One Month to Cisco Live Las Vegas

We’re down to just a month before it’s time for Cisco Live in Las Vegas 2017. I’m really looking forward to meeting with a lot of people and attending some great sessions. This will also be my first event as a Cisco Netvet ? I have a few focus areas for this year’s event.

Cisco IWAN

I have a few IWAN projects I’m working on and I’m going to deep dive into IWAN during CLUS. My plans here are to attend the techtorial on Sunday and meet with some of the prominent people behind IWAN. Those contacts are invaluable to have when you are working on complex scenarios. I also want to see what’s on the roadmap and if I can find out anything about how the acquisition of Viptela will affect IWAN, if at all. I also want to see if APIC-EM has matured to be more useful in brownfield scenarios. Another interesting thing I will try to learn more about is how to best do monitoring in an IWAN network.

Cisco ACI

We have a lot of customers moving to ACI right now. Many of them have “legacy” data centers based on the Catalyst 6500. Moving to a vendor Continue reading

Container Deployment Demos from Interop ITX

At Interop ITX 2017 in Las Vegas, I had the privilege to lead a half-day workshop on options for deploying containers to cloud providers. As part of that workshop, I gave four live demos of using different deployment options. Those demos—along with the slides I used for my presentation along the way—are now available to anyone who might like to try them on their own.

The slides and all the resources for the demos are available in this GitHub repository. The four demos are:

  1. Docker Swarm on EC2: This demo leverages Terraform and Ansible to stand up and configure a Docker Swarm cluster on AWS.

  2. Amazon EC2 Container Service (ECS): This demo uses AWS CloudFormation to create an EC2 Container Service cluster with 3 instances and an Amazon RDS instance for backend database storage.

  3. Kubernetes on AWS using kops: Using the kops CLI tool, this demo turns up a Kubernetes cluster on AWS to show how to deploy containerized applications on Kubernetes.

  4. Google Container Engine: The final demo shows using Google Container Engine—which is Kubernetes—to deploy an application.

In the coming weeks, I plan to recreate the demos, record them, and publish them via YouTube, so that Continue reading

Gravityscan, keeping WordPress sites safe

If your website, in common with roughly 25% of all websites, is running WordPress then it's pretty much certain that it's being constantly attacked. WordPress is to hackers what raw meat is to jackals because unless sites are assiduously maintained, they quickly become vulnerable to a huge number of exploits.The root cause of this vulnerability is WordPress' ecosystem of complex core software augmented by thousands of third party developers whose themes and plugins are often buggy and not quickly (or often, never) updated to fend off known security problems. Add to that many site owners being slow to update their core WordPress installation and you have an enormous and easily discovered collection of irresistible hacking targets.To read this article in full, please click here

Worth Reading: Who pays security costs?

Computer security costs money. It costs more to develop secure software, and there’s an ongoing maintenance cost to patch the remaining holes. Spending more time and money up front will likely result in lesser maintenance costs going forward, but too few companies do that. Besides, even very secure operating systems like Windows 10 and iOS have had security problems and hence require patching. (I just installed iOS 10.3.2 on my phone. It fixed about two dozen security holes.) So — who pays? —CircleID

We have animatronic horror driven by Alexa, toy cars driven by deep learning, a couple of display projects, and cats recognized and monitored by Raspberry Pis. In short, more RPi goodness than you can shake a stick at.To read this article in full or to leave a comment, please click here

Spring Boot Development with Docker

The AtSea Shop is an example storefront application that can be deployed on different operating systems and can be customized to both your enterprise development and operational environments. In my last post, I discussed the architecture of the app. In this post, I will cover how to setup your development environment to debug the Java REST backend that runs in a container.

Building the REST Application

I used the Spring Boot framework to rapidly develop the REST backend that manages products, customers and orders tables used in the AtSea Shop. The application takes advantage of Spring Boot’s built-in application server, support for REST interfaces and ability to define multiple data sources. Because it was written in Java, it is agnostic to the base operating system and runs in either Windows or Linux containers. This allows developers to build against a heterogenous architecture.

Project setup

The AtSea project uses multi-stage builds, a new Docker feature, which allows me to use multiple images to build a single Docker image that includes all the components needed for the application. The multi-stage build uses a Maven container to build the the application jar file. The jar file is then copied to a Java Development Kit image. This Continue reading

iPhone 8 might be cheaper than we thought

Apple's upcoming iPhone 8 is going to be jam-packed with all sorts of advanced technologies and compelling new features. Of course, the most obvious change will be the iPhone 8's brand new form factor. Seeing as how the iPhone form factor hasn't really changed at all since the iPhone 6 and iPhone 6s Plus were released in 2014, the iPhone 8 will finally provide users with a fresh new design.Hardly a secret at this point, the iPhone 8 will feature an edgeless OLED display wherein the entire front face of the device will be the display. As for the home button and the Touch ID sensor, rumor has it that Apple has figured out a way to embed these into the display itself. The end result is that the iPhone 8 will essentially look like one giant piece of glass, which, interestingly enough, has long been Jony Ive's vision of an ideal iPhone design.To read this article in full or to leave a comment, please click here

Reflections on reflection (attacks)

Recently Akamai published an article about CLDAP reflection attacks. This got us thinking. We saw attacks from Conectionless LDAP servers back in November 2016 but totally ignored them because our systems were automatically dropping the attack traffic without any impact.

We decided to take a second look through our logs and share some statistics about reflection attacks we see regularly. In this blog post, I'll describe popular reflection attacks, explain how to defend against them and why Cloudflare and our customers are immune to most of them.

A recipe for reflection

Let's start with a brief reminder on how reflection attacks (often called "amplification attacks") work.

To bake a reflection attack, the villain needs four ingredients:

  • A server capable of performing IP address spoofing.
  • A protocol vulnerable to reflection/amplification. Any badly designed UDP-based request-response protocol will do.
  • A list of "reflectors": servers that support the vulnerable protocol.
  • A victim IP address.

The general idea:

  • The villain sends fake UDP requests.
  • The source IP address in these packets is spoofed: the attacker sticks the victim's IP address in the source IP address field, not their own IP address as they normally would.
  • Each packet Continue reading

Speed, Power, Performance: NSX & Memorial Day Motorsports

With Memorial Day weekend coming up, for me, it’s all about hot dogs, hamburgers, and fast car racing. I am huge Formula 1 fanatic, but Memorial Day is a bonanza of racing from the F1 Monaco Grand Prix, to NASCAR’s Coke 600, and of course the Indianapolis 500 all on the same day! The raw speed and performance of these races remind me of a 2016 VMworld presentation (NET8030) on NSX performance.

The argument still comes up now and again that “hardware is faster than software.” Network guys like me just assume that’s true. So, it came as a surprise to me when I watched the session which turned that assumption on its head. In this session, the presenter demonstrated that software is faster than hardware, way faster. Of course, I was dubious at first but quickly learned that physical networking and virtual networking is like the difference between the pace car and the race car. I always assumed the physical switch was the race car, but in the throughput presentation, Samuel showed two VM’s running on the same host with NSX routing, switching, and firewalling between them could get up to 106G! This information surprised me. Sort of like the same experience I had Continue reading
