Network security is a broad term that encompasses the protection, integrity and continuity of network-based assets, which include hardware, software and data, along with related network services. Here at Libra IT, our intention is to diligently keep our clients infrastructures safe and secure from maliciousness while informing our clients of possible threats with a recommended plan of action for the future. In previous posts, I wrote about the need for a new networking and security architecture, and its role in the SDDC. The SDN and SDSec stack is built around policy-based automation, leveraging centralized management and control with distributed network and security functions, while abstracting and untethering the stack from the underlying physical hardware. During today’s VMworld keynote, Steve Herrod demoed how the vCloud Suite paves the way for new datacenter SDN and SDSec architecture.
If you’re in San Francisco this week, there are several deep dive sessions in the networking & security tracks you can attend to learn more about this topic.
I spoke about abstraction, pooling, service insertion, and automation as the key building blocks for the SDN and SDSec stack.
I look forward to meeting some of you at VMworld, and hearing your thoughts and ideas about networking and security! Get 60% Off USB Security!On the 27 of May USB Security will be available on our partner's website at extremely low price of $13.98. To allow access to certain removable storage devices, it is possible to assign passwords to them. Network administrators will appreciate centralized installation and management facilities of USB Security.
Free updates for one year and steep discounts for upgrades for future versions after the one-year period expires. All information will be encrypted before transmission to prevent possible interception by a third party. Key elements of network security include strong user policies, network-access controls, and intrusion-prevention systems, which fend off malicious attacks through the Internet or determine access to shared network software.
The sheer breadth and depth of VMware and partner solutions being showcased and launched as part of the software-defined datacenter (SDDC) is staggering, with a ton of activity happening around two key pillars of the SDDC – software-defined networking (SDN) and security.
As we spent time working through the product release, and integrating with several partners, we began to see certain patterns emerge in realizing the software-defined networking and security architecture.
The platform must be extensible to enable instant insertion of additional abstractions into the virtual plane e.g.

Just as VMs were the container for server virtualization, the Virtual Data Center (VDC) is the container for the SDDC.
It is being bundled into the vCloud Suite, making it easier for customers to seamlessly automate their networking & security needs as they build, operate and manage cloud infrastructure. All of these technologies are featured in sessions this week and demoed at the VMware booth. Pre-eminent “Virtual Network Engineer” Serge Maskalik helped out on stage – effectively compressing weeks of intricate network and firewall engineering into a matter of minutes leveraging the power of the new architecture.
More than forty of our networking and security ecosystem partners will now be able to integrate their offering into the new architecture.
Nicira’s leadership in software-defined networking, adding network virtualization to other hypervisors and cloud management systems like OpenStack, and early wins in cloud scale datacenters makes for an exciting coming together of two awesome teams. These will continue to be especially important as VMware continues to integrate additional partner offerings.
Also, programmability of such fabrics will unleash a whole new wave of network-aware applications and innovative deployments, and increase the opportunity rather than curtail it, much like we’ve seen with compute and storage.
We value our partners and the joint work we’re doing together to address customer pain points. VMware is serious about software-defined networking and security, and helping our customers enable automation of the data center, including interconnecting heterogeneous pools on compute and storage.
USB Security blocks unauthorized USB devices such as memory card readers and USB flash drives, removable storage and USB hard disks while allowing devices such as keyboards, mice and printers to be used normally. Offering centralized deployment and management, USB Security is indispensible for enforcing security policies on removable storage devices, helps control file transfers and prevents virus infections. USB Security makes it possible to white-list USB devices deemed safe such as printers, scanners, keyboards and mice, as well as any devices explicitly allowed by the system administrator.
If such a device is connected to a PC running USB Security, it can be used provided the correct password is entered. Now it is possible to encrypt folders, protect files and folders in Windows Safe Mode and automatically enable protection if the computer has been idle for a while.
The following picture is a fairly succinct view of the stack – it should come as no surprise that some of these patterns are similar to the corresponding compute and storage stacks.
VDC deployments are completely automated via vCloud Director, and handle policy-based deployment of compute and storage, delegating networking and security deployments to the vCloud Networking & Security sub-system.

This program and the vCloud Ecosystem Framework, allow our partners to further extend the SDDC – a big win for our partners and customers. Ideally these specialized functions are virtualized, distributed, scale out, multi-tenant and manageable by the respective element manager, for the most seamless integration into the stack. Many of our security and networking partners are at VMworld this week, showcasing their compelling solutions for the SDDC in breakout sessions, demos and more. I’d like to thank the VMware networking and security teams who have worked hard to showcase all of this at VMworld in the keynotes, breakout sessions and deep dives in the network and security track and the hands-on labs. Running unnoticed, USB Security logs all attempts to connect authorized and disallowed USB devices, allowing system administrators to perform comprehensive audits of USB security at any time.
Simply updating the policy on a central server from the convenient console affects all computers on the entire network immediately.
These abstractions are instantiated via virtual switches (vSwitch) and virtual firewalls (vShield) respectively and deployed in a scale out fashion on each host hypervisor. Logical networks leverage these port groups and can be instantiated across the data center (VXLAN). The network and security virtualization layer provides a logical context for the instant insertion of such services.
A centralized command and control mechanism (vShield Manager) takes inventory of all the abstractions & pools, and is responsible for managing and mapping these pools into the needs of higher level entities like tenants or apps, and aligning with higher level virtual containers. The network and security virtualization layer effectively untethers the VDC from the underlying physical network and firewall architecture, and provides a logical foundation to build the stack.
Notions of multi-tenancy, isolation, elasticity, and programmability via RESTful interfaces are also handled here.
I encourage you to attend to learn more about the tremendous work happening in the ecosystem.
VM-based security is available via vShield Endpoint and endpoint security partner offerings. Because of the scale out nature of deployment, these pools are elastic and data center wide, and available on demand to be allocated to tenants or app owners.
