Confidential containers (CoCo) is a new feature of Red Hat OpenShift sandboxed containers that leverages Trusted Execution Environment (TEE) technology to isolate your containers from the host and other containers. In this blog post, you will learn how to set up OpenShift sandboxed containers with confidential containers support on an OpenShift cluster hosted on Azure, using AMD SEV-SNP technology. You will also see how to create and run a confidential container that can process confidential data more securely and efficiently. For more information on confidential containers running on Az
When we started the discussions on the requirements that led to the development of Hirte (introduced by Pierre-Yves Chibon and Daniel Walsh in their blog post), we explored using systemctl with its --host parameter to manage systemd units on remote machines. However, this capability requires a secure shell (SSH) connection between the nodes, and SSH is too large of a tunnel. Instead, Hirte was created using transmission control protocol (TCP) based manager-client communication between the machines. Since Hirte manages systemd units, it uses the D-Bus protocol and the sd-bus application prog
This article is the fourth in a six-part series where we present various use cases for confidential computing—a set of technologies designed to protect data in use, like memory encryption, and what needs to be done to get the technologies’ security and trust benefits. In this article, we will focus on establishing a chain of trust and introduce a very simple pipeline called REMITS that we can use to compare and contrast various forms of attestation using a single referential. Part 1: Confidential computing primer Part 2: Attestation in confidential computing Part 3: Confidential
The software supply chain has quickly become the latest target for malicious actors, with targeted attacks on foundational software components intended to orchestrate data breaches, initiate service outages or worse. Today, we announced the release of Red Hat Trusted Software Supply Chain for businesses to more consistently code, build and monitor a trusted supply chain within their software factory. This allows software development teams and their business leaders to maintain and grow user trust. Why software supply chains matter Development teams rely on open source technology to keep
Red Hat OpenShift sandboxed containers has taken a significant step forward in workload and data security by adopting the components and principles of the CNCF Confidential Containers (CoCo) open source project and the underlying Trusted Execution Environment (TEE) technology. The first blog in the series introduced the OpenShift sandboxed containers with support for confidential containers solution on Microsoft Azure and targeted use cases. Learn more about Confidential Containers In this blog, we're focusing on the specifics of the CoCo components. We'll break down the major elements,
This article is the third in a six-part series (see our previous blog), where we present various usage models for confidential computing, a set of technologies designed to protect data in use—for example using memory encryption—and the requirements to get the expected security and trust benefits from the technology. In this third article, we consider the four most important use cases for confidential computing: confidential virtual machines, confidential workloads, confidential containers and confidential clusters. This will allow us to better understand the trade-offs between the
This article is the second in a six-part series (see our previous blog), where we present various usage models for confidential computing, a set of technologies designed to protect data in use—for example using memory encryption—and the requirements to get the expected security and trust benefits from the technology. In this second article, we will focus on attestation, as a method to prove specific properties of the system and components being used. The need for attestation In a confidential computing environment, another form of proof called attestation becomes increasingl

<p>Red Hat security data is a central source of truth for Red Hat products regarding published, known vulnerabilities. The availability of accurate information in security data can help provide the correct risk assessment process in customers' vulnerability management programs, which further helps with vulnerability patching prioritization. We work diligently to continuously improve our security data by adding more information to the existing data, introducing new data formats and cooperating with other vendors, including security scanner vendors, regarding the general a
<p>Despite Kubernetes still being a relatively young technology, adoption rates have soared over the past several years as the container orchestration platform has become the cornerstone for many digital transformation initiatives. Even as organizations settle in with their use of the technology in production, however, there still remains concern around the best ways to secure containerized workloads.
