Understanding Cybersecurity: Network Segmentation

In this video Travis discusses why network segmentation is used as well as some common practices for segmenting networks. He uses the example of a small to medium office environment where it would be good security practice to segment IOT devices. He presents the concept of VLANs as well as routing between segmented networks and why network segmentation makes this more difficult.

One of the very most underrated channels here! Oh my God thank you very very much

[MrUnisteez]

Thanks! This was a simple explanation that gave me just enough information to answer a lot of the questions I had about network segmentation using VLANs.

In Mr. Burns voice....EXXCEELLENT... Great video. I'm a suscriber & sharing 👍

This is great video! would you mind clarifying the use of VRF in a segmented network?

You are super cute ! The Humor makes it enjoyable to watch ❤

Appreciate this for for an office environment but just for anyone (like myself) looking for ways to segregate a home network, having a L2 Switch (VLAN capable) is not enough for looking to implement VLAN in this way - you need a router that supports VLAN's and nearly all consumer-level routers don't support this.

Thinking of 2 10gbe switches with Asus 89x router which has 2 10gbe ports. Not sure both can be used at the same time.

What gear do you use to draw? (hardware and software) Wacom?

[SifuNuhai]

How do you test the VLAN is working accordingly?

Can I still do with if I want to segregate my wireless security cameras? - am I going to need 2 wireless routers then?

The security concepts such as L2 segmentation, FW, ACL, router on a stick etc. are all fine. However, my impression is that you try to cover too much in this vlog and give the wrong impression to an especially novice user that these basic security techniques are the holly grails that will cure all security concerns.
Therefore I would rather start with a top-down analysis, highlight potential attack vectors and demonstrate which technique would be suitable to mitigate what concern. I.e. what you mention few times in your vlog as defense-in-depth
