The telecommunication and network security domain deals with the security of voice and data communications through local area, wide area, and remote access networking. The focus is to understand the networking models such as Open Systems Interconnect (OSI) and TCP/IP models, which are the most important models that follow a layered approach to networking, as well as the security mechanisms for Internet, Intranet, and Extranet in terms of firewalls, routers, and intrusion detection and protection systems.
The telecommunication and network security domain is one of the 10 domains of the Certified Information Systems Security Professional (CISSP) exam.

In the mid 1990s, the rise of the Internet and the increase in speed of cheap Internet connections paved the way for new technologies. This lead to the idea of providing secure connections between enterprise branches through low-cost lines using the Internet. This is a very basic description of what VPNs are all about.
In this article by Markus Feilner, we will discuss the features and advantages of OpenVPN followed by its release history.Read Advantages and History of OpenVPN in full
