When you run a workload as a VM, container or in a serverless environment, that workload is vulnerable to interference by any person or software with hypervisor, root or kernel access. Enarx, a new open source project, aims to make it simple to deploy workloads to a variety of trusted execution environments (TEEs) in the public cloud, on your premises or elsewhere, and to ensure that your application workload is as secure as possible.
When you run your workloads in the cloud, there are no technical barriers to prevent the cloud providers–or their employees–from looking into your workloads, peeking into the data, or even changing the running process. That’s because when you run a workload as a VM, container or serverless, the way that these are implemented means that a person or software entity with sufficient access can interfere with any process running on that machine.

As people move workloads to shared and public cloud environments, what methods are available to attest their environment has not been tampered with? Is there a good way to use a standardized cryptographic module to do remote attestation, trusted system boot, and so on?
In this post we’ll introduce the Keylime project in some detail, and save a technology demo for a following hands-on article.
Keylime is an open source community-based project endeavoring to be the go-to technology for establishing and maintaining trusted infrastructure in distributed system deployments via two technologies: the use of embedded Trusted Platform Module (TPM) hardware (version 2 and later); and the Linux kernel subsystem – Integrity Measurement Architecture (IMA).

In this video from the Red Hat Summit 2018, Chief Security Architect Mike Bursell takes an enthusiastic look at three open source security technologies: DevSecOps, serverless computing, and Trusted Execution Environments.
These technologies are examples of where Red Hat’s longview is aimed for the security realm.

The goal of the Keylime project is to connect the features of Trusted Platform Modules (TPMs) and cloud computing. Keylime is a scalable trusted cloud key management system, providing an end-to-end solution for both bootstrapping hardware-rooted cryptographic identities for Infrastructure-as-a-Service (IaaS) nodes and for system-integrity monitoring those nodes via periodic attestation. Keylime extends the attestation capabilities of the TPM into the cloud, allowing tenants to verify that their applications, operating systems, and everything down to the hardware have not been tampered with.
A TPM (Trusted Platform Module) is a chip, present in most modern computers, that can perform various cryptographic statements in a tamper-proof fashion. In particular, through UEFI secure boot, a TPM can be used to verify at boot time that anything from the firmware up through the kernel and applications has not been modified from what the distributor originally shipped.

At the first signs of Spring, all Red Hatters turn at least one eye toward Red Hat Summit. Over the years, we’ve had many conversations with attendees about what kind of information and perspectives they’d like to hear at Summit. We learned that attendees appreciated the actionable technical information they received, but that they were interested in getting some insight into Red Hat’s point of view on emerging technology trends and their thoughts on the future. That was the motivation behind a new set of sessions from the Office of the CTO that we’re very excited to announce.

Blockchain is everybody’s latest buzzword–right up there with AI and IoT–but what does it mean, and how is it relevant to the enterprise?
The answer to those questions is likely “a lot,” but before we get to that, let’s define what a blockchain is–and isn’t.

If you could visualize the code that comprises our current technology landscape, you might imagine in your mind’s eye a glowing field of interconnected lines with bright bits of information flowing along the lines’ paths. Here and there, you might see flaws in the network–places where human error have introduced gaps and openings among the lines.
