Professor Wool - Introduction to Microsegmentation

[@Asalhotra]

Thank you very much, Professor. Your video is very precise and to the point. It provides the context in a very easy-to-learn language, and ways to approach the implementation of Micro-segmentation in your environment.

This is a great explanation. As a network engineer I've seen many admins and CTO's struggle with getting a handle on the same flows and data requirements you mentioned. It's a great discovery process and exciting to me as an engineer... CTO's....not so much :)

@@avishaiwool5457 what's the best way to connect with you? LinkedIn or email? I would love to share the slide deck I prepared taking a cue from your lecture too. I teach the MBA IT Business Management students who opt for Information Security Management as a specialization.

Thanks for the video. But I still don't understand what the difference is between microsegmentation and regular segmentation using VLANs and subnets.

[@stianmaurstad]

I didn't make this presentation. But I can try to explain: VLAN segmentation are for larger subnet or VLANS containing groups of host with similar functionality. Like Printers, IOT, Dev, PCI, etc... MicroSegmentation, is doing the same, but at a lower level, this is around each physical or virtual L3 Switch port (at least that is how I see it), basically doing this control on a host port basis, so that each node can't reach or be a risk for the other hosts on the same VLAN/subnet. There seldom any reason why they should be allowed to reach each other. Most often they need to be reached from other Client / server VLAN's. The "devil is in the details" of creating this policy. Doing this correctly makes it harder for adversaries to move latterly in your org.

[@Asalhotra]

@@stianmaurstad thank you for this explain. I gather VLAN, subnet approach doesn't extend to the hybrid environment in the modern-day application architecture and underlying infrastructure. You really need controls at Layer 7 and above.
- Infrastructure
- Containerized Workloads
- Identity etc.
