It’s been a bit of a crazy week — out to SFO, where I saw a lot of old friends, for NANOG. I picked up the top shirt on my pile this morning, and discovered it’s an old NANOG shirt, SFO in 2004 (!). The good news is the NANOG folks get their videos on line really fast — and all of them are worth watching. The channel is here, but I’d like to especially point out the talks on active monitoring, QUIC, and OpenConnect. Yes, my presentation is there, too.

One point to remember is that as the “network guy,” you stand between people and their funny cat videos. While people get mad about plumbing, they seem to get irate about their network access — because it’s all virtual it all seems so easy, I guess. It doesn’t help that the modern face of IT tends to be large companies that have a virtual monopoly and totally horrible customer service. But whatever the reason, it means you have to be extra careful not to step on people’s toes when you’re doing network engineering — the perception doesn’t have to be reality to impact your life.

Records on 4 million people stolen in huge government data breachIn what may be one of the biggest data breaches ever affecting the U.S. government, hackers broke into the systems of the Office of Personnel Management and the records of approximately four million people have been stolen. Investigators suspect hackers based in China and have linked this latest intrusion to earlier hacks into health insurers Anthem and Wellspring, the New York Times reports. An executive of security firm iSight told the Times that researchers believe the hacking group is creating a huge database of personally identifiable information “that they can reach back to for further activity.”To read this article in full or to leave a comment, please click here

Video: Scale-Out NAT

Network Address Translation (NAT) is one of those stateful services that’s almost impossible to scale out, because you have to distribute the state of the service (NAT mappings) across all potential ingress and egress points.

Midokura implemented distributed stateful services architecture in their Midonet product, but faced severe scalability challenges, which they claim to have solved with more intelligent state distribution.

Acer says Predator 8 gaming tablet primed for September launch

Acer couldn’t keep the mystery around the launch of its highly-anticipated Acer Predator 8-inch gaming tablet bottled up for too long.The tablet could launch sometime in September, with a big event planned for Europe, said a representative at the Acer booth on the Computex show floor this week.The tablet was first shown on stage in April at a lavish event at the World Trade Center in New York. At the time, Acer CEO Jason Chen said during an interview that the tablet details were being finalized and more details would be shared at launch. However, no specific launch date was provided.But details about the tablet starting trickling out much earlier at Computex in Taipei this week. It will run on Android OS and have Intel’s Atom processor code-named Cherry Trail, which has two times faster graphics than the aging predecessor chip code-named Bay Trail. The Cherry Trail chip is also used in Microsoft’s Surface 3, which started shipping last month.To read this article in full or to leave a comment, please click here

Microsoft provides privacy dashboard ahead of Windows 10 launch

Microsoft gave its privacy policy and service agreement a facelift Thursday, and offered users a new central clearinghouse to manage privacy settings for all the data the company keeps about them.The newly-minted privacy dashboard (included in the Security and Privacy section of Microsoft’s account administration page) gives users links to control data stored for personalizing their experience on Bing, what apps and services use their information, whether Microsoft personalizes ads for them and whether the company can market to them via email. It’s part of a move by the company to unify and simplify most of its service agreements and privacy policies for various products under one document.To read this article in full or to leave a comment, please click here

What outsourcing engagement model is right for you?

Outsourcing should be a strategic partnership, not a simple hand-off of duties to a third-party. Getting that right requires smart preparation.

Implemented correctly, strategic partnerships are a happy collaboration where expectations of delivery and results are clear from the start. By bringing in outside minds, it’s possible to innovate and drive your product to levels beyond what your internal team might have accomplished. New ideas can come from anywhere.

Week in Review

This week was a busy one. I had the opportunity to speak at a local NYC Ansible meetup, to a group of high school computer science students, and then on a panel at AnsibleFest yesterday in New York. Here is a short recap.

NYC Ansible Meetup - Tuesday June 2

Clearly the presentation was about network automation with Ansible. That probably goes without saying since it was an Ansible meetup! I’ve used these slides in other presentations throughout the year, so some are repetitive, but they usually hit some key points on the topic of network automation. Unfortunately, I did not know this was being streamed lived when it took place, but luckily the organizers recorded it too. Link is below.

Note: the presentation doesn’t start until about the 30:30 mark. From there on out, it’s about half presentation and then half live demo of using Ansible for Network Automation.

Facebook’s lean Android app is less than 1MB in size

Facebook has released a stripped down version of its Android app aimed at growing its service in developing countries and other areas with poor connectivity.The Facebook Lite app is less than 1MB in size—far less than the regular app—making it quick to download and install. It retains core features including the News Feed, status updates, photos and notifications, Facebook said. The company had been testing the app since at least January.The app started to roll out Thursday in some Asian countries, and will be available in parts of Latin America, Africa and Europe in the coming weeks.To read this article in full or to leave a comment, please click here

US reports massive breach of government personnel data

The U.S. is investigating a massive data breach that exposed personal information on around 4 million federal government workers, according to news reports Thursday.China is suspected of having a hand in the attack, described by an unnamed official as “one of the largest thefts of government data ever seen,” the Wall Street Journal reported.The attack targeted the Office of Personnel Management, a government agency tasked with hiring and retaining government workers. The same agency was breached last year, but this was apparently a separate attack.To read this article in full or to leave a comment, please click here

Your next digital security guard should be more like RoboCop

This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach.

Humans are clearly incapable of monitoring and identifying every threat on today’s vast and complex networks using traditional security tools. We need to enhance human capabilities by augmenting them with machine intelligence. Mixing man and machine – in some ways, similar to what OmniCorp did with RoboCop – can heighten our ability to identify and stop a threat before it’s too late.

The “dumb” tools that organizations rely on today are simply ineffective. There are two consistent, yet still surprising things that make this ineptitude fairly apparent. The first is the amount of time hackers have free reign within a system before being detected: eight months at Premera and P.F. Chang’s, six months at Nieman Marcus, five months at Home Depot, and the list goes on.

Beyond Alerts: Using orchestration to realize network self-healing

Managing modern networked systems and applications is daunting because infrastructure is complex and things can go wrong in so many parts of the technology stack -- servers, storage, network devices, applications, hypervisors, APIs, DNS, etc. How can you address the challenge?

A good place to start: problems that can solve themselves, should.

This is called “self-healing” in the systems management space. As our systems are increasingly virtualized, the opportunity to have our systems work around and self-correct issues has grown greatly in recent years.

The simplest example of self-healing is automatically restarting a service or process that stops or otherwise becomes unresponsive. It is important to keep in mind that this is a workaround and that automated activity of all sorts needs to be logged and monitored, in turn. If an application leaks memory such that it needs to be automatically restarted several times a day, that restart is not the fix, it’s a Band-Aid that is mitigating the impact while the developers responsible fix the application.

IDG Contributor Network: Brain uploads could become possible as PCs get more powerful

Living inside a machine is "definitely a possibility," according to a British neuroscientist. Dr. Hannah Critchlow,of Cambridge University, says that if a computer could be built to recreate the 100 trillion connections in the brain, it would be possible to live within programs.Critchlow's statement, at the Hay Festival, was reported by the Telegraph and Metro newspapers.To read this article in full or to leave a comment, please click here
