Stay Safe Using Public Wi-Fi

Usage of devices in public areas it is like some kind of cult today. We all use our iPhones and iPads for “check-in” and surf the internet wherever we are. We are daily checking our emails and always looking for free hot-spots connection.

How often you share photos, videos and location being on concert, sport event or with friends? We think daily. Unbeknownst to you, there might be someone stealing your login info right as you press the return key. After all, it’s an open network at a coffee shop—anyone has access to your information.

But, luckily, there’s a way to protect yourself. We will explain how people obtain your personal information on an unsecured network and how to prevent them from doing so.

Why connections in public areas are dangerous?

The main danger is that anyone from hacker to an average user can access the network through all public, unencrypted, or open network that also means that any of these people can access what you transmit to and from the router, or access point.

The difference between public networks and your home connection is that you know everyone who use your own network, because you give them the password. With a public network, you can’t know for sure that the person sitting next to you isn't trying to steal your login cookies or just searching for other confidential information.

Rather than mask the problem by using something like HTTPS plugin, we will show you how to patch it completely. You don’t need to stop using public Wi-Fi, just follow our tips and continue to share and surf.

#1 Download the Necessary Software

We all know that Macs are safe computers out of the box, but as soon as you connect to a network, you are vulnerable to local attacks. The problem is that OS X does not protect against the most minor threats, like local network packet interception. For that, you’ll need to download a proper software to mask your proxy through VPN to prevent attacks.

#2 Switch On Your Firewall

All versions of OS X have included a Unix-based firewall called ipfw. In security parlance, ipfw is a packet-filtering firewall: it checks each packet coming or going through the Mac’s network interfaces against a set of rules, and allows it to pass or blocks it.

Packet-filtering firewalls like ipfw classify network traffic two ways: by type, using port numbers, and by origin and destination, using IP addresses. For instance, a packet-filtering

firewall could accept file-sharing connections from IP addresses of your work network but not from other addresses on the Internet.

#3 Forget The Network

Once you are all done with your web browsing, make sure to log off any services you were signed into. Then, tell your device to forget the network. This means that your iPhone or Mac won't automatically connect again to the network if you're in range.

On Mac, head to System Preferences, go to Network, and under the Wi-Fi section click Advanced. Than untick "Remember networks this computer has joined". You can also individually remove networks by selecting the name and pressing the minus button underneath.

#4 Try to use HTTPS when it is possible

Like the old saying goes, check for the lock in your browser to make sure it's secure. One way you can force your browser to use HTTPS is through an extension, such as HTTPS Everywhere. It's important to note that HTTPS Everywhere works by activating encryption on all supported parts of the website.

#5 Keep your software up to date

Be sure that you use the latest version of browsing, cleaning and optimization software with all fixed bugs and latest changes. Just set up Update Tracker on MacKeeper to keep your software update daily.

#6 Use Safe Browsing

On top of that, the last one tip is to use Safe Browsing feature from Mackeeper to prevent the attack. With this simple real-time feature, you can safely surf the Internet knowing that all malicious websites will be blocked automatically. For extra security and convenience, you can manually create lists of potentially dangerous websites that will be auto-blocked.

Be sure if you will use at least one of this tips when you will next connect social network, share the photos or just “check in” through the public Wifi network it could be real barrier for hucker of theft to your information.
