January 1, 2017 Comments Off on Spark for Dummies is now available
A few years ago, I wrote Hadoop for Dummies, which presented an executive-level overview of Hadoop, its capabilities, and its amazing potential. Since then, the Big Data world has continued its relentless march forward, with Apache Spark serving as one of the most exciting and well-adopted new technologies. I’m happy to announce that I’ve just written a companion book dedicated to Spark. Here are the major topics that I cover in this book:
- Spark’s history
- How it works
- Why it’s such an important Big Data breakthrough
- Real world use cases
- How Spark, MapReduce, and Hadoop can work together
- How you can deploy it in your enterprise
- Best practices

This book – which was sponsored by IBM – is a great example of the kinds of high quality technical marketing content developed at Think88. These include white papers, case studies, evaluation guides, technical presentations, and market research.
October 30, 2016 Comments Off on Why the recent Internet of Things (IoT) attack is just the beginning
A few days ago we witnessed a new type of distributed denial of service (DDoS) incident. Unlike previous botnet attacks that enlisted compromised computers, this one corralled assorted unprotected devices like Internet-ready webcams, DVRs, and baby monitors to flood Domain Name System (DNS) servers, and thereby seriously degrade the Internet for hours. I’ll leave the explanation of the mechanics of this incident to more qualified commentators, but I do want to weigh in on why I think these types of events are very hard to combat and why I’m very skeptical about the hype around the Internet of Things (IoT).
We all (well, many of us) know how important it is to keep our computers and software patched and up-to-date; most people also get why firewalls are essential. But consider these facts about IoT devices:
- They’re being created for just about every industry. This diversity means that it’s much harder for the entire universe of vendors to agree on common security standards: defining safeguards for a heart pump is a little different than for a Web-ready washing machine. I’ve served on my share of standards committees: to say that they move slowly is an understatement!
- They have really short development cycles. IoT is shaping up to be a brutally competitive landscape. The winners will be those vendors that deliver solutions to market quickly. Designing and building strong security safeguards takes time, and time is money. The end result is that device protection takes a back seat to market pressures.
- There’s limited space for security software. Margins are very thin on hardware devices: security-focused onboard storage space adds costs that aren’t directly related to functionality.
- They frequently rely on APIs for communication. I’ve blogged about API security in the past. Suffice it to say that it’s a rare API that’s locked down properly.
- New models are always coming on the market. Here’s the really scary part: even if vendors do start getting their security act together, it will be years before today’s highly insecure devices get retired. Meanwhile, they’ll be standing by for their next set of DDoS orders.
July 25, 2016 Comments Off on Announcing Swagger training & certification
Whether they’re employed internally, externally, or both, APIs are vital assets that connect systems, streamline workflows, and make every type of integration possible. In fact, beyond strengthening operational efficiency and enabling cross-system communication, APIs now serve as competitive differentiators for many organizations. It’s no exaggeration to point out that renowned technology-driven businesses such as Uber, AirBnB, or eBay live and die on the quality and performance of their APIs, and this intense reliance is spreading across every industry.
Swagger – and its ecosystem of standards and products – is in the process of transforming the ways that APIs are designed, developed, tested, and supported. I’m happy to announce that my colleague Chris Riley has created an outstanding one-day training and certification program to help enterprises get the most out of Swagger.
Chris is a world-class expert on DevOps, Continuous Integration, and everything else related to how modern APIs are being created, and this deep knowledge comes across in his courseware. He also happens to be a great trainer who is committed to helping his students gain the proficiency they need.

July 18, 2016 Comments Off on Presenting a Webinar on Delivering Data Security with Hadoop and the IoT
On August 9, I’ll be teaming with Reiner Kappenberger from Hewlett Packard Enterprise to explore some of the most pressing security implications of Hadoop and the Internet of Things (IoT). Hosted by the IT GRC Forum, here’s what we’ll be covering:
The Internet of Things (IoT) is here to stay, and Gartner predicts there will be over 26 billion connected devices by 2020. This is driving an explosion of data which offers tremendous opportunity for organizations to gain business value, and Hadoop has emerged as the key component to make sense of the data and realize the maximum value. On the flip side the surge of new devices has increased potential for hackers to wreak havoc, and Hadoop has been described as the biggest cybercrime bait ever created.
Data security is a fundamental enabler of the IoT, and if it is not prioritized the business opportunity will be undermined, so protecting company data is more urgent than ever before. The risks are huge and Hadoop comes with few safeguards, leaving it to organizations to add an enterprise security layer. Securing multiple points of vulnerability is a major challenge, although when armed with good information and a few best practices, enterprise security leaders can ensure attackers will glean nothing from their attempts to breach Hadoop. In this webinar we will discuss some steps to identify what needs protecting and apply the right techniques to protect it before you put Hadoop into production.

July 1, 2016 Comments Off on Helpful REST API 101 guide available online
For software developers and architects tasked with creating programmatic interfaces to their applications, there’s been a longstanding debate between utilizing the structure and standards of SOAP-based Web services versus offering the freedom and flexibility of REST APIs.
In the midst of all these deliberations, I’ve observed a great deal of confusion about what, exactly, defines a REST API. SmartBear has come up with a helpful resource that provides a nice overview of the origins, attributes, and goals of REST APIs. You can view the guide here.
If you’re interested in learning more about REST API design, development, and testing, check out my other postings on the subject.
March 30, 2016 Comments Off on Excellent article about FBI’s iPhone crack
Bruce Schneier has long been one of my favorite technology authors and bloggers. He manages to write about extremely complex topics in a very accessible way – a notably rare and highly admirable skill. His latest article explains why the secretive approach that the FBI is employing to unlock iPhones will eventually harm innocent users unless Apple is notified of the device’s vulnerability.
The problem with computer vulnerabilities is that they’re general. There’s no such thing as a vulnerability that affects only one device. If it affects one copy of an application, operating system or piece of hardware, then it affects all identical copies. A vulnerability in Windows 10, for example, affects all of us who use Windows 10. And it can be used by anyone who knows it, be they the FBI, a gang of cyber criminals, the intelligence agency of another country … anyone.
This is precisely why Apple needs to understand what’s happened. Otherwise, the next entity to break into iPhones may not be doing so in the legitimate and honorable interest of solving crime.
I read Bruce’s blog regularly, and recommend it to anyone interested in security and information protection.
