Ransomware has been one of the more prevalent security topics for past few years. Some probably think this form of digital destruction is here for the long haul. While this may be an accurate prediction, I can imagine a turn of events that would end this form of attack. To be clear, my theory is not that enterprise networks will plug every possible entry point. My prediction is that the ransomware business model COULD cease to be viable.
Let me expand on my position. For a business model to work, it has to have a monetization strategy. For ransomware, that strategy includes the victim sending money (typically bitcoin) to the attacker—trusting that they will be given the keys to decrypt their files. In this model, the victim has to trust their attacker [to do the right thing]. In and of itself, that seems to be an oxymoron and a plea in desperation.
So if these types of attacks fail to produce recovery options and gain widespread coverage, this trust is further eroded. To some degree this has already happened with Nyetya.

4 Main, Key Design Principles of Mobile Networks – I will explain the 4 key design principles of cellular networks in plain English. In fact I should have said, cell based systems as mobile networks may not be design based on cell based architecture. Let me explain what would be the other deployment […]

Event driven or workflow driven automation for the uninitiated can appear daunting. With the rise of machine learning which adds more complexity to our field, simple rule driven automation feels more in reach than it ever has. This post aims to introduce you to a viewing lens for the world of great automation.
Converting processes in to workflows can be a tough task to accomplish and whilst this is relevant, it isn’t for this post. That’s one for another day but a great talking point and one that will be addressed.
Good automation tooling offers two views of the world; one high level that you pass arbitrary data around and one that handles interface implementation, which converts the arbitrary data to meaningful contextual data. In other words, a declarative and an imperative view, the ‘what’ and the ‘how’. The dimension that exists between the two can make or break the tool. If we have to care too much about how data is passed from one layer to the other, we’re not users, we’re more co-developers and it’s a kit not a tool.
Our Layer Cake model is simple at a high level. Two layers are enough to Continue reading

At VMworld Europe 2016, we showed that network virtualization is mainstream and that NSX will illuminate the path to bring your data center into the future with robust security, speed, and agility.
One year later, NSX is out to show that it’s not just in the data center anymore… it’s everywhere. Beyond helping you master the data center, NSX is setting out to empower you to reign supreme over the cloud, remote and branch offices (ROBO), and even containers. To help you get there, VMworld Europe 2017 has 70+ networking and security sessions and 60+ NSX customers to share expertise and direct experience with NSX. And on top of all of that, VMware will be presenting an exciting new security product to help ensure your applications stay secure!
Check out the list of the top, not-to-be-missed networking and security sessions below. You should also explore the schedule builder on VMworld.com to reserve your spot in the top networking and security sessions as well as to discover the whole range of introductory and deep dive NSX sessions covering the entire use case spectrum.
See you in sunny Barcelona at VMworld Europe 2017!

I got several questions along the lines of “why is Cisco pushing LISP instead of using EVPN in VXLAN-based Enterprise campus solutions?”
Honestly, I’m wondering that myself (and maybe I’ll get the answer in a few days @ NFD16). However, let’s start at the very beginning…

docker run -e "RTPROP=-Dviz.demo=yes" -p 8008:8008 sflow/vizceralIn this case, the detailed view shows messages flowing between microservices running in the Amazon public cloud. Similar visibility could be obtained by deploying Host sFlow agents with associated modules for web and application servers and modifying sflow/vizceral to present the application transaction flows. In private data centers, sFlow support in load balancers (F5, A10) provides visibility into interactions between application tiers. See Microservices for more information on Continue reading
Since March 30, 2017, Cloudflare has been providing DNS Anycast service as additional F-Root instances under contract with ISC (the F-Root operator).
F-Root is a single IPv4 address plus a single IPv6 address which both ISC and Cloudflare announce to the global Internet as a shared Anycast. This document reviews how F-Root has performed since that date in March 2017.
The DNS root servers are an important utility provided to all clients on the Internet for free - all F root instances including those hosted on the Cloudflare network are a free service provided by both ISC and Cloudflare for public benefit. Because every online request begins with a DNS lookup, and every DNS lookup requires the retrieval of information stored on the DNS root servers, the DNS root servers plays an invaluable role to the functioning of the internet.
At Cloudflare, we were excited to work with ISC to bring greater security, speed and new software diversity to the root server system. First, the root servers, because of their crucial role, are often the subject of large scale volumetric DDoS attacks, which Cloudflare specializes in mitigating (Cloudflare is currently mitigating two concurrently ongoing DDoS attacks as we write this).
