How to Keep Your Mac Secure on Public Wi-Fi
Public Wi-Fi makes it convenient to stay online at the hotels, airports, or even shared workspaces. But are they secure enough?
Wi-Fi networks are vulnerable to security risk when you don’t know who operates it, who’s connected, or if it’s properly secured. Lucky for Mac users there are ways to protect themselves from risks and browse safely.
Why Public Wi-Fi Can Put Your Data at Risk
A public Wi-Fi hotspot isn’t inherently unsafe, but unlike your home or work connection, it can sometimes carry a threat. One reason for this is that you’re not completely sure who’s operating it. It’s also unknown which other devices are connected and if it’s been securely configured. For such reasons, some public Wi-Fi connections can’t be trusted.
Mac users can avoid security threats over Wi-Fi by connecting to recognized Wi-Fi networks only and keeping the macOS up to date. Firewall features should be enabled.
Watch Out for Fake Hotspots and Other Common Threats
Fake or lookalike Wi-Fi hotspots with a similar name of a cafe or airport are used to trick unsuspecting users. Similarly, poorly secured Wi-Fi connections can make information vulnerable to interception and be a threat to Mac users. Unknown devices connected to a public Wi-Fi hotspot can also compromise the network to target other users or automatically enable file and device sharing.
Protect your Mac with these simple rules. Confirm with the establishment if the Wi-Fi username and password are correct rather than automatically signing into a network that looks similar. Avoid dealing with sensitive data or entering information when connected to public Wi-Fi, do this when you know you’re connected to a private one.
Use a VPN on Public Networks
VPNs provide a secure connection when browsing on your Mac. It protects the internet traffic between your Mac and Wi-Fi hotspot even if it’s public. Although a VPN encrypts data transferred over a public Wi-Fi connection, it can’t prevent your Mac from every type of threat. Keep threats at bay by choosing a trusted provider for your VPN services, preferably one with a good reputation. Avoid lesser-known VPNs available for free, as they may not be able offer enough protection when using public Wi-Fi.
Check for HTTPS Before Entering Information
HTTPS stands for Hypertext Transfer Protocol Secure and it can be found at the beginning of a website’s address. It’s a communication protocol that encrypts the connection between your Mac’s browser and the website. This protects the information shared over the network. However, having an HTTPS protocol doesn’t mean that the website itself is trustworthy. Fake or phishing websites also operate under this guise, and Mac users are advised to check if they’re on the correct site before entering any details.
Check Your Mac Security Settings
A few simple settings on your Mac can reduce the risk while using public Wi-Fi.
Remove the public Wi-Fi networks you’ve used earlier. To do this go to Apple menu → System Settings → Wi-Fi. Then under Known Networks, you can remove unused networks. Make sure your Mac is running the latest version of macOS, go to System Settings → General → Software Update. Turn on Apple’s built-in firewall. To do this, go to System Settings → Network → Firewall.These basic steps can reduce the risks you Mac is exposed to without requiring any sort of advanced networking knowledge.
Avoid Sensitive Transactions When You Can
Public Wi-Fi can be used for web browsing, reading articles, or looking up general information. Although, users should avoid it for online activities like signing into personal accounts, online banking, and purchasing online. Mac users can hold-off sensitive transactions until they’re on a private Wi-Fi connection. If it’s something urgent then switch to mobile internet to complete the activity. You can also turn on the VPN for online activities that can’t be held off.
Check Online Services Before Entering Personal or Payment Details
Wi-Fi hotspot users can access online movies, songs, travel bookings, and other everyday needs. Although users should check if they’re on the correct website and if it’s secured by an ‘HTTPS’ connection before entering personal details. When conducting online transactions, it’s important to double-check the information a service asks you to provide.
For example, an online casino offering free chip no deposit offers may require personal identity information and online transactions. Since this involves providing sensitive data, users should take extra care to verify the website.
A Few Checks Can Make Public Wi-Fi Safer
Using public Wi-Fi for your Mac is convenient to stay online when you’re on the road or not at home. To stay safe when using public Wi-Fi, we recommend you connect with the correct Wi-Fi network and visit sites with optimal security. In addition to this, keep macOS up to date.
