Top Docker content of 2016

2016 has been an amazing year for Docker and the container industry. We had 3 major releases of Docker engine this year , and tremendous increase in usage. The community has been following along and contributing amazing Docker resources to help you learn and get hands-on experience. Here’s some of the top read and viewed content for the year:

Releases

Of course releases are always really popular, particularly when they fit requests we had from the community. In particular, we had:

  • Docker for Mac & Docker for Windows Beta and GA release blog posts, and the video

Windows Containers

When Microsoft made Windows 2016 generally available, people rushed to

Docker resources for Microsoft

About Docker

We also provide a lot of information about how to use Docker. In particular, these posts and articles that we shared on social media were the most read:

brvirt: when brctl meets virsh

Hypervisors diversity is definitely one of the benefits of having Nuage managing your next-generation network. That means that we, as Nuage engineers, have to play with all kinds of hypervisors — like KVM, ESXi and Hyper-V to be more precise. As to me, I love to work with KVM most, simply because it gives you that feel that you

IDG Contributor Network: More file sync and sharing industry FUD

I received a pitch the other day from a vendor in the enterprise file sharing and synchronization (EFSS) space. I won't name the company. I probably should, to really show my scorn, but I'll deny them the Google juice instead.Anyway, the pitch told me about how said vendor made a "startling discovery" as it was planning a routine Google Adwords Campaign. It seemed that searches inadvertently turned up sensitive and confidential materials.Said vendor apparently disclosed the finding to the two other EFSS vendors, who indicated they would address the "security flaw." Now, some three years later, the same thing is happening.To read this article in full or to leave a comment, please click here

APIC-EM Path Trace Examples – Overlay Networks

Since seeing the APIC-EM Path Trace demo for the first time and seeing how it represents CAPWAP, I’ve been curious how well it deals with other types of overlay/underlay networking. This article is a brief synopsis of that testing and provides some visuals around what was produced with this free management tool.

TL;DR–APIC-EM adds value to most network path traces and typically represents what it knows. The single exception is with MPLS VPNv4. If the MPLS PE nodes are pulled into the device inventory, path trace has a total lack of understanding around the recursive lookup into the global vrf that is required for VPNv4 functionality.

CAPWAP Representation — The Gold Standard

I wanted to start out by showing what an ideal representation of an overlay network would be for a tool like this. Path Trace understands AND clearly represents both the underlay and the overlay network for traffic flowing through a CAPWAP tunnel. The image below shows the extent of the tunnel (darker gray) and the physical components that are responsible for delivery (both through the tunnel and outside of the tunnel).

Testing Topology

For the additional testing, I built the following topology and integrated APIC-EM into my Continue reading

5 signs we’re finally getting our act together on security

The high-water line in information security gets higher each year. Just as we think we’ve finally figured out how to defend against attacks, then attackers come up with something new and we are right back to trying to figure out what to do next.For example, ransomware has surged in the last year. Although that kind of malware has been around for years, the current model of encrypting user files to hold data hostage came about just recently. Infections quadrupled in 2016, with the FBI estimating an average of 4,000 attacks a day. A recent IBM survey of 600 business leaders in the United States found that one in two had experienced a ransomware attack in the workplace, and that companies paid the ransom 70 percent of the time. As a result, criminals are on track to make nearly $1 billion this year from ransomware, IBM X-Force said.To read this article in full or to leave a comment, please click here

Apple’s 10 biggest wins, fails, and WTF moments of 2016

Apple has been doomed for decades, if the steady stream of headlines about the company, its stock price, and its product lineup are to be believed. If The Macalope has taught us anything, it's that the Apple deathwatch business is a brisk (and bizarre) one. The truth is much more complex. But by any measure, 2016 was a particularly tough year for Apple.The company endured a bitter legal fight with the FBI, saw its first revenue decline in more than a decade, and faced backlash over hardware tweaks in its upgraded flagship products: the iPhone 7’s lack of a 3.5mm audio jack and the overhauled MacBook Pro’s less-than-pro specs for a decidedly pro price.To read this article in full or to leave a comment, please click here

What to do if your data is taken hostage

Getting duped online by a cybercriminal is infuriating. You let your guard down for a minute and the thieves find their way in to your machine.And then the “fun” begins if ransomware is involved. Hopefully you have your data backed up, but if not now starts the dance with those who have ultimately taken you hostage. Ransomware is obviously analogous to kidnapping, and dealing with the perpetrators can feel much like negotiating with a jumper standing on the edge of high-rise roof.Look no further for help than the Institute for Critical Infrastructure Technology report that in part describes how to deal with criminals when they are holding your data hostage. The report talks of what to do once a breach has been found.To read this article in full or to leave a comment, please click here

Source-Specific Multicast Configuration

How Does Internet Work - We know what is networking

In SSM, Source-Specific Multicast, things are done differently from standard multicast forwarding. SSM is specifying a group of hosts that are receiving same multicast stream using group IP address and additionally using stream unicast source IP. In this article it is shown how to configure Source Specific Multicast on Cisco and Juniper equipment. In standard multicast, forwarding is done using group IP address which is an IP from multicast dedicated range 224.0.0.0/4 (224.0.0.0 – 239.255.255.255) or FF00::/8 in IPv6. Each multicast group IP address is a single address which specifies all hosts receiving a specific stream, streamed towards that group

OpenBSD on the Sixth Generation Intel NUC

Sixth Generation Intel NUC

I recently decided it would be fun to upgrade the hardware on my main OpenBSD machine at home (because, you know, geek). These Intel NUC machines are pretty interesting. They are pretty powerful, support a decent amount of RAM, certain models support internal storage, and they are very low power and low noise. Perfect for a machine that is a shell/email/development box.

IoT saves lives but infosec wants to change that

The cybersecurity industry mocks/criticizes IoT. That's because they are evil and wrong. IoT saves lives. This was demonstrated a couple weeks ago when a terrorist attempted to drive a truck through a Christmas market in German. The truck has an Internet-connected braking system. When it detected the collision, it deployed the brakes, bringing the truck to a stop. Injuries and deaths were a 10th of the similar Nice truck attack earlier in the year.

All the trucks shipped by Scania in the last five years have had mobile phone connectivity to the Internet. Scania pulls back telemetry from trucks, for the purposes of improving drivers, but also to help improve the computerized features of the trucks. They put everything under the microscope, such as how to improve air conditioning to make the trucks more environmentally friendly.

Among their features is the "Autonomous Emergency Braking" system. This is the system that saved lives in Germany.

You can read up on these features on their website, or in their annual report [*].


My point is this: the cybersecurity industry is a bunch of police-state fetishists that want to stop innovation, to solve the "security" problem first before allowing innovation Continue reading
