Business Security Overview: How To Prevent Wifi Hacks

Public Wifi is not Safe!


You may not know it, but how to prevent WiFi hacks while on a public network is a business imperative.  It’s never truly safe to surf the web on a WiFi network that you don’t recognize.  Imagine that you are on a business trip, and connect to that WiFi in the airport to get some last-minute email done for your boss.  No problem, right?

Wrong.  Public wifi has a series of risks that can expose you and your personal data (including your financial data) to hackers.  Even your company’s data can be visible to hackers who want to take advantage of it.  The bad guys can easily get your most personal data this way.  It’s as though you posted your bank account and social security number on a bulletin board in a restaurant.

Here are some of the ways that your computer can be taken advantage of:

Fake Site:

It’s easy for the bad guys to broadcast a site that looks real, but is completely false.  Just because the network is called “Atlanta-Airport” doesn’t mean that it’s a website that’s being broadcast by the real airport.  For the price of an inexpensive router, hackers can simulate a real network.  Once you log onto the site, the hacker can monitor all your traffic– including connections to banks and your employer.  Often, your computer will even log on automatically to these spurious sites.


If the network that you’re connected to is not protected with  encryption, it’s easy for hackers to slip malware on to your computer.  Many people think of malware as computer viruses, but these malicious programs can be much more.  They can steal your passwords and your keystrokes, long after you have left the public wifi network.

Spoofing and Sniffing:

There are special tools now that allow hackers review your unencrypted connection.  Again, their goal is to look at your traffic, capture your passwords, and attack your computer, your employer, and your bank accounts.

There are many other ways attackers can make use of an unencrypted connection to get your information and compromise your computer.



You probably feel overwhelmed.  Easy to do.  You may feel like its important, even critical, to be able to connect anywhere.  We’re all used to the “always on” culture for working and having fun.

Luckily, there is a very simple fix.  Technology has made us less secure, but then helped us with defenses. 

The best tool to use is a simple piece of software called a VPN.    A VPN creates an encrypted tunnel that protects your surfing at all times.  It’s easy, and it’s inexpensive.  PC Mag says “Everyone ought to be using a virtual private network, or VPN whenever they’re on a network they don’t control. Yet when PCMag ran a survey on VPN usage, we found a surprising 71 percent of our 1,000 respondents had never used a VPN at all.”

Setting up a VPN is incredibly easy.  It’s as simple as buying a license, providing a login and password, and setting it up to run when the computer boots up.  It’s likely you won’t even know its running at all.

We use VPNs constantly at ItGresa.  We use them when we’re in the office, and we use them when we’re working on the road.  They’re easy, convenient, and cheap.
