This can impact an organization financially, as they have to buy licenses for these VPN clients.

Generally, IPSec requires installing IPSec 3rd party client Application/ Hardware in client PC, and the user has to start the application to start the secure connection.

What is the difference between IPSec VPN and SSL VPN? SSL communication uses two keys to encrypt data, a public key, which is shared to everyone, and a private key for the receiving party only. To enable SSL Tunnel VPN, the web browser must be capable to handle active contents. Especially this method supports a variety of application and protocols which may not be web-based. SSL Tunnel VPN: This method enables web browser to access multiple network services. Client can access the SSL VPN gateway using any standard web browser, and the client has to provide necessary credentials as required by the SSL VPN Gateway, to authenticate. SSL Portal VPN: This method provides secure access to multiple services using a single standard SSL connection to the relevant web site.

Sockets are used to transfer data between sender and receiver. SSL VPN (Secure Sockets Layer Virtual Private Networks) provides standard web browser based VPN solution in Transport Layer. This function is performed by the protocol known as Association and Key Management Protocol which uses digital certificates to authenticate receiver with the sender. Tunnel Mode: Encrypts both Payload and Header.įor a successful communication initialization, IPSec uses mutual authentication (2 Way) protocols to establish the communication and to keep the communication continue, it shares a public key between sending and receiving devices. Transport Mode: Only Encrypt Payload of IP Packet and no encryption for Header portion. IPsec basically supports two encryption methods, Transport mode and Tunnel mode: The security is implemented based on authentication and encryption of IP packets at Network layer. This protocol is commonly used to implement Virtual Private Networks (VPNs). IPSec (Internet Protocol Security) is a protocol designed to ensure the security of data sent through a network. So that, Network Security is a major aspect for any organization, Enterprise and institutions in order to protect assets and integrity. In such technologies, employees can access their company private network through public networks such as internet. Nowadays, office virtualization is a rapidly spreading technology, in which employees can work physically in different geographical regions.

Due to this, the security of transferred data is playing a major role in network communication. These communication links are not always in a single network, there can be multiple public and private networks. These public and private networks communicate with different types of networks belonging to different sectors such as businesses, government agencies, individuals etc. With the evolution of the networking technologies, networks were expanded in both private and public aspects.
