I started noticing several interesting trends in our customers about six months ago, and it really hit home when I spoke at the NAB show on IPTV testing a couple of weeks back.

With the large increase in converged application and service deployments (VoIP, IPTV, IMS, VPLS data services, etc.), I am on the road talking with Mu’s operator, government and vendor supplier customers on a consistent and frequent basis.

Is this latest bump in the economy a resurgence or just another corner? How can you learn to plan for the unexpected and unknown? Broad topic but very applicable to the growing number of leading network operators and their vendors using Mu to more completely test their networked applications and product development processes (software development life cycle, or SDLC).

Patrick wrote an excellent blog posting (http://www.nwwsubscribe.com/community/node/38818) about the way that Protocol Fuzzing could be used to find bugs like the recently disclosed "INVITE of Death." Patrick's blog made me wonder whether he's aware of the multiple commercially available fuzzing solutions that are on the market; of course, Mu has been shipping such a capability for almost 4 years now as part of a comprehensive automated reliability, availability and security testing solution.

The top-25 list certainly stimulated some discussion, but to my mind it placed too much of the blame for bugs on the programmer and didn't have enough appreciation of the role of complexity of networked software systems. The right way to tackle this problem is through thorough testing, using invalid or unexpected traffic based on what the software will be exposed to in the real world

When faced with complex systems with complex behaviors, software engineering tools and processes deployed throughout the software development life cycle must embrace, not ignore, the complexity in order to eliminate most bugs before the code is deployed in the field. Any tool that only looks at the code (source or binary) without testing the reactions of the code to real (broken) traffic, isn't even scratching the surface.

Is it really as simple as this: "There appears to be broad agreement on the programming errors," SANS Director Mason Brown said. "Now it is time to fix them. First, we need to make sure every programmer knows how to write code that is free of the Top 25 errors, and then we need to make sure every programming team has processes in place to find, fix or avoid these problems and has the tools needed to verify their code is as free of these errors as automated tools can verify." ?

Mu's had quite a few customer and prospect demonstrations around newer Service Level Traffic variation and related Mu Test Suite automation capabilities during the last month. From 20-31 October, the every 2 year MSF GMI event; from 19-22 October there was MPLS 2008; and on Nov 6, a customer case-study seminar for leading operators and vendors. This week offers IMS-based IPTV demonstrations at TelcoTV in Anaheim.

The recent Iron Chef event at Black Hat was a +1 for fuzzing where it was more effective than static code analysis (SCA) according to Dark Reading. It's also very interesting to me (and others) that both approaches found different bugs, but fuzzing found the important one (obviously) to do with interaction of the application with the rest of the environment.

Recently one of my European colleagues fielded a pretty important customer question about our Denial of Service module’s relevancy to the telecom industry. These customers have been using Service Level Traffic Variations pretty successfully for a year or so stateside to find potential points of failure and get them fixed. So what makes the Mu’s Denial of Service module particularly useful to service providers?

NXT 2008 had heavy interest in several NGN topics including:
# Ensuring real-time VoIP quality for all portions of an operator’s network
# Building reliable and available IPTV deployments by eliminating product weaknesses
# Figuring out what IP applications would attract the most business – and operator subscribers
# Preventing downtime for next-generation network applications like IPTV and VoIP, including deployments based on the IMS Architecture

A bigger part of the interest comes from the collision of norms happening right now within these organizations. The collision is between those who grew up in the Telco business and those who grew up in the world of IP, and at the heart of the conflict is the issue of reliability, availability, and security of end user services. This is also precisely where Mu Dynamics adds its value.

Downtime costs money, and organized testing is one of the only formal ways to manage or reduce downtime. Mu showed it's newest VoIP robustness and service assurance tools in 3 very public locations last week: cisco's Toolapalooza, Software Test & Performance and SIPit-22. This blog posting focuses on SIPit-22.

At the recent SANS SCADA in New Orleans, Eric Byres, Byres Security CTO and Kevin Staggs, engineering fellow and global security architect, Honeywell Process Solutions discussed and demonstrated for the first time how undisclosed serial-based critical infrastructure products, including those with IP-based network architectures, are quite exposed to more safety issues and ultimately, failures, in ways never before possible.

During a 9 month study recently Mu Security released, Network Strategy Partners principal Peter Fetterolf interviewed a number of leading service providers and their network product suppliers to learn more about the Total Cost of Ownership (TCO) benefits of using negative testing metrics during both product deployment and development. Fetterolf’s findings quantify both service provider and network supplier dollars (often $10,000 or more per incident) saved by minimizing downtime and maximizing service availability. NSP Partner whitepaper and Internet Telephony’s Webcast also include 4 service provider, cable operator and vendor supplier case studies.

This first Mu Line blog topic focuses on how both service providers and their suppliers are integrating automated negative testing throughout their respective deployment and development lifecycles to reduce downtime due to product weaknesses and vulnerabilities – many of which are unique to their customers differing network use cases.

Welcome to Mu’s first web log (The Mu Line blog) post of 2008. Many of Mu’s service provider, critical infrastructure and network product vendor customers have been asking for more regular industry updates on both the business and technical benefits of negative testing and fuzzing use cases. We’re responding with the new Mu Line blog that will include first-hand posts from Mu’s customer front line worldwide, Mu’s global network of external test labs, our CTO and other industry observations.
