What Is Network Tunneling & How Is It Used? [1]

Cloud networking is complex and governed by numerous technologies, methodologies, and protocols.. One of the most fundamental protocols in cloud networking is tunneling.
The transmission takes place using a public network; however, the data are intended for use only within a private network. Network tunnels provide a direct connection between a remote server and the local network, and the transmission of data is undetectable by the public network.
In order to move requests through the tunnel from the remote client to the local network, requests need to be encapsulated. Network tunnels work using encapsulated packets of private network data and protocol information within the public network transmission

Types of Virtual Private Network (VPN) and its Protocols [3]

Types of Virtual Private Network (VPN) and its Protocols. VPN stands for Virtual Private Network (VPN), that allows a user to connect to a private network over the Internet securely and privately
Virtual Private Network (VPN) is basically of 2 types:. Remote Access VPN permits a user to connect to a private network and access all its services and resources remotely
Remote Access VPN is useful for home users and business users both. An employee of a company, while he/she is out of station, uses a VPN to connect to his/her company’s private network and remotely access files and resources on the private network

Encryption Techniques for Smart Systems Data Security Offloaded to the Cloud [4]

The name cloud computing was inspired by the cloud symbol that is usually used to represent the Internet in flowcharts and diagrams. Cloud computing provides a platform for hosting anything that needs resources over the Internet
Cloud computing provides shared computing resources rather than having dedicated servers. Applications, storage, and other host services are accessed via a web portal
Cloud computing enables companies to consume shared resources as utilities rather than having to build and maintain computing infrastructures on their own. Different types of resources can be shared, such as a virtual machine (VM/container), storage, or an application

Transport Layer Security [5]

Transport Layer Security (TLS) is a cryptographic protocol designed to provide communications security over a computer network. The protocol is widely used in applications such as email, instant messaging, and voice over IP, but its use in securing HTTPS remains the most publicly visible.
It runs in the presentation layer and is itself composed of two layers: the TLS record and the TLS handshake protocols.. The closely related Datagram Transport Layer Security (DTLS) is a communications protocol that provides security to datagram-based applications
TLS is a proposed Internet Engineering Task Force (IETF) standard, first defined in 1999, and the current version is TLS 1.3, defined in August 2018. TLS builds on the now-deprecated SSL (Secure Sockets Layer) specifications (1994, 1995, 1996) developed by Netscape Communications for adding the HTTPS protocol to their Navigator web browser.

Configuring GRE Tunnel Interfaces [6]

Generic routing encapsulation (GRE) provides a private, secure path for transporting packets through an otherwise public network by encapsulating (or tunneling) the packets.. GRE encapsulates data packets and redirects them to a device that de-encapsulates them and routes them to their final destination
For example, GRE tunnels allow routing protocols such as RIP and OSPF to forward data packets from one router to another router across the Internet. In addition, GRE tunnels can encapsulate multicast data streams for transmission over the Internet.
(For a list of limitations, see Configuration Limitations.). As a tunnel source router, the router encapsulates a payload packet for transport through the tunnel to a destination network

Fragmentation Explained [7]

MTU and MSS are two important terms you should be familiar with when you jump into the networking world, and especially if you are working with GRE tunnels and IPSEC.. MTU is the largest packet or frame size, specified in octets (eight-bit bytes) that can be sent in a packet- or frame-based network
MTU is usually associated with the Ethernet protocol, where a 1500-byte packet is the largest allowed.. One of the most common problems related to MTU is that sometimes higher-level protocols may create packets larger than a particular link supports.
Each piece is small enough to pass over the link it is fragmented for, using the MTU parameter configured for that interface.. The fragmentation process takes place at the IP layer (OSI layer 3), which marks packets as fragmented

What is IPsec (Internet Protocol Security)? [8]

IPsec (Internet Protocol Security) is a suite of protocols and algorithms for securing data transmitted over the internet or any public network. The Internet Engineering Task Force, or IETF, developed the IPsec protocols in the mid-1990s to provide security at the IP layer through authentication and encryption of IP network packets.
The former provides data integrity and anti-replay services, and the latter encrypts and authenticates data.. The IPsec suite also includes Internet Key Exchange (IKE), which is used to generate shared security keys to establish a security association (SA)
A special router or firewall that sits between two networks usually handles the SA negotiation process.. IPsec is used for protecting sensitive data, such as financial transactions, medical records and corporate communications, as it’s transmitted across the network
