VLANs – CompTIA Security+ SY0-401: 1.3
Nearly every network requires the administration of virtual LANs, or VLANs. In this video, you’ll learn about VLANs and how they can be used to logically segment and secure your network.
Subnetting the Network – CompTIA Security+ SY0-401: 1.3
One of the key concepts of TCP/IP networks is subnetting. In this video, you’ll learn why we subnet our networks and you’ll see a network design that incorporates separate IP subnets.

DMZ – CompTIA Security+ SY0-401: 1.3
A common network design is to include a virtual DMZ (demilitarized zone) to separate the Internet from the inside of the network. In this video, you’ll learn how a DMZ is used as a layer of protection and which devices you would commonly find in a DMZ.

Log Analysis – CompTIA Security+ SY0-401: 1.2
The event and access logs from network devices can provide a wealth of information. In this video, you’ll learn how post-event analysis and real-time analysis of logs can provide valuable security information.
Network Separation – CompTIA Security+ SY0-401: 1.2
One of the fundamental best practices of network security is to segment the network to prevent access and protect resources. In this video, you’ll learn about network separation and how organizations can use different segmentation strategies in their infrastructure.

Spanning Tree Protocol and Loop Protection – CompTIA Security+ SY0-401: 1.2
Spanning Tree Protocol (STP) is an important standard that provides a mechanism for switched networks to avoid outages due to network loops. In this video, you’ll learn how loops can cause network issues and I’ll demonstrate what happens when Spanning Tree constantly adjusts to avoid network loops.

Flood Guards – CompTIA Security+ SY0-401: 1.2
A relatively easy way to overwhelm network devices is to attack them with a flood of network packets. In this video, you’ll learn about some of the more popular methods of flooding a network and how to help prevent these denial of service attacks.
