A simple metadata server to run cloud images on standalone libvirt :: KVM Hypervisor

With all the interest in Cloud Computing and virtualization, the OS vendors are providing ever more easier ways to deploy VMs. Most of them now come with cloud images. This makes it really easy for users to deploy VMs with the distro of their choice on a cloud platform like OpenStack or AWS. Here are … Continue reading A simple metadata server to run cloud images on standalone libvirt :: KVM Hypervisor

Book – Unintended Features

Hi everyone,

I have some exciting news to share with you. I’ve been working on a book lately together with Russ White. It’s called Unintended Features – Thoughts on thinking and life as a network engineer. The book is partly based on blog post we have written in the past but also some unique content for the book. The outline of the book is as follows:

So you’ve decided you want to be a network engineer—or you’re already you a network engineer, and you want to be a better engineer, to rise to the top, to be among the best, to… Well, you get the idea. The question is, how do you get from where you are now to where you want to be? This short volume is designed to answer just that question.

This book tries to teach concepts not found in other writings such as thinking more about architecture and seeing patterns in technology and how to stay current in the networking industry. With the rapid pace of the networking industry it seems like we are sipping from the fire hose. How can we prevent this? Isn’t every new technology pretty much an old one with some new Continue reading

New Satana ransomware encrypts user files and master boot record

Attackers are developing an aggressive new ransomware program for Windows machines that encrypts user files as well as the computer's master boot record (MBR), leaving devices unable to load the OS.The program is dubbed Satana -- meaning "Satan" in Italian and Romanian -- and, according to researchers from security firm Malwarebytes, it is functional but still under development.Satana is the second ransomware threat affecting the MBR and seems inspired by another program, Petya, that appeared in March.To read this article in full or to leave a comment, please click here

Firmware exploit can defeat new Windows security features on Lenovo ThinkPads

A newly released exploit can disable the write protection of critical firmware areas in Lenovo ThinkPads and possibly laptops from other vendors as well. Many new Windows security features, like Secure Boot, Virtual Secure Mode and Credential Guard, depend on the low-level firmware being locked down.The exploit, dubbed ThinkPwn, was published earlier this week by a researcher named Dmytro Oleksiuk, who did not share it with Lenovo in advance. This makes it a zero-day exploit -- an exploit for which there is no patch available at the time of its disclosure.ThinkPwn targets a privilege escalation flaw in a Unified Extensible Firmware Interface (UEFI) driver, allowing an attacker to remove the flash write protection and to execute rogue code in the SMM (System Management Mode), a privileged operating mode of the CPU.To read this article in full or to leave a comment, please click here

Apple patents a smartphone camera kill switch

The advent of high-resolution video recording in smartphones has been a boon for fans looking for concert footage on YouTube, but the bands aren't so keen on their concerts appearing for free online before the show even ends.Of course, it also sucks to be at a concert and have your view blocked by the dozens of smartphones being held up to take pictures and video.So it seems Apple, which has been trying to cozy up to the music industry, has come up with a fix that sounds good on paper but has potential for misuse. It has been granted a patent, first filed in 2011 and refiled in 2014, that allows the iPhone camera to detect an infrared signal that will give instructions or information to the camera.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Cybersecurity: Stop the attacker’s offense, don’t do defense

Enterprises are fighting a cyber war against very sophisticated and highly organized adversaries. Yet companies still approach cybersecurity with a strictly defensive mindset. They operate under the belief that having the best defense will keep them safe from advanced adversaries. But attackers know how to break any defense, guaranteeing they’ll eventually infiltrate a company.Organizations need to approach security by thinking about how they can stop offense. How is this different from having a strong defense? When you’re stopping offense, you don’t stand on the sidelines waiting for an attacker to breach your network, hoping that the security measures you have in place will be enough to stop them.To read this article in full or to leave a comment, please click here

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
