Security Technical Advisory Group

Cloud Native Security Logo


The CNCF Security Technical Advisory Group facilitates collaboration to discover and produce resources that enable secure access, policy control, and safety for operators, administrators, developers, and end-users across the cloud native ecosystem.


Cloud Native describes the building, deploying, and operating of modern applications in cloud computing environments, typically using open source. This complex ecosystem composed of different open source projects presents an increasingly complicated technology risk landscape. While there are several projects in the cloud native ecosystem that address trust, safety, and security in the dynamic interplay between the different layers of infrastructure and application services, the technological shift demands application and information security be rethought through the lens of developer experience as close to applying software engineering to design for security considerations in the effort to safeguard an integrated cloud native ecosystem as a whole.


We believe in a future where the probability and impact of attacks, breaches, and compromises are significantly reduced. Where the most common risks of today are not just mitigated but made implausible. We believe developers and operators can be empowered to understand better and be reassured by the posture of the systems they build and run through the informed use of cloud technologies with clear understanding of responsibility and risks and the unlocked ability to validate that their architectural intent meets compliance and regulatory objectives.

There is a growing ecosystem of tools that promises to unlock developer productivity and operational efficiency. We strive to fulfill the human side of the sociotechnical equation to acceleration and attain that promise including:

  1. Consumable system security architectures that account for the ever growing heterogeneity of systems and provides a framework to protect resources and data while servicing their users.
  2. Common lexicon and open source libraries that make it easy for developers to create and deploy apps that meet system security requirements.
  3. Common libraries and protocols that enable people to reason about the security of the system, such as auditing and explainability features.


TAG Security has published several resources for the community, which can be found in the publications document.


Security TAG charter outlines the scope of our group activities, as part of our governance process which details how we work.


Anyone is welcome to join our open discussions of Security TAG projects and share news related to the group’s mission and charter. Much of the work of the group happens outside of Security TAG meetings and we encourage project teams to share progress updates or post questions in these channels:

On-going projects

Compliance Working Group

Compliance Working Group is cross-disciplinary and focused on bridging purely technical issues to broader legal and regulatory workflows: not only the prevention of system breaches, but also considering supply chain, operators, data and AI failures while simultaneously considering auditability, non-repudiation, legally required forensic evidence, etc. - across all the various activities required of cloud native operators of all sizes. The Compliance WG plans to curate vendor neutral tools for evidence collection, chain-of-custody in audits, as well as automated workflows for continuous compliance authoring and assessment.

Weekly meetings at 10:00 AM ET (60 min) Check My Time

Security reviews

Security reviews are a collaborative process for the benefit of cloud native projects and prospective users by creating a consistent overview of the project and its risk profile.

Facilitator: Justin Cappos ( @JustinCappos), New York University

Co-chair representatives: @sublimino @PushkarJ

Software Supply Chain Security

Software Supply Chain attacks have come to the wider community’s attention following recent high-profile attack, but have been an ongoing threat for a long time. With the ever growing importance of free and open source software, software supply chain security is crucial, particularly in cloud native environments where everything is software-defined.

Weekly meetings at 8:00 AM PT (50 min) (see your timezone here) See CNCF calendar for invite.

Facilitator for current deliverables is listed on the issue
