An open guide to evaluating software composition analysis tools

November 2, 2020

Overview

With the help of software composition analysis (SCA) tools, software development teams can track and analyze any open source code brought into a project from a licensing compliance and security vulnerabilities perspective. Such tools discover open source code (at various levels of details and capabilities), their direct and indirect dependencies, licenses in effect, and the presence of any known security vulnerabilities and potential exploits. Several companies provide SCA suites, open source tools, and related services driven as community projects. The question of what tool is most suitable for a specific usage model and environment always comes up. It is difficult to answer given the lack of a standard method to compare and evaluate such tools.

The goal of this paper is to recommend a series of comparative metrics when evaluating multiple SCA tools.

If you’re reading this, you more than likely are aware of the struggles involved in recruiting and building a team of technical professionals skilled in cloud-native computing technologies such as Kubernetes, Helm, Prometheus, and service mesh. The Linux Foundation and edX’s “2020 Open Source Jobs Report” found 93% of hiring managers are having difficulties filling open positions that require open source skills like these. The report also found that cloud and container technologies are the most in-demand aside from Linux, which itself is a necessary basic skill for cloud professionals.

So the question is, between a talent shortage and rapidly increasing adoption of these technologies, how can any leader manage to build out a qualified team? Based on our experiences as a vendor-neutral provider of training and certification for many of these technologies, we’ve learned some tips and tricks that, with some effort, can help you establish a team that can handle any cloud-native project you throw at them.
