case study on open source software

A Business Case for Open Source – Why You Should Contribute to the Open Source Community

As an employed software developer today, there's a 96% chance that you're building company software using some sort of open-source technology.

You might be using VSCode, a free open-source text editor primarily maintained by Microsoft, or React, a free and open-source front-end JavaScript library, among many other tools.

Companies today love using free open source tools and technologies, but very few actually contribute back to the open-source community.

And I guess if you take out any emotions such as guilt or feeling indebted and boil it down to the bottom line – why should they? What is in it for them?

In this article, we'll look at what open-source is and why you or your company should consider making contributions.

How Does Open Source Work?

Open source refers to software where the code is shared publicly and that can be viewed, edited, or added to by anyone.

So for example, if you wanted to, you could view the code to see how VSCode is built right here . Then you could submit pull requests to suggest code changes or feature adds which would get reviewed by someone working on the codebase.

You could also create your own open-source project where you are sharing a tool that might help thousands more developers like you. And your tool might be improved on and mutated along the way by other open source contributors. This will help it grow into a life changing development tool that is freely available to everyone.

But when it comes down to it, how many companies would be happy for you to spend company dollars (and time) contributing to a tool? And not just any tool, one that could potentially help a competitor?

Well, you might be pleased to know that there are genuine business-driven reasons for a company to contribute to open-source, and we'll discuss just a few here.

Contributing to Open Source Helps Retain Top Talent

According to UnlockOpen , Facebook claims that 75% of their new engineering recruits mention their open source program as a key reason for joining the company.

And in a similar vein, by investing in Webpack and becoming active and public contributors to it, Trivago.com caught the attention of JavaScript developers, which helped it develop a reputation as an exciting company to work for.

This meant that instead of spending money on recruiters to find good developers, these companies invested that money in open-source. They were both doing something good and letting the good developers come to them.

Contributing to Open Source Attracts Developers to your Products or Services

By creating free open-source products, companies can often attract developers and get those developers to start using them. Then they can offer paid options for the upgraded or scaled versions.

For example, let’s take VSCode again, the free open-source text editor. It also has a paid IDE version called Microsoft Visual Studio for professional use.

As a developer, if you have used VSCode most of your life and know the tool and its UI/UX well, you might be more likely to upgrade to Visual Studio as a result. Not only because the experience is similar in terms of product, but you might feel a certain loyalty to the product after using its free version.

This strategy applies to many other open-source tools as well.

Contributing to Open Source Gives You a Net Competitive Advantage

When working at a particular company, a developer is often working on one codebase. One that they are very familiar with, or have lead in building themselves.

With this comes a sense of comfort but also complacency, as there are no new work styles thrown your way.

By contributing to external open-source projects, developers are building up their problem solving skills by being exposed to new issues and coding styles.

They're also practicing their communication skills, whether it's just by communicating with individuals from other companies, or individuals from different countries with different languages and cultures.

This paper presents a review of the Open Source development process from the point of view of the involvement of the developers in the production process. The study focuses on how developers contribute to projects in terms of involvement, size and kind of their contribution. Data have been collected from different kinds of open source projects and the results show that the general behavior is the same, even if projects and people are different.

Abstract Open Source Software (OSS) has become the subject of much commercial interest of late. Certainly, OSS seems to hold much promise in addressing the core issues of the software crisis, namely that of software taking too long to develop, exceeding its budget, and not working very well. Indeed, there have been several examples of significant OSS success stories—the Linux operating system, the Apache web server, the BIND domain name resolution utility, to name but a few.

Abstract. Open Source and Agile (eXtreme Programming, in particular) projects have several commonalities such as focus on the value for the user, continuous feedback, high level of communication, etc. Moreover, both approaches present difficulties in keeping track of the status of the development, verifying the quality of the production process, identifying best practices, etc. Such difficulties are related to the lack of a formal activity for the collection of data regarding the development process.

DARPA edges closer to using AI to expose cyber vulnerabilities

Ai in the workplace.

By David DiMolfetta

Next year, seven teams will compete to polish off a best-case model that meshes AI and cybersecurity to detect and fix open-source vulnerabilities in critical infrastructure.

• Cyber Threats
• Critical Infrastructure

LAS VEGAS — The Defense Advanced Research Projects Agency on Sunday selected seven teams to advance to the final stage of a U.S.-sponsored cybersecurity competition, where they will be tasked to finalize an AI-powered system designed to secure open-source software that underpins many critical infrastructure sectors, like banks and water systems.

The top seven scoring teams, who were each awarded $2 million for their work at the DEF CON hacker conference in Las Vegas, will have one year to build upon their systems before the DARPA-backed AI Cyber Challenge — or AIxCC — finale is held at next year’s DEF CON. 

The AIxCC, in partnership with the Advanced Research Projects Agency for Health, or ARPA-H, challenged participants to create AI systems to protect open-source software that supports critical sectors of the U.S. economy, including public utilities and healthcare.

Open-source tooling is free to use and convenient for critical infrastructure owners and operators. But it’s particularly vulnerable to cyber exploitation because the publicly available code allows attackers to easily identify and exploit weaknesses. If a hacker succeeds in infiltrating and leveraging a flaw in an infrastructure network, it may create cascading impacts on public health and safety.

As part of the competition’s rules, teams must agree to open-source their systems. The clause aims to accelerate the distribution and use of the AIxCC-developed technology within the cybersecurity and software development fields.

Some 39 teams competed, according to a summary provided by DARPA officials on Sunday. One group, Team Atlanta, found a previously undetected bug in SQLite , a popular language used to search through databases.

“We found that the open source software community is not resourced at an ideal level, given how often and how frequently that code makes its way into critical systems in power, water and healthcare all over the country,” Andrew Carney, program manager for AIxCC, told Nextgov/FCW in the DEF CON AIxCC hacking village, where the competition was being showcased.

Heather Adkins, Google’s vice president of security engineering who was also on site, said that fully jettisoning open-source tools from critical infrastructure systems as a protective measure would prove too complex an undertaking.

“The reality is that so many commercial solutions today have open source integrated into them,” she said, arguing it wouldn’t make sense to simulate environments that don’t reflect real life. A 2024 Open Source Security and Risk Analysis Report provided by Synopsys found open source components are present in more than 96% of over 1,000 commercial codebases, with 84% containing at least one known vulnerability.

In the contest, DARPA took real open-source software packages and intentionally inserted vulnerabilities into their code. Since organizers know exactly where and what types of flaws were added, they can precisely evaluate the competitors’ efforts. The contest employed advanced tools known as sanitizers — digital instruments that detect specific types of code defects — that are integrated into the modified open-source projects, making it easy to measure how teams have targeted specific vulnerabilities.

Some of the bugs were inspired by already-known vulnerabilities, but, in the spirit of real-world scenarios where hackers frequently modify and innovate on their techniques, many of them were newly-created, Carney said.

The competition was partly motivated by the advent of large language models over the past 18 months that are behind popular consumer-facing generative AI tools. Many of the major companies that have rolled out such offerings, including Anthropic and OpenAI, provided their model infrastructure to competitors at the hacking conference.

“We, among everybody else, are concerned about the risks of generative AI,” DARPA Director Stefanie Tompkins said in an interview. “We also are asking ourselves if we can use them for the power of good or how they can be harnessed to go after [cybersecurity] risks.”

The AIxCC competition would be a boon for the healthcare industry, said Renee Wegrzyn, who leads ARPA-H. Fronting an AI-powered cyber tool would hugely benefit small healthcare companies, in particular, because they are less resourced in technical staffing and expertise, she said. 

ARPA-H is just two years old, but a program like this is critical to the health sector, a favorite target of hackers because hospitals store sensitive patient data that, if pilfered, can be used for identity theft and fraud schemes. 

“Our mission is to accelerate better health outcomes, and with these vulnerabilities still being out there, that really impacts health outcomes of all Americans,” Wegrzyn said.

Numerous cases documented by intelligence officials indicate that nation-state groups — like China’s Volt Typhoon hacking collective — have breached American critical infrastructure. These hackers are preparing to disrupt systems and cause widespread panic or undermine military efforts if commanded by China’s central government, particularly in the context of increasing military activity centered on Taiwan, officials say.

And earlier this year, the open-source community faced a new type of threat when a user dubbed “Jia Tan” tried to quietly plant a backdoor into XZ Utils, a widely-used file transfer tool found in several Linux builds that power software in major companies that have global presence. Analysts say Jia Tan may have been a collection of nation-state hackers planning a long game to surreptitiously hijack the tooling.

Addressing open-source security has emerged as a key focus for the Biden administration. On Friday, the Office of the National Cyber Director published a report summarizing feedback from the security community on enhancing open-source security. A new DHS office also announced Friday would also aim to examine the volume of open source tooling based inside critical infrastructure and how best to secure it from hackers, CyberScoop reported .
