What Is the Security Slam?

The Open Source Security Foundation (OpenSSF) is partnering with the Cloud Native Computing Foundation (CNCF) Security Technical Advisory Group (TAG Security) to support the 2026 Security Slam at KubeCon + CloudNativeCon America. 

The 30-day challenge runs from October 5 through November 6 and highlights OpenSSF projects as practical tools that help improve project security posture. Participants will use OpenSSF projects, among others, to achieve security hygiene milestones tailored to their project’s maturity level.

OpenSSF project leads, staff, and maintainers have assisted in the creation of the “Slam Library,” a set of web resources to guide participants through each challenge, and will continue to be available throughout the month via the official Security Slam website.

How to Participate

Register now to receive reminders and instructions before the event kicks off on October 5. Stop by the OpenSSF booth #313 in the KubeCon Solutions Showcase anytime during the week of November 10-12 to pick up participant achievement awards.

A Growing Community Effort

The Security Slam is a CNCF community activity that has taken many different shapes over the years. Now on its sixth iteration, the Slam is designed to help projects understand and improve their high level security posture.

Expanded Eligibility

Previously limited to CNCF projects due to the nature of the evaluation tools available, the Slam is now taking advantage of new tools to greatly broaden the qualifications for participation: Any open source project is invited to participate!
