The Different Types of VPN
December 15, 2023
The VPN or Virtual Private Network protects the data by means of encryption before sending it to the destination. Data packets Interceptor on the public network can not read, while someone who takes the right data packet on an unencrypted connection could get the user ID and password. You can use forms of encryption as well as what the VPN connection provides.
What are the Different Types of VPN?
There are several VPN services offering different VPN connection methods. A method uses an IP or IPsec security protocol. VPN using IPsec uses layer 3 of the OSI model to encrypt data, or with a header authentication or tunneling security load. IP security can encrypt data transport or in the tunnel, and IPSec VPN supports public key cryptography.
A second solution uses an L2TP Tunneling Protocol Layer-2. An L2TP uses a Point-to-Point Tunnel Protocol by Microsoft in collaboration with Cisco Layer-2 Forwarding.
Secure Socket Layer or SSL VPN is a third method of creating a virtual private network. SSL is a data encryption protocol. SSL encrypts data exchanged between client and server and websites. SSL relies on certificates that verify a computer or identity server before creating the connection. This is called an SSL handshake. The exchange certificate is transparent to the user.
The Benefits of SSL VPN
There are many benefits of using SSL VPN than other forms of VPN. SSL VPN is easier to implement IPsec. SSL VPN can be combined with other forms of identification, such as a token issued to users and pass-codes. SSL VPN works with the proxy. However, SSL VPN is not intended for site connectivity. IPsec is a better choice in this case.
However, SSL VPN services have a number of advantages over IPsec. Certificates of certification authorities are cheaper IPsec networking. However, security protocols are now essentially eliminated more acceptances of self-signed certificates.
