What Security Measures Should I Always Take?
Whether you’re at work, home or out in public, here are some reminders to keep your PC as secure as possible at all times.
- Make sure your antivirus and anti-spyware software, firewalls and web browser are running and updated. Even your neighbors could be peeping into your home network.

See our review comparing ID theft protection services for more information about identity theft and how you can best protect yourself.

How Can You Ensure Your Public WiFi Safety?
There are a number of steps you can take to minimize the security risks when using public WiFi. To have the best WiFi hotspot safety, we recommend you take all of the following measures. And if you’re not using these resources (like file sharing) on your home network, there’s no advantage to having them enabled.
Turn Off File Sharing Settings
Windows PC
In Windows, you can find these settings at Control Panel > Network and Sharing Center > Advanced Sharing Settings.
- Change your network to Public.
- Make sure you turn off a) Network Discovery, b) File and Printer Sharing, c) Public Folder Sharing and d) Media Streaming.
- Choose 128-bit (or higher) file-sharing connections.
- Make sure you turn on password protected sharing.
- Don’t forget to save your changes!
Mac OS
In Mac OS X, you can find these settings at System Preferences > Sharing.
- Make sure all the settings are unchecked.
Then go back to System Preferences to go > “Security and Privacy” > firewall’s advanced settings.
- Turn off Network Discovery, which is called stealth mode.
Select Your Hotspot Carefully
Choose the most secure WiFi connection you can in a public setting. If you have a couple of options of coffee houses, for instance, go to the one that has better WiFi hotspot protection.
Bring Your Own Hotspot For Maximum Security
Tethering from your smartphone’s cellular connection is often more secure that signing onto a public WiFi network.
How can you tell which connection is more secure? The most secure is WPA2, followed by WPA and then WEP. Try to avoid networks listed as unsecure. Obviously, this security type leaves you the most vulnerable and is often a target by hackers.
On a PC: after you’ve clicked on the wireless network icon at the bottom right of your screen, all available networks will appear. If you hover over each Service Set Identifier (SSID), you’ll see the information about each SSID pop up, including the security type.
On a Mac: click on the WiFi icon on the top right menu bar and at the bottom of the network list, select “open network preferences.” (You can also get to it from “Network” under “System Preferences”). Select the WiFi network on the left column then click the “Advanced” button on the bottom right. On the WiFi tab at the top, it will show a list of your connections with the security column showing the type and if it’s a secure connection or not.
Be Prudent With Your Web Use
Choose the websites you visit carefully when using public WiFi. Go on reliable, known sites and avoid doing any online banking or paying bills in public. Also try to stick to HTTPS and SSL sites that provide encryption. Most browsers will display a lock or some other indication on the address bar to let you know the site’s encrypted.
Use A VPN
A VPN, or Virtual Private Network, is an excellent option if you want to go the extra mile to protect your online security. A VPN service allows you to use public WiFi with a secure, encrypted connection.
There are a number of VPN services online that are easy to install and inexpensive that can give you the added security you need — especially when using public WiFi access.
Read our comparison of the best VPN services for the top VPNs on the market, as well as things to look for that depend on your unique needs.
Kill the Public Network Once You’re Done
If you’re working in a public area, once you’re done with web browsing, you should log off any services you were previously signed into. The next step is to set your device to forget those networks. This way, your PC or phone won’t automatically connect again to that same network when you’re in range.
In Windows, you can:
Uncheck the “Connect Automatically” checkbox beside the network name; or
Go to Control Panel > Network and Sharing Center, click on the network name, click on “Wireless Properties,” and uncheck “Connect automatically when this network is in range.”
To drop a public network in Mac, it’s a little harder to find:
- Click on your WiFi icon and choose “Open Network Preferences.”
- Select WiFi on the sidebar and click on the “Advanced” button in the lower right corner of your screen.
- Go to the WiFi tab and select which network you want to kill.
- Click on the minus button, click “Remove” and then hit “OK.”
