VPN-^(VPNs) ovi postaju popularni svakim danom. Dostupni su svima besplatno^{(for free)} i premium ako želite brze poslužitelje i bolju sigurnost. Možda ste čuli za VPN tunel^{(VPN Tunnel)} . No, jeste li se ikada zapitali što je to i kako funkcionira? Ovo je vodič za vas da znate sve o VPN tunelu^{(VPN Tunnel)} i uobičajenim^(Common) vrstama protokola VPN tuneliranja^{(VPN Tunneling protocols)} .

Što je VPN tunel

Obično, kada svoje uređaje povežemo s internetom putem WiFi -a ili Etherneta ili mobilnih podataka, naši se uređaji izravno povezuju s davateljima internetskih^{(Internet Service)} usluga bez ičega u sredini. Cijeli naš promet usmjerava se preko davatelja internetskih usluga.

No, kada se povežete s internetom putem VPN -a , niste izravno povezani s davateljem internetskih usluga. VPN djeluje kao posrednik između vašeg uređaja i davatelja internetskih usluga. Vaš cijeli promet i podaci sada su preusmjereni preko VPN -a i vaš davatelj internetskih usluga nema pristup tome. Veza koja se uspostavlja između vašeg uređaja i VPN - a naziva se VPN tunel. U većini besplatnih VPN usluga tuneli nisu ispravno šifrirani što ostavlja vaše podatke izloženima.

Uobičajene vrste ^(Types)VPN protokola^{(VPN Tunneling Protocols)} za tuneliranje

VPN tuneli su šifrirani pomoću različitih protokola koji ovise i razlikuju se od svakog davatelja VPN usluga. Svaka vrsta VPN tunela pruža vam određenu razinu sigurnosti i čini vaše podatke sigurnima. Kada koristimo VPN program na svom uređaju, ne moramo ništa učiniti. Te protokole za tuneliranje provodi VPN program. Postoji potreba da znamo koliko su sigurne naše VPN veze i koje protokole za tuneliranje koriste. Pogledajmo vrste VPN protokola za tuneliranje^{(VPN Tunneling Protocols)} .

Različite vrste protokola VPN tuneliranja su

1. PPTP ( protokol za tuneliranje od točke do točke^{(Point-to-Point Tunneling Protocol)} )
2. L2TP/IPsec
3. SSTP
4. OpenVPN
5. WireGuard

Pogledajmo što su oni detaljno.

1]  PPTP ( protokol za tuneliranje od točke do točke^{(Point-to-Point Tunneling Protocol)} )

PPTP ( protokol za tuneliranje od točke do točke^{(Point-to-Point Tunneling Protocol)} ) smatra se najmanje sigurnim protokolom za tuneliranje. Ujedno je i najstariji među protokolima. Stvorio ju je Microsoft i izdao uz Windows 95 . Za korištenje PPTP^(PPTP) -a ne morate imati nikakvo tehničko znanje . Sve^(All) što trebate je korisničko ime i lozinka s adresom poslužitelja za uspostavljanje veze. PPTP je također najbrži protokol VPN tuneliranja^{(VPN Tunneling)} jer je njegova razina enkripcije preniska. Ako se ne brinete o sigurnosti, ovo bi vam moglo odgovarati u smislu brzine.

2] L2TP/IPSec

Layer 2 Tunneling Protocol je bolji od PPTP -a u smislu sigurnosti i ne smatra se konkurencijom u smislu brzine. PPTP je brži od L2TP- a . Nema vlastitu enkripciju. Podaci i promet koji se odvijaju kroz ovaj tunel kriptirani su korištenjem Internet Protocol Security ( IPSec ). L2TP/IPSec pruža korisniku najnapredniju tehnologiju šifriranja, AES-256 . L2TP je popularan protokol zbog svoje visoke razine sigurnosti, ali ne može zaobići neke restriktivne vatrozide jer je koristio fiksne portove za povezivanje.

3] SSTP

^{(Secure Socket Tunneling Protocol)}Microsoft je također razvio Secure Socket Tunneling Protocol ( SSTP ) i koristi se s Windows Vista SP1 i novijim verzijama. Ima mogućnost prijenosa podataka putem Secure Sockets Layer ( SSL ). Otuda^(Hence) i naziv Secure Socket Tunneling Protocol . SSL osigurava podatke koji prolaze kroz njega s različitim portovima koji mogu zaobići većinu vatrozida. SSTP je izvorno podržan u sustavu Windows^(Windows) i nije dostupan ni na jednoj drugoj platformi. Čak se i protokol ne revidira javno zbog mogućnosti bilo kakvih ulaza u backdoor.

 4] OpenVPN

OpenVPN je open-source VPN protokol tuneliranja koji šifrira podatke koji prolaze kroz njega pomoću AES-256 kao što je L2TP . Razlika između njih dvoje je kod koji je otvoreno dostupan za revizije i svatko može pronaći ranjivosti i popraviti ih. To je razlog što se smatra najsigurnijim VPN protokolom za tuneliranje. Također, podržan je na različitim platformama i većina davatelja VPN usluga to koristi iz istog razloga. OpenVPN pruža brže veze i može zaobići gotovo svaki vatrozid.

5] WireGuard

Ovo je novi i najnoviji VPN protokol za tuneliranje koji ima za cilj biti brz, siguran, lagan i jednostavan za korištenje. To je protokol usmjeren na sigurnost koji koristi dokazane kriptografske protokole i algoritme za osiguranje podataka. WireGuard nije dostupan na nekim davateljima VPN usluga, iako je bolji u brzini i sigurnosti od OpenVPN -a jer je najnovija tehnologija i davatelji VPN usluga su u procesu uključivanja u svoje programe.

To su različite vrste VPN protokola za tuneliranje koje koristimo u VPN -u .

What is VPN Tunnel? Common Types of VPN Tunneling Protocols

VPNs are becoming popular with each passing day. They are available to everyone for free and premium if you want fast servers and better security. You might have heard about VPN Tunnel. But, have you ever wondered about what it is and how does it work? This is the guide for you to know all about VPN Tunnel and Common types of VPN Tunneling protocols.

What is VPN Tunnel

Normally, when we connect our devices to the internet via WiFi or ethernet, or mobile data, our devices directly connect to the Internet Service providers without anything in the middle. Our entire traffic is routed through the internet service provider.

But, when you connect to the internet through a VPN, you are not directly connected to the internet service provider. VPN acts as the middleman between your device and the internet service provider. Your entire traffic and data are now routed through VPN and your internet service provider has no access to it. The connection that establishes between your device and the VPN is called a VPN tunnel. In most of the free VPN services, the tunnels are not properly encrypted which leaves your data exposed.

Common Types of VPN Tunneling Protocols

VPN tunnels are encrypted using various protocols that depend and differ from every VPN service provider. Each type of VPN tunnel provides you with some level of security and makes your data secure. When we use a VPN program on our device, we don’t have to do anything. Those tunneling protocols are undertaken by the VPN program. There is a need that we have to know how secure are our VPN connections and what tunneling protocols are they using. Let’s see the types of VPN Tunneling Protocols.

The different types of VPN tunneling protocols are

1. PPTP (Point-to-Point Tunneling Protocol)
2. L2TP/IPsec
3. SSTP
4. OpenVPN
5. WireGuard

Let’s see what they are in detail.

1]  PPTP (Point-to-Point Tunneling Protocol)

PPTP (Point-to-Point Tunneling Protocol) is considered the least secure tunneling protocol. It is also the oldest among the protocols. It was created by Microsoft and released with Windows 95. You don’t need to have any technical expertise to use PPTP. All you need is a username and password with a server address to make the connection. PPTP is also the fastest VPN Tunneling protocol since its encryption level is too low. If you don’t bother about security, this might work for you in terms of speed.

2] L2TP/IPSec

Layer 2 Tunneling Protocol is better than PPTP in terms of security and not considered a competition in terms of speed. PPTP is speeder than L2TP.  It does not have its own encryption. The data and traffic that happens through this tunnel are encrypted using Internet Protocol Security (IPSec). L2TP/IPSec provides the user with the most advanced encryption technology, AES-256. L2TP is a popular protocol for its high level of security but it cannot bypass some restrictive firewalls as it used fixed ports to connect.

3] SSTP

Secure Socket Tunneling Protocol (SSTP) is also developed by Microsoft and used with Windows Vista SP1 and later versions. It has the ability to transport data through Secure Sockets Layer (SSL). Hence, the name Secure Socket Tunneling Protocol. SSL secures the data that passes through it with different ports which can bypass most of the firewalls. SSTP is natively supported on Windows and not available on any other platforms. Even the protocol is not audited publicly for the possibility of any backdoor entries.

 4] OpenVPN

OpenVPN is the open-source VPN tunneling protocol that encrypts the data that passes through it with AES-256 like L2TP. The difference between the two is the code that is available openly for audits and anyone can find the vulnerabilities and fix them. That is the reason, it is considered the most secure VPN tunneling protocol. Also, it is supported on different platforms and most of the VPN service providers use this for the same reason. OpenVPN provides faster connections and can bypass almost every firewall.

5] WireGuard

This is the new and latest VPN tunneling protocol which aims to be fast, secure, lightweight, and easy to use. It is a security-focused protocol that uses proven cryptography protocols and algorithms to secure the data. WireGuard is not available on some of the VPN service providers though it is better in speed and security than OpenVPN as it is the latest technology and the VPN service providers are in the process of incorporating it into their programs.

These are the various types of VPN tunneling protocols that we use in a VPN.
