Open source software is changing the world of Information Technology. But making it work for your company is far more complicated than simply installing a copy of Linux. If you are serious about using open source to cut costs, accelerate development, and reduce vendor lock-in, you must institutionalize skills and create new ways of working. You must understand how open source is different from commercial software and what responsibilities and risks it brings. Open Source for the Enterprise is a sober guide to putting open source to work in the modern IT department. Open source software is software whose code is freely available to anyone who wants to change and redistribute it. New commercial support services, smaller licensing fees, increased collaboration, and a friendlier platform to sell products and services are just a few of the reasons open source is so attractive to IT departments. Some of the open source projects that are in current, widespread use in businesses large and small include Linux, FreeBSD, Apache, MySQL, PostgreSQL, JBOSS, and Perl. These have been used to such great effect by Google, Amazon, Yahoo!, and major commercial and financial firms, that a wave of publicity has resulted in recent years, bordering on hype. Large vendors such as IBM, Novell, and Hewlett Packard have made open source a lynchpin of their offerings. Open source has entered a new area where it is being used as a marketing device, a collaborative software development methodology, and a business model. This book provides something far more valuable than either the cheerleading or the fear-mongering one hears about open source. The authors are Dan Woods, former CTO of TheStreet.com and a consultant and author of several books about IT, and Gautam Guliani, Director of Software Architecture at Kaplan Test Prep & Admissions. Each has used open source software for some 15 years at IT departments large and small. They have collected the wisdom of a host of experts from IT departments, open source communities, and software companies. Open Source for the Enterprise provides a top to bottom view not only of the technology, but of the skills required to manage it and the organizational issues that must be addressed. Here are the sorts of questions answered in the book: Why is there a "productization gap" in most open source projects? How can the maturity of open source be evaluated? How can the ROI of open source be calculated? What skills are needed to use open source? What sorts of open source projects are appropriate for IT departments at the beginner, intermediate, advanced, and expert levels? What questions need to be answered by an open source strategy? What policies for governance can be instituted to control the adoption of open source? What new commercial services can help manage the risks of open source? Do differences in open source licenses matter? How will using open source transform an IT department? Praise for Open Source for the Enterprise:"Open Source has become a strategic business issue; decisions on how andwhere to choose to use Open Source now have a major impact on theoverall direction of IT abilities to support the business both withcapabilities and by controlling costs.

So you're thinking of creating an open source community around your code? Here are some things you ought to know before you make your plans too firm. Community Types: There is no single "open source community." Rather, there are many groups of people gathered around many free software commons. Those gatherings are themselves of several different types; you really need to understand those differences. Payment at the Point of Value: Open source is of course free software. But the freedom you're finding brings you value varies depending on the role you play with respect to the software. "Free" doesn't mean the same to everyone. Open Core Is Bad For You: The "open core" business model is popular with VC-funded startup companies but does not deliver the core freedoms from which lasting business value for customers is derived. Transparency and Privacy: The key success factor in an open source community is the equality of all the participants. A strong community is characterized by high levels of transparency about the project coupled with strong respect for the privacy of the participants. Read why you should not impose your business model on anyone.

Many small and medium scale businesses cannot afford to procure expensive cybersecurity tools. In many cases, even after procurement, lack of a workforce with knowledge of the standard architecture of enterprise security, tools are often used ineffectively. The Editors have developed multiple projects which can help in developing cybersecurity solution architectures and the use of the right tools from the opensource software domain. This book has 8 chapters describing these projects in detail with recipes on how to use opensource tooling to obtain standard cyber defense and the ability to do self-penetration testing and vulnerability assessment. This book also demonstrates work related to malware analysis using machine learning and implementation of honeypots, network Intrusion Detection Systems in a security operation center environment. It is essential reading for cybersecurity professionals and advanced students.

Open Source has become a buzzword synonymous with growth and change in computing. This book examines the Open Source movement, what's worked and why, and explains the technology to the mainstream investor and manager looking to replicate the successes of the Open Source movement.
