WHAT IS A VPN

What is a VPN? VPN Definition

VPN stands for Virtual Private Network – it is a technology which establishes a secure connection. VPN encrypts your online traffic in real time, allowing you to establish a private connection to the Internet. You can choose your desired location and browse as if you were in another city, country or even another part of the world. This ensures a higher level of privacy as well as decreases exposure to cyber threats. Your Internet traffic travels through an encrypted tunnel and will look like it’s coming from the VPN server rather than your own IP address. This is very important especially if you are using a public Wi-Fi or a shared Wi-Fi connection. 

“A VPN acts like a digital middleman between you and the Internet.”

How does a VPN work?

When you’re connected to the Internet, all of your activity is logged and associated with your Internet Protocol or IP address. If you’re using a shared WiFi network, others on the network could see what you’re doing. Even on your home network, your Internet Service Provider (ISP) can still see your activity. Using a VPN is like creating a digital middleman between your device and the Internet that blocks others from seeing what you’re doing. When you connect to a VPN, instead of your activity being associated with your IP address, now it’s the VPN server’s IP address that is associated with your data. You might think of it like a return address: instead of the mail coming from your home address, it’s now coming from the VPN server’s “home” address.

The data that is sent and received when you’re online is also encrypted, so besides it not coming from your own IP address, it’s also unreadable. You could think of it like sending scrambled information through a secret tunnel, and it’s not readable until it reaches its intended destination on the other side. Even if someone were to intercept the message in the tunnel, without the key, they wouldn’t be able to decipher it. Without getting too technical, the important thing to remember is that with a VPN, data is encrypted as it enters the tunnel and it’s decrypted as it leaves the tunnel using encryption keys.

The process of establishing a VPN connection is relatively straightforward. When a user connects to a VPN server, the VPN client software on their device initiates a handshake with the server. During this process, the client and server exchange keys to establish an encrypted connection.

Once the connection is established, all data transmitted between the client and server is encrypted and cannot be intercepted by third parties. This includes data sent over public networks, such as Wi-Fi hotspots or cellular networks.

Why should you use a VPN connection?

“By using a VPN, people can’t figure out who you are, where you are, or what you’re looking at.”

A VPN service can provide many uses, such as covering your IP address from the prying address of trolls, hackers, businesses, and governments, whether you’re using a personal or public WiFi connection. Likewise, connecting to the Internet via a VPN’s encrypted server improves your security from such entities. An interesting benefit of changing your IP address is that you can change your location.

So, what is the purpose of a VPN? Well, not every person uses a VPN for the same thing. Here are a few common reasons people use Virtual Private Networks:

Remote working security 

It’s not a coincidence that cyberattacks have increased as more companies have embraced remote working. To shield remote workers from online attacks, many businesses are signing up for corporate VPN accounts. The good news for workers in this situation is that they don’t have to worry about paying for a VPN service, with their employers signing them up for one.

Public WiFi security 

While it’s convenient to use the Internet connection at the shopping mall, airport, restaurant or park, such connections can be less secure and vulnerable to a Man-in-the-Middle (MitM) or a fake WiFi hotspot attack. Using a VPN secures users from such attacks.

Video streaming 

Streaming platforms such as Netflix, Hulu, HBO, and others can limit access by your IP address. This isn’t ideal if you’re traveling or live in a country with limited entertainment options. By leveraging a VPN to spoof your location, you can circumvent geo-blocks and access different TV shows, movies, and even video games. 

Some gamers and streamers utilize VPNs to cover their IP addresses in the wake of escalating doxxing and swatting attacks. However, some gamers worry about the impact of a VPN on their gaming performance. So, does a VPN slow down internet speeds? The answer may surprise you.

Online shopping and banking

Payment platforms like PayPal may use geo-blocks to restrict access to users in certain countries, blocking legitimate users from their accounts, such as travelers. A VPN can help you bypass these blocks and access your account. A VPN may also help you get better deals from websites that offer different prices based on IP addresses.

Evading censorship 

Internet users in countries with restrictions on freedom of speech sometimes have success accessing censored content, such as news stories, with the help of VPNs. Citizens, activists, and journalists in nations with draconian laws also use VPNs to cover their tracks on the Internet and stay safe.

Concealing your actual IP address 

With the right tools, a curious entity such as a stalker, hacker, or online troll can find your general geographical location through your IP address. Covering your actual IP address with a virtual one protects your location. If you’re not sure what your IP address is and how to look it up – What is IP address. 

Spoofing your location 

Spoofing your location by using VPN servers around the world is an excellent way to confuse anyone spying on you. Whether it’s your government frowning at you for speaking your mind on the Internet or an advertising algorithm interested in where you’re connected from, location spoofing can throw snoopers off your back.

Secure transfer of data

Businesses are insisting that remote workers connect to corporate resources with VPNs for data security. A VPN’s end-to-end security protects sensitive data, such as intellectual property, from hackers.

Besides these benefits of using a VPN connection, employers often use VPNs to enable their employees to remotely access files and programs on a business network as if they were in the office. Additionally, some people use VPNs to bypass Internet censorship in certain countries, such as journalists or political dissidents who want to speak out safely while hiding their identities. 

The History of VPNs

Predecessors of VPNs

The concept of connecting remote devices over a network is not new. In the 1970s, the first wide-area networks (WANs) were developed, allowing organizations to connect computers across large distances. One of the earliest methods for remote connectivity was dial-up connections, where users would establish a connection with a remote server using a modem and a telephone line. This allowed users to access resources on a remote network, but it was slow, expensive, and not very secure.

In the 1990s, as the internet became more widespread, companies began to use leased lines to connect their branch offices to a central network. This provided faster speeds than dial-up connections, but it was still expensive and required a lot of maintenance.

Early VPN technology

In the late 1990s, a new technology called Virtual Private Networks (VPNs) emerged. VPNs allowed users to connect to a private network over the public internet, using encryption to keep their data secure. This made it much easier and more cost-effective to connect remote workers to a central network, as they could now use the public internet instead of expensive leased lines.

The first VPN protocol was called Point-to-Point Tunneling Protocol (PPTP), which was developed by Microsoft in 1996. PPTP allowed users to create a secure connection between their computer and a remote server, using a username and password for authentication.

Another early VPN protocol was Layer 2 Tunneling Protocol (L2TP), which was developed by Microsoft and Cisco in 1999. L2TP was a more secure protocol than PPTP, as it used encryption to protect data in transit.

Current VPNs

Today, VPNs are used by individuals and organizations all over the world to protect their online privacy and security. Modern VPNs use a range of encryption protocols, including OpenVPN, IPSec, and WireGuard, to create secure connections over the internet.

What are the Different Types of VPN

There are several types of VPNs, each with its own unique characteristics and use cases. The main types of VPNs are:

1. Remote Access VPN: This type of VPN is used by individuals or employees to connect to a company’s network from a remote location, such as a home office or a coffee shop. Remote Access VPNs use encryption and authentication to secure the connection between the user and the company’s network.
2. Site-to-Site VPN: This type of VPN is used to connect two or more networks together, such as a company’s headquarters and its branch offices. Site-to-Site VPNs create a secure and encrypted connection between the networks, allowing users to access resources and communicate with each other securely.
3. Intranet VPN: An Intranet VPN is used to create a private network within a company’s internal network. This type of VPN allows employees to access company resources securely and privately from within the network.
4. Extranet VPN: An Extranet VPN is used to create a secure and private connection between a company and its partners, suppliers, or customers. This type of VPN is used to share sensitive information securely between different organizations.
5. Mobile VPN: A Mobile VPN is used to provide secure and encrypted connections for mobile devices, such as smartphones or tablets. Mobile VPNs are often used by remote workers who need to access company resources securely from their mobile devices.
6. SSL VPN: An SSL VPN uses the SSL (Secure Sockets Layer) protocol to create a secure and encrypted connection between a user and a remote network. SSL VPNs are often used to provide remote access to web-based applications and services.

Choosing the Right VPN 

When it comes to selecting a VPN, it’s important to consider a few key factors. These include:

• Security Protocols: Look for a VPN that uses strong security protocols, such as OpenVPN or IKEv2, to ensure that your data is properly encrypted and protected.
• Server Locations: Consider the number and locations of servers available through the VPN. This can be especially important if you need to access content that is restricted in your location or if you want to optimize your connection for streaming or gaming.
• Logging Policies: Make sure to review the logging policies of any VPN you are considering. A no-logs policy is generally the most secure option, as it means that the VPN does not keep any record of your online activities.

How to use a VPN to change location

If you want to learn how to use a VPN to change location — simply connect to a VPN server with a different IP address than yours. You’ll appear to be connecting to the Internet from the VPN server’s location instead of yours, which can be a different city or country. Using this method, you can potentially unlock new entertainment content by bypassing geoblocks.

Can you trust a VPN connection

Using a VPN can provide an additional layer of security and privacy for your online activities, but whether or not a VPN is truly secure depends on several factors.The strength of the encryption used by the VPN provider is a critical factor. Most VPNs use a combination of encryption protocols to secure the connection between the user’s device and the VPN server. The most common encryption protocols used by VPNs are OpenVPN, IPSec, and WireGuard. These protocols use advanced encryption algorithms to ensure that the data being transmitted is secure and protected from prying eyes.

The privacy policy and logging practices of the VPN provider are also important factors to consider. A good VPN provider should have a clear and transparent privacy policy that outlines what data they collect from their users and how they use it. They should also have a no-logging policy, which means they do not store any information about your online activities or data transmitted through their servers.

The physical security of the VPN server is another important factor. A VPN server can be vulnerable to physical attacks or breaches if it is not properly secured. Good VPN providers like Malwarebytes take steps to secure their servers, such as using multi-factor authentication, firewalls, and other security measures.

Finally, it’s important to note that no VPN is 100% secure. While a VPN can provide an additional layer of security and privacy, it is still possible for a determined attacker to compromise a VPN connection. However, using a reputable VPN provider can significantly reduce the risk of such attacks.

Conclusion

In conclusion, using a VPN is an essential tool for safeguarding your online privacy and security. It allows you to browse the internet securely, without worrying about anyone monitoring your online activities. However, using a VPN alone is not enough to protect your online presence from cyber threats.

It’s also important to use reputable antivirus and internet security software to protect your device from malware and viruses. Additionally, being cognizant of cyber security threats, such as phishing scams and data breaches, and taking appropriate measures to protect yourself can go a long way in ensuring your online safety.

By combining the use of a VPN with other security measures, you can create a comprehensive approach to protect yourself online. Remember, the internet can be a dangerous place, but by taking the necessary precautions, you can surf the web with confidence and peace of mind.
