Fortinet FortiGate-VMX and NSX use cases

NSX is an extensible platform; other vendors security solutions can be added to it by means of the Northbound REST API, and two private APIs: NETX for network introspection, and EPSEC for guest introspection.

Fortinet’s FortiGate-VMX solution uses the NSX NETX API to provide advanced layer 4-7 services via service insertion, also called service chaining.  This enables the additional inspection of VM traffic prior to that traffic reaching the vSwitch.  This enhances micro-segmentation where there is need for greater application recognition, anti-malware, and other Next Generation Firewall features.  The scale-out nature of NSX is maintained as NSX handles the instantiation of FortiGate service VMs on the hosts within the deployed cluster retaining its operational advantages, if the cluster grows additional FortiGate-VMX service machines will be created as needed.

 

 

One of the primary advantages to FortiGate-VMX is the availability of VDOMs for multi-tenancy in a service provider or enterprise environment – this enables segmenting traffic by organization, business group, or other construct in addition to application.  The segregation includes the administration, VDOMs are managed independently of one another, this can also be used to split the different security functions such as anti-virus, IPS, and application control into isolated units or only Continue reading

VMware AppDefense & CB Defense Demo

As you may have heard, VMware and Carbon Black have come together to deliver best-in-class security architected for today’s data centers.

In this demo, you’ll see an example of how CB Defense and VMware AppDefense combine to enforce known good application behavior and detect threats using industry leading detection and response technology.

For this demo, we’ll show how an advanced security breach can come in under the guise of an innocuous application (Powershell) and often go undetected.  We’ll walk through the steps that security teams can now take to respond and address the attack all in one application.

BrandPost: Deciphering the SD-WAN buzz and predictions

We were excited to participate in the November MEF 17 conference in Orlando, one of the industry’s most informative service provider events of the year. There is a lot of buzz and interest in managed SD-WAN services. It was a key focus area of MEF’s new SD-WAN initiatives and for this year’s conference agenda.Silver Peak Founder and CEO David Hughes delivered a CEO perspective: “SD-WAN From Software-Defined to Self-Driving.” David presented a vision for how SD-WAN technologies that leverage AI and automation can further accelerate the development of managed, customized SD-WAN services. David’s presentation also explored the future of SD-WAN and its impact on the broader software defined networking space.To read this article in full, please click here

SDN with Big Data Analytics for an Intelligent Network

Software, cloud computing and IOT are rapidly transforming networks in a way, and at a rate, never seen before. With software-as-a-service (SaaS) models, enterprises are moving more and more of their critical applications and data to public and hybrid clouds. Enterprise traffic, that never left the corporate network, is now shifting to the Internet, reaching out to different data centers across the globe. Streaming Video (Netflix, Youtube, Hulu, Amazon) accounts for an absurdly high percentage of traffic in the Internet and content providers have built out vast content distribution networks (CDNs) that overlay the Internet backbone. Higher resolutions (HD and UHD) will increase the traffic further, and by some accounts, will be over 80% of the total network traffic by 2020. More and more businesses are being created that reach their customers exclusively over the Internet (Spotify, Amazon, Safari, Zomato, etc). Real-time voice and video communications are moving to cloud-based delivery and network operators are challenged to deliver these services without impacting user quality of experience. And if this was’nt enough, with the advances being made in IOT, we have more devices than ever, lively communicating and chatting in real time over the Internet.

Security becomes a prime concern as Continue reading

Worth Reading: The Smart Home Battle Front

The fragility of “smart homes” was brought to the forefront this week as a letter made the rounds allegedly sent by an ISP to its customers noting that those accused of repeated online copyright infringement activity could have their internet access suspended. Such a letter is hardly remarkable in today’s copyright aware environment, but what made this one stand out is the ISP’s notice that suspension of a user’s internet connection “may affect other services which you may have connected to your internet service, such as the ability to control your thermostat remotely or video monitoring services.” Does this really mean our ISP has the ability to cut off our heat in the middle of the winter? —Kalev Leetaru @ Forbes

IDG Contributor Network: Is it time for a network tax cut?

It is truly remarkable to what extent corporate and personal behavior is dictated by tax policy. Much of the discussion in our nation’s capital in regard to tax reform has been about competitiveness as a rational to lower corporate tax rates. It appears as though the United States charges a 20 percent higher tax rate than much of the rest of the world, forcing corporations to shift some operations and assets into lower tax rate jurisdictions. It’s safe to say that tax policy impacts behavior in measurable ways.Just yesterday I was speaking with a communications service provider analyst. We discussed the overhead of SD-WAN tunnels. I showed the math of how it can tax various protocols. The tax for various protocols was:To read this article in full, please click here

IDG Contributor Network: 3 ways networking will change for the better in 2018

As I discussed in "Why web-scale is the future," over the past year, we’ve seen more organizations embrace it as the “go-to” model for flexible, resilient and on-demand infrastructure. Gartner predicts that by 2020, 40% of global enterprise CIOs will have initiated a corporate web-scale IT initiative.As web-scale principles continue their rise within large enterprises, the role the network plays for the business, as well as the day-to-day working lives of network engineers, will change in some pretty significant ways in the year ahead.1. Networks will help fuel digital transformation rather than slow it down 40 percent of CEOs rank digital transformation as their top imperative, according to a recent Economist Intelligence Unit survey. More than ever, digital transformation is crucial to business success; in 2018, spending on the software, hardware and services that enable digital transformation will reach nearly $1.3 trillion, predicts analyst firm IDC. This figure “represents a 16.8 percent jump compared to the $1.1 trillion spent this year” (Datamation).To read this article in full, please click here
