What is Rootkit — Definition and Explanation. A variety of protocols use the public network, like the internet, to send private network data by creating a VPN Virtual Private Network , making its transmissions more secure, especially when using unencrypted data.

Because a datagram is used to hide packets of information, tunneling protocols become tools of immense benefits or misuse too. Poorly configured firewalls are easily overcome by enclosing the blocked protocols within an unblocked protocol to get past the firewall.

Deep packet inspection uses network infrastructure to look for the datagram, including suspicious behaviour and data, while egress and ingress filtering checks for the destination address. Thus tunneling protocols may pose a potential threat that needs to be blocked and addressed by IT and networking professionals who configure security protocols to be applied to data sent using a known tunnel through a VPN. Thus, to establish a connection, one needs to understand the tunneling protocol stack, networks, and both sets of protocols applied to delivery and payload.

Here both payload and delivery protocols are the same. Yet, the payload address is incompatible with the tunneling protocol of the delivery network. The L2TP Layer 2 Tunneling Protocol is used to transmit data between two nodes using the data-link layer and its frames to establish the connection. It can also struggle with bypassing restrictive firewalls because it uses fixed ports, making VPN connections with L2TP easier to block.

Secure Socket Tunneling Protocol, named for its ability to transport internet data through the Secure Sockets Layer or SSL, is supported natively on Windows, making it easy for Windows users to set up this particular protocol. Saving the best for last, we have OpenVPN , a relatively recent open source tunneling protocol that uses AES bit encryption to protect data packets.

Because the protocol is open source, the code is vetted thoroughly and regularly by the security community, who are constantly looking for potential security flaws. The protocol is configurable on Windows, Mac, Android, and iOS, although third-party software is required to set up the protocol, and the protocol can be hard to configure. After configuration, however, OpenVPN provides a strong and wide range of cryptographic algorithms that will allow users to keep their internet data secure and to even bypass firewalls at fast connection speeds.

SSTP, while very secure, is only available on Windows, and closed off from security checks for built-in backdoors. OpenVPN, with its open source code, strong encryption, and ability to bypass firewalls, is the best tunneling protocol to keep your internet data secure.
