segment all the things

The incomplete ITSA 2019 guide to segmentation

Next week it is the ITSA 2019 in Nuremberg and i thought it will be good to give you high priests of segmentation a overview of the companies exhibiting their solutions for segmentation and microsegmentation there. Illumio This one is special, because you will have the chance to meet me personally presenting the power of host-based microsegmentation to you for the three days of ITSA 2019. Feel free to come by and ask me anything about Illumio, this site or really anything that comes up.

Microservices and Microsegmentation

Cohabitation is a good thing

The thing to remember is that just because dev has decided to leverage microservices does not in turn mean that the network somehow magically becomes microsegmented or that if microsegmentation is used to optimize the network service architecture that suddenly apps become microservices. Microsegmentation can be used to logically isolate monolithic applications as easily as it can microservices. Article from DZone “Micro is big these days” - The below statement is from an article showing the similarities and differences between microservices and microsegmentation. Of course we all know the differences, but we might have never thought about the similarities between the two approaches.

Undivided We Fall: Decoupling Network Segmentation from Micro-Segmentation

@alissaknight has published a great article on LinkedIn that talks about the history of segmentation and the use-cases and differences of network segmentation and micro-segmentation. What i like about the article is that Alissa shows that network segmentation and micro-segmentation can be mutually exclusive, but can also co-exist. They do different things and they have different use-cases, which are also highlighted in the article. The conclusion though is what i wouldn’t agree to, a Software Defined Perimeter does not solve a lateral movement problem nor will it implement Micro-Segmentation. The underlying problem of having no visibility into what to segment and how to structure your policy so it does not break applications is not solved by moving to another solution.

Microservices and microsegmentation

Microsegmentation and microservices found this article on DZone and wanted to quickly share my thoughts on it. “Micro is big these days” - This statement is from a article showing the similarities and differences between microservices and microsegmentation. Of course we all know the differences, but we might have never thought about the similarities between the two approaches. Microservices are about dissecting applications to smaller units and run those units independently instead of running them in a monolithic application. This creates the ability to decouple those functions and makes the service more scalable, independent from the other services and easier to maintain a single functionality. Often one team is responsible for one microservice. They maintain their interface, but consumers of the service do not have to worry about the inner workings as long as they stick to the public interface.
