November 10, 2016 Comments Off on Helpful article on journalist protection is relevant for us all
In the aftermath of this week’s US election, it’s worthwhile to – once again – revisit techniques to protect private information from those that have no business seeing it. Here’s a link to a very useful article from The Atlantic that might give you some ideas about how to safeguard your data. If you’re curious about other security and privacy topics that I’ve written about, here’s a shortcut to them.
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 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.

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.
October 16, 2015 Comments Off on Helpful, easy-to-follow instructions to assess and correct your browser’s SSL vulnerability
SSL has long been the primary method for encrypting the communications between your browser and the websites you visit. However, for years there have been reports about potential ways for unauthorized parties to exploit SSL weaknesses and thus gain access to your ostensibly secure interactions.
The latest news is that the Diffie-Hellman key exchange algorithm (using 1024-bit primes) has been compromised. This has serious implications for the privacy of your sensitive communications, including banking, shopping, and email, to name just a few.
Fortunately, there’s a very helpful online tool that will evaluate your risk. You can find it at https://www.howsmyssl.com/
You should run this tool for each browser that you use, and take action based on what it tells you. More about that later in this post.
Here’s what I learned when I ran it on my system:
Opera (I haven’t updated this for a while, so it’s no surprise that it’s vulnerable):
Safari (Based on these results, Safari is now a no-go until I get it corrected)
Firefox (I applied the fix from the article that I’ll describe below. The results are good)
Finally, here’s Chrome. Once again, I configured this browser using the information from the article below.
So what should you do if you get a ‘Bad’ message from the How’s My SSL tool? The Electronic Frontier Foundation (EFF) has published an excellent, easy-to-understand article with step-by-step instructions about how to tighten your browser security.
You’ll find it here.
April 28, 2015 Comments Off on Excellent article on laptop encryption
Did you know that you have very few privacy rights when you cross a border (into the US or anywhere else in the world, for that matter)? I blogged about the dangers of bringing a laptop through customs a while back. Naturally, it’s a good idea to remove any sensitive information from your laptop, especially when you’re traveling. For those situations that require you to keep important data on a computer that’s at risk of being inspected (or stolen), full-disk encryption can be a lifesaver.
Operating system vendors have been doing a great job at strengthening their products, so there’s really no excuse not to take advantage of encryption. Here’s a link to an excellent article from Micah Lee on The Intercept that explains how to do this on Windows, Mac, and Linux computers.
With step-by-step instructions, it’s one of the best written tutorials I’ve seen about this topic. It’s well worth your time to make the effort, but remember: don’t lose your password!
March 1, 2015 Comments Off on ServiceV – a superb service virtualization technology for the API and Agile era
I’ve been working with SoapUI since its earliest days, and I’m very excited about the direction that SmartBear is taking the Ready! API platform, which includes products such as SoapUI NG Pro, LoadUI NG Pro, Security, and ServiceV Pro.
At WiseClouds we deliver classes and supporting consulting services on all these exciting solutions, and we’re honored that SmartBear directly sells these courses to their clients. Many of our students go on to earn their SoapUI certification after attending these classes.
Mock services have long been one of the most useful features in SoapUI. Customers use mock services to quickly stand up virtual versions of the real services (SOAP and REST) that are in development. They can then construct their tests using these virtual services and then quickly switch over to the live services once they’re ready. Some of these enterprises have come up with really creative uses for mock services, including simulating middleware, third party APIs, telecom switches, and all sorts of other scenarios.
ServiceV represents a bold step forward for SmartBear, offering tremendous new functionality (such as assertions, datasources, and simulation for network latency and message buses – to name just a few) for creating virtual services, which are now known as Virts.
ServiceV is an idea whose time has come, for two primary reasons:
1. The rise of the API economy
It’s no secret that APIs are more essential than even before: it’s nearly impossible to go through your day without interacting with an API, whether or not you know it. They are the foundation of modern software, infrastructure, and the entire Internet. And APIs commonly invoke other APIs, which is an enormous increase in complexity.
This means that properly testing these assets is not an optional responsibility: it’s mandatory, and will continue to gain in importance. Failing to adequately test APIs can be disastrous – just read the news most days for the latest examples of outages, breakins, and other API failures.
ServiceV makes it easy to develop comprehensive tests that truly reflect the realities of the modern, API-based information-processing environment.
2. The advent of Agile delivery methodologies for software
Thanks to Agile techniques, software of all types – including APIs – is delivered much more frequently now. In many organizations, the quality assurance team is finding it nearly impossible to keep pace with the frenetic schedules driven by these practices.
ServiceV is a way for architects, developers, and operations staff to provide something for their quality assurance colleagues to use while the actual services are still being shaped and refined.
At WiseClouds, we’re so enthusiastic about what ServiceV represents that in addition to our current training and consulting solutions, we’ll be launching an exciting new Software as a Service offering that’s built upon ServiceV. If you’d like to learn more about that, be sure to subscribe to the blog and I’ll keep you posted.
