Secure Desktops with Qubes: Installation

Saturday, 28 May 2016 - 11:00 AM - (Security)

This is the second in a multipart series on the Qubes operating system. In my first article, I gave an overall introduction to Qubes and how it differs from most other desktop Linux distributions, namely in the way it focuses on compartmentalizing applications within different VMs to limit what attackers have access to in the event they compromise a VM. more>>

Linux at 25: Q&A With Linus Torvalds

Tuesday, 29 March 2016 - 15:56 PM - (Software)

The creator of the Linux open-source operating system talks about its past, present, and future.

The creator of the Linux open-source operating system talks about its past, present, and future. 

Linus Torvalds created the original core of the Linux operating system in 1991 as a computer science student at the University of Helsinki in Finland. Linux rapidly grew into a full-featured operating system that can now be found running smartphones, servers, and all kinds of gadgets. In this e-mail interview, Torvalds reflects on the last quarter century and what the next 25 years might bring.

Stephen Cass: You’re a much more experienced programmer now versus 25 years ago. What’s one thing you know now that you wish your younger self knew?

NetApp Updates its SANtricity OS, Targets Analytics Workloads

Tuesday, 29 March 2016 - 12:00 PM - (Enterprise)

NetApp on Tuesday said it has released a new version of its SANtricity storage operating system with the aim of speeding up analytics workloads. 

NetApp on Tuesday said it has released a new version of its SANtricity storage operating system with the aim of speeding up analytics workloads. The release of SANtricity, which powers the storage vendor's EF Series all-flash and E-Series storage arrays, is designed to improve performance of Splunk, Hadoop and NoSQL workloads.

Storage vendors are increasingly pitching all-flash arrays with the aim of garnering big data workloads. NetApp's move highlights how storage vendors are trying to ride the analytics wave be speeding up performance. NetApp said it is using proactive monitoring, automation and configurations for high-throughput apps to boost performance.

Hadoop Project ODP Regroups Under Linux Foundation's Umbrella

Tuesday, 29 March 2016 - 11:26 AM - (Enterprise)

The Open Data Platform's reorg aims to assuage criticism about untoward vendor control over the initiative to create a consistent baseline Hadoop distribution.

The Open Data Platform's reorg aims to assuage criticism about untoward vendor control over the initiative to create a consistent baseline Hadoop distribution.

After major criticism within the Hadoop community about its nature and aims, Open Data Platform -- an initiative to create a reference-standard Hadoop distribution for others to build from -- announced Monday it will now be hosted at the Linux Foundation as a Collaborative Project. The goal with this new organizational structure is to ameliorate the perception that the ODP Initiative is vendor-owned and -controlled, rather than just participated in by Hadoop vendors among many others.

OpenDaylight and ONOS: Does SDN Really Need Two Controllers?

Tuesday, 29 March 2016 - 11:15 AM - (Enterprise)

Perhaps the Internet has spoiled us: We’ve grown accustomed to single standards for global communication, or at least with choosing one way to communicate certain classes of data. The Web’s principal protocol is and always has been, some form of HTTP. When we built Web services and Web applications, we started with SOAP, and then we shifted to JSON for exchanging API calls. We’ve had several standards before, but we usually lean towards one at a time.

We’ve had several standards before, but we usually lean towards one at a time...

But in the field of software-defined networking, the open source community, working in concert with data center technicians and network engineers, have managed to boil down the centers of gravity among software-based controllers to a solid pair: ONOS, a project led by some of the creators of OpenFlow protocol, to enable scalable network functions on telcos’ infrastructure; and OpenDaylight, now used predominantly by data centers that host network functions using OpenStack.

New DDoS Defense Turns Servers Into "Moving Targets"

Tuesday, 29 March 2016 - 11:09 AM - (Enterprise)

The distributed denial-of-service (DDoS) attack is the classic cheap hack. It requires virtually nothing of those who wield it beyond the ability to download something from the internet, yet a DDoS offers unusually public consequences (most real security breaches happen in the dark).

The distributed denial-of-service (DDoS) attack is the classic cheap hack. It requires virtually nothing of those who wield it beyond the ability to download something from the internet, yet a DDoS offers unusually public consequences (most real security breaches happen in the dark). It is also difficult to defend against, in some part because it doesn't involve actually breaching a network at all—just flooding it with more innocuous-seeming traffic than it can handle.

As described in the current issue of IEEE Computer, security researchers from George Mason University have developed a new defensive strategy that they claim can thwart DDoS attacks through a process of client-server connection "shuffling."

Google Offers Rare Glimpse at Its Data Center Security Measures

Tuesday, 29 March 2016 - 08:18 AM - (Enterprise)

Laser beam intrusion detection systems, iris scanners, customized access cards are just some of the controls that Google uses to protect its data centers.

290x195googledatacenter5Laser beam intrusion detection systems, iris scanners and customized access cards are just some of the controls that Google uses to protect its data centers.

Other measures include dual authentication systems, vehicle-access barriers, high-resolution cameras, metal detectors, perimeter fencing and so-called circle-lock portals to prevent tailgaters from entering protected areas by following too closely behind someone with a valid access card. Access to the actual data center floors itself is often only possible through a security corridor featuring multifactor authentication systems.

Kubernetes 1.2 Offers Rolling Updates, Persistent Volumes

Tuesday, 29 March 2016 - 08:14 AM - (Enterprise)

At the Google GCP Next conference last week in San Francisco, the company demonstrated how it was possible with Kubernetes to update a heavily used distributed application while keeping that app running. For a Kubernetes 1.2 on-stage demo, Greg DeMichillie, director of program management for Google Cloud Platform spun up a service and then used load testing software to dispatch 20,000 requests-per-second to the service.

For a Kubernetes 1.2 on-stage demo, Greg DeMichillie, director of program management for Google Cloud Platform spun up a service and then used load testing software to dispatch 20,000 requests-per-second to the service. “Now if I did this demo 18 months ago, this would have been considered an amazing thing — who would have had the ability to run services at this scale? Now, it’s my ‘Hello World,’” DeMichillie said. 

The exercise was set to show off the latest capability of Kubernetes — to show how the software could update a service with zero downtime.
