Steve Wozniak chimes in on the Apple/FBI debate

At this point, it seems that there's truly no end in sight for Apple's ongoing legal battle with the FBI. While the FBI and the DOJ have made it clear that they want Apple to create a new version of iOS designed to bypass iOS security mechanisms, Apple has made it clear that it's not even going to entertain the idea. Quite the opposite, Apple CEO Tim Cook even categorized the FBI's request as akin to asking Apple to create the software equivalent of cancer.Over the past few weeks, many tech companies have come out in support of Apple. Indeed, any time a tech figure of any prominence has been interviewed in recent weeks, the topic of discussion invariably turns to mobile encryption.To read this article in full or to leave a comment, please click here

Network and system analytics as a Docker microservice

Microservices describes why the industry standard sFlow instrumentation embedded within cloud infrastructure is uniquely able to provide visibility into microservice deployments.

The sFlow-RT analytics engine is well suited to deployment as a Docker microservice since the application is stateless and presents network and system analytics as a RESTful service.

The following steps demonstrate how to create a containerized deployment of sFlow-RT.

First, create a directory for the project and edit the Dockerfile:
mkdir sflow-rt
cd sflow-rt
vi Dockerfile
Add the following contents to Dockerfile:
FROM   centos:centos6
RUN    yum install -y java-1.7.0-openjdk
RUN    rpm -i http://www.inmon.com/products/sFlow-RT/sflow-rt-2.0-1072.noarch.rpm
EXPOSE 8008 6343/udp
CMD    /etc/init.d/sflow-rt start && tail -f /dev/null
Build the project:
docker build -t sflow-rt .
Run the service:
docker run -p 8008:8008 -p 6343:6343/udp -d sflow-rt
Access the API at http://docker_host:8008/ to verify that the service is running.

Now configure sFlow agents to send data to the docker_host on port 6343:
The following articles provide examples of using the sFlow-RT REST API:
The diagram shows how new and existing cloud based or locally hosted orchestration, operations, and security tools can leverage sFlow-RT's analytics service to gain real-time visibility. The solution is extremely scaleable, a single sFlow-RT instance can monitor thousands of servers and the network devices connecting them.

TeslaCrypt ransomware now impossible to crack, researchers say

The latest version of the TeslaCrypt ransomware has tidied up a weakness in previous versions that in some cases allowed victims to recover their files without paying a ransom. Cisco's Talos research group found that TeslaCrypt 3.0.1 has improved its implementation of a cryptographic algorithm making it impossible now to decrypt files.  "We can not say it loud and often enough, ransomware has become the black plague of the internet," wrote Andrea Allievi and Holger Unterbrink, both security researchers with Cisco, in a blog post on Wednesday. "The adversaries are modifying and improving it in every version."To read this article in full or to leave a comment, please click here

Network Automation @Interop Vegas 2015

I’m happy to be given the opportunity to speak once more at Interop Vegas in 2016. No workshop for me this year, but I will be putting on three individual talks, all focusing on topics that have been very near and dear to me over the past year.

Last year I was very focused on putting the theory behind network automation into practical terms, and making it “real”. Over the past year I’ve seen rapid growth in adoption of these ideas, and I was happy to be just one very small part of helping to make that happen.

Since the last Interop, my career has steered me towards a more direct approach to network automation, specifically through software development. So I’d like to spend some time providing an overview of my sessions at the upcoming Interop Vegas 2016, which are all inspired by the last year of my career.

Air Force faces challenges managing drone force

As unmanned aircraft become a larger part of the Air Force a number of challenges have surfaced that could impact drone squadron efficiency.A Government Accountability Office report out this week stated that while the Air Force has made efforts to manage its unmanned aircraftpilots but has not fully addressed issues related to: “identifying personnel requirements, recruiting and retention difficulties, the potential use of Department of Defense civilians as pilots, pilots completing their required training and moving pilots through the training pipeline.”+More on Network World: What’s hot at the monster CeBit show?+To read this article in full or to leave a comment, please click here

This new discovery could put quantum computers within closer reach

One of the obstacles that have kept quantum computers on the distant horizon is the fact that quantum bits -- the building blocks with which they're made -- are prone to magnetic disturbances. Such "noise" can interfere with the work qubits do, but on Wednesday, scientists announced a new discovery that could help solve the problem.Specifically, by tapping the same principle that allows atomic clocks to stay accurate, researchers at Florida State University’s National High Magnetic Field Laboratory (MagLab) have found a way to give qubits the equivalent of a pair of noise-canceling headphones.The approach relies on what are known as atomic clock transitions. Working with carefully designed tungsten oxide molecules that contained a single magnetic holmium ion, the MagLab team was able to keep a holmium qubit working coherently for 8.4 microseconds -– potentially long enough for it to perform useful computational tasks.To read this article in full or to leave a comment, please click here

Attackers exploit Apple DRM weakness to infect non-jailbroken iOS devices

Attackers are exploiting a weakness in Apple's digital rights management technology to install malicious apps on supposedly protected, non-jailbroken iOS devices.In late February, security researchers from Palo Alto Networks found three malicious applications on the official App Store. An analysis revealed the malicious apps were part of a scheme to steal Apple IDs and passwords from Chinese users under the guise of an alternative app store.The more interesting aspect of the apps: In addition to being published on the official app store, they were also silently installed through software running on users' Windows PCs.An iOS device that hasn't been jailbroken, and hasn't had its security restrictions removed, should only be able to run apps downloaded from the App Store or installed through the iTunes software from users' PCs.To read this article in full or to leave a comment, please click here

Steam Stealer malware provides a thriving business for cyber thugs

A new Kaspersky Lab report (pdf) by security researchers Santiago Pontiroli and Bart P looks at the big business of Steam Stealers that “have turned the threat landscape for the entertainment ecosystem into a devil’s playground.”Wannabe cyber crooks might turn to malware which steals Steam credentials because it’s incredibly cheap. The report said $3 will buy usage rights for a Steam platform credential stealer and $7 adds source code and a user manual. Researchers said comparative malicious campaigns usually start at the $500 range. There are Steam Stealers which cost more, but “it would be hard to find any stealer being sold for more than $30.”To read this article in full or to leave a comment, please click here

Worth Reading: DROWN attack

More than 11 million websites and e-mail services protected by the transport layer security protocol are vulnerable to a newly discovered, low-cost attack that decrypts sensitive communications in a matter of hours and in some cases almost immediately, an international team of researchers warned Tuesday. More than 81,000 of the top 1 million most popular Web properties are among the vulnerable HTTPS-protected sites. -via ARS

Giveaway: Navigating Network Complexity

netcomplexI have one remaining copy of my latest book from the initial ten Addison-Wesley sent me on publication… What I’ve decided to do is sign it and give it away to one of my readers. What’s the catch? There are actually two.

First, you have to go to the contact form and leave me feedback with three design concepts (or other interesting things) you’d like to see me write about on this blog. I won’t do “how to configure” type articles, as I think there’s enough of that around on the ‘web. It’s useful stuff, but it’s not my “thing.”

Second, I can’t ship this thing out of the US.

I’ll ship the book, after I’ve signed it, to the person with the three best questions.

Digital rights group: Save security, reject FBI’s iPhone unlocking request

Digital rights group Fight for the Future is hoping to give voice to ordinary people concerned with the FBI's attempt to force Apple to help it unlock the iPhone used by a mass shooter.Fight for the Future's new Save Security campaign, launched Wednesday, will collect comments from people worried about the Internet security implications of the FBI's court request. Organizers will display the comments and read them aloud outside a California courthouse before a hearing in the case next Tuesday."We're actually trying to give a voice to people all over the world who are extremely concerned about this," said Evan Greer, campaign director for the group. Fight for the Future is trying to "bring those voices into the conversation so that it's not just a fight between a giant company and the government," Greer added.To read this article in full or to leave a comment, please click here

Cyberespionage groups are stealing digital certificates to sign malware

An increasing number of cyberespionage groups are using stolen code-signing certificates to make their hacking tools and malware look like legitimate applications.The latest example is a China-based hacker group that has launched targeted attacks against government and commercial organizations from around the world over the past two years.The group's activities were uncovered by researchers from Symantec in late 2015 when they detected a digitally signed hacking tool that was used in an attack against one of the company's customers.The tool, a Windows brute-force server message block (SMB) scanner, was signed with a digital certificate that belonged to a South Korean mobile software developer. This immediately raised red flags as a mobile software company would have no reason to sign such an application.To read this article in full or to leave a comment, please click here

Worth Reading: DRM and HTML5

The World Wide Web Consortium (W3C), which makes the core standards that the Internet runs on, is in the midst of a long, contentious effort to add “DRM” (Digital Rights Management1) to HTML5, the next version of the Web. Laws like the Digital Millennium Copyright Act (which has analogs all over the world) give companies the power to make legal threats against people engaged in important, legitimate activities. Because the DMCA regulates breaking DRM, even for legal reasons, companies use it to threaten and silence security researchers who embarrass them by pointing out their mistakes, and to shut down competitors who improve their products by adding legitimate features, add-ons, parts, or service options. The Web relies on the distributed efforts of independent security researchers, and its historic strength has been the ability of companies and individuals to innovate without permission, even when they were disrupting an existing business. -via the EFF
