Open vSwitch Day at OpenStack Summit 2017
This is a “liveblog” (not quite live, but you get the idea) of the Open vSwitch Open Source Day happening at the OpenStack Summit in Boston. Summaries of each of the presentations are included below.
Kubernetes and OVN on Windows
The first session was led by Cloudbase Solutions, a company out of Italy that has been heavily involved in porting OVS to Windows with Hyper-V. The first part of the session focused on bringing attendees up to speed on the current state of OVS and OVN on Hyper-V. Feature parity and user interface parity between OVS/OVN on Hyper-V is really close to OVS/OVN on Linux, which should make it easier for Linux sysadmins to use OVS/OVN on Hyper-V as well.
The second part of the session showed using OVN under Kubernetes to provide networking between Windows containers on Windows hosts and Linux containers on Linux hosts, including networking across multiple cloud providers.
Lightning Talks
The lightning talks were all under 5 minutes, so a brief summary of these are provided below:
- Joe Stringer showed how to set up OVS with an OpenFlow controller (Faucet) to do networking between multiple hosts in 5 minutes or less.
- A gentleman (I didn’t catch Continue reading

Docker Enterprise Edition Brings New Life Back to Legacy Apps at Northern Trust
Many organizations understand the value of building modern 12-factor applications with microservices. However, 90+% of applications running today are still traditional, monolithic apps. That is also the case for Northern Trust – a 128-year old financial services company headquartered in Chicago, Illinois. At DockerCon 2017, Rob Tanner, Division Manager for Enterprise Middleware at Northern Trust, shared how they are using Docker Enterprise Edition (EE) to modernize their traditional applications to make them faster, safer, and more performant.
Bringing Agility and Security to Traditional Apps
Founded in 1889, Northern Trust is a global leader in asset servicing, asset management, and banking for personal and institutional clients. Their clients expect best-of-breed services and experiences from Northern Trust and Rob’s team plays a large role in delivering that. While their development teams are focused on microservices apps for greenfield projects, Rob is responsible for over 400 existing WebLogic, Tomcat, and .NET applications. Docker EE became the obvious choice to modernize these traditional apps and manage their incredibly diverse environment with a single solution.
Containerizing traditional applications with Docker EE gives Northern Trust a better way to manage them and some immediate benefits:
- Improved security: As a financial institution, security is a top priority. Continue reading
Hacker dumps, magnet links, and you
In an excellent post pointing out Wikileaks deserves none of the credit given them in the #MacronLeaks, the author erroneously stated that after Archive.org took down the files, that Wikileaks provided links to a second archive. This is not true. Instead, Wikileaks simply pointed to what's known as "magnet links" of the first archive. Understanding magnet links is critical to understanding all these links and dumps, so I thought I'd describe them.The tl;dr version is this: anything published via BitTorrent has a matching "magnet link" address, and the contents can still be reached via magnet links when the original publisher goes away.
In this case, the leaker uploaded to "archive.org", a popular Internet archiving resource. This website allows you to either download files directly, which is slow, or via peer-to-peer using BitTorrent, which is fast. As you know, BitTorrent works by all the downloaders exchanging pieces with each other, rather getting them from the server. I give you a piece you don't have, in exchange for a piece I don't have.
BitTorrent, though still requires a "torrent" (a ~30k file that lists all the pieces) and a "tracker" (http://bt1.archive.org:6969/announce) that keeps a list Continue reading
Some notes on #MacronLeak
Are they Macron's emails?
No. They are e-mails from members of his staff/supporters, namely Alain Tourret, Pierre Person, Cedric O??, Anne-Christine Lang, and Quentin Lafay.
There are some documents labeled "Macron" which may have been taken from his computer, cloud drive -- his own, or an assistant.
Who done it?
Obviously, everyone assumes that Russian hackers did it, but there's nothing (so far) that points to anybody in particular.
It appears to be the most basic of phishing attacks, which means anyone could've done it, including your neighbor's pimply faced teenager.
Update: Several people [*] have pointed out Trend Micro reporting that Russian/APT28 hackers were targeting Macron back on April 24. Coincidentally, this is also the latest that emails appear in the dump.

What's the hacker's evil plan?
Everyone is proposing theories about the hacker's plan, but the most likely answer is they don't have one. Hacking is opportunistic. They likely targeted everyone in the campaign, and these were the Continue reading
Technology Short Take #82
Welcome to Technology Short Take #82! This issue is a bit behind schedule; I’ve been pretty heads-down on some projects. That work will come to fruition in a couple weeks, so I should be able to come up for some air soon. In the meantime, here’s a few links and articles for your reading pleasure.
Networking
- Kristian Larsson shows how to validate data using YANG. Practical examples like this have really helped me better understand YANG and its relationship to structured data you might exchange with a device or service.
- There’s lots of talk about applying test-driven development (TDD) principles in various automation contexts, but I like the fact that Ajay Chenampara provides some practical examples in his blog post on applying TDD in network automation using Ansible.
- Matt Oswalt talks about how the combination of NAPALM and StackStorm enables some interesting results, including the ability to verify configuration consistency. StackStorm isn’t something I’ve had the opportunity to learn/use at all, but it’s on my (ever-growing) list of things to check out.
- Aaron Conole provides an overview of using the
ovs-dpctlcommand to “program” the Open vSwitch (OVS) kernel module. It’s a bit geeky, but does provide some insight into Continue reading
FBI’s Comey dangerous definition of “valid” journalism
The First Amendment, the "freedom of speech" one, does not mention journalists. When it says "freedom of the press" it means the physical printing press. Yes, that does include newspapers, but it also includes anybody else publishing things, such as the famous agitprop pamphlets published by James Otis, John Dickinson, and Thomas Paine. There was no journalistic value to Thomas Paine's Common Sense. The pamphlet argued for abolishing the monarchy and for American independence.Today in testimony before congress, FBI directory James Comey came out in support of journalism, pointing out that they would not prosecute journalists doing their jobs. But he then modified his statement, describing "valid" journalists as those who in possession of leaks would first check with the government, to avoid publishing anything that would damage national security. It's a power the government has abused in the past to delay or censor leaks. It's specifically why Edward Snowden contacted Glenn Greenwald and Laura Poitras -- he wanted journalists who would not kowtow the government on publishing the leaks.
Comey's testimony today was in regards to prosecuting Assange and Wikileaks. Under the FBI's official "journalist" classification scheme, Wikileaks are not real journalists, but instead publish "intelligence porn" and Continue reading
Juniper Control Plane Protection
How Does Internet Work - We know what is networking
I already wrote about Control Plane Protection in one of my previous posts focused on Cisco device configuration. Here we will make the same thing on Juniper device, I was using Juniper SRX300 and Juniper SRX1500 devices in my lab. CoPP ?? Control Plane Protection (CoPP) is a method of protecting processor unit, running services on your network device, against excessive flooding. Excessive flooding of traffic aimed towards your router/firewall processor, being that valid or malicious, is always undesirable and can also be dangerous. A network device, which starts the receive more control traffic that his processor can process, will

The Myth of Pure Cloud
Despite the movement to cloud, data centers will still be around for the foreseeable future.
Introducing TLS with Client Authentication
In a traditional TLS handshake, the client authenticates the server, and the server doesn’t know too much about the client. However, starting now, Cloudflare is offering enterprise customers TLS with client authentication, meaning that the server additionally authenticates that the client connecting to it is authorized to connect.
TLS Client Authentication is useful in cases where a server is keeping track of hundreds of thousands or millions of clients, as in IoT, or in a mobile app with millions of installs exchanging secure information. For example, an IoT company can issue a unique client certificate per device, and then limit connections to their IoT infrastructure to only their devices by blocking connections where the client doesn’t present a certificate signed by the company’s certificate authority.
Or in the case of a mobile banking app, where the bank wants to ensure customers’ secure financial data doesn’t get stolen by bots spoofing their mobile app, they can issue a unique certificate to every app install and in the TLS handshake validate requests are coming from their mobile app. Client authentication is also useful for VPNs, enterprise networks or staging sites, where corporations and developers need to lock down connections to only laptops Continue reading

vRealize Network Insight, NSX and Palo Alto Networks for micro-segmentation
Data Center cyber security is a fast-moving target where the IT teams need to constantly stay ahead of those that wish to do evil things. As security attacks can come from all directions, externally, and internally as well, the IT teams must fortify all the data, with a zero-trust security approach. Perimeter security augmented with intrusion detection and protection at the application level are the tools of choice for most data centers. This protects outsiders from getting in, as well as ensuring that the applications do not get impacted by a virus or other forms of malicious activities.
What has not been addressed is the intercommunications of applications amongst themselves, especially within the hypervisor layer, where virtual machines are communicating in an East-West traffic pattern. Traffic never hits the perimeter, and the conversations are happening several layers below the application layers where IDS sits. East-west traffic, from within the data center, has been an area overlooked as there is a gap organizationally. Simply put no one is paying attention to this area of vulnerability. The network infrastructure security teams are fortifying the perimeter, while the server teams are deploying IDS/IPS solutions. What has gone unnoticed is the East-West Continue reading

“Fast and Furious 8: Fate of the Furious”
So "Fast and Furious 8" opened this weekend to world-wide box office totals of $500,000,000. I thought I'd write up some notes on the "hacking" in it. The tl;dr version is this: yes, while the hacking is a bit far fetched, it's actually more realistic than the car chase scenes, such as winning a race with the engine on fire while in reverse.[SPOILERS]
Car hacking
How real is this?
Well, today, few cars have a mechanical link between the computer and the steering wheel. No amount of hacking will fix the fact that this component is missing.
With that said, most new cars have features that make hacking possible. I'm not sure, but I'd guess more than half of new cars have internet connections (via the mobile phone network), cameras (for backing up, but also looking forward for lane departure warnings), braking (for emergencies), and acceleration.

Twistlock Closes $17M Funding Round for Container Security

AES-CBC is going the way of the dodo
A little over a year ago, Nick Sullivan talked about the beginning of the end for AES-CBC cipher suites, following a plethora of attacks on this cipher mode.
Today we can safely confirm that this prediction is coming true, as for the first time ever the share of AES-CBC cipher suites on Cloudflare’s edge network dropped below that of ChaCha20-Poly1305 suites, and is fast approaching the 10% mark.
Over the course of the last six months, AES-CBC shed more than 33% of its “market” share, dropping from 20% to just 13.4%.
All of that share, went to AES-GCM, that currently encrypts over 71.2% of all connections. ChaCha20-Poly1305 is stable, with 15.3% of all connections opting for that cipher. Surprisingly 3DES is still around, with 0.1% of the connections.
The internal AES-CBC cipher suite breakdown as follows:
The majority of AES-CBC connections use ECDHE-RSA or RSA key exchange, and not ECDHE-ECDSA, which implies that we mostly deal with older clients.
RSA is also dying
In other good new, the use of ECDSA surpassed that of RSA at the beginning of the year. Currently more than 60% of all connections use Continue reading
