Secure your SDN controller

By Mark Dargin

Managing networks has become increasingly complex, and it will remain a challenge as the use of Internet of Things devices continues to grow. This complexity makes it difficult to reconfigure a traditional network in a timely manner to respond to malicious events or fix configuration errors.

A software-defined network (SDN) can help by giving network engineers the flexibility to dynamically change the behavior of a network on a node-by-node basis — something not typically available in a traditional network. An SDN uses virtualization to simplify the management of network resources and offers a solution for increased capacity without significantly increasing costs.

Top network monitoring software and visibility tools

By Brandon Butler

Networking performance monitoring and diagnostics (NPMD) software, whether running as an independent appliance or embedded in networking equipment, can help stave off productivity issues for internal corporate users as well as those interacting with the network from the outside.

But with ever-increasing traffic on corporate networks, users attempting to optimize connections to the cloud and new Internet of Things devices bombarding the network, enterprises and network performance monitoring vendors face growing challenges.

Level 3: Lessons From Recent DDoS Attacks

By Mitch Wagner Internet of Things devices are becoming attack vectors, and the situation will only get worse with the proliferation of devices and malware, as well as the spread of toolkits that hackers can use to create attacks.

Nvidia’s Huang Sees AI ‘Cambrian Explosion’

By George Leopold

The processing power and cloud access to developer tools used to train machine-learning models are making artificial intelligence ubiquitous across computing platforms and data framework, insists Nvidia CEO Jensen Huang.

One consequence of this AI revolution will be “a Cambrian explosion of autonomous machines” ranging from billions of AI-power Internet of Things devices to autonomous vehicles, Huang forecasts.

Along with a string of AI-related announcements coming out of the GPU powerhouse’s annual technology conference, Huang used a May 24 blog post to tout the rollout of Google’s (NASDAQ: GOOGL) latest iteration of its TensorFlow machine-learning framework, the Cloud Tensor Processing Unit, or TPU.

The combination of Nvidia’s (NASDAQ: NVDA) new Volta GPU architecture and Google’s TPU illustrates how—in a variation on a technology theme—”AI is eating software,” Huang asserted.

Arguing that GPUs are defying the predicted end of Moore’s Law, Huang further argued: “AI developers are racing to build new frameworks to tackle some of the greatest challenges of our time. They want to run their AI software on everything from powerful cloud services to devices at the edge of the cloud.”

Along with the muscular Volta architecture, Nvidia earlier this month also unveiled a GPU-accelerated cloud platform geared toward deep learning. The AI development stack runs on the company’s distribution of Docker containers and is touted as “purpose built” for developing deep learning models on GPUs.

That dovetails with Google’s “AI-first” strategy that includes the Cloud TPU initiative aimed at automating AI development. The new TPU is a four-processor board described as a machine- learning “accelerator” that can be accessed from the cloud and used to train machine-learning models.

Google said its Cloud TPU could be mixed-and-matched with the Volta GPU or Skylake CPUs from Intel (NASDAQ: INTC).

Cloud TPUs were designed to be clustered in datacenters, with 64 stacked processors dubbed “TPU pods” capable of 11.5 petaflops, according to Google CEO Sundar Pichai. The cloud-based Tensor processors are aimed at computer-intensive training of machine learning models as well as real-time tasks like making inferences about images

Along with TensorFlow, Huang said Nvidia’s Volta GPU would be optimized for a range of machine-learning frameworks, including Caffe2 and Microsoft Cognitive Toolkit.

Nvidia is meanwhile releasing as open source technology its version of a “dedicated, inferencing TPU” called the Deep Learning Accelerator that has been designed into its Xavier chip for AI-based autonomous vehicles.

In parallel with those efforts, Google has been using its TPUs for the inference stage of a deep neural network since 2015. TPUs are credited with helping to bolster the effectiveness of various AI workloads, including language translation and image recognition programs, the company said.

The combination of processing power, cloud access and machine-learning training models are combining to fuel Huang’s projected “Cambrian explosion” of AI technology: “Deep learning is a strategic imperative for every major tech company,” he observed. “It increasingly permeates every aspect of work from infrastructure, to tools, to how products are made.”

Free search engine tool hunts down malware-infected computers

By Fahmida Y. Rashid

Internet search engine Shodan provides enterprise security teams a wealth of information about open ports on servers and other internet-connected devices. Now, as part of a partnership with threat intelligence company Recorded Future, security analysts and researchers can work with Shodan to uncover systems manipulated to control malware-infected devices.

Shodan’s specialized crawler doesn’t gather information about websites, but rather details about the connected devices, including servers, routers, webcams, and other internet of things devices. The new Malware Hunter crawler takes the scanning a step further and actively hunts for computers that are acting as remote access Trojan (RAT) command-and-control servers. As such, it is a powerful tool for threat analysts, security operations center (SOC) teams, and dedicated security personnel within the enterprise trying to proactively identify and defend against certain types of malware families, said Levi Gundert, vice president of intelligence and strategy at Recorded Future.
