Red Hat OpenShift sandboxed containers 1.10 has been released, bringing enhanced security and isolation capabilities to your Red Hat OpenShift environments. This marks the general availability of confidential containers on Microsoft Azure, and introduces the new Red Hat build of Trustee, which provides attestation services so your confidential workloads can run with integrity in the cloud. OpenShift sandboxed containers delivers a lightweight and powerful way to run workloads in isolation. Confidential containers add an additional layer for hardware-protected environments, leveraging Trusted E

In enterprise Kubernetes environments, security risks often arise from overlapping administrative access. Platform engineers, infrastructure operators and developers may all touch sensitive resources, like secrets. This creates opportunities for privilege misuse or data exposure. By separating admin duties using Confidential Containers, organizations can prevent insider threads, simplify compliance, and align with zero-trust principles.Kubernetes role-based access control (RBAC) enforces access policies by defining roles and permissions for users, groups, and service accounts. It allows you to

When you subscribe to Red Hat Enterprise Linux (RHEL), you get security fixes for Common Vulnerabilities and Exposures (CVE). As defined in the RHEL Life Cycle Policy, we classify any issue rated with a Common Vulnerability Scoring System score of 7.0 or higher as Critical, Important or Moderate. Our enhanced support plans (RHEL Extended Life Cycle Support, Extended Update Support, and Enhanced Extended Update Support) include similar coverage. But compliance in finance, healthcare, telecommunications, the public sector and other highly regulated industries may demand fixes and patches outsid

Model Context Protocol (MCP) is a powerful protocol from Anthropic that defines how to connect large language models (LLMs) to external tools. It has quickly gained traction due to its ease of use and the benefits it adds in our use of AI. In this article we'll cover some of the potential security risks you'll encounter with MCP and how you can approach mitigating them.How MCP worksMCP does not directly connect LLMs with tools. The MCP client component accesses the LLM, and the MCP server component accesses the tools. One MCP client has access to one or more MCP servers. Users may connect any

Open source has always been paradoxical: it's software developed by passionate developers and given away for free, yet it's monetized and funded by some of the largest companies in the world. An underdog, once called "a cancer," and yet it's the single largest driver of innovation and technological progress we have ever seen. In the world of open source, paradox will always exist, but nowhere more so than in the understanding of security vulnerabilities.Twenty-five years ago, the Common Vulnerabilities and Exposures (CVE) program was established to standardize the naming and tracking of softw
