Virtual Private Network (VPN) basically VPN Service can be described as a communication technology that allows connections to and from public networks and uses the network like a local network. By using this public network, users can access features in their local network, get the same rights and settings as if we were physically in a place where the local network is located. One thing to remember is that a private network must be in a state of priority and confidentiality maintained. Data security and closed data transfers from illegal access and network scalability are the main standards in the Virtual Private Network. VPN services are supported by several data communication protocols, each of which has a different security concept. Let's get to know the concept and types of VPN service.
In this VPN Service, packets built in certain VPN protocol formats are encapsulated in many basic protocols or other operators, then sent between the VPN client and server, and finally encapsulated at the recipient side. For Internet-based VPNs, packages in one of several VPN protocols encapsulated in an Internet Protocol (IP) package. The VPN protocol also supports authentication and encryption to keep the tunnel secure. Here are some types of VPN that you often encounter.
PPTP is the most popular protocol and is supported by many devices, the easiest to install, and the least overhead to use. The disadvantage of using PPTP is that it uses a weak encryption key (128 bit) so it should not be used with sensitive data transfers.
L2TP is a tunnelling protocol that combines two tunnelling protocols namely Cisco's L2F (Layer 2 Forwarding) and Microsoft's PPTP. L2TP is used to create a Virtual Private Dial Network (VPDN) that can work with all types of communication protocols. Generally, L2TP uses port 1702 with the UDP protocol to send L2TP encapsulated PPP frames as tunnelled data.
IPSec is a tunnelling protocol that works at layer 3. IPSec provides security services on IPlayers by allowing the system to choose the required security protocol, estimating what algorithms will be used on the service, and placing the cryptographic key needed to provide the requested service. IPSec provides these security services by using a security method called Internet Key Exchange (IKE).
IKE is built based on the Oakley protocol and ISAKMP. IKE has to handle negotiating protocols and security algorithms that are created based on the policies implemented. And in the end, IKE will produce an encryption system and security key that will be used for authentication used on this IPSec system.
This Multi-Protocol Label Switching or MPLS VPN is used best for connection types from Site to Site. This is since MPLS is the most flexible and adaptable option. MPLS is a standard-based source that is used to accelerate the distribution of network packets through many protocols.
SSL stands for Secure Sockets Layer and TLS stands for Transport Layer of Security. Both of these function as a protocol that is used to establish VPN connections. This VPN connection is where the web browser serves as a client and user access is limited to certain applications rather than the entire network. The SSL and TLS protocols are particularly utilized by online shopping websites and service providers. SSL and TSL VPN give you security sessions from your PC to the application server.
PPTP is the Best VPN that has been around for more than a decade. This VPN Service protocol has many advantages ranging from security to speed. However, there are some weaknesses related to the use of PPTP. The following advantages and disadvantages of using PPTP.
If you want to use a protocol that is easy to set up and allows high-speed performance, but you don't want to commit to maintaining a truly secure browsing experience, then PPTP is a VPN protocol that you should use for your home or business needs.
L2TP / IPsec in VPN Service combines all the best features of PPTP and L2F. Below is a complete analysis of the advantages and disadvantages of the protocol.
Because this protocol has double the transmission of data protection, this will affect speed. Which is slower when compared to the PPTP protocol. This protocol is commonly used on VPN Android.
In addition to avoiding geographical censorship, restricting access to search history to ISPs and governments, securing data, VPN Service provides other benefits to satisfy users. Like for example on the VPN App.
Note that VPN is not a flawless system. There are several limitations so that every user can use this kind of computer system wisely and economically.
Lots of business people now use VPN service to support their business. This is because the internet offers convenience in promoting and conducting business transactions. So what are you waiting for? Immediately come try VPN services!
