Welcome to your first and cool lecture!5:03
Lets talk about the terms we use in Network Security3:08

OSI model7:42
Physical Layer11:47
Explore how the physical layer converts data into bits over copper and fiber, compare straight-through and crossover Ethernet cables, and explain TX/RX pairs and auto detection.
DataLink Layer5:51
How do switches work?6:43
What is VLAN?9:04
Explore how switches learn MAC addresses dynamically or statically, and how VLANs create separate networks, using access and trunk ports to control broadcast traffic.
ARP3:50
Internet Layer and Routers7:20
IP addressing8:54
Subnet Mask11:33
Transport Layer0:58
Routes10:35
NAT14:00
Explore network address translation (nat) and its types, including many-to-one nat, static nat, and port forwarding, with practical examples of external and internal interfaces and port mapping.
Traffic flow in a network5:48
Demonstrate how traffic travels from Bob to Alice across two subnets, detailing IP addressing, MAC addresses, frames, and the transition from data link to transport layers.
Where is a Firewall in OSI?2:23
Explore where a firewall sits in the OSI model, between the data link (layer 2) and network (layer 3), operating on IP addresses and ports to block or allow traffic.

Next Generation FireWall (NGFW)9:52
Stateful inspection / TCP15:31
Examine how stateful inspection firewalls use a connection table to track TCP sessions, enabling one-rule setup and secure FTP traffic while blocking unexpected or out-of-state packets.
Firewall10:44
IPS attack and protection example4:17
Explore IPS attack and protection techniques within network security and cyber security. See practical examples from zero to advanced concepts.
Appliance's Front and Back panel3:23
Learn the front and back panels of a firewall appliance, including transceiver slots, patch ports, sync, management, console, USB, lights-out, and power for clustering and remote access.
Virtual Firewall or Physical Appliance3:21
Clustering12:42

What is VPN?9:08
VPN Terminology5:22
IPsec vs SSL4:00
Types of VPN8:42
VPN Routing12:34
IPsec4:03
SA - Security Association3:23
IPSEC: Phase 1 & Phase 213:05
IPsec: Main mode vs Aggressive mode - Part 110:03
IPsec: Main mode vs Aggressive mode - Part 24:16
DPD - Dead Peer Detection5:57
Detect and manage dead peers with dead period detection (DPD) by sending keepalive packets and awaiting ack to keep vpn tunnels alive, using on-demand, on-idle, or disabled modes across vendors.
PFS4:24
Explore perfect forward secrecy in ipsec, comparing enabling versus disabling pfs across phase one and two, using diffie-hellman and shared secrets.
IPsec: Tunnel mode vs Transport mode5:31
Compare ipsec tunnel mode and transport mode, explaining that tunnel mode encrypts the original IP header and data with ESP, prepends an outer IP header, and trades security for throughput.
Remote Access VPN: Traffic flow4:47
What is a 0-day attack and how to protect against it7:34
Learn how sandboxing pairs with a next-gen firewall to trap zero-day threats, using virtual machines to analyze suspicious files and block them based on behavior verdicts.
How about Endpoint Computers..7:34

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 started

You will have all necessary answers to these important questions:

What is a Switch, a Router, a Firewall

What is IP addressing? How to calculate it and use it and more!

Lets talk about a Firewall, Antivirus, IPS and where are they in Networking

What 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.
