Micro segmentation is the particle of an effective network segregation
Network security administration barely leverages a concept which basically has been there forever and could literally saves them forever when dealing with security of network services, and that is nothing but micros segmentation.
I usually bring practical examples to my workshops so students are able to see and feel MS in real scenarios but as a brief explanation, micros segmentation is the technique of limiting a network node presence with only needed services and to the limited audience.
Get rid of the flat network but simple techniques around Micro Segmentation!
This simple technique is so away from majority of network configurations these days where nodes are all connected together to a switch and the most segmentation is done via virtual LAN segmentation. Micro segmentation takes care of nodes within their micro virtual world of services and clients.
MS turns most insecure network protocols to even more secure than a natively-secure-protocol, improve performance, and forever saves network from unknown attacks or malicious actors. Again, no specific tools is needed to implement this concept on a network of any kind, Linux, Windows, Mac… it fits with any infrastructure or technology, the only thing needed is the clear understanding of nodes, network services and their clients’ needs.
