In July 2022, the KubeEdge community completed a third-party security audit of KubeEdge and released a paper on cloud native edge computing security threat analysis and protection. Based on the security threat model and audit suggestions, the community consistently strengthens the KubeEdge software supply chain. Now, we are excited to announce that KubeEdge v1.13.0 (including both binary and container image artifacts), released on January 18, 2023, achieves SLSA 3 compliance, first of its kind in the CNCF community.

Why Is SLSA 3 Compliance Important to KubeEdge

Software supply chain integrity attacks (unauthorized modification of software packages) have been increasing in the past three years. After KubeEdge reaches SLSA 3, the E2E security (from source code build to release) is hardened, preventing malicious tampering of binary and container image artifacts. Thanks to SLSA, we can enhance the integrity of software artifacts, against tampering or any type of unauthorized modification of the software or software package, and enable software to defend against common supply chain attacks.

Abstract

The population of KubeEdge brings in community interests in the scalability and scale of KubeEdge. Now, Kubernetes clusters powered by KubeEdge, as fully tested, can stably support 100,000 concurrent edge nodes and manage more than one million pods. This report introduces the metrics used in the test, the test procedure, and the method to connect to an ocean of edge nodes.

As the first cloud-native edge computing community, KubeEdge provides solutions for cloud-edge synergy and has been widely adopted in industries including Transportation, Energy, Internet, CDN, Manufacturing, Smart campus, etc. With the accelerated deployment of KubeEdge in this area based on cloud-edge synergy, the community will improve the security of KubeEdge continuously in cloud-native edge computing scenarios.

The KubeEdge community attaches great importance to security and has set up Sig Security and Security Team to design KubeEdge system security and quickly respond to and handle security vulnerabilities. To conduct a more comprehensive security assessment of the KubeEdge project, the KubeEdge community cooperates with Ada Logics Ltd. and The Open Source Technology Improvement Fund performed a holistic security audit of KubeEdge and output a security auditing report, including the security threat model and security issues related to the KubeEdge project. Thank you to experts Adam Korczynski and David Korczynski of Ada Logics for their professional and comprehensive evaluation of the KubeEdge project, which has important guiding significance for the security protection of the KubeEdge project. Thank you Amir Montazery and Derek Zimmer of OSTIF and Cloud Native Computing Foundation (CNCF) who helped with this engagement.

The discovered security issues have been fixed and patched to the latest three minor release versions (v1.11.1, v1.10.2, v1.9.4) by KubeEdge maintainers according to the kubeedge security policy. Security advisories have been published here.

KubeEdge is an open source system extending native containerized application orchestration and device management to hosts at the Edge. It is built upon Kubernetes and provides core infrastructure support for networking, application deployment and metadata synchronization between cloud and edge. It also supports MQTT and allows developers to author custom logic and enable resource constrained device communication at the Edge.
