The need to secure enterprise IT infrastructure and data is intuitive, but how we achieve that security must change; traditional security concepts need to evolve.
Where we once thought of the firewall as a barrier around the perimeter of the enterprise, that perimeter itself is getting harder to define in an age of Software-Defined Infrastructure, Hybrid Cloud, and increasingly ubiquitous wireless and mobile communication.
The applications we use and the data we protect now travels across infrastructure, and it’s becoming harder to control. The Cloud applications we use inevitably rely on compute resources often far from our direct influence. Even when we use a Private Cloud to directly control compute resources and storage, mobile-enabled users want to access that Cloud from anywhere at any time. This whitepaper explores this concept and presents how micro-segmentation allows you to take a group of virtual machines and segment them off from neighbouring virtual machines – even on the same network.
VMware NSX makes micro-segmentation possible, and when aligned to application components, the lateral spread of threats within the data centre can be drastically mitigated.
