Ansible 2.0 Has Arrived

Ansible-2-Release-Blog-Header

After a year of work, we are extremely proud to announce that Ansible 2.0 has been released and is now generally available. This is by far one of the most ambitious Ansible releases to date, and it reflects an enormous amount of work by the community, which continues to amaze me. Approximately 300 users have contributed code to what has been known as “v2” for some time, and 500 users have contributed code to modules since the last major Ansible release.

Why Did We Start V2?

There are many pitfalls to refactoring software, so why did we decide to tackle such a major project? At the time we started the work on v2, Ansible was approximately three years old and had recently crossed the 1,000 contributor mark. This huge rate in growth also resulted in a degree of technical debt in the code, which was beginning to show as we continued to add features.

Ultimately, we decided it was worth it to take a step back and rework some aspects of the codebase which had been prone to having features bolted on without a clear-cut architectural vision. We also rewrote from scratch much of the code which was responsible Continue reading

Have you broken your security resolutions yet?

Keeping your resolutionsImage by UsodesitaWe are almost halfway through the first month of 2016 and I am sure many people have already let their personal resolutions fall apart. But what about your professional resolutions? How have they held up? Is it easier to shore up your network’s security than exercise every day? These security professionals offer up their resolutions for the new year.To read this article in full or to leave a comment, please click here

Feds say only Chryslers were vulnerable to hacks via radio, not Audi or Volkswagen

U.S. auto safety regulators have determined that only infotainment centers from Fiat-Chrysler Automobiles (FCA) had a security flaw that could allow hackers to take control of Jeeps and several other model cars and trucks.Last summer, Fiat-Chrysler recalled 1.4 million Jeep, Chrysler, Dodge and Ram vehicles that had the security flaw.After a five-month investigation into cyberhacking vulnerabilities, the National Highway Traffic Safety Administration (NHTSA) said only FCA vehicles, and no others, were vulnerable to the hack.Affected were certain vehicles equipped with 8.4-in. Uconnect touchscreens: 2013-2015 Dodge Viper specialty vehicles 2013-2015 Ram 1500, 2500 and 3500 pickups 2013-2015 Ram 3500, 4500, 5500 Chassis Cabs 2014-2015 Jeep Grand Cherokee and Cherokee SUVs 2014-2015 Dodge Durango SUVs 2015 Chrysler 200, Chrysler 300 and Dodge Charger sedans 2015 Dodge Challenger sports coupes Audi Volkswagen and Bentley were also part of the NHTSA's investigation because they use the same infotainment center as Chrysler vehicles, which are made by Harman and used a similar Uconnect operating system.To read this article in full or to leave a comment, please click here

Microsemi builds better security into network time appliance

Keeping accurate time has never been more important. Inaccurate time can cause servers and applications to go awry, causing service disruptions.For example: As fighter Manny Pacquiao was ready to square off against Floyd Mayweather in May 2015, the fight was delayed due to a technical problem with pay-per-view orders. More than 4.4 million U.S. customers shelled out $100 to watch the fight but had trouble accessing it. The fight was delayed 45 minutes. It turns out the trouble was a problem with time. A time server was so far out of sync that people were disqualified from watching the fight because of a discrepancy with the time stamps.To read this article in full or to leave a comment, please click here

Rovnix malware shifts focus to Japan, says IBM

After a stint focusing on the Netherlands, a group using the Rovnix Trojan has updated it and repackaged it to steal from the bank accounts of victims in Japan, according to IBM X-Force.The malware in this exploit, which has persisted in various forms for about five years, has been augmented to avoid being detected, dodge bank security and convincingly mimic bank websites, says Etay Maor, a senior cybersecurity strategist for IBM.It’s pretty clear from the malware samples IBM X-Force has examined that the Rovnix group in question studied Japanese banks closely and came up with a user interface that closely mimics those of specific banking sites. It’s not just a generic key-logger that steals information and hopes for the best, Maor says.To read this article in full or to leave a comment, please click here

Are Unnumbered Interfaces Harmful?

A few weeks ago I got into an interesting discussion about the potential harm caused by unnumbered IPv4/IPv6 interfaces.

Ignoring for the moment the vendor-specific or media-specific implementation details, these two arguments usually pop up in the first 100 milliseconds (assuming engineers involved in the discussion have some hands-on operational experience):

Mozilla Persona login system to shut down end November

Mozilla's login system Persona will be shut down on Nov. 30 as its usage is low and has not grown over the last two years.The foundation's decision to take persona.org and related domains offline follows a move in March 2014 to transition the running of the project from full-time developers to a community of long-time volunteers and former paid contributors.Mozilla said at the time that it had no plans to decommission the little-known service, which allowed users to sign in to websites that support Persona using their verified email ids.  The key attraction of the service, according to Mozilla, was that users didn't have to trust a website with their password, preventing its theft if one of the websites got hacked.To read this article in full or to leave a comment, please click here

Powerball lessons for infosec

"Powerball" is a 44-state lottery whose prize now exceeds $1 billion, so there is much attention on it. I thought I'd draw some lessons for infosec.

The odds of a ticket winning the top prize is 1 in 292-million. However, last week 440-million tickets were purchased. Why did nobody win?

Because most people choose their own numbers. Humans choose numbers that are meaningful and lucky to them, such as birthdays, while avoiding meaningless or unlucky numbers, like 13. such numbers clump. Thus, while theory tells us there should've been at least one winner if everyone chose their number randomly, in practice a large percentage of possible numbers go unchosen. (Letting the computer choose random numbers doesn't increase your odds of winning, but does decrease the odds of having to sharing the prize).

The same applies to passwords. The reason we can crack passwords, even the tough ones using salted hashes, is because we rely upon the fact that humans choose passwords themselves. This makes password guessing a tractable human problem, rather than an intractable mathematical problem.

The average adult in lottery states spends $300 a year on the lottery. The amount spent on lotteries is more than sports, movies, music, Continue reading

Trend Micro flaw could have allowed attacker to steal all passwords

A discovery by a well-known Google security researcher provides further proof how antivirus programs designed to shield computers from attacks can sometimes provide a doorway for hackers. Tavis Ormandy, an information security engineer with Google, wrote he found bugs in Trend Micro's antivirus product that could allow remote code execution by any website and steal all of a users' passwords. The security firm has confirmed it has released an automatic update that fixes the problems. "As part of our standard vulnerability response process we worked with him to identify and address the vulnerability," wrote Christopher Budd, global threat communications manager at Trend Micro, in an email on Monday. "Customers are now getting protections through automatic updates."To read this article in full or to leave a comment, please click here

2015 in review and 2016 goals

Last year I started writing down my goals for each year.  My thought was that writing them down would be more meaningful than just thinking “I should try and do X this year”.  So I want to take a quick look at how I did and talk about 2016 as well. 

2015 Goals

Run a marathon
I signed up for, and attempted to run, the Twin Cities Marathon this fall.  I knew going into it that I wouldn’t run the whole thing.  My training schedule fell apart after the first month.  While I could list all of the reasons why (Our 2nd kid was on the way, work was crazy, etc) there really are no excuses.  In the month before the marathon I seriously picked up training again but it wasn’t enough.  My new goal became to run half which I was able to do and I considered it a huge win for me.  Having never run a race that big, I was a little hesitant about it but the experience was AWESOME and I’m definitely keeping this one on the goal list for 2016.

Should the US change metal coins?

It may be time for the United States to rethink how the smallest parts of its monetary system -- the penny, nickel and dime – are made.According to a report this week from watchdogs at the Government Accountability Office, since 2006 the prices of metals used in coins have risen so much that the total production unit costs of the penny and nickel exceed their face value resulting in financial losses to the U.S. Mint. In fact such a change could potentially save between $8 million and $39 million per year by changing the metal composition of the nickel, dime, and quarter.+More on Network World: 20 years ago: Hot sci/tech images from 1995+To read this article in full or to leave a comment, please click here
