gVisor Architecture and Integration
"gVisor Architecture and Integration" "gVisor Architecture and Integration" delivers a comprehensive, technical exploration of gVisor’s unique approach to container isolation within cloud-native environments. The book opens by contextualizing modern container security challenges, tracing the genesis of gVisor as a robust, open-source project tailored to address industry demands for stronger multi-tenancy and workload containment. It contrasts gVisor’s user-space kernel model against alternative technologies—such as runc, Kata Containers, and Firecracker—clarifying its distinct position in the ecosystem and its isolation guarantees across typical deployment scenarios, from the cloud to the edge. At its core, the text meticulously examines gVisor’s internal architecture, illuminating critical components like the Sentry user-space kernel, Gofer file and network mediator, syscall interception mechanisms, and their interplay in sandboxing containerized workloads. Readers gain an in-depth understanding of gVisor’s strategies for emulating kernel constructs—spanning process namespaces, virtual memory, filesystem mediation, and a full user-space TCP/IP stack—alongside performance optimization, observability, and real-world security hardening. The book demystifies the challenges of device emulation, syscall coverage, and the need for careful attack surface reduction, detailing both limitations and robust mitigations. Designed as both a practical integration guide and technical reference, the book moves seamlessly from first principles to advanced operationalization. It outlines the integration of gVisor with major orchestration tools like Kubernetes and Docker, explores continuous deployment and DevOps workflows, and provides actionable case studies from production deployments. Dedicated chapters on performance tuning, cluster-wide monitoring, and community-driven development empower readers to troubleshoot, extend, and contribute to gVisor’s ongoing evolution—making this essential reading for cloud architects, security engineers, system developers, and anyone invested in the future of secure, scalable container infrastructure.
Gvisor-seccomp Security Profiles
"Gvisor-seccomp Security Profiles" "Gvisor-seccomp Security Profiles" is an authoritative guide for practitioners, architects, and engineers seeking to master the intricate art of securing Linux containers using gVisor and seccomp policies. Beginning with the foundational elements of container and sandbox security, the book examines the theory and practice behind Linux namespaces, cgroups, and capabilities, then moves into the emergence of application-aware sandboxes and the technical underpinnings of gVisor's user-space kernel. Readers gain a thorough understanding of the system call attack surface, security boundary design in multi-tenant environments, and the layered roles of tools such as SELinux and AppArmor. Delving into both the mechanics of seccomp in Linux and the distinct features of gVisor, the book offers detailed discussions of syscall filtering, policy grammar, performance implications, and the architectural philosophy driving gVisor’s approach to isolation and compatibility. Each chapter is meticulously structured to cover practical aspects—such as authoring, deploying, and maintaining robust security profiles for dynamic workloads—while also addressing advanced engineering concerns, including policy chaining, contextual filtering, and seamless orchestration with complementary security modules. Real-world vulnerabilities, evasion techniques, threat modeling, and defensive architectures are contextualized with case studies, formal verification strategies, and incident response playbooks tailored for sandboxed environments. Moving beyond technical implementation, "Gvisor-seccomp Security Profiles" addresses the challenges of operationalizing and scaling security policy in production. Through guidance on automation, integration with CI/CD pipelines, observability, and multi-tenancy governance, it arms readers with actionable insights for policy management at enterprise and hyperscaler scale. The book concludes by surveying future trends and research in the field—such as kernel evolution, automated policy synthesis, hardware-assisted isolation, and community-driven benchmarks—making it a comprehensive and indispensable resource for anyone invested in the security of modern containerized workloads.
Proceedings of the Future Technologies Conference (FTC) 2020, Volume 2
This book provides the state-of-the-art intelligent methods and techniques for solving real-world problems along with a vision of the future research. The fifth 2020 Future Technologies Conference was organized virtually and received a total of 590 submissions from academic pioneering researchers, scientists, industrial engineers, and students from all over the world. The submitted papers covered a wide range of important topics including but not limited to computing, electronics, artificial intelligence, robotics, security and communications and their applications to the real world. After a double-blind peer review process, 210 submissions (including 6 poster papers) have been selected to be included in these proceedings. One of the meaningful and valuable dimensions of this conference is the way it brings together a large group of technology geniuses in one venue to not only present breakthrough research in future technologies, but also to promote discussions and debate of relevant issues, challenges, opportunities and research findings. The authors hope that readers find the book interesting, exciting and inspiring.
