Slack Releases Open Source Secure Development Lifecycle Tool

Team collaboration solutions provider Slack last week announced that one of the secure development lifecycle (SDL) tools used internally by the company has been released as open source.

The tool, named goSDL, is a PHP-based web application designed to provide developers and project managers a list of questions and checklists that should help them improve the security of new software and features. It is meant to be used at the middle or near the end of a project.

After providing some general information about their project, developers using goSDL are instructed to answer some questions for an initial risk assessment. Among other things, developers are asked if they believe the involvement of the security team is necessary, and if their code adds new authentication features or changes existing security controls.

Once the initial assessment has been completed, goSDL requires developers to provide information about the components they are using, including web technologies, programming languages, and parsers. New components can be easily added to the questionnaire via JSON plugins.

Based on the responses provided in the previous phases, goSDL then generates security checklists that are relevant to the project. For tracking purposes, two JIRA tickets are created – one for the developer and one for the security team, allowing it to track its own review.

“The tool tailors the checklist to the developers’ specific needs, without providing unnecessary unrelated security requirements. Security experts can establish custom security guidance and requirements as checklist items for all developers,” Slack said. “This checklist is used as a guide and reference for building secure software. This encourages a security mindset among developers when working on a project and can be used to easily track the completion of security goals for that project.”

goSDL can be used with Atlassian’s Jira Enterprise issue tracker and the Trello project management application. The goSDL source code, along with usage instructions, can be found on GitHub.

“By open-sourcing goSDL, we hope to enable other growing organizations to scale their security. We also hope to learn from their experience; we welcome contributions to the tool, its modules, and its checklists, and are excited to see what pull requests will come in!” said Max Feldman of the Slack Product Security team.
