It allows developers to create tailored sandbox environments for various programming languages and supports integration with AI tools for rapid development and deployment of applications. With features like project-based management and temporary sandboxes, microsandbox enhances productivity while ensuring code safety.

Red Hat OpenShift Virtualization, combined with HashiCorp Vault, addresses the secret zero problem in virtualized infrastructures by establishing machine identities for VMs. The article explores how to implement secure introductions and leverage Kubernetes-native patterns to enhance security and streamline operations for virtual machines.

NovaHypervisor is a defensive x64 Intel hypervisor designed to protect against kernel-based attacks by safeguarding memory structures and defense products on Windows 10 and later. Written in C++ and Assembly, it is in early development, not yet suitable for production, and includes instructions for setup, memory protection commands, and logging. Users must enable specific virtualization features to run the hypervisor effectively.

The article presents Katakate's k7, a self-hosted infrastructure designed for creating lightweight virtual machine (VM) sandboxes to safely execute untrusted code. It supports a command-line interface, API, and Python SDK, leveraging technologies like Kubernetes, Kata, and Firecracker for efficient VM management. Currently in beta, it offers features for serverless applications, CI/CD runners, and blockchain execution, while being open-source under the Apache-2.0 license.
