Cyber Security: Public Wi-Fi & VPNs

Free Wi-Fi is available in many public places, including coffee shops, airports, and hotels. While it’s convenient to have access to free Wi-Fi, it’s important to be aware of the risks associated with using it. Cyber-criminals can use free Wi-Fi to steal your personal information or infect your device with malware. One way to stay safe while using free Wi-Fi is to use a virtual private network (VPN).

By following the below cybersecurity best practices, you can protect your sensitive information and ensure a safer online experience.

1.    When connecting to public Wi-Fi networks, choose networks that are known, secure, and password-protected whenever possible.

2.    Make sure your device's firewall is enabled to provide an additional layer of security. Additionally, keep your antivirus software up to date to protect against potential malware or threats.

3.    Avoid conducting sensitive activities, such as online banking, shopping, or accessing personal accounts, when connected to public Wi-Fi networks. These networks may be vulnerable to eavesdropping and data interception.

4.    When browsing websites, make sure you visit those that use HTTPS instead of regular HTTP. HTTPS provides enhanced security compared to HTTP. To ensure you're on a secure site, look for a padlock icon at the beginning of the URL field.

5.    Consider using a reputable VPN service to encrypt your internet traffic and create a secure connection between your device and the internet. VPNs provide an extra layer of protection when using public Wi-Fi networks, making it more difficult for hackers to intercept your data.

6.    Before connecting to a public Wi-Fi network, verify with the establishment or venue that the network name (SSID) is correct. Cyber criminals may set up fake Wi-Fi networks with similar names to trick users into connecting to them.
