What is VPN: Online Privacy and Security Guide

Maintaining privacy and security online is more important than ever in today's digital age. A virtual private network is an essential tool for this. This article will cover VPN technology, which creates a secure, encrypted connection between your device and the Internet. In this comprehensive VPN guide, you will learn about the different types of VPNs, the benefits of using one, and how to choose and set up the right VPN for you.

VPN Technology Overview

In the following sections, we will provide an overview of VPN technology, including a definition of the technology, a description of how it works, its importance, and key components in modern Internet usage.

What is VPN

A virtual private network (VPN) is a technology that provides a secure, encrypted connection over the Internet between a device and a network. Virtual private networks protect private web traffic from surveillance, interference, and censorship. Created to securely connect remote workers and corporate networks, VPNs are now widely used by everyday Internet users to enhance their online security and privacy.

How VPN Works

A virtual private network works by routing your device’s internet connection through a selected VPN server instead of your internet service provider (ISP). This masks your IP address and effectively hides your online identity. A virtual private network extends your corporate network by encrypting traffic between your device and the network. This ensures that traffic remains private as it travels, allowing employees to work outside the office and securely connect to the corporate network on smartphones and tablets. This encryption ensures that even if data is intercepted, it cannot be read or tampered with.

VPN Importance in Modern Internet Usage

In today’s internet landscape, a VPN is indispensable, as it provides a critical layer of security, especially when using public Wi-Fi networks that are often unsafe. A virtual private network helps protect sensitive information and personal data from cybercriminals. Additionally, a VPN helps users bypass geo-restrictions, allowing them to access blocked or regionally restricted content. This is especially useful for accessing streaming services, social media platforms, and websites that are otherwise inaccessible due to geo-restrictions.

VPN Key Components

The main components of a VPN include a VPN client, a VPN server, and secure tunneling protocols.

• A VPN client is software installed on a user's device that establishes and manages a VPN connection.
• A VPN server is a remote server that the client connects to, acting as a gateway to the Internet.
• Tunneling protocols such as OpenVPN, L2TP/IPsec, and IKEv2/IPsec create a secure and encrypted connection. These protocols ensure the privacy and integrity of data transmitted over the VPN.

By integrating these components, a VPN provides a secure and private connection, protecting users from potential online threats and maintaining anonymity.

How VPN Protects Your Data

A virtual private network protects your data through a combination of encryption methods, tunneling protocols, and VPN technology, which can enhance user anonymity by masking their IP address.

VPN Encryption Methods

VPNs use robust encryption methods to protect your data. Encryption converts your data into a secure code that can only be decrypted with the appropriate key. This helps to prevent access to your data by unauthorized persons. Most virtual private networks use complex encryption protocols such as AES-256, which provides a high level of security and ensures that sensitive data such as login credentials, financial data, and personal messages are not stolen and are protected from interception.

VPN Tunneling Protocols

Since tunneling protocols create an encrypted connection between your device and the VPN server, they form the basis of VPN security. OpenVPN, L2TP/IPsec, and IKEv2/IPsec tunneling protocols are the most common. PPTP is considered the standard protocol for creating VPN tunnels, but it needs to be updated. Due to the low level of data protection, it is becoming a thing of the past, although Microsoft has repeatedly released updates. Switching to other technologies is recommended – L2TP/IPsec is much safer. These protocols protect your data from eavesdroppers by creating a secure "tunnel". Each protocol has its advantages. OpenVPN is known for its balance of speed and security, while L2TP/IPsec and IKEv2/IPsec provide reliable encryption and stability.

Top 6 VPN Encryption Protocols

In this section, we offer a list of virtual private network encryption protocols with a brief description of the characteristics of each VPN protocol.

• SSTP

SSTP is a protocol built into Windows by Microsoft. It appeared in the Vista SP1 OS version (2008). According to some experts, it easily bypasses most firewalls but has backdoors.

• IPsec

IPsec is a set of protocols used in VPN technology to ensure data protection. It encrypts transmitted IP packets and allows for authentication. Some argue that IPsec's disadvantages can be hidden precisely behind the encryption algorithms.

• L2TP/IPsec

This protocol is often used as an alternative to OpenVPN when there is no need to solve global problems. The L2TP protocol only provides tunneling, so it is used with IPsec, responsible for encryption. It is safe and easy to configure but slower than OpenVPN.

• IKEv2/IPsec

IKEv2 tunneling protocol from IT industry giants Cisco and Microsoft. The advantages of IKEv2/IPsec include automatic reconnection to the network after a connection break, and the disadvantages include a limited number of compatible platforms.

• OpenVPN

The most popular VPN protocol. It is considered a perfectly balanced technology in terms of security and performance. Supports AES and BlowFish cryptography. Both encryption algorithms are highly reliable, but the second is considered faster.

• WireGuard

The WireGuard protocol competes with OpenVPN and is equal to it in some parameters. This protocol is considered secure due to its smaller "surface" of attacks but is still not as flexible due to the lack of a choice of encryption method. The advantage of WireGuard is its speed: several tests have shown that it works faster than OpenVPN.

IP Anonymity and Masking

In addition to encryption and secure tunneling, a virtual private network allows users to remain anonymous by masking their IP address. When you connect to a VPN, the IP address of your actual computer is replaced with the IP address of the VPN server. This makes it more difficult for websites, advertisers, and other organizations to track your online activities and determine your physical location. A VPN protects your identity from targeted advertising or location-based tracking by masking your IP address. This anonymity is vital for maintaining privacy, especially when users are concerned about surveillance or censorship.

VPN Types

The following sections present the 3 main types of VPNs and their descriptions:

• Remote Access VPN
• Site-to-Site VPN
• Personal VPN

Remote Access VPN

A remote access VPN allows users to connect to a private network remotely. These devices, whether laptops, tablets, or smartphones, are endpoints where advances in VPN technology enable security checks to be performed to ensure they are authorized before connecting. When an employee uses a remote access VPN, their device appears as if it is on the same local network as the company. This allows them to securely access internal company resources such as file servers, printers, and databases. It also ensures secure communications and data transfer, which is especially useful for remote workers or employees who travel frequently. Remote virtual private networks use encryption to protect the data transmitted over the connection from potential interception, ensuring that sensitive company information is kept safe. Therefore, companies often use this type of VPN to provide employees with secure access to the company's internal network from anywhere in the world.

Site-to-Site VPN

A Site-to-Site VPN, also known as Router-to-Router VPN, connects all the necessary networks over the Internet. Companies with multiple branches or offices often use this type of VPN, which allows them to create a secure and encrypted connection between their geographically separated networks. For example, a company with offices in different cities can use a Site-to-Site VPN to connect the networks of all its offices. This ensures seamless communication and resource usage connected to a single local network. Site-to-Site VPNs can be used for intranets, where multiple offices of a single company are located, or extranets, where several companies' networks are connected. Network routers or dedicated VPN devices usually manage this mode, and it works well for providing secure inter-office communications.

Personal VPN

A personal VPN is designed for people who want to improve their online security and privacy. Unlike remote access and Site-to-Site VPNs, personal VPNs are typically used for personal internet use rather than accessing specific internal networks. They allow users to bypass geo-restrictions, encrypt their internet traffic, and hide their IP addresses. This is especially useful for accessing regional content, protecting public Wi-Fi networks' data, and preventing ISPs or websites' tracking. Personal VPN services are widely available and often come with user-friendly apps allowing users to connect and disconnect from the VPN with a single click. This type of VPN greatly protects everyday internet use, helping users protect their data from cyberattacks.

VPN Benefits and Use Cases
