Infosys to acquire startup Panaya to automate customer tasks

Indian outsourcer Infosys is to acquire Panaya, a U.S. vendor of automation technology for testing enterprise software deployments and upgrades.The cash deal values Panaya at an enterprise value of US$200 million, and is in line with the company’s strategy under new CEO Vishal Sikka to automate processes, including by using artificial intelligence, to cut down on repetitive tasks and accelerate services delivery.“This acquisition aims to use automation to boost the revenue of the company without a corresponding increase in staff,” said Sudin Apte, CEO and research director at analyst firm Offshore Insights. He pointed out that Infosys’ rivals like Tata Consultancy Services already use some degree of automation developed in-house.To read this article in full or to leave a comment, please click here

Cybercriminal gang plunders up to $1 billion from banks over two years

A still-active cybercriminal gang has stolen up to a $1 billion from banks in at least 25 countries over the last two years, infiltrating networks with malware and spying on employees’ computers to facilitate large wire transfers, Kaspersky Lab said Sunday.The computer security vendor, which said it will release a report Monday on its findings, said the gang penetrated deeply into the banks’ networks, taking time to learn about internal procedures to make their fraudulent activity less suspicious.In some cases, the gang learned about wire transfer systems by watching administrators’ computers over video.“In this way the cybercriminals got to know every last detail of the bank clerks’ work and were able to mimic staff activity in order to transfer money and cash out,” Kaspersky said in a news release.To read this article in full or to leave a comment, please click here

Generating Web Docs for Ansible Modules

If you have ever worked with Ansible, it’s almost a guarantee that you have used their online docs to figure out what parameters a given module supports, how they should be used, or what their defaults are. Over the past few weeks, I’ve been working on a few custom modules and was trying to find a way to generate web docs for them, and have them locally accessible or easily posted to GitHub.

Ansible offers a way to “make webdocs,” but it generates the complete module inventory and truth be told, I didn’t get this work for my custom modules, so I figured I would explore a “simplified” way — a way that should be able to generate docs as needed for one or more modules on an as needed basis.

The outcome was the creation of an Ansible module and Jinja2 template that automatically generates a markdown file (that can then be viewed or posted anywhere).

How does it work?

The modules you’ve built or are local to your machine (even Ansible core modules) that you want to generate a web doc for must be documented according to Ansible standards. That’s the only major requirement.

From there, Continue reading

NAT, Security, and Repeating Myself

In a former post I pointed out that we need to think of obscurity as a tool in network security — that we shouldn’t try to apply rules that are perfectly logical in terms of algorithms to networks as a system. While I’m not normally one to repeat myself, this topic needs a little more […]

Securing BFD now possible!

Confession Time.

I am guilty of committing several sins. One that egregiously stands out is writing two IETF specs for BFD security (here and here) without considering the impact on the routers and switches implementing those specs. Bear in mind that Bi-directional Forwarding Detection (BFD) is a hard protocol to implement well. Its hard to get into a conversation with engineers working on BFD without a few of them shedding copious quantities of tears on what it took them to avoid those dreaded BFD flaps in scaled setups. They will tell you how they resorted to clever tricks (hacks, if you will) to process BFD packets as fast as they could (plucking them out of order from a shared queue, dedicated tasks picking up BFD packets in the ISR contexts, etc) . In a candid conversation, an ex-employee of a reputed vendor revealed how they stage managed their BFD during a demo to a major customer since they didnt want their BFD to flap while the show (completely scripted) was on. So, long story short — BFD is hard when you start scaling. It just becomes a LOT worse, when you add security on top of it.

The reason BFD is hard is because of Continue reading

Exporting NetFlow from Linux to a collector over IPv6

There is another project out there in the ether that I have a hand in providing input for. One of the features that I felt was necessary for it is exporting NetFlow information from traffic the Linux machine handled, to a collector. This is dual-stack traffic, but I have the collector listening on IPv6.

Firstly, I needed something that would gather and export the data, so I found softflowd. My ubuntu server had it in the repo, so a quick apt install got it onto the machine easily enough. You need to edit /etc/default/softflowd and set what interface(s) you want it capturing & generating flow data from, and what options to feed to the daemon, like what server:port to export that data to:

INTERFACE="eth#"
OPTIONS="-v 9 -n [x:x:x:x::x]:9995"

Fill in the correct interface name you want to gather data from. The -v 9 option tells it to use Netflow v9, which has IPv6 support The -n option is used for specifying the collector machine’s IP and port, and fill in for the correct IPv6 address of that collector. Above is the format for specifying an IPv6 host running a collector, like nfcapd. Then you can fire up the softflowd daemon, Continue reading

CLUS Keynote Speaker – It’s a Dirty Job but Somebody’s Gotta Do It

Did you guess by the title who will be the celebrity keynote speaker for CLUS San Diego? It’s none other than Mike Rowe, also known as the dirtiest man on TV.

Mike is the man behind “Dirty Jobs” on the Discovery Channel. Little did he know when pitching the idea to Discovery that they would order 39 episodes of it. Mike traveled through 50 states and completed 300 different jobs going through swamps, sewers, oil derricks, lumberjack camps and what not.

Mike is also a narrator and can be heard in “American Chopper”, “American Hot Rod”, “Deadliest Catch”, “How the Universe Works” and other TV shows.

He is also a public speaker and often hired by Fortune 500 companies to tell their employees frightening stories of maggot farmers and sheep castrators.

Mike also believes in skilled trades and in working smart AND hard. He has written extensively on the country’s relationship with work and the skill gap.

I’m sure Mike’s speach will be very interesting…and maybe a bit gross…

Install the CORE Network Emulator on Amazon AWS

Having set up an Ubuntu Linux server running on a free micro-instance in Amazon’s Web Services EC2 service, I’d like to see how some of the open-source network simulation tools I’ve been using work in the cloud.

First, I will install the CORE Network Emulator on my Amazon AWS EC2 virtual private server. Please read the rest of this post to see how it works.

I expect that the CORE Network Emulator will install and run on an Amazon EC2 instance because it uses Linux Containers (LXC) as its virtualization technology. I have already observed that LXC containers work when run inside a virtual machine on my Laptop computer. It should work the same when running in a virtual machine in Amazon’s EC2 cloud computing service.

Install CORE

I’ve already described how to install the CORE network emulator in previous posts so I will list the installation steps below without any explanation. For details, please see my post on how to install the CORE Network Emulator from source code.

Install prerequisite software

$ sudo apt-get update
$ sudo apt-get install bash bridge-utils ebtables 
  iproute libev-dev python tcl8.5 tk8.5 libtk-img 
  autoconf automake gcc libev-dev make python-dev

Vint Cerf worries about a ‘digital dark age,’ and your data could be at risk

In this era of the all-pervasive cloud, it’s easy to assume that the data we store will somehow be preserved forever. The only thing to fret about from a posterity perspective, we might think, is the analog information from days gone by—all the stuff on papers, tapes and other pre-digital formats that haven’t been explicitly converted.Vinton Cerf, often called “the father of the Internet,” has other ideas.Now chief Internet evangelist at Google, Cerf spoke this week at the annual meeting of the American Association for the Advancement of Science, and he painted a very different picture.Rather than a world where longevity is a given, Cerf fears a “digital dark age” in which the rapid evolution of technology quickly makes storage formats obsolete thanks to a phenomenon he calls “bit rot.”To read this article in full or to leave a comment, please click here
