Network Security

Whether you work remotely, travel frequently, or just love staying connected wherever you go, chances are you've  used a public Wi-Fi hotspot. Using these free Wi-Fi hotspots is super convenient, allowing you to access online accounts, catch up on work, and  check emails while on the go. But these networks aren't perfect and could leave you vulnerable to  cyberattacks.

Some dangers of public networks

• Man-in-the-middle attacks - One of the most common threats on these networks is called a man-in-the-middle (MITM) attack. When a computer makes a connection to the internet, data is sent from point A (device) to point B (service/website), and vulnerabilities can allow an attacker to get in between these transmissions and “read” them. So what you thought was private no longer is. 

• Wi-Fi snooping and sniffing - Wi-Fi snooping and sniffing is exactly what it sounds like. Cybercriminals can buy special software kits and even devices to help assist them with eavesdropping on Wi-Fi signals. This technique can allow the attackers to access everything that you are doing online — from viewing whole webpages you’ve visited (including any information you may have filled out while visiting that webpage) to being able to capture your login credentials

• Malicious hotspots - Malicious hotspots, also known as rogue access points, trick victims into connecting to what they think is a legitimate network because the name sounds reputable. Say you’re staying at the Goodnyght Inn and want to connect to the hotel’s Wi-Fi. You may think you’re selecting the correct one when you click on “GoodNyte Inn,” but you haven’t. (Note the capital N.) Instead, you’ve just connected to a rogue hotspot set up by cybercriminals who can now view your personal information.

Some tips for using public Wi-Fi

• Avoid accessing sensitive information - When using a public Wi-Fi network, it’s best to avoid accessing sensitive information. If you need to get online to browse for directions or do something else that’s less sensitive, you can probably do it. But if you’re trying to pay your bills or buy something, it may be best to wait.

• Stick to “HTTPS” websites - Only browse websites that include an SSL certificate while on public Wi-Fi. A website has an SSL certificate when the URL begins with “HTTPS.” Website addresses that start with “HTTPS” are encrypted, adding an extra layer of security and making your browsing more secure. If you connect to unsecured Wi-Fi networks and use “HTTP” instead of “HTTPS” addresses, your traffic could be visible to anyone else on the network.

• Use Multi-factor authentication - When you’re using public Wi-Fi, cyber snoops could gain access to your passwords. One way to enhance your protection is by enabling Multi-factor authentication (MFA) on any services that offer it. When enabled, this ensures that even if someone gains access to your password while you’re using public Wi-Fi, they still won’t be able to access your accounts. Usually, you’ll receive a second login step — a call or a code on your smartphone, for instance — that you’ll use to log in to your account.

• Turn off file sharing - Make sure you turn off file sharing before accessing public Wi-Fi. If you keep file sharing on, your folders may be  accessible to anyone connected to the same public network, allowing a hacker to get their hands on your private information without your permission.
