AMD’s EPYC server encryption is the latest security system to fall

It’s a good thing AMD had the sense not to rub Intel’s nose in the Meltdown/Spectre vulnerability, because it would be getting it right back for this one: Researchers from the Fraunhofer Institute for Applied and Integrated Safety in Germany have published a paper detailing how to compromise a virtual machine encrypted by AMD's Secure Encrypted Virtualization (SEV).The news is a bit of a downer for AMD, since it just added Cisco to its list of customers for the EPYC processor. Cisco announced today plans to use EPYC in its density-optimized Cisco UCS C4200 Series Rack Server Chassis and the Cisco UCS C125 M5 Rack Server Node.To read this article in full, please click here

Is open source software a network security risk?

Networks are changing. More and more we’re hearing terms like whitebox, britebox, disaggregation, NOS, commodity hardware and open source when we talk about the future of networking. Since you’re reading this on the Cumulus Networks blog, I’ll assume you get that and spare you a description of these terms here. If you do want a crash course on network disaggregation and how it relates to orchestration/SDN, check out my previous post on the Packet Pushers blog.

With that bit of housekeeping out of the way, let’s dig right into today’s topic: open source software security.

First, why does security matter? If you’re like most network engineers, your primary goal typically is to get bits of data from one place to another. Anything that interferes with the free flow of packets and frames is a potential problem. So the goals of security can at first appear contrary to those of the network. Raise your hand if you’ve ever been frustrated by a firewall rule or some seemingly arcane security policy!

Unfortunately, we no longer have the luxury of ignoring security. Today’s network is one of the most crucial pieces of IT infrastructure for any organization and for the economies we operate in. Continue reading

Viewer’s Guide: Virtual Cloud Network Online Event

Start Building the Virtual Cloud Network Today, join the online event June 5 at 11am PDT

You might not know it yet, but your network is holding you back. Unconnected clouds and data silos prevent your enterprise from securing and mining valuable data. VMware creates connections from your data center to the cloud to the edge – providing a secure, consistent foundation that drives business forward, rather than holding it back.

VMware recently announced our vision for the next era of networking – the Virtual Cloud Network. Join us for an exclusive online event to learn about how your organization can start building the network of the future. To prepare for this event, I not only spent time with the customers, technical leads and executives you hear from, but also behind the scenes, I have been part of many more conversations that I was not able to share.  Pulling from those conversations, I’ve created your viewer’s guide for each segment of the event.

 

An overview of the Virtual Cloud Network by Rajiv Ramaswami, Chief Operating Officer, Products and Cloud Services

Rajiv and Pat share their executive views on the Virtual Cloud Network at the beginning of the event. To Continue reading

Study shows admins are doing a terrible job of patching servers

Open source has taken over the server side of things, but admins are doing a terrible job of keeping the software patched and up to date.Black Duck Software, a developer of auditing software for open-source security, has released its annual Open Source Security and Risk Analysis, which finds enterprise open source to be full of security vulnerabilities and compliance issues.[ For more on IoT security see our corporate guide to addressing IoT security concerns. | Get regularly scheduled insights by signing up for Network World newsletters. ] According to the study, open-source components were found in 96% of the applications the company scanned last year, with an average of 257 instances of open source code in each application.To read this article in full, please click here

IDG Contributor Network: Compelling ways the C-level can leverage the IoT

Across a variety of industries, corporate IT and operations teams are rapidly deploying IoT to meet core business objectives. The aim of these deployments can vary greatly, from monitoring device health, to reducing operating costs, and increasing production volume. Yet there are a number of other areas throughout an organization, with initiatives of equal importance, where stakeholders have yet to leverage the value of connected device data to achieve their goals. One such example is the C-level. While generally not designed with executives in mind, IoT technology can provide value to the C-level that’s on par with the advantages their IT and operations counterparts stand to gain.To read this article in full, please click here

IDG Contributor Network: 4 criteria enterprises use to pick best-in-class IoT device management

Everyone talks about the excitement of collecting reams of Internet of Things (IoT) data and performing Herculean statistical gyrations on them. IoT data management and analytics are very important: this is how we can accomplish predictive maintenance on factory assets, help robots interact better with humans, and get cars to drive themselves more safely than my 17 year old son behind the wheel.The wise know that IoT data management is relatively easy to implement, but successfully accomplishing IoT device management for heterogeneous devices in-bulk is like navigating your canoe past the sea monsters Scylla and Charybdis.What makes great IoT device management?To read this article in full, please click here

Nvidia’s HGX-2 brings flexibility to GPU computing

GPU market leader Nvidia holds several GPU Technology Conferences (GTC) annually around the globe. It seems every show has some sort of major announcement where the company is pushing the limits of GPU computing and creating more options for customers. For example, at GTC San Jose, the company announced its NVSwitch architecture, which connects up to 16 GPUs over a single fabric, creating one massive, virtual GPU. This week at GTC Taiwan, it announced its HGX-2 server platform, which is a reference architecture enabling other server manufacturers to build their own systems. The DGX-2 server announced at GTC San Jose is built on the HGX-2 architecture.To read this article in full, please click here
