Shellshock Security Scan and Remediation

Tuesday, September 30, 2014

If you've heard about Shellshock, you likely understand the significant vulnerabilities this bug exploits in Unix BASH shell, by allowing for arbitrary remote code execution and watering hole attacks, among other exposures. Some security experts claim it's potentially worse than Heartbleed, as it impacts vast amount of servers that process huge volumes of Internet traffic, including almost all CGI-based web servers. For example, by this past Friday afternoon (September 26, 2014), there had been over 17,000 attacks on more than 1,800 domains.

While reliable patches are still being developed, as the initial patch did not fully fix the problem, network and system administrators should scan their infrastructure for the existence of Shellshock, and perform remediation measures as soon as possible, which may include, preventing incoming traffic to servers impacted on the network.

Since this is a well-publicized issue, exploitation attempts of this vulnerability have been skyrocketing, making Shellshock security scans and remediation immediate priorities.

If you would like assistance with a Shellshock security scan, and/or Shellshock remediation services, particularly with your publicly exposed network segments, simply email us at to get started.

The Internet of Things Advances for IPv6 Enabled Devices

Wednesday, September 10, 2014

The Internet of Things (IoT) is another step closer to an everyday reality thanks to the development of an ant-sized, wireless radio by Stanford engineers (see video below), which could monitor and/or control IPv6 enabled devices. Additionally, Goldman Sachs' recent infographic below (scroll horizontally to view, or right click to save), and report helps illustrate the importance of Stanford's advancement, and the role IPv6 will have.

Outdoor Municipal WiFi Case Study

Saturday, August 09, 2014

City of Douglasville outdoor municipal WiFi
Last week, Aerohive released this case study on the municipal WiFi network we built for the City of Douglasville, GA. Below are a few of the highlights:

• deployment spans over 100 acres, across three separate locations
• includes both indoor and outdoor WiFi, as well as wireless backhaul
• actively used during sporting events, parades, and outdoor concerts
• IPv6 accounts for more than 20% of the traffic

If you're evaluating a WiFi deployment, please contact us, as we're always interested in learning about new wireless projects of all types and sizes.

ARIN Down to Final /8

Big announcement from ARIN today - only a /8 of available IPv4 addresses remain. Looks like we need to update the timelines in our infographic below.

Note, if you haven't begun IPv6 migration planning, we strongly recommend beginning soon, as "all IPv4 requests will be processed on a "First in, First out" basis, and all requests of any size will be subject to team review."

Tweets from the 2014 Texas IPv6 Task Force Summit

Saturday, March 29, 2014

If you missed the 2014 Texas IPv6 Task Force Summit this week in Dallas, below are a few Tweets from the conference. Note, it's only a sampling, and Twitter usage was low considering the outstanding list of speakers and presentations, but two key comments from Rich Jimmerson of ARIN were surprising, and should give network operators pause.
  • Largest IPv4/IPv6 dual stack deployment is in Germany - via @Latifv6
  • Dr. Anthony Rutkowski - the Internet is disappearing and moving toward NFV/SDN - via @Latifv6
  • ARIN has received requests for "very large" blocks of IPv4 space in the past couple of weeks - via @JimmRich (look for an announcement as early as this coming week)
  • Each organization needs an IPv6 plan - via @JimmRich
  • In the coming months to a year ARIN may turn down requests for IPv4 addresses; submit requests sooner than later - via @JimmRich (may begin as early as this coming week)
  • IPv6 privacy issues and concerns are also not trivial for the Internet of Things and legal frameworks will need to be constructed - via @vgcerf
  • IPv6 sensors provide potential for local municipalities to share information regionally and nationally - via @vgcerf
  • IPv6 will help cities become smart by becoming more aware through sensors, from government transportation to water use - via @vgcerf

Low IPv6 Traffic and Content Myth Debunked

Wednesday, March 26, 2014

If you're considering migrating your network to support IPv6, the graphs below may provide insight into the amount of v6 traffic your network could experience this year. As you can see, these charts reflect current, IPv6 and IPv4 traffic, as well as historical v4 and v6 traffic (approximately the last 9 months) for the City of Douglasville - a free, IPv6 enabled, municipal WiFi network we built last year.

Conclusion: the "waiting for IPv6 traffic and content" myth is debunked - non-trivial, production IPv6 traffic is here, and we expect it will continue to climb as ARIN's IPv4 free pool is exhausted around the end of this year - begin IPv6 migration planning today.

IPv6 Deployment Reality: begin network migration planning today

Thursday, March 13, 2014

Enterprise Technology
Excellent discussion with John Curran, President & CEO of ARIN, and Brandon Ross about IPv6, and why organizations should begin migration planning today - hosted by Robert Ballecer, and co-hosted by Brian Chee and Curtis Franklin. Note, our IPv6 landscape infographic will help illustrate the discussion.

Highlights include:
This week's show also explores IBM's data analytics strategy, as the company now has over 15K employees, including 400 mathematicians devoted to their Big Data portfolio of products.

The Interop Network: architecting, designing and deploying an evolving network every six months

Saturday, March 08, 2014

Building temporary wired and wireless networks for large trade shows like Interop is a significant challenge - making these networks interoperable between numerous hardware and software vendors, while supporting thousands of users with multiple devices passing large amounts of traffic is remarkable - and that is exactly what the InteropNet team does for each Interop, with limited time and resources. As Glenn Evans stated a few weeks ago, they build it new each time. This is due in part to new hardware, software and technical implementations the team seeks to demonstrate on the network.

To help illustrate the complexity of an Interop deployment, below is an overview of the network for Interop's Las Vegas show in a few weeks, which our CEO and Chief Network Architect, Brandon Ross helped design. Please feel free to post any questions or comments below, and he will respond.

Network Performance Gains with IPv6

Thursday, February 13, 2014

Interesting video from NANOG yesterday about IPv6 performance testing. Data analysis indicates that "v6 performance is generally faster than v4." (see some of the analysis from the video below)

5 Takeaways on the Present IPv6 Migration Landscape and IPv4 Exhaustion Timeline for 2014 (infographic)

Tuesday, February 11, 2014

Yesterday, we released the below infographic illustrating the present IPv6 migration landscape and challenges, with an IPv4 exhaustion timeline for 2014. While there are a number of takeaways, here are five:
  1. ARIN's IPv4 free pool has been depleting, on average, by approximately 35 million addresses each year since 2011, and as of December 2013, there were only 25 million IPv4 addresses remaining;
  2. Based on historical rates, IPv4 addresses from ARIN's free pool will likely be exhausted by the end of this year;
  3. The percent of IPv6 enabled networks worldwide is less than 20% (17.28%) - in the United States, it's less than 15% (12.90%);
  4. There are very few certified IPv6 network engineers (estimated to be less than 1,800 worldwide); and,
  5. The impending depletion of IPv4 addresses from ARIN's free pool, coupled with the low rate of IPv6 migration in the United States, will drive demand in 2014 for both IPv4 address acquisition, and IPv6 migration from a limited pool of resources. Start planning today.
