Federal Computer Week published a great, succinct quote from Richard Schaeffer Jr., the NSA’s (National Security Agency) information assurance director, on three approaches that are effective in protecting systems from security attacks:
We believe that if one institutes best practices, proper configurations
[and] good network monitoring that a system ought to be able to
withstand about 80 percent of the commonly known attack mechanisms
against systems today, Schaeffer said in his testimony. You can
actually harden your network environment to raise the bar such that
the adversary has to resort to much, much more sophisticated means,
thereby raising the risk of detection.”
Taking Schaeffer’s three tactics as our lead, here is a FOSS perspective on these protection mechanisms:
Best practices implies community effort: discussing, sharing and collectively building understanding and techniques for managing systems and their software components. FOSS (Free and Open Source Software) communities develop, discuss and share these best practices in their project support and development forums. Debian’s package management system implements some of these best practices in the operating system itself thereby allowing users who do not participate in the development and support communities to realize the benefits of best practices without understanding or even knowing that they exist. This is one of the important benefits of policy- and package-based operating systems like Debian and Ubuntu.
Proper configuration is the tactical implementation of best practices. Audit is a critical element here. Debian packages can use their postinst scripts (which are run after a package is installed, upgraded, or re-installed) to audit and sometimes even automatically fix configuration problems. Right now, attentive, diligent systems administrators, i.e., human beings, are required to ensure proper configuration as no vendor — not even Debian — has managed to automate the validation let alone automatically fix bad configurations. I think this is an area where the FOSS community can lead by considering and adopting innovations for ensuring proper configuration of software.
Good network monitoring invokes the discipline of knowing what services are running and investigating when service interruptions occur. Monitoring can contribute to configuration auditing and can help focus one’s efforts on any best practices that should be considered. That is, monitoring helps by engaging critical thinking and building a tactile awareness of the network — what it does and what is exposed to the activities of a frequently malicious Internet. So, like proper configurations, monitoring requires diligent, attentive systems administrators to maintain security. LinuxForce’s Remote Responder℠ services builds best practices around three essential FOSS tools for good network monitoring: Nagios, Munin, and Logcheck.
DevOps is about increasing efficiency, but nothing is more inefficient than building the same application twice. However, this is a routine occurrence with enterprise applications that need both a rich desktop web interface and strong mobile support. With recent technological advances from Isomorphic Software and others, rich desktop and tuned mobile experiences can now be created with a single codebase – without compromising functionality, performance or usability. In his session at DevOps Summit, Charles Kendrick, CTO and Chief Architect at Isomorphic Software, demonstrated examples of com...

With all the incredible momentum behind the Internet of Things (IoT) industry, it is easy to forget that not a single CEO wakes up and wonders if “my IoT is broken.” What they wonder is if they are making the right decisions to do all they can to increase revenue, decrease costs, and improve customer experience – effectively the same challenges they have always had in growing their business. The exciting thing about the IoT industry is now these decisions can be better, faster, and smarter. Now all corporate assets – people, objects, and spaces – can share information about themselves and thei...

The cloud. Like a comic book superhero, there seems to be no problem it can’t fix or cost it can’t slash. Yet making the transition is not always easy and production environments are still largely on premise. Taking some practical and sensible steps to reduce risk can also help provide a basis for a successful cloud transition. A plethora of surveys from the likes of IDG and Gartner show that more than 70 percent of enterprises have deployed at least one or more cloud application or workload. Yet a closer inspection at the data reveals less than half of these cloud projects involve production...

Microservices are a very exciting architectural approach that many organizations are looking to as a way to accelerate innovation. Microservices promise to allow teams to move away from monolithic "ball of mud" systems, but the reality is that, in the vast majority of organizations, different projects and technologies will continue to be developed at different speeds. How to handle the dependencies between these disparate systems with different iteration cycles? Consider the "canoncial problem" in this scenario: microservice A (releases daily) depends on a couple of additions to backend B (re...

Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
