In the past, VPN (\u00a0<\/a>Virtual Private Network\u00a0<\/em><\/a>)<\/a> was a tool that was created with the aim of connecting networks between office buildings securely and being able to use office networks from home or other places.<\/p>\n

Meanwhile, at this time, VPNs have been widely used by internet users around the world.\u00a0The goal?\u00a0Sure to get a connection to the Internet in a safe, private (\u00a0private\u00a0<\/em>), and can access a remote network.<\/p>\n

In this article you will get a complete explanation of what a vpn is and its functions as well as other things about VPNs that you must know.<\/p>\n

What is a VPN?<\/h2>\n

\"vpn<\/p>\n

VPN (\u00a0Virtual Private Network\u00a0<\/em>) connection is a service that gives you access to the website are safe (\u00a0secure\u00a0<\/em>) and private (\u00a0private\u00a0<\/em>) by changing the connection point through server and conceal data exchange occurs.<\/p>\n

Simply put, a VPN connects smartphones, tablets, PCs to another computer (commonly called a VPN Server) somewhere that is connected to the internet, and allows you to browse the internet using a computer internet network.<\/p>\n

So if the computer (server) is in a different country, it will be the country you are using when the internet tries to hit you through that connection and you can access something that you cannot access from your country.<\/p>\n

To better understand what a VPNs is, let’s review how it works.<\/p>\n

How VPN work?<\/h2>\n

\"vpn<\/p>\n

After knowing what a vpn is and its function, then you should also know how a VPN works.<\/p>\n

The way a VPNs works is that it encrypts the data exchange even before the public connection at the coffee shop or internet cafe reads it. Connecting to the internet using a VPNs connection is like accessing the internet using a special tunnel, not using the main network.<\/p>\n

The VPN server is in charge of forwarding your connection to the site you want to access.\u00a0So the connection you make will be recognized as a connection from the VPN server network not the network in use at that time.<\/p>\n

So when using a network without a VPNs, the connection is made directly ( direct\u00a0<\/em>) without encryption.\u00a0Meanwhile, if you use a VPN, the connection is encrypted and is passed through the VPN server first.<\/p>\n

The following is an illustration of a connection through a network without a VPNs and using a VPNs.<\/p>\n

This connection has indeed become the standard used when we use the internet.\u00a0There is no encryption and all the data involved in the process of exchanging data between you and applications on the internet can be seen by many people.<\/p>\n

It doesn’t matter if the data processed is only data regarding searches on Google, entertainment or something like that.<\/p>\n

This will be a problem if the data being processed is online banking, business email, or anything a little more sensitive.\u00a0Of course this would be a different story.\u00a0To carry out online attacks, hackers usually use the\u00a0Man in The Middle\u00a0<\/em>(MITM)\u00a0attack technique\u00a0this will be discussed another time.<\/p>\n

Then, how does a VPN work to secure data when exchanging data on the internet?\u00a0Let’s look at the image below.<\/p>\n

When you use a VPN (usually using an application), your data is encrypted by the application and only sent through the ISP then to the VPNs server. The VPN server becomes the third device to connect you with online sites or services.\u00a0It will be able to solve the problem of data privacy and security when exchanging data.\u00a0What are the other benefits and uses of a VPNs?<\/p>\n

Benefits of a VPN<\/h2>\n

There are several benefits that you can get when you use a VPNs, such as remote access\u00a0<\/em>.\u00a0Remote access allows us to access the internet using the office network, from anywhere as long as we are connected to the internet.<\/p>\n

So even if you use an external network, when you use a VPNs, your network can be recognized by the internet<\/a> using an office network. Apart from that, the following are some of the benefits of a VPN:<\/p>\n

1. ByPass<\/h3>\n

You can bypass geo-restrictions on streaming or video sites.\u00a0For example by the government to access sites that are considered dangerous, and so on.<\/p>\n

2. Data Security on Public Networks<\/h3>\n

Another benefit of a VPNs is that it protects your data exchange from untrusted WiFi or networks. This will be helpful when using public networks in cafes, bars, and the like.<\/p>\n

3. Secure Personal Information Anonymously<\/h3>\n

VPN hides your location in realtime ‘live’.\u00a0So, not just anyone can find out where you are when accessing.\u00a0Usually the detected location is where your VPN server is located.<\/p>\n

4. Data Encrypted<\/h3>\n

When processing data exchange between you and the online web application, your data is encrypted.\u00a0So even if someone sees what the computer sends, they only see encrypted information, not raw data.<\/p>\n

5. Encrypt Device Information<\/h3>\n

Someone cannot easily identify the device you are using, or what you are doing.<\/p>\n

VPN Pros and Cons<\/h2>\n

In addition to hiding real identities, VPNs can also limit browsing history by ISPs and governments.\u00a0However, there are some drawbacks to using a VPN, one of which is the sometimes slower connection.\u00a0Following are the advantages and disadvantages of a VPN.<\/p>\n\n\n\n\n\n\n\n
EXCESS<\/strong><\/td>\nDEFICIENCY<\/strong><\/td>\n<\/tr>\n
Data confidentiality is more secure.<\/td>\nSlower connection.<\/td>\n<\/tr>\n
Can access blocked websites.<\/td>\nUnstable connection.<\/td>\n<\/tr>\n
The real IP identity is not immediately known.<\/td>\nManual configuration is quite complicated.<\/td>\n<\/tr>\n
Access network from different locations.<\/td>\nThere are usage limitations.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Is it Safe to Use a VPN?<\/h2>\n

Security is sometimes a debate between employees and IT companies.<\/p>\n

A VPN can make your connection very secure, but it also depends on the protocol (road) you use to connect.<\/p>\n

Security using a VPNs is still hindered by two main factors, namely:<\/p>\n

1. Technology Limits<\/h3>\n

Limitations of the technology used to develop a VPN, such as the type of protocol and encryption used.<\/p>\n

2. Legal Limits<\/h3>\n

Legal and policy constraints affect what can be done with the technology.\u00a0The same applies to the laws of the countries where the servers and companies providing the VPN are located.\u00a0Sometimes the company’s own policies affect the way companies implement this technology in their services.<\/p>\n

So you could say that using a VPN is not completely safe.\u00a0However, at least using a VPN will be safer than using a regular connection.<\/p>\n

What Does a VPN Hide?<\/h2>\n

Using a VPN hides your real IP address and encrypts your internet connection.\u00a0But what is it really like in real life?<\/p>\n
