The data centre is evolving. This is a depiction of a customer’s typical virtualization journey from physical to cloud via virtualization.In stage 1, orgs have begun virtualization all of their low hanging fruit – web servers, file and print servers, some app servers, and begun to realize the hardware consolidation and operational management benefits that result in lower CAPX and OPEX costs.In stage 2, they have begun virtualizing more of their tier 1 apps and mission critical servers now. They are also leveraging some of the more advanced capabilities of virtualization such as automatic live migration, disaster recovery and software fault tolerance. Many stage 2 orgs have also started deploying virtual desktops as well.Benefits in stage 2 are even more cost efficiencies plus also higher QoS from the higher level virtualization capabilities.
Next we’ll cover instant-on gaps. [click]Unlike a physical machine, when a virtual machine is offline, it is still available to any application that can access the virtual machine storage over the network, and is therefore susceptible to malware infection. However, dormant or offline VMs do not have the ability to run an antimalware scan agent. [click]Also when dormant VMs are reactivated, they may have out-of-date security. [click]One of the benefits of virtualization is the ease at which VMs can be cloned. However, if a VM with out-of-date security is cloned the new VM will have out-of-date security as well. New VMs must have a configured security agent and updated pattern files to be effectively protected. [click]Again the solution is a dedicated security virtual appliance that can ensure that guest VMs on the same host have up-to-date security if accessed or reactivated, and can make sure that newly provisioned VMs also have current security. This security virtual appliance should include layered protection that integrates multiple technologies such as antivirus, integrity monitoring, intrusion detection and prevention, virtual patching, and more. .
I’d now like to highlight a couple of additional virtualization challenges. The next one we’ll discuss today is inter-VM attacks and blind spots. [click]When a threat penetrates a virtual machine, the threat can then spread to other virtual machines on the same host. Traditional security such as hardware-based firewalls might protect the host, but not the guest virtual machines. And cross-VM communication might not leave the host to be routed through other forms of security, creating a blind spot. [click]For the solution, protection must be applied on an individual virtual machine level, not host level, to ensure security. And integration with the virtualization platform, such as VMware, provide the ability to communicate with the guest virtual machines. Also, virtual patching ensures that VMs stay secure until patches can be deployed.
Patching is one of the most significant pain points for every IT department, and it also needs to be addressed in virtual datacenters. Patch cycles, virtual machine proliferation could soon make it very difficult to maintain compliant environments. http://www.vmware.com/virtualization/advantages/virtualization-management/patching.html VMware vCenter Update Manager lets you:Reduce the risks associated with patching hosts by allowing fast rollbacks to a pre-patch stage Eliminate application downtime related to VMware ESX host patching Increase IT administrator productivity with unique automation capabilities Increase flexibility by allowing delayed reboot of virtual machines VMware vCenter Update Manager is a fully integrated module of VMware vCenter Server. It does not require a complex installation or additional infrastructure.
In stage 3, organizations have started leveraging private and public clouds. The IT dept has transformed itself into acting as a service provider with charge-back type processes where consumers of IT are in effect renting computing space and time from IT. Benefits are further cost efficiencies, QoS and faster business agility.As orgs considered their move to stage 3, security was top of mind – IDC survey data shows that it is the #1 issue why orgs will not move to the cloud.

This can be integrated with your existing SIEM for further insight.Protect sensitive data, particularly when using cloud service providers with Encryption.<click>And just like our other solutions, it is powered by our Smart Protection Network, protecting against real-world threats faster.Our Cloud and Data Center Solution protects you on your journey to the cloud – now and in the future.
Let’s look at the example here:Let’s imagine a VMware ESX host with 15 virtual servers running on it, each of which has a locally installed security agent providing e.g. AM, Web Threat Protection, FW, DPI, IM. So what’s the problem with this approach? Simultaneous scanning, updates, network traffic analysis and so on lead to increased resource usage on each VM, and a cumulative resource impact on the ESX host which can be disastrous and lead to outages of the host and – therefore – all of the VMs running on that host. This is turn can result in a combination of the following:Less VMs per ESX hostReduced security on each VMNo security on each VMSo how does Deep Security solve this problem? Deep Security’s agentless protection abilities mean you can drastically increase the amount of VMs per ESX host – all without reducing the security posture of the VM. Which means one thing for VMware customers – increased ROI (and security!) in their virtual infrastructure.Savings on improved VM density:VDI: 50% more VDIsVirtual servers: 20 – 30% more virtual serversSavings during initial deployment:Where Deep Security saves significant setup time is when customers need to install multiple separate point security solutions – for example, for separate solutions such as anti-virus, host firewall, host IPS, and integrity monitoring. By providing these technologies in a single integrated virtual appliance, Deep Security reduces overall setup time relative to other market alternatives that deploy multiple agent-based solutions.Savings in on going management:Faster deployment on new VMsVirtual patching
Datacenter extension into the cloud – Workloads like Web or mail. Challenges with visibility and policy with the workloads and extension of networkDS – Allowing visibility into physical, virtual, cloud assetsBeing able to assign and enforce security policies across these workloads.
Each of these platforms has unique security concerns. With physical machines, the manageability of various security solutions can be an issue.There can be a glut of security products—either through excessive layering or overly specialized products. This increases hardware and software costs. Also, management across the different products can be difficult – causing security gaps. And collectively these issues create a higher Total Cost of Ownership.The solution is to reduce complexity by consolidating security vendors and correlating protection.[click]With virtualization, the risks pertain to both performance and threats specific to virtual environments. There is a concern that security will reduce performance, which reduces the ROI of a virtual infrastructure. Also there are unique virtual machine attacks, such as inter-VM threats. Here the solution is increased efficiency—security that optimizes performance while also defending against traditional as well as virtualization-specific threats. [click]With cloud services, the risks pertain to less visibility and cloud-specific threats. Companies are concerned about having less visibility into their applications and data. And they are concerned about increased external threats, especially in multi-tenant environments.For the cloud, businesses need security that allows them to use the cloud to deliver IT agility. Data must be able to safely migrate from on-premise data centers to private clouds to public clouds so organizations can make the best use of resources. [click]As we’ll see later, all of these concerns can be addressed. And through protection that is provided in an integrated security solution all managed through one console. With cross-platform security, you’ll stay protected as your data center and virtual or cloud deployments evolve, allowing you to leverage the benefits of each platform while defending against the threats unique to each environment.
