Easy access to wireless connectivity is what powers mobile workforces. That makes it a great thing for countless growing businesses but may also become a vulnerability.
Unsecured WiFi
An unsecured WiFi connection is any connection that’s public, meaning it doesn’t require a password. These unencrypted connections broadcast like a radio frequency so that if they’re unencrypted, data is visible to anyone who knows how to look for it.
Common Forms of Hacking
- Wardriving: Hackers drive around looking for weak or unsecured Wi-Fi networks. They map the locations and record the networks’ names (SSIDs) and encryption settings.
- Pineapples: Hackers set up a Wi-Fi router (referred to as a pineapple) and give it a name that’s identical or very similar to a nearby business network. The pineapple may have a stronger signal or can block the legitimate network.
- Network Sniffing: Hackers monitor (sniff) Wi-Fi network traffic in search of usernames, passwords, and other personally identifiable information to steal.
Prevention
- Disable the Wi-Fi auto-connect feature on your mobile devices for greater control over when and where your devices connect.
- Use an ethernet connection instead of Wi-Fi whenever that option is available.
- Use a VPN (virtual private network) whenever you communicate into your business infrastructure from an unsecured network.
- Connect to networks with the strongest level of encryption. WPA2 is better than WEP and WPA.
How to Tell if It’s Unsecured
The best rule of thumb is to assume that all public WiFi is unsecured. While this might sound paranoid, in the world of hacking, you’re better safe than sorry! [bctt tweet=”Any IT defense is only as strong as its weakest point, and unsecured Wi-Fi may be just that.” username=”ensteptech”]
Keeping Data Secure
You can do a lot to protect yourself and your data by using common sense. For example, when connecting to public WiFi, avoid logging into any websites that you know aren’t encrypted. Be proactive and always have a backup and recovery plan in case your network or device is compromised.

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry’s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
