Healthcare CIO Perspective on BYOD, Security Vendor Selection

In bringing new security technologies into a healthcare organization, from a CIO’s standpoint, there has to be the right mix of compatibility and alignment with internal policy. And in deciding which technologies and vendors would work best for the organization’s project needs, the CIO has to take a high-level view of both staff and infrastructure needs. That alignment is often easier said than done, but for Jeffrey Brown, Lawrence General Hospital CIO, the key is balance and preparation for all IT projects.

Asterisk, Heartbleed, and You

Co-author of “Asterisk, Heartbleed, and You” – Olle E. Johansson, CEO Edvina AB, Sweden has more than 25 years of experience in the Unix and networking business, with ten years of VoIP experience. He is an Asterisk and Kamailio developer, trainer and consultant. The focus is on building large scale customized platforms for carriers, call centres and enterprises. Olle is also an advisor to many start-ups. After 25 years with IPv4 networking, he is also a strong advocate of IPv6 migration, being an active member and contributor to SIP Forum and IETF.


Recently, a vulnerability was discovered in the ubiquitous OpenSSL library. This bug, dubbed “Heartbleed”, allows unauthenticated attackers to discover and steal TLS/SSL protected information from vulnerable clients and servers. As the primary means of protecting information is typically performed using OpenSSL, the severity of this vulnerability cannot be underestimated.

Asterisk uses OpenSSL to encrypt signaling communication in many of its channel drivers, dialplan applications, and core functionality. This includes SIP and XMPP channel drivers, as well as the AMI and ARI interfaces. If you are using TLS with Asterisk and are using a vulnerable version of OpenSSL, you should upgrade your version of OpenSSL to a version containing the Heartbleed fix immediately. Versions of OpenSSL that are affected by the vulnerability include OpenSSL 1.0.1 through 1.0.1f, inclusive.

  1. Check if you have a vulnerable version of OpenSSL. Use the Linux/Unix command “openssl version”. If your version of OpenSSL is not a version previously mentioned, you are not exposed to this potential attack.
  2. Stop your asterisk process.
  3. Upgrade your OpenSSL libraries using the tools provided by your operating system.
  4. Generate new key material, a new CSR and get a new TLS certificate for Asterisk.
  5. Restart Asterisk with a new certificate.

If your Asterisk was using a vulnerable version of OpenSSL, consider changing credentials for accessing the system, like SIP secrets, AMI username and password, etc.

More information on the Heartbleed vulnerability can be found at http://heartbleed.com/.

We in the Asterisk community take the issue of security very seriously. We highly encourage all Asterisk administrators to verify their installations of Asterisk and upgrade their versions of OpenSSL, if necessary. If you have any concerns about security with Asterisk, please feel free to contact the Asterisk developers using the security@asterisk.org mailing address. For general discussions, please use the asterisk-users mailing list. We also encourage all third party distributions of Asterisk to spread this information and assist their userbase to protect their systems.

SDN and Wi-Fi: Will They Ever Be Friends?

Given that we’re in an age where most IP-based technologies converge on networks without borders, it stands to reason that SDN and WLAN — both white-hot topics in the industry today — should buddy up. But the story is a lot more complicated than that.

SDN initiatives are gathering steam on many fronts. Taking both the Grand Award and SDN category award in this year’s Best of Interop product competition,  the Open Daylight Project’s Hydrogen shows that even though software-defined networking is in its infancy, it’s also on many people’s minds as the obvious evolution of highly interoperable networking. And this is where we start feeling a bit of tension when contemplating how SDN and wireless networking might hook up.

Switchvox for Education: Google Hangout with Casper College

It’s no secret that educational institutions face challenging and unique problems everyday.  Some of the top challenges facing administrators of K-12 schools and universities include: campus safety; managing large numbers of students, faculty, and staff; overseeing large, spread out campuses; and fostering positive parent/teacher and student relations. Communications is certainly at the center of these challenges. So, it’s probably not a surprise that the most important tool to managing successful communications is a modern Unified Communications system, such as Switchvox. To help educators understand how to this type of tool can work on their campus, we recently launched a new program, “Switchvox for Education” which focus on how schools can save money, time, energy – while also minimizing frustration levels for the school’s administrator, faculty and IT staff.

As a key part of this program for schools, I had the great pleasure of hosting a Google Hangout with Kent Brooks, Director of IT for Wyoming-based, Casper College. During the live discussion, he detailed his deployment of Switchvox and the school’s experiences with the system thus far.  Kent is a wealth of information and regularly blogs about technology in schools on his website.  You can view Kent’s blog here.  The Hangout also included Vince Preece and Dustin Rollins from Seattle-based NP Information Systems, a Digium Select Partner and the reseller behind the Casper College project.  During the Hangout, Vince and Dustin chime in with their perspectives (as a trusted reseller) on the deployment and what challenges (and solutions) they encountered.   In case you missed the live discussion, you can view the recorded Hangout here!

If you are interested in learning more about Switchvox for Education, check out our Switchvox for Education Guide and visit our Switchvox for Education resource page.  There, you can also sign up for our webinar, “Is Your Phone System Old School” that focuses on how Switchvox benefits each major school role (administrator, IT staff, and teacher).  Also, plan on joining us for another education-focused Google Hangout on April 25, with Richard Sears and the American Heritage Charter School.

Meru Announces Commitment to Software-defined Networking (SDN) Using Open Standards

SUNNYVALE, Calif. – March 31, 2014 – Meru Networks® (NASDAQ:MERU), a leader in intelligent Wi-Fi networking, is implementing open standards-based SDN to enable application-specific service level agreements and unified management of wired and wireless networks. Meru’s approach to SDN goes a step further than offerings from other Wi-Fi vendors by providing both northbound and southbound APIs in its mobility controllers.

“Meru’s approach to augmenting the programmability and flexibility of wireless networks embraces the spirit and goals of the open networking community and the transition to SDN-enabled networks,” said Rohit Mehra, vice president, network infrastructure, IDC. “By fully supporting open, standards-based management and control all the way to the access point, Meru intends to provide support for SDN with an eye to meeting the needs of enterprise IT and network managers.”

Existing unified access management platforms are costly and closed, typically providing visibility and control of LAN switching as well as WLAN controllers and access points only when the entire solution is supplied by a single vendor. By taking the information exposed by application vendors’ SDN APIs and using it to their own advantage – optimizing performance of those applications without enabling management of both their controllers and access points – these vendors’ SDN implementations are incomplete.

Meru’s SDN-enabled Wi-Fi solutions will help ensure consistently high performance of critical business applications and simplify unified management of wired and wireless networks, giving customers immediate benefits without additional training or a “rip-and-replace” of their existing controllers and access points.

“SDN enables application performance, ease of management and simplicity of use for the unified wired and wireless access network,” said Ajay Malik, senior vice president of engineering and quality assurance at Meru. “Meru is working toward truly open, standards-based networks where best-in-class solutions win, removing complexity from access network deployment and management – without requiring additional training and equipment replacement.”

Meru Announces Two New 2×2 802.11ac Access Points – Including the World’s First Gigabit Wi-Fi Wall Plate

Wi-Fi leader’s expanded 802.11ac portfolio sets new industry benchmarks for deployment flexibility and price/performance

SUNNYVALE, Calif. – March 31, 2014 – Meru Networks® (NASDAQ:MERU), a leader in intelligent Wi-Fi solutions, today announced significant expansion of its 802.11ac portfolio with two new dual-radio, dual-stream (2X2) access points – the industry’s first 802.11ac wall plate access point, the AP122, and a new general purpose access point, the AP822. The new products extend the benefits of gigabit Wi-Fi to broader markets at lower price points and with higher performance than competitive offerings.

Both of the new access points support data rates of up to 867 Mbps as compared to competitors’3X3 solutions that are typically limited to 600 Mbps data rates. Meru’s higher data rates are enabled by the Meru MobileFLEX architecture, which supports full use of the 80MHz channel specified by the 802.11ac standard. Others recommend narrower 40 MHz channels in enterprise-wide deployments, which reduces their access points’ data rates.

“It’s now very clear that 802.11ac is the strategic direction for organizations of all sizes everywhere, but also that a variety of access points is required to address all market requirements,” said Craig Mathias, a principal with the wireless and mobile advisory firm Farpoint Group. “The Meru AP 122’s broad range of applications and the AP822’s performance and price add to the clear and compelling case for moving to 802.11ac instead of expanding legacy 802.11n networks.”

IDC forecasts that the number of network-connected devices will grow from 10 billion in 2013 to 212 billion in 20201. To support this explosion of devices, the new 802.11ac Wi-Fi standard combines multiple Wi-Fi channels to provide gigabit Wi-Fi data rates and support higher device densities. This reduces the number of available channels, posing little problem for the single-channel deployment option of the Meru MobileFLEX architecture, but hindering other vendors’ Wi-Fi access point deployment strategies. Other vendors assume a minimum of three overlapping channels to enable enterprise-wide Wi-Fi coverage.

The Meru AP122 Wall Plate – In-room Deployment for Hospitality and Higher Education
The AP122 is the first 802.11ac wall plate access point and is specifically designed to meet the ever-increasing mobile data needs of hotel guests, as well as resident college and university students.

With up to 1.2 gigabit-per-second data rates for only $595, the AP122 is perfectly suited to the in-room deployment needs of the hotel, cruise line and higher-education residence-hall markets. Designed to provide maximum coverage and capacity in multi-tenant environments, its inconspicuous design eases in-room cabling and placement and maximizes deployment flexibility.

The Meru AP822 – Gigabit Wi-Fi Power at Lower Cost
The AP822, with its optimal balance of low cost and high performance, is uniquely positioned to meet the growing need for 802.11ac WLAN in a wide variety of markets. Delivering up to 1.2 gigabit-per-second data rates for only $895, the 2X2 802.11ac AP822 is an obvious choice for schools, hospitals, hotels and other businesses seeking to give end users the high-performance of 802.11ac Wi-Fi at a lower cost than existing 3X3 solutions.

Meru 802.11ac solutions run on standard 802.3af Power of Ethernet (PoE). This greatly lowers total cost of ownership, eliminating the need for customers to upgrade their entire Ethernet switching infrastructure to support 802.3at, or PoE+, as currently required by most Meru competitors when deploying 802.11ac. Meru 802.11ac access points support devices on both the 5GHz and 2.4GHz bands and increase the performance of legacy clients, with Meru customers citing as much as 40 percent increased throughput when using 802.11n clients on its 802.11ac networks.

“The AP822 and AP122 extend Meru’s leadership in the 802.11ac market, giving us the broadest gigabit Wi-Fi portfolio to meet the widest range of customer needs,” said Manish Rai, vice president of marketing for Meru. “The performance advantages enabled by the MobileFLEX architecture give users unprecedented capacity and productivity improvement and make Meru a clear choice in education, healthcare, hospitality and general enterprise.”

The AP822 is available immediately. The AP122 will be available in the second half of 2014.
