The Importance of Wi-Fi Security: Protecting Your Data on Public Networks

 

Whether travelling for work or just out and about running errands, Wi-Fi access has become a necessity, providing the convenience of internet connectivity in coffee shops, airports, hotels, and many other public spaces. However, this convenience comes with significant security risks. Public Wi-Fi networks, especially those that are free and open, can be a prime target for cybercriminals. Understanding these risks and knowing how to protect yourself from any criminal activity is important, but have you ever considered it so, before now?

This article will take a quick dive into the dangers of using public Wi-Fi, and provide tips for staying safe.

 

The Risks of Using Public Wi-Fi Networks

Public Wi-Fi networks are inherently less secure than private ones, primarily because they are open to anyone within a particular range. Here are some of the significant risks associated with using public Wi-Fi and ways in which hackers can exploit public Wi-Fi:

  • Data Theft – Cybercriminals can intercept data transmitted over public Wi-Fi networks using techniques like man-in-the-middle (MITM) attacks. In these attacks, the hacker positions themselves between your device and the network, capturing any data sent or received. This can include login credentials, financial data, and personal information. It sounds far-fetched, we know – but it’s a real problem, and it does happen!
  • Fake Wi-Fi Hotspots – Hackers often set up fake Wi-Fi hotspots, known as “Evil Twins,” which mimic real networks (e.g., “Starbucks Free Wi-Fi” instead of “Starbucks Wi-Fi”). These fake networks are designed to trick users into connecting, allowing the hacker to intercept and monitor all internet traffic. They can capture all sorts of data from usernames, passwords, credit card details, and more.
  • Malware Distribution Public Wi-Fi networks can also be a common target for malware distribution. Hackers can look to exploit your device’s software to install malicious software (malware). This malware can then steal data, monitor your activities, or even take control of your device!
  • Unencrypted Networks Many public Wi-Fi networks do not use encryption, meaning data transmitted over the network is sent in plain text. This makes it much easier for hackers to intercept and read the data – think passwords or other login credentials.

 

Tips for Staying Safe on Public Wi-Fi

While the risks are quite significant, there are steps you can take to protect yourself when using public Wi-Fi networks:

1. Use a VPN

A Virtual Private Network (VPN) encrypts your internet connection, making it much harder for anyone to intercept your data. When you connect to a VPN, all your internet traffic is routed through a secure server, protecting your information from prying eyes. VPNs are especially important when accessing sensitive information, such as online banking or confidential work emails. If you travel with a work device, this is something to look into, to keep your, and your customer’s/clients information safe.

2. Avoid Sensitive Transactions

If you do need to jump on and access public Wi-Fi – we would strongly recommend you avoid accessing sensitive information or conducting financial transactions. It would be much safer to wait until you are on a secure, private network to perform these activities. If you must access sensitive data, ensure you are using a secure connection (sfG Tech Tip: look for “https” in the website’s URL).

3. Disable Automatic Connections

Many devices are set to automatically connect to available Wi-Fi networks. This can be convenient and save time when out and about or moving from location to location – but also risky. We would recommend that you turn off automatic connections and manually select trusted networks to ensure you are not inadvertently connecting to a malicious hotspot without even realising it.

4. Keep Software Updated

Regularly updating your device’s software is crucial for maintaining security – that goes for laptops, or mobile phone devices. Software updates often include patches for security vulnerabilities that could be known and used by hackers. We talk more about software updates in one of our blog articles, here.

5. Use Two-Factor Authentication (2FA)

Anyone who reads our monthly blogs will likely be familiar with 2FA – we’re big fans of it here and strongly advise everyone to have this enabled, for many security reasons and not just Wi-Fi related. Enable two-factor authentication (2FA) for your online accounts whenever possible. 2FA adds an extra layer of security by requiring a second form of verification (such as a text message code) in addition to your password. This can help protect your accounts even if your login credentials are compromised.

6. Recognise Fake Wi-Fi Hotspots

Be cautious when connecting to public Wi-Fi networks. Verify the network name with the establishment providing the Wi-Fi, and avoid networks with generic names like “Free Wi-Fi” or “Public Wi-Fi.” If you see multiple networks with the same or similar names, it’s safer to avoid them unless you can check which one is the ‘real deal’ with the owners.

Conclusion On Wi-Fi Security

While public Wi-Fi networks offer a lot of convenience, they do also pose security risks. By understanding these risks and taking steps to protect yourself, you can safely enjoy the benefits of wireless connectivity!

Testimonials

Abbie McCahill

“As a small team, time at work can be quite precious so when there’s a glitch with a laptop or a computer, it can really be a nightmare. Prior to us having sfG Software to support us, if one of the laptops was playing up, I’d invariably get asked to look at it and the downtime involved would usually be significant. Now, we pay sfG a very reasonable monthly retainer and if anything goes wrong with any of our equipment, we’re all safe in the knowledge that we can pick up the phone to or raise a ticket with one of the experienced engineers and the problem will be sorted out with minimal disruption. I really wouldn’t hesitate to recommend sfG to any customers or associates and I’m really grateful to have sfG Software as an extended arm of our team! Thanks again for supporting us so well!”

Louise Allen

“We started working with sfG in December 2011. We had been used to a very personal and responsive service from a sole trader, but we had outgrown this service and went out to tender. sfG won the tender convincingly, offering a blend of the personal approach we’d been used to and the capabilities and expertise of a bigger organisation.

We had a number of network issues that needed to be addressed, and we completed these within the first year of our partnership with sfG. They guided us through this work and achieved a good balance between letting us get on with what we could do for ourselves and stepping in to help. This allowed us to keep costs to a minimum, whilst ensuring that the work was carried out efficiently and effectively, with minimum disruption to the business.

They have been generous with their knowledge and we are developing our own competency through working in partnership with them. They provide us with an ongoing monthly support service, through which they carry out regular monthly updates and monitoring remotely.

On the occasions we have needed advice or attention on site, they have responded in a timely manner, appropriate to the severity of the problem. Our network is now much more robust and our support costs are predictable and well managed. We have found all the members of the sfG team a pleasure to work with.”

“We have been working with sfG for a number of years now, and have found their service to be attentive and efficient. Nothing is too much hassle, and if they can’t do something they are happy to make a recommendation for someone who can. Their pricing is great and, unlike some companies, we have never had a bill for “extras” that weren’t discussed before a project. All in all, a great bunch of guys to work with.”

David Brookfield

“My experience of IT support companies was that they were broadly all the same and all very mediocre. Since moving our business to sfG I have changed my view entirely.

The changeover from our previous providers was seamless and since then the support we have received has been excellent. The personnel at sfG are very easy to speak to. We receive almost instant responses to our needs and help is provided even if the issue isn’t directly within their remit.

We are kept up to date with our usage and spend via the monthly activity reports which provide excellent statistics for our Board and all at a very competitive price. sfG are certainly a cut above the norm in the IT Support industry.”

Sarah Fowler

“We’re a small charity that has muddled by without any formal IT support for many years, with frustrations and glitches ever growing! Our IT had really started to hold us back and interfere with our day to day work. It took around a year from us initially contacting sfG for us to finally take the leap and enter into an SLA. During that time they were incredibly patient, understanding and always happy to answer any questions we had. We’ve now made the move to Office 365, supported by sfG every step of the way. There’s lots still to do but they’re happy to work with us, at a pace that suits the team, so everyone can get used to changes gradually and avoid any additional pressures. I have no hesitation in reccommending sfG.”

“In short, we are absolutely delighted with the service provided by sfG and I would strongly recommend them for your own business.

sfG also made us aware of a programme offering donated technology products to UK charities from partners such as Microsoft and Cisco.

You could say that this saving alone has paid for our IT support service for the next 2 or 3 years!”

Daniel Murdoch

“We have been with sfG for just over a year now and their customer service has been first class from the first minute.  Initially, we probably weren’t their ideal client as we were just starting out, however during the first year of a business, the last thing you want to be worrying about is IT.  With a number of new employees and systems coming in throughout the year, sfG have been on top of all our needs and requirements.  Their response to any issue or query is within minutes and any issues which do arise are resolved well within their SLAs.  Their charging structure is very fair which sees us never overpaying for support which we don’t require or use throughout the year.  The team are all very friendly, personable and are quick to come and see us in person if required.”

“Without the help and support from sfG, I would still be staring at a screen now scratching my head.
The support they offer is above and beyond normal.
Extremely friendly staff, very understanding.
We required a specific bit of work done for our company and Andy was extremely helpful and did work behind the scenes that was outstanding.

The work he did will now save us hours of work.”
