What you'll learn

From the very beginning to solid understanding what is Network Security

Understand most important Networking protocols: TCP, IP, IPsec and so on

Learn the fundumentals of Security concepts and how they are implemented in Networking

Understand network security devices: Firewalls, Routers, Switches

Begin your career in Network Security

Requirements

No requirements, only your Enthusiasm!

Description

I discovered you can break down Cyber Security training into just 2 core skills. (they are Networking & Security) and they are quite simple to start if you know the right method :) And even better, all subtopics build on top of each other.Which means if you work on them in the right order, you can shave years off of your learning curve.And that’s exactly what I show you how to do inside Network Security course.Also, instead of bogging you down with a bunch of boring and out-of-context lectures, I include a coherent step-by-step approach, which will lead you from the very beginning to the very essence of Networking and Security to get you start in that promising field.The following course includes lectures on how Networking Security works  and the walk-through from the very beginning to get you startedYou will have all necessary answers to these important questions:What is a Switch, a Router, a FirewallWhat is IP addressing? How to calculate it and use it and more!Lets talk about a Firewall, Antivirus, IPS and where are they in NetworkingWhat is a 0-day attack and how to protect against it? How to protect your computer and what's different about it? What is VPN? What types of VPNs exist and how to work with them.
