Will AI usher in a new era of hacking?

It may take several years or even decades, but hackers won't necessarily always be human. Artificial intelligence -- a technology that also promises to revolutionize cybersecurity -- could one day become the go-to hacking tool.  Organizers of the Cyber Grand Challenge, a contest sponsored by the U.S. defense agency DARPA, gave a glimpse of the power of AI during their August event. Seven supercomputers battled each other to show that machines can indeed find and patch software vulnerabilities.Theoretically, the technology can be used to perfect any coding, ridding it of exploitable flaws. But what if that power was used for malicious purposes? The future of cyberdefense might also pave the way for a new era of hacking.To read this article in full or to leave a comment, please click here

Japan plans superefficient supercomputer by 2017

Japan plans to build a super-efficient computer that could vault it to the top of the world's supercomputer rankings by the end of next year.With a processing capacity of 130 petaflops, the planned computer would outperform the current world leader, China's Sunway TaihuLight, which delivers 93 petaflops. One petaflop is one million billion floating-point operations per second.Japan's National Institute of Advanced Industrial Science and Technology (AIST) isn't just aiming to build the world's fastest supercomputers, it also wants to make one of the most efficient. It is aiming for a power consumption of under 3 megawatts -- a staggering figure, given that Japan's current highest entry in the Top500 supercomputer list, Oakforest-PACS, delivers one-tenth the performance (13.6 petaflops) for the same power.To read this article in full or to leave a comment, please click here

Linux hardening: a 15-step checklist for a secure Linux server

Gus Khawaja Most people assume Linux is secure, and that’s a false assumption. Imagine your laptop is stolen without first being hardened. A thief would probably assume your username is “root” and your password is “toor” since that’s the default password on Kali and most people continue to use it. Do you? I hope not.The negative career implications of choosing not to harden your Kali Linux host are severe, so I’ll share the necessary steps to make your Linux host secure, including how I use penetration testing and Kali Linux to get the job done. It’s important to note that, while they are many distributions (AKA distros) of Linux and each one differs from the command line perspective, the logic is the same. Use the following tips to harden your own Linux box.To read this article in full or to leave a comment, please click here(Insider Story)

Installing Ansible 2.2 on Fedora 25

As part of my ongoing investigation of the usability of various Linux distributions and desktop environments, I’ve been working with Fedora 25. As part of the investigation I need to see how to perform certain tasks, one of which is working with Ansible. As a result, I needed to install Ansible 2.2 on Fedora 25, and it turns out it wasn’t as simple as pip install ansible.

I generally prefer to run Ansible in a Python virtualenv, but I don’t believe that it will make any difference to this procedure. However, I’m happy to be corrected if someone knows otherwise.

To create a Python virtualenv, you’ll first need virtualenv installed. I prefer to install virtualenv globally for all users using this command:

sudo -H pip install virtualenv

Once virtualenv is installed, then create a virtualenv for Ansible:

virtualenv ~/Envs ansible

Then activate the virtualenv:

source ~/Envs/ansible/bin/activate

At this point, you can try a pip install ansible, but it will fail. First, you need to install some additional development libraries that are required in order to install Ansible:

sudo dnf install libffi-devel redhat-rpm-config python-devel openssl-devel

Once those packages are installed, then you’re finally ready to install Ansible into Continue reading

Contrail Integration with Bare Metal Devices via EVPN-VxLAN

In this blog how we will discuss how to integrate Bare metal devices with Juniper Contrail (SDN Controller) by using EVPN-VXLAN.

My earlier blogs on Contrail can be viewed on links  Blog-1, Blog-2 ,

Reference Topology  

evpn-vxlan

Problem statement “Gust VM spawned inside SDN environment needs to communicate with Bare Metal Device (same sub net or different sub net here we will discuss former use case only).

Solution “EVPN based control plane will be established between MX Router and Contrail Controller to exchange ARP entries between them,  VxLAN based forwarding plane will be configured for communication between Guest VMs and Bare Metal Devices”

Solution components:-

  1. Contrail GUI
    • RED network 2.2.2.0/ is configured and VMs are spawned using open stack “Horizon” Web GUI (not covered in this article)
    • Configure VxLAN as 1st encapsulation method under “Encapsulation Priority Order” go to Configure then  Infrastructure  then Global Config and click edit button.
    • Select VxLAN Identifier Mode as “user configured”
    • Configure VxLAN ID & Route target community  for the desired network

Britain’s wartime codebreaking base could host a national cyber security college

Plans are afoot to build the U.K.'s first National College of Cyber Security at Bletchley Park, the birthplace of the country's wartime codebreaking efforts.It was at Bletchley Park that Colossus, the world's first electronic computer, was built during World War II to crack the Lorenz code used by the German high command. Bletchley is also where Alan Turing developed some of his mathematical theories of computing while working on breaking the enigma code.After the war the site fell into disrepair, but parts of it have been restored and now house the U.K.'s National Museum of Computing.To read this article in full or to leave a comment, please click here

10 smartphone trends to watch in 2017

Smartphone buyers have a lot to look forward to in 2017. Devices will be thinner, faster, and perhaps a bit more intelligent than you'd like. Virtual reality will spread to budget smartphones, and they will also have better graphics, higher resolution screens, and more storage. More than ever, you'll be using your smartphone to pay for products and log into websites. Deep learning could help smartphones get a fix on user behavior and improve the mobile experience. We could see a renaissance in smartphone designs, and wireless audio could replace headphone jacks in more handsets. USB-C will replace older connector and charging cables. Here are 10 smartphone trends to watch out for in 2017:To read this article in full or to leave a comment, please click here

FPGAs Give Microsoft a “Von Neumann Tax” Break

At the annual Supercomputing Conference (SC16) last week, the emphasis was on deep learning and its future role as part of supercomputing applications and systems. Before that focus, however, the rise of novel architectures and reconfigurable accelerators (as alternatives to building a custom ASIC) was swift.

Feeding on that trend, a panel exploring how non-Von Neumann architectures looked at the different ways the high performance computing set might consider non-stored program machines and what the many burgeoning options might mean for energy efficiency and performance.

Among the presenters was Gagan Gupta, a computer architect with Microsoft Research, who detailed the …
