Computer Networking - Digital Network Security is a course that will introduce you to the network architecture and protocols used in network security.
The course begins by describing the features and functions of VPN protocol: Point-to-Point Tunneling Protocol (PPTP). You will learn how Point-to-Point Tunneling Protocol (PPTP) encapsulates Point-to-Point (PPP) frames into IP datagrams for transmission over an IP-based network. You will learn about L2TP and how it relies on IPSec in Transport Mode for encryption services.
You will then learn about Firewalls which are the most commonly used type of security device in an organization's perimeter and how they protect a network from malicious attack and unwanted intrusion. You will learn about the role of a Perimeter network that keep certain information open to specific users or to the public while keeping the rest of an organization's data secret.
You will learn about the two types of Packet filtering (Stateless and Stateful) and their functions. Next you will learn about Application-level gateway functions and how it supports address and port translation and checks whether the type of application traffic is allowed.
Finally, you will learn about the Network Intrusion Detection System (NIDS) which detects malicious network activities by monitoring network traffic, and the Network Intrusion Prevention System (NIPS) which inspects network traffic and can remove, detain or redirect malicious traffic.
This course will be of interest to all learners who would like to learn more about computer networking, the network architecture and protocols used in network security. It will also be of great interest to all learners who are considering computer networking as a career or who are considering doing professional computer networking exams.
