US defense contractor stored intelligence data on Amazon server without a password

About 28GB of sensitive US intelligence data was discovered on a publicly-accessible Amazon Web Services’ S3 storage bucket. The cache, containing over 60,000 files, was linked to defense and intelligence contractor Booz Allen Hamilton, which was working on a project for the US National Geospatial-Intelligence Agency (NGA). NGA provides satellite and drone surveillance imagery for the Department of Defense and the US intelligence community.The unsecured data was discovered by Chris Vickery, who now works as a cyber risk analyst for the security firm UpGuard.According to UpGuard, the “information that would ordinarily require a Top Secret-level security clearance from the DoD was accessible to anyone looking in the right place; no hacking was required to gain credentials needed for potentially accessing materials of a high classification level.”To read this article in full or to leave a comment, please click here

Capacity Planner Version 2.0 Released

Modern Wi-Fi networks are complex beasts. Despite all the fancy new features in products, the technology is only becoming more complex and the demands on the network are only growing. Wi-Fi is the most heavily used method to transport user data today, eclipsing cellular and LAN traffic volumes according to multiple reports from analysis firms including Cisco, Ofcom, Mobidia, Ovum, and others. Meanwhile, the technical complexity contained within the IEEE 802.11 standard results in a technical document that is over 3,200 pages long!  This means deploying a network right is no easy task.

One of the most difficult aspects to get right when deploying a Wi-Fi network is understanding capacity requirements. It is not sufficient enough to use rule-of-thumb guidelines based on number of clients per access point or number of access points per square foot/meter since they often result in networks that do not adequately meet actual end-user demands and perform poorly. More rigor is required while maintaining simplicity of use so that most network administrators can be confident of a successful outcome.

Essential to wireless network performance and capacity planning is understanding the interaction between access point capabilities, network configuration, client device capabilities, and the RF Continue reading

Tempered Networks makes it HIP to connect the unconnectable

IP networks were originally designed to be fairly simple. There’s a source and a destination address, and the network devices use this information to perform some fancy calculations—and magically, things connect. But as the internet has grown and more endpoints have been connected, networking has become a black magic. Since it’s impossible to give every device its own unique IP address, the clever folks at networking companies came up with an assortment of workarounds, such as being able to NAT (network address translation) non-routable, private addresses. And as we’ve added more dynamic environments, such as private and public cloud, defining policy based on addresses or ranges has become unsustainable. To read this article in full or to leave a comment, please click here

Transforming the Internet Society’s web presence

Have you struggled to find information on our current website? Have you found it difficult to know what actions you can take on important issues such as connecting the unconnected and building trust on the Internet?

You are not alone.

In one of the most visible and important changes we are making this year, we are working hard on giving our website a deep refresh.  We are building it to be a direct vehicle for action. We are redesigning it from the ground up to help us achieve our objective of connecting everyone, everywhere to a globally connected, trusted Internet. 

It will look different, it will feel different, it will be more accessible and will be more aligned with this strategic goal.

Multi-site Active-Active Solutions with NSX-V and F5 BIG-IP DNS

I’ve written several prior blogs on multi-site solutions with NSX-V discussing topics such as fundamentals, design options, multi-site security, and disaster recovery; see below links to review some of the prior material. In this post, I’ll discuss how VMware NSX-V and F5 BIG-IP DNS (prior known as F5 GTM) can be used together for Active/Active solutions where an application is spanning multiple sites and site-local ingress/egress for the application is desired. F5 offers both virtual and physical appliances; in this post I demonstrate using only the virtual (VE) F5 appliances. Big thanks to my friend Kent Munson at F5 Networks for helping with the F5 deployment in my lab and for providing some of the details to help with this blog post. This is the first of several blog posts to come on this topic.  Continue reading

Cumulus Linux and Ansible — now easier than ever

Back in November, Cumulus Networks unveiled NCLU, an interactive command-line interface for configuring switches running Cumulus Linux. NCLU was made to help networking experts drive Linux without having to learn its intricacies and quirks, and so far, it has been very successful. Network engineers are comfortable configuring devices interactively, so NCLU helps abstract the file-based nature of Linux to smooth out the learning curve.

Since I started working at Cumulus Networks over two years ago, I’ve noticed that most of our customers who are working with us for the first time fall neatly into two categories. The majority of our users are experienced network engineers with very little Linux knowledge, whereas a minority are Linux server power-users who may only know the basics of networking. Most of my colleagues at Cumulus are networking industry veterans who started off in the first category, while I fell into the latter. I’ve always been an automation-first developer who applies web-scale principles to everything I do, meaning that from the first day I started configuring Cumulus Linux, I was doing so with tools like Ansible. With the release of Ansible 2.3, I’m happy to report that Ansible now supports NCLU out of Continue reading
