Use Apache Spark? This tool can help you tap machine learning

Finding insight in oceans of data is one of enterprises' most pressing challenges, and increasingly AI is being brought in to help. Now, a new tool for Apache Spark aims to put machine learning within closer reach.Announced on Friday, Sparkling Water 2.0 is a major new update from H2O.ai that's designed to make it easier for companies using Spark to bring machine-learning algorithms into their analyses. It's essentially an API (application programming interface) that lets Spark users tap H2O's open-source artificial-intelligence platform instead of -- or alongside -- the algorithms included in Spark's own MLlib machine-learning library.To read this article in full or to leave a comment, please click here

Cato Networks offers a new model for network security as a service  

This column is available in a weekly newsletter called IT Best Practices.  Click here to subscribe.   The advent of worker mobility and cloud computing have played havoc with the traditional network perimeter. At one time the perimeter was a well-established concept. All of our users, locations, data centers and applications were inside this zone protected by strong network security. That notion seems almost quaint today. With mobile users and data and applications in the cloud, the old perimeter has basically dissolved, leading to the development of entirely new security tools—secure web gateways, cloud access security brokers, enterprise mobility management, and so on. These new products and services augment the traditional network security stack of firewalls, anti-virus, email and web filtering, etc.To read this article in full or to leave a comment, please click here

DARPA unified space-sensor networks help keep orbiting junk from slamming into something important

DARPA recently said that it had finished integrating seven space-watching networks that will feed tons of new Earth-orbiting junk data into what the agency calls “the largest and most diverse network of space situational awareness networks ever assembled.”+More on Network World: NASA’s hot Juno Jupiter mission+DARPA’s OrbitOutlook (O2) program brings seven previously separate new space sensor networks together that could ultimately feed into the United States Space Surveillance Network (SSN), a worldwide network of 29 military radar and optical telescopes operated by the Air Force as well as NASA, the FAA and other entities that could use the information.To read this article in full or to leave a comment, please click here

Worth Reading: Open season

Let’s once more look at this topic again, and start with what we mean by the term “Open Internet.” The expression builds upon a rich pedigree of the term “open” in various contexts. It gives the impression that “open” is some positive attribute, and when we use the expression of the “open Internet”, it seems that we’re lauding it in some way. But are we, and if so, in what way? -CircleID

Big Brother is listening as well as watching

In a world of ubiquitous security cameras, most people know by now that some form of Big Brother – government or private – is watching them. But they are less likely to know that in some areas, he is also listening.While it is not yet widespread, audio surveillance is increasingly being used on parts of urban mass transit systems.That is the bad news, in the view of privacy advocates. But the good news is that public awareness can, at least in some cases, curtail it.This past week, following revelations that New Jersey Transit didn’t have policies governing storage and who had access to data from audio surveillance on some of its light-rail trains, the agency ended the program.To read this article in full or to leave a comment, please click here

Real-time BGP route analytics

The diagram shows how sFlow-RT real-time analytics software can combine BGP route information and sFlow telemetry to generate route analytics. Merging sFlow traffic with BGP route data significantly enhances both data streams:
  1. sFlow real-time traffic data identifies active BGP routes
  2. BGP path attributes are available in flow definitions
The following example demonstrates how to configure sFlow / BGP route analytics. In this example, the switch IP address is 10.0.0.253, the router IP address is 10.0.0.254, and the sFlow-RT address is 10.0.0.162.

Setup

First download sFlow-RT. Next create a configuration file, bgp.js, in the sFlow-RT home directory with the following contents:
var reflectorIP  = '10.0.0.254';
var myAS         = '65162';
var myID         = '10.0.0.162';
var sFlowAgentIP = '10.0.0.253';

// allow BGP connection from reflectorIP
bgpAddNeighbor(reflectorIP,myAS,myID);

// direct sFlow from sFlowAgentIP to reflectorIP routing table
// calculate a 60 second moving average byte rate for each route
bgpAddSource(sFlowAgentIP,reflectorIP,60,'bytes');
The following sFlow-RT System Properties load the configuration file and enable BGP:
  • script.file=bgp.js
  • bgp.start=yes
Start sFlow-RT and the following log lines will confirm that BGP has been enabled and configured:

Hackers are coming for your healthcare records — here’s why

Data stolen from a bank quickly becomes useless once the breach is discovered and passcodes are changed. But data from the healthcare industry, which includes both personal identities and medical histories, can live a lifetime.Cyberattacks will cost hospitals more than $305 billion over the next five years and one in 13 patients will have their data compromised by a hack, according to industry consultancy Accenture. Accenture And a study by the Brookings Institution predicts that one in four data breaches this year will hit the healthcare industry.To read this article in full or to leave a comment, please click here

Jeremiah Grossman: Focus on ransomware, SDLC, and endpoints

With so many elements in information security -- application, network infrastructure, the endpoint, perimeter defenses, and data-centric approaches -- it's easy to fall in the trap of touting one as more important than the other. But it's a mistake to consider information security as a series of silos when it's actually an intersection of different areas. That overlap is most evident with application and endpoint security.For Jeremiah Grossman, the new chief security strategist at security vendor Sentinel One, application security and endpoint security are just different steps in the kill chain. As the founder and former CTO of the consultancy WhiteHat Security, Grossman has been the go-to-expert for web application security for years, and his new focus on endpoint security at Sentinel One does not mean that he has given up on securing web applications.To read this article in full or to leave a comment, please click here
