Prevent lateral compromise with microsegmentation
It’s an unfortunate reality of information security: Eventually, everyone gets compromised. Manufacturers, banks, tech support companies, retail giants, power plants, municipal governments … these are just some of the sectors that have been affected by high-profile data breaches in recent months. Everyone gets hacked. You will, too.
This isn’t cause for despair. It simply means that effective security has to focus on more than just intrusion prevention. Hackers will eventually get into any network, if they’re willing to spend enough time and money doing so. But whether or not they get anything useful once they’ve gained entry—that’s another story.
Good network design can minimize the damage incurred during an attack. There are more ways to approach this than will fit in a single article, so this blog will only focus on network segmentation, and its smaller sibling, microsegmentation.
What is network segmentation?
Network segmentation is the practice of dividing a network into one or more subsections. Each subsection usually contains different kinds of resources and has different policies about who has access to that segment. There are a variety of ways to accomplish the division.
Network segmentation runs along a spectrum from the purely physical to the purely logical. The Continue reading

Upcoming Workshops: NSX, ACI, VXLAN, EVPN, DCI and More
I’m running two workshops in Zurich in the next 10 days:
- Comparing VMware NSX and Cisco ACI (and how EVPN and VXLAN fit into the big picture) on Thursday, November 28th;
- Explaining how you could use VXLAN with EVPN to build infrastructure for active-active data centers on Tuesday, December 3rd.
I published the slide deck for the NSX versus ACI workshop a few days ago (and you can already download it if you have a paid ipSpace.net subscription) and it’s full of new goodness like ACI vPod, multi-pod ACI, multi-site ACI, ACI-on-AWS, and multi-site NSX-V and NSX-T.
