Description

The course begins by defining network infrastructure and network security. It then continues by describing the features and functions of the VPN protocol and the Point-to-Point Tunneling Protocol (PPTP). It will teach you how PPTP captures Point-To-Point (PPP) frames into IP datagrams for transmission over an IP-based network. You will also learn about L2TP and how it relies on IPSec in Transport Mode for encryption services. You will also look into how Firewalls protect a network from malicious attack and unwanted intrusion.

You will then learn how a Perimeter network keeps certain information open only to specific users or to the public while keeping the rest of the data an organization's secret. The course will also discuss how Application-level gateway functions, supports, and checks whether the type of application traffic is allowed. Finally, you will look into how the Network Intrusion Detection System(NIDS) detects and monitors network traffic and how the Network Intrusion Prevention System(NIPS) inspects, removes, and redirects malicious traffic.

With the proliferation of information technology, more and more of our personal data is being encoded and stored in the world wide web. This makes it a lot easier for hackers to gain access. While it is true that there is still no network that is totally immune to attacks, it is still essential to have trained professionals who can create stable and efficient network security system. By taking this course in Digital Network Security, you will take one big step towards becoming such a valued professional.
