Computer Networking - Digital Network Security

The digital security training course begins by defining network infrastructure and information security in web services. 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. In this digital security training, 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.

In this cyber security certifications, 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 digital security 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.
