An Approach That Works

Comparing open and closed source security

Seemingly everyone has insight into the open source versus closed source security debate. Each side provides plausible arguments for the benefits of their own model and points out drawbacks of the other. The proponents of open source argue that the source code is open and available for anyone to see, for many sets of eyes to examine, and is therefore more secure. Opponents of open source say that this "many eyes" theory is irrelevant since the vast majority of users will never look at the source code. Countless arguments ensue from there and can get quite derived, much like arguments over the exact number of episodes of Star Trek.

Looking past these arguments, it's helpful to examine the theory of security as it is approached by open and closed source software organizations. To that end I'll look at the security approach of the Debian Linux project as compared to the security approach of Microsoft - I'll use Microsoft as an example acknowledging the important role that they play as a target of security-related attacks due to their market share in the desktop operating system environment.

Security for both Debian and Microsoft is chiefly accomplished through the use of software patches. Debian issues patches for Debian-specific software problems as well as non-Debian-specific problems. These patches run the gamut of any of the thousands of software packages available with Debian. Some of this software isn't even Linux specific but runs on other operating systems as well, including Microsoft Windows. Microsoft releases patches only for Microsoft-specific software.

With the thousands of software packages available with Debian, security bugs are impossible to avoid. Most updates are not specific to Debian but rather affect the software as it runs on Linux, Mac OS X, and Microsoft Windows alike. Regardless, the software updates become available to users of Debian Linux through the apt package utility. Even if the problem isn't directly related to operating system functionality, the update is easily downloaded and automatically installed. On the other hand, updates for Microsoft through the default "Automatic Update" service consist of what Microsoft terms to be core functions. These core functions include updates to bundled products such as Internet Explorer and Media Player but don't include updates to other Microsoft software such as Microsoft Office, Exchange, SQL Server, and others. Security flaws in this additional software can lead to full compromise of the computer and the data contained therein, as is the case with operating system flaws.

The timing of security updates best reveals the differences in how the two models approach security. One of the aspects of open source security is transparency - virtually as soon as a security flaw, theoretical or practical, is reported, it's released to the general public so that users of the software can take steps to mitigate the effects of the security flaw. A patch follows very shortly after for all of the popular open source software packages. If a patch isn't readily available within hours, the community frequently steps up to release an intermediate patch and to help others mitigate problems associated with the flaw.

On the other hand, Microsoft has undertaken the policy of releasing patches only monthly for the operating system functions. While this results in fewer security notices to the public, it does nothing to enhance security. In fact, releasing patches on a monthly cycle rather than as necessary increases the possibility of exploit. The only people who know about the exploit are the people responsible for finding it and Microsoft. Of course, the people who find software exploits are all honest individuals with no ill intentions, right? Imagine that a burglar found a new way to pick door locks and shared this information with their friends-in-crime, and the police found out about the impending crime spree. Now imagine the police did nothing to alert the public about this danger because they only talked to the public monthly. Transparency and openness of security flaws and defects in products should be demanded by customers for their own safety.

Comparing the security approaches of open and closed source software organizations illustrates the inherent structural differences between the two models. Open source organizations such as Debian believe in greater protection, openness, and transparency of the security process so that their users can protect themselves. Closed source organizations such as Microsoft believe that they know best how, where, and when to disseminate information about security flaws. Unfortunately for users, this means quietly, discreetly, and belatedly.

In addition to all the benefits, IoT is also bringing new kind of customer experience challenges - cars that unlock themselves, thermostats turning houses into saunas and baby video monitors broadcasting over the internet. This list can only increase because while IoT services should be intuitive and simple to use, the delivery ecosystem is a myriad of potential problems as IoT explodes complexity. So finding a performance issue is like finding the proverbial needle in the haystack.
The 19th International Cloud Expo has announced that its Call for Papers is open. Cloud Expo, to be held November 1-3, 2016, at the Santa Clara Convention Center in Santa Clara, CA, brings together Cloud Computing, Big Data, Internet of Things, DevOps, Digital Transformation, Microservices and WebRTC to one location. With cloud computing driving a higher percentage of enterprise IT budgets every year, it becomes increasingly important to plant your flag in this fast-expanding business opportuni...
Large scale deployments present unique planning challenges, system commissioning hurdles between IT and OT and demand careful system hand-off orchestration. In his session at @ThingsExpo, Jeff Smith, Senior Director and a founding member of Incenergy, will discuss some of the key tactics to ensure delivery success based on his experience of the last two years deploying Industrial IoT systems across four continents.
The Internet of Things will challenge the status quo of how IT and development organizations operate. Or will it? Certainly the fog layer of IoT requires special insights about data ontology, security and transactional integrity. But the developmental challenges are the same: People, Process and Platform. In his session at @ThingsExpo, Craig Sproule, CEO of Metavine, demonstrated how to move beyond today's coding paradigm and shared the must-have mindsets for removing complexity from the develo...

We all know the latest numbers: Gartner, Inc. forecasts that 6.4 billion connected things will be in use worldwide in 2016, up 30 percent from last year, and will reach 20.8 billion by 2020. We're rapidly approaching a data production of 40 zettabytes a day – more than we can every physically store, and exabytes and yottabytes are just around the corner. For many that’s a good sign, as data has been proven to equal money – IF it’s ingested, integrated, and analyzed fast enough. Without real-ti...

I wanted to gather all of my Internet of Things (IOT) blogs into a single blog (that I could later use with my University of San Francisco (USF) Big Data “MBA” course). However as I started to pull these blogs together, I realized that my IOT discussion lacked a vision; it lacked an end point towards which an organization could drive their IOT envisioning, proof of value, app dev, data engineering and data science efforts. And I think that the IOT end point is really quite simple…
A critical component of any IoT project is what to do with all the data being generated. This data needs to be captured, processed, structured, and stored in a way to facilitate different kinds of queries. Traditional data warehouse and analytical systems are mature technologies that can be used to handle certain kinds of queries, but they are not always well suited to many problems, particularly when there is a need for real-time insights.
Big Data, cloud, analytics, contextual information, wearable tech, sensors, mobility, and WebRTC: together, these advances have created a perfect storm of technologies that are disrupting and transforming classic communications models and ecosystems.
