Projects will have the opportunity to deliver lightning talks lasting 5-minutes during KubeCon + CloudNativeCon. This platform offers projects the chance to showcase their recent updates, features, and other highlights to their peers. The project lightning talks will be included in the conference schedule and are based on availability.

Because these talks are centered on the project rather than any individual speaker, complimentary passes are not provided. If you don’t already have a pass and are unable to secure funding to attend, we recommend applying for a scholarship. Alternatively, if you're unable to attend, we would still consider the talk if another project representative is available to present on your behalf.

A maximum of 1 speaker is allowed per Project Lightning Talk. Please do not submit more.

Linux Security Summit Europe 2025 is a technical forum for collaboration between Linux operating system developers, researchers, and end-users.

Its primary aim is to foster community efforts in deeply analyzing and solving Linux operating system security challenges, including those in the Linux kernel. Presentations are expected to focus intensely on new or improved technology and how it advances the state of practice for addressing these challenges.

We encourage snippets of source code or assembly code. Presentations marketing a product are out of scope. Presentations discussing software must focus on open source software (OSS) publicly viewable by CFP close; proprietary and unviewable software are out of scope. 

Presentations on other OSS operating systems can be relevant if there are lessons to be learned between them and Linux operating systems or if they are on algorithms or hardware and the focus is on Linux-specific implementation.

Suggested Topics

• Access Control
• Case Studies
• Cryptography and Key Management
• Emerging Technologies, Threats & Techniques
• Hardware Security
• IoT and Embedded Security
• Integrity Policy and Enforcement
• Open Source Supply Chain for the Linux OS
• Security Tools
• Security UX
