The term "open source" refers to software in the public domain that people can freely use, modify, and share. The adoption of third-party open source software (OSS) has increased significantly over the last few years to help augment proprietary code developed in-house and to accelerate time-to-market. Taking advantage of OSS projects can speed application development and help get compelling business applications to market faster. But the use of OSS also brings with it certain challenges that the organization needs to manage, such as balancing the risk/reward equation as you navigate the trade-offs between agility, quality, vulnerability, and software security.
Open source security refers to the tools and processes used to secure and manage OSS and compliance from development to production. The best of these automatically discover open source dependencies in your applications, provide critical versioning and usage information, and trigger alerts when risks and policy violations are detected anywhere across the SDLC. Then in production, they automatically monitor, block, and alert on attacks targeting any open source vulnerability so that you can take quick action.
There are two types of open software/open source projects:
Open source code> is used by companies in all industries and of all sizes. Aside from the widely-known open source operating systems on the market, such as Linux, FreeBSD, and OpenSolaris, enterprise users also leverage open source productivity software, tools for administrators and developers, and various source libraries used to build their own software.
Even commercial software is typically built to include open source code. As enterprises are moving to agile methodologies, open source projects become even more valuable, and there are more tools available for them. New software developers entering the market today are trained on open source use and are typically very comfortable with using open source technologies.
Aside from Red Hat, large financially strong open source software vendors are few and far between. Great products may come from smaller, more nimble companies, but there is a significantly higher risk that they won’t be there for the long term, making this a vulnerability to take seriously.
As far as security is concerned, the big win in using open source software should be transparency. Since there is “a community of eyes” working with and inspecting open source code coming from open source projects, there should be fewer bugs, with any flaw or vulnerability spotted and fixed quickly.
But there are two “gotchas” about the “many eyes” theory. First, by far the majority of projects are maintained by either a single developer or a small team of “volunteer” developers. How often they actually have the time and resources to look at and update their code is a complete unknown, and certainly not subject to any formal process. In other cases, the software may not be maintained at all. Those who create and contribute free software are under no obligation to maintain it. Indeed, most such software usually comes with some kind of “as is” disclaimer. The reverse side of that disclaimer is if the developer isn’t responsible for the code, then it is clearly the responsibility of users to “own their sources” and make sure the code is safe.
If you’re not actually a developer, you might be surprised at just how much of your organization’s software relies on open source components. Using community-produced software saves development time and cost, and allows organizations to essentially outsource maintenance to a worldwide community of organizations and volunteer developers. These wins have led to suggestions that there’s more open source code than proprietary code in the majority of organizational codebases, with on average a single codebase containing over 250 open source components.
Despite its obvious advantages, open source software (OSS) will always come with certain quality and security risks. So before taking advantage of OSS and deciding on your open source security strategy, it’s important to ask these questions:
Adopting OSS reduces overall development costs and frees developers to work on more value-added tasks. However, as companies use more open source code, they risk introducing vulnerabilities that predispose them to cyberattacks and breaches.
These stats give us a quick look at the OSS vulnerability/risk profile:
A major advantage of open source is its lower cost. And when there's a problem, the company can open up the code and fix it immediately rather than waiting for a vendor to respond. But the challenge is to tap into the advantages of open source without falling victim to any of its security traps.
Open source security tools are designed to manage OSS security and compliance from development to production. The best of these:
Applications that use OSS are a primary target for cybercriminals because once a vulnerability is discovered, adversaries can attack virtually any application built using that now-vulnerable OSS. This means software development, security, and operations teams must factor in and address the risk of OSS. And, with more of every business based on software, those software vulnerabilities represent tangible, and in some cases, significant business risks.
Digital transformation is driving the creation of more software, delivered faster. OSS helps meet the need for speed, but can also introduce unanticipated risk to the business. Contrast enables development and security teams to embed application security within the entire Software Development Life Cycle (SDLC) quickly and inexpensively from development, QA and production. Software becomes “self-protecting,” so applications built on OSS can be created and deployed into production faster across many environments without compromising on their security. Contrast Security is uniquely positioned to deliver affordable, automated application security solutions that address OSS risk at scale.
It’s important to recognize that free code comes at a cost, and that cost is responsibility. Businesses need to “own their sources,” because it is the business that will bear the brunt of any losses, both financial and reputational.
In order to ensure that your codebase is secure, you need visibility into your open source code dependencies as well as a very clear understanding of what that code is doing across your applications and systems. There are tools that can be used to audit open source code for known vulnerabilities and databases that can be searched for detailed information and remediation guidance. There are also AI driven solutions like Contrast OSS, that deliver automated open source risk management by embedding security and compliance checks in applications throughout the development process and then performing continuous monitoring in production. Contrast is the only solution that can identify vulnerable components, determine if they are actually used by the application, and prevent exploitation at runtime.
Contrast offers a DevSecOps solution to managing open source software risk. Contrast OSS works by deploying an intelligent agent that instruments the application with smart sensors to analyze code in real-time from within the application. Contrast is the only solution that can identify vulnerable components, determine if they are actually used by the application, and prevent exploitation at runtime. All of this information is streamed to security and development teams through the tools they already use, enabling short feedback loops and quick action.
Open source security empowers developers and development teams to use open source code confidently, taking advantage of the many benefits, while at the same time staying ahead of the risk curve to ensure that their organizations are protected.
Scale and ensure security while accelerating development with end-to-end automation: Contrast OSS discovers open source components in your applications automatically. It provides critical versioning and usage information, and triggers alerts when risks and policy violations are detected at any stage of the SDLC. In production, Contrast OSS monitors, blocks, and alerts on attacks.
Empower developers by catching issues early and enabling faster remediation: Contrast OSS enables early detection of vulnerabilities and open source license risk in the developer environment with continuous verification across CI/CD pipelines. Unlike legacy Software Composition Analysis (SCA) tools, Contrast OSS performs runtime analysis to accurately identify whether vulnerable components are actually used by the application.
Deploy the right security control to protect against known and zero-day exploits: Beyond automatically detecting risk, Contrast OSS provides runtime protection so attacks on vulnerable open source code are automatically monitored and blocked to prevent exploitation in production. Applications self-monitor and self-defend against attacks targeting open source components in production.
Continuous visibility and self-updating software risk intelligence: Contrast OSS monitors your entire application portfolio including third-party and custom code, automatically applying new vulnerability and license risk intelligence and policies. This eliminates the need for disruptive scans and re-scans of code repositories.
