Using sdn to secure the campus - Networkshop44
This document discusses how Hewlett Packard Enterprise uses software-defined networking (SDN) to secure campus networks. SDN provides programmable networks that can rapidly align with business applications. HPE delivers the functions of an SDN architecture, including separating the control and data planes and providing open programmable interfaces. This allows for network service automation through virtual application networks and security applications like Network Protector, which provides malware protection and intrusion prevention. The document provides examples of customers using HPE's SDN solutions and the benefits of risk-free SDN deployment.

Editor's Notes
- #5 Bullets: Our vision for SDN is to create a programmable network that delivers business applications quickly To offer agility for the network As well as alignment for the network It has to include consistent architecture across the enterprise: DC, campus and branch It must be built on open standards that enable an open ecosystem, so that everybody can participate – partners, customers and developers And that open ecosystem will reignite innovation for the networking industry (new apps) And those innovations need to be easily accessible to customers in a new marketplace that enables new business models
- #9 Virtual application networks deliver automation and agility. We are the first in the market to have a complete portfolio for each layer of SDN architecture.
- #10 Phase 1: SDN Ready Deploy: SDN-enabled networks Benefits : - Investment protection - Open Standards - Low risk Phase 2: Hybrid SDN (now) Deploy: Hybrid Mode SDN Networks Benefits: - Application aware network - Reduced complexity - Non disruptive Phase 3: Native SDN Deploy: End-to-end SDN Networks Benefits: - Fully programmable - Highly automated - Rapid innovation

- #21 With NSX, virtual networks are programmatically created, provisioned and managed, utilizing the underlying physical network as a simple packet forwarding backplane. Network and security services in software are distributed to hypervisors and “attached” to individual VMs in accordance with networking and security policies defined for each connected application. When a VM is moved to another host, its networking and security services move with it. And when new VMs are created to scale an application, the necessary policies are dynamically applied to those VMs as well.
- #22 It’s important to understand the challenge micro-segmentation solves, because it’s one that has been know but not solvable in reality until now. If we look at all the well publicized attacks over the last couple of years, Target, Home Depot, Sony and more they all were different from a hacker code perspective, but they all had one thing in common…once the threat got through the perimeter defense, whether through the firewall or from the inside…there was little of no lateral controls to keep the threat from moving from server to server until it found what it was looking for and started pumping out credit card numbers or other private information Nirvana to most security teams is “micro-segmentation” or a “zero-trust” approach. However, even if your company can afford the capital expense for enough firewalls to deliver the throughput capacity required to achieve high availability micro-segmentation for East-West traffic in your data center, the operational complexity of managing changes, VM movement, policy granularity, unsustainable policy table changes across all of these firewalls quickly becomes operationally infeasible.
- #23 It’s easy to understand why traditional approaches are operationally infeasible… When packets leave the VM they must traverse the network to be evaluated and enforced at a chokepoint firewall. That means that when the VM was provisioned, someone had to write the rules and put them into the firewall, a time consuming, error prone process that slows down application provisioning...then, if the VM ever moves, the firewall likely needs to be manually updated and if the VM is deleted, the firewall should be manually updated to remove the rules for the deleted VM. All combine to make this operationally infeasible at scale.
- #24 So how does an SDDC approach make it feasible? We automate everything, when a VM is provisioned, it’s security policies are provisioned with it, so that when the packet leaves the VM, it is evaluated and enforced, right at the virtual interface Then is the VM ever moves, the rules move with it, and if the VM is ever delete, the rules are deleted with it…no human interaction, it’s all automated.
