Macro Vs Micro Network Segmentation

To segment organizational market a company can use macro segmentation variables like an organization s size its location and the industry it is a part of.

Macro vs micro network segmentation.

Vlans firewalls and acls network segmentation isn t new. A great example of this is the failure of network technology to allow a server to live in multiple dimensions. Network segmentation is best for north south traffic and microsegmentation adds a layer of protection for east west traffic server to server application to server web to server etc. The two levels of network segmentation.

Companies have relied on firewalls virtual local area networks vlan and access control lists acl for network. Network segmentation in computer networking is the act or practice of splitting a computer network into subnetworks each being a network segment advantages of such splitting are primarily for boosting performance and improving security.

No one can guarantee that micro segmentation would have prevented every recent breach but i can argue that the obstacles to deploying fine grained security in the data center go away with micro segmentation. So while macro segmenting isolates traffic between vns micro segmenting controls communications between different groups or members of the same group within the vn.

Using the age old and some security professionals might say tired analogy. Can a database serve two different applications that live on different network segments. The result is better network performance and a simpler architecture in complex virtualized and software defined data centers with fluctuating workloads.
