Intel, IBM, Google, Microsoft & others join new security-focused industry group

 New Confidential Computing Consortium will promote the use of TEEs (trusted execution environments).

Some of the biggest names in the cloud and hardware ecosystem have agreed to join a new industry group focused on promoting safe computing practices.

Founding members include Alibaba, Arm, Baidu, Google Cloud, IBM, Intel, Microsoft, Red Hat, Swisscom, and Tencent.


Named the Confidential Computing Consortium, this industry group's goals will be to come up with strategies and tools to accelerate the adoption of "confidential computing."

By confidential computing, the group is referring to hardware and software-based technical solutions for isolating user data inside a computer's memory while it's being processed, to avoid exposing it to other applications, the operating system, or other cloud server tenants.

The easiest way of supporting confidential computing practices is through the use of trusted execution environments (TEEs), also known as enclaves.

These are hardware and/or software-enforced private regions of a computer's CPU memory where only certain apps can write and read data.

TEEs are often used in cloud computing, where cloud service providers use enclaves to safeguard a customer's data while it's being processed on cloud servers that are often shared by multiple users.

However, even the most mundane apps, such as the ones running on a laptop or smartphone, can use enclaves if they want to make sure other apps can't access a user's most sensitive data -- e.g. password managers, browsers, mobile wallets.

Promoting the use of TEEs will be one of the Confidential Computing Consortium main objectives. Members will help achieve this by contributing open-source tools that make working with enclaves much easier, by creating regulatory standards, and by running educational campaigns among their customers and the developer community.

As part of today's launch, Intel, Microsoft, and Red Hat announced they were contributing three open-source tools to the new consortium.

  • Intel® Software Guard Extensions (Intel® SGX) Software Development Kit, designed to help application developers protect select code and data from disclosure or modification at the hardware layer using protected enclaves.
  • Microsoft Open Enclave SDK, an open source framework that allows developers to build Trusted Execution Environment (TEE) applications using a single enclaving abstraction. Developers can build applications once that run across multiple TEE architectures.
  • Red Hat Enarx, which provides a platform abstraction for Trusted Execution Environments (TEEs) enabling creating and running "private, fungible, serverless" applications.

All these tools have been available as open source projects for years. By contributing, ZDNet asumes they are to be transfered under the governence of this new consortium, which will have the ability to steer their development on commonly-agreed paths, rather than each one being developed individually by their original creators.

A tool missing from this line-up is Google Cloud's Asylo. Just like the three tools above, Asylo was developed by Google Cloud engineers as an open-source framework and SDK for developing applications that run in trusted execution environments (TEEs). There was no formal announcement that Asylo will be transfered from Google Cloud's leadership to the new consortium.

The Confidential Computing Consortium's creation was announced today by the Linux Foundation, who will oversee its activities.

  Source of the data breach appears to be the country's National Revenue Agency A mysterious hacker has stolen the personal details of millions of Bulgarians and has emailed download links to the stolen data to local news publications. The data's origin is believed to be the country's National Revenue Agency (NRA), a department of the Bulgarian Ministry of Finance. In a  message posted on its website  on Monday, the NRA said it was working with the Ministry of the Interior and the State Agency for National Security (SANS) to investigate the hack. "We are currently verifying whether the data is real," said the NRA. Hours after this article's publication, the Bulgarian Ministry of the Interior  confirmed the hack . HACKER STOLE 110 DATABASES, LEAKED 57 According to reports from local media [ 1 ,  2 ,  3 ,  4 ,  5 ], who received part of the data, the hacker said they stole the personal details of over five million Bulgarians, of the country's total ...

​Linux totally dominates supercomputers

It finally happened. Today, all 500 of the world's top 500 supercomputers are running Linux. Linux rules supercomputing. This day has been coming since 1998, when Linux first appeared on the TOP500 Supercomputer list . Today it finally happened:  All 500 of the world's fastest supercomputers are running Linux . The last two non-Linux systems, a pair of Chinese IBM POWER computers running AIX, dropped off the  November 2017 TOP500 Supercomputer list . Overall, China now leads the supercomputing race with 202 computers to the US' 144. China also leads the US in aggregate performance. China's supercomputers represent 35.4 percent of the Top500's flops, while the US trails with 29.6 percent. With an anti-science regime in charge of the government, America will only continue to see its technological lead decline. When the  first Top500 supercomputer list was compiled in June 1993 , Linux was barely more than a toy. It hadn't even adopted Tux as its masc...

Microsoft tries to stem its self-made collaboration-tool confusion

Microsoft is using this week's Ignite conference to try to help clarify its collaboration-tool strategy. Here's how SharePoint, Teams and Yammer figure in the mix. Choice is good. But too much choice, especially when it comes to collaboration tools, has been a problem for Microsoft. This isn't news to customers, partners or Microsoft execs themselves. But at the company's Ignite IT Pro conference in Orlando this week, Microsoft execs took a step to try to clarify the company's strategy and messaging in this area. Microsoft Office 365 Marketing chief Ron Markezich kicked off the conference this week with a slide entitled "Microsoft 365 Teamwork: Where to Start a Conversation." That slide attempts to do what  Microsoft initially attempted with a 60-plus-page whitepaper : Clarify which collaboration tools customers should use when. The slide, which features SharePoint -- and its files, sites and content storage at the center -- is broken down into t...
