The Best VPN Service Based On Protocol

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.

Various VPN Protocols

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.

  1. Point-to-Point Transfer Protocol (PPTP)
  2. 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.

  3. Layer 2 Transfer Protocol (L2TP)
  4. 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.

  5. Internet Protocol Security (IPSec)
  6. 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).

  7. Internet Key Exchange (IKEv2)
  8. 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.

  9. Routing Protocol (MPLS / BGP)
  10. 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.

  11. SSL and TLS
  12. 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.

Advantages And Disadvantages Of PPTP

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.

Advantages
  1. PPTP supports all desktop and cellular operating systems. This is the most significant advantage of PPTP. If you are a Windows user, the Windows operating system automatically supports PPTP.
  2. PPTP is the easiest VPN protocol to set up even for those who have little experience in configuring VPN.
  3. Because of the low level of encryption, it means it's great for downloading, streaming and general use. This is the fastest VPN protocol that many people use. For example, unblocking geographically restricted content such as Hulu or Showtime.
  4. PPTP is cost-effective.
Deficiency
  1. Limited 128-bit encryption makes PPTP VPN protocol obsolete. This is an insecure protocol. Encrypted confidential information is not recommended for use with PPTP.
  2. Government agencies such as the NSA have been able to break the PPTP protocol.
  3. The stability of the connection can vary depending on the network, resulting in slower speeds.
  4. Can be easily blocked by the ISP because it operates exclusively on port 1723 and uses non-standard GRE packages that are easily identified.

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 Advantages And Disadvantages

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.

L2TP / IPsec advantages
  1. L2TP combines very different IPsec security protocols. IPsec uses 256-bit encryption for military class encryption has not been hacked by anyone.
  2. L2TP protects data changes from sender to recipient. Because L2TP uses double protection to secure data. The first protection establishes a point-to-point Protocol (PPP) connection between the sender and receiver, while the second protection contains IPsec which contains encryption for security. Of course, encryption makes it difficult for ignorant people to interfere.
  3. Setting up L2TP is very easy and also quite fast. Also, L2TP supports multithreading. Multithreading is the ability to allow the execution of several commands at the same time. That's quite beneficial because it improves protocol performance.
  4. Also, the L2TP / IPsec protocol works on a large number of platforms and operating systems such as iOS, Android and Linux. Making this protocol very flexible.
  5. L2TP / IPsec supports Perfect Forward Security (PFS). PFS is a key agreement protocol that guarantees that your session key remains intact without being hacked even though the server's private key has been hacked.
L2TP / IPsec shortages

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.

  1. The L2TP protocol communicates via User Datagram Protocol (UDP), this makes it easier for firewalls to block this protocol.
  2. Setting up this protocol takes a lot especially when you enter computer certificates. On a Microsoft 2008 server for example, before you can use L2TP, you must make changes to the registry. But this only happens if you don't use third - party software.

Advantages And Disadvantages Of OpenVPN

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.

Advantages
  1. Connect to Remote Networks
  2. Your ISP only sees fire
  3. Optimum security from Wi-Fi hotspots
  4. Download without restrictions
Deficiency

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.

  1. Problems with anonymity
  2. Slow navigation
  3. Limits for VPN used for mobile devices
  4. Insufficient Servers for Some VPN Providers

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!
