A local snoop would then need to first decrypt the data in order to access it.

(3) Don’t Use a Network Without Your Firewall Enabled

You use Wi-Fi or Ethernet to get information into your system – but networks work in both directions, i.e., a hacker can use the internet to access your computer directly.

A firewall protects your system from a remote attacker. They help ensure the only traffic entering or leaving your network is the traffic you want.

Therefore, ensure the firewall is always enabled on your device. It may have been turned off accidently, during a software update, or for online gaming, etc. Learn how to check your firewall status on Windows and Mac.

If you have a Wi-Fi router at home, check the manufacturer’s instructions to access the administrative settings. Update the router’s firmware, and verify that the router firewall is turned on. The good news is that most routers enable the firewall by default.
