You probably don’t realize it, but some of the simple things you do on the web everyday could be putting you and your computer at risk. In the case of online security, what you don’t know can hurt you.
Here are a few common online activities that could potentially make you vulnerable.
1. Using public Wi-Fi networks
We all do it, but that doesn’t mean it won’t get us into trouble. Using public Wi-Fi, especially in crowded places like coffee shops and airports, can open you and your computer up to a number of attacks.
When you think you’re connecting to “Free WiFi” at your hotel, you could actually be connecting to a fake network designed to capture your passwords and other information when you try to login. In cases where you need to use a public network consider using a Virtual Private Network (VPN), which will encrypt your data and give you the security of your own wireless network over a public connection, to keep your information safe.
2. Filling out online forms
While you certainly need to be careful with how you connect to the web so your information isn’t stolen, you need to be equally careful about what information you pass out to third parties.
Many websites collect information about online activity and turn around and sell it without your permission. Before passing out things like your email address, physical address, or phone number make sure you know exactly what a site plans on doing with it. The same goes for logging into third-party sites using your Facebook account. Sure, that single login makes it easier to use a new service, but it can come back to bite you. Be sure you know what you’re agreeing to before you pass along personal information.
3. Using the same password
Passwords can be tough to remember, but it pays to have a different password for every service you use. Particularly when it comes to things like banking information and email, you want to make sure you’ve selected a secure, unique password that would be hard for others to figure out.
Why? Security breaches happen. Passwords can get stolen. Think about it like this: If your house key was stolen, you wouldn’t hand over the keys to your car and office as well, right? Having unique passwords ensures that even if someone is able to access one of your accounts, they won’t be able to get into anything else with the same credentials.
4. Sharing photos on social media
From snapshots of puppies posted on Facebook, to pictures of epic turkey sandwich lunches blasted out on Twitter, most of us share photos online. What you may not realize, however, is that your phone might be geotagging these pictures, giving others the ability to pinpoint exactly where you were when you took them.
An easy solution to this problem is to turn off geotagging on your smartphone. If you’d like to keep the feature, when sharing a photo online be aware of where the photo was taken,and strip the location data off of an image that might have been taken at a sensitive spot.
5. Blindly accepting privacy policies
“If you have children who might use the site or service, such as Facebook, it's important to look up how the company treats data created by your child. It's also a good idea to familiarize yourself with the company's abuse policy, in case trolling or worse becomes an issue.”
Bottom line: Be smart, pay attention and be careful what you share when you’re online. You’ll be glad you did.
