Wi-Fi Cyber Security : Avoiding Destructive Connections

A professional VPN service, a good antivirus and regular “cleaning” of your devices will make a hacker attack almost impossible. VPN providers such as RusVPN provide many security options, including military-grade encryption and “impenetrable” servers around the world.

How Does WiFi Works?

Wireless, or Wi-Fi, works in much the same way as regular two-way radio. A simple walkie-talkie works on the same principle, differing only in that much less data is transmitted during audio transmission than with a wireless Internet connection.

When the devices communicate with each other, the wireless router (router) and your device use to transmit and receive frequency data from 2.4 GHz to 5 GHz. The more data you need to send, the higher the frequency.

Theoretically, the amount of data that can be sent via radio waves is infinite, and only the length of the string limits the lower spectrum. Someday, the time will come when the technology of data transmission will go into the visible range, and we will receive communication through laser beams.

It will look strange in your living room or in a local bar, but it will certainly come in handy in space.

Wireless network

Modern wireless networks are actually connected by wires, and these wires require only a little less than with a normal connection to a local network. And although your device is not physically connected to the router, the rest of the system is connected to each other through wires. Microfiber cables are capable of transmitting huge amounts of data today with very high accuracy, without having a harmful effect on human health, so wires connect 95% of all networks.

And only at the very last section of the network, at a distance between your router and your device, is the connection wireless.

Cyber ​​defense in WiFi networks is needed in this most vulnerable part of the network. Wherever you connect to the Internet: at home, in the office, in a cafe or in another public place – everywhere you face various dangers, everywhere they try to collect your personal data and any other personal information.

WiFi spoofing

Today, spoofing has become one of the most common ways to fake connections that we are used to trust. For example, in your local cafe someone hid a modified microcomputer like Raspberry Pi, which is found by the same name as the usual WiFi name of this cafe, and even works with the same password. While the cafe employees will guess what is happening, the offender will be already far away, with all the personal data of the customers of this cafe.

It appears that the only way completely protect any attacks is to connect to the Internet by using a good premium WiFi VPN application for wireless access points, which encrypts all this data.

Wi-Fi Cyber ​​Security: The Basics

Individual cyber protection in WiFi networks should be systemic. The most important question while developing your cyber protection system in WiFi networks is where it would be used, by whom and how.

As a business owner, you can set up free Wi-Fi for your customers. People using your WiFi should know the name of your connection and be sure that it is a secure connection. Ideally, to connect all clients, you will need a VPN router, as well as control over those who can have Internet access.

A similar technique can also be used in a business where there are no incoming customers. But in this case, you should make sure that all IoT devices (Internet of things), such as printers and scanners, are connected to the Network in the same way.

At your office, WiFI should never be without a password. In addition, your password must be very complex and must be issued by your system administrator. And this password should not be written in huge letters on the wall, as is often done in many companies.

Finally, for your home system, it is best to combine cable and wireless. Thus, you can focus on which devices should provide multi-level protection, and which may be relatively open. It’s best to have your printers and other smart devices connected to the Web only through your primary devices, such as a desktop computer or laptop.

If it’s impossible to create such impassable areas in your security system, you will have to connect each device individually to the VPN, as well as provide a certain degree of cybersecurity for your IoT devices.

The myth of free WiFi

Concepts such as a free lunch or free drinks do not actually exist. And if someone provides you with a free Internet connection, then most likely he (or she) will require something in return.

When it comes to a cafe or bar, everything is pretty simple. You “sit” on your twitter or tinder, pouring sadness over with alcohol. Not the most sensible occupation, however, it does not threaten your personal safety too much.

Much more dangerous is “free WiFi” at bus stops, in transport, in dormitories or in public institutions. In such places, there is usually no one directly responsible for the security of these connections, so hackers often crack them.

Conclusion

If you want to safely use your devices on the Internet, good cyber protection on WiFi networks is a must. However, to protect yourself, it is not enough to rely only on software tools. To leave as little personal information as possible on the Web, you need to use certain tricks and even possibly change some of your habits.

If you are served by a premium VPN provider such as RusVPN, your devices will be protected from hacking, and your WiFi connection will be encrypted from any snooping. However, when sending your personal data over the Internet, always be careful.

And never reply to tempting letters from unfamiliar “Nigerian princes.”
