Imprisoned and censored voices around the world

The number of individuals in prison around the world for raising their voices online is on the rise. In 2014, the Committee to Protect Journalists found that over half of imprisoned journalists were arrested for activities conducted on the Internet. In a 2015 report, Reporters Without Borders cited 178 incidents of imprisoned “netizens” in just a selection of twelve countries. Now that individuals can speak up without the need for institutions or gatekeepers, states choose the most direct way to take away their power: incarcerating them, and taking them offline. via the offline project

This is something every engineer, every blogger, and everyone who has a passion for free speech can help with. We live in a world that increasingly sees free speech as some sort of monstrously abnormal concept (even in the US); this is a fight we need to take up if any of us expect to be able to have a conversation about anything other than whether you should use EIGRP or IS-IS on a particular network.

We need to stand up for everyone who speaks, even if we don’t agree with them.

This is important.

Nest aims for central role in connected homes, enticing developers to integrate

The big winners in connected homes will be vendors of whole platforms, not individual products, and Google's Nest division is pushing hard to play that role. After pioneering Thread, a low-power networking protocol, Nest is now introducing an application layer that device and appliance makers can use to integrate their products tightly with Nest's. The new tool, called Weave, is for direct interactions between devices without resorting to processing in the cloud. That's good for in-home connections that are fast, don't require much energy and work even if the home's Wi-Fi network is down, said Greg Hu, senior manager of the Nest platform. Nest already uses Weave in its own products.To read this article in full or to leave a comment, please click here

The price of free: how Apple, Facebook, Microsoft and Google sell you to advertisers

Jumping from Windows 7 directly to Windows 10 has to be something like a farmer visiting Times Square. Live Tiles flash and move. A nice assistant named Cortana always hovers nearby. Click on the wrong spot and you could be whisked away elsewhere on the Web. And there are always people asking who you are, where you live, what you like...Because the latest version of Windows is always asking for information in the guise of being helpful, it’s easy to think that Microsoft’s the poster child for the collective attack on your digital privacy. But it’s not.MORE ON NETWORK WORLD: 26 crazy and scary things the TSA has found on travelers In fact, there are plenty of other companies who feel perfectly entitled to require you to hand over your personal info before they open their doors. On a day where Microsoft clarified what it does with your data to try and soothe your fears, a Bloomberg feature profiled Facebook’s “unblockable” ads, while a new Google program revealed that advertisers can now tune ads to who you are just by knowing your email address. To read this article in full or to leave a comment, please click here

New Android vulnerabilities put over a billion devices at risk of remote hacking

Newly discovered vulnerabilities in the way Android processes media files can allow attackers to compromise devices by tricking users into visiting maliciously-crafted Web pages.The vulnerabilities can lead to remote code execution on almost all devices that run Android, starting with version 1.0 of the OS released in 2008 to the latest 5.1.1, researchers from mobile security firm Zimperium said in a report scheduled to be published Thursday.The flaws are in the way Android processes the metadata of MP3 audio files and MP4 video files, and they can be exploited when the Android system or another app that relies on Android's media libraries previews such files.To read this article in full or to leave a comment, please click here

IPv6 Support in VRF on Catalyst 3k

I was looking for information on running IPv6 in VRF on the Catalyst 3k platform and there wasn’t much information available. I tried running IPv6 in VRF on Catalyst 3560 with correct SDM profile but got this error message:

Switch(config-vrf)#address-family ipv6
 IPv6 VRF not supported for this platform or this template

I checked with Cisco and you need to have Catalyst 3560-X/3750-X with release 15.2(1)E for IPv6 to be supported in a VRF. This means the feature is not supported on the non X models.

The feature is also available on the 3650/3850 platform with IOS-XE 3.6.0E.

I hope this information helps someone looking for IPv6 support in VRF.

In Pursuit of the CCIE

Just a short post to let you know this blog is not dead. I have not written anything in several months. While I have several posts that are partially complete, I have not been able to finish them…..yet.

For the past several months, I have been busy studying for the CCIE Wireless lab exam. Prior to that, I was sort of working towards the CCIE Route/Switch written and lab exam. I wasn’t fully committed, so my studying was sporadic at best. My heart just wasn’t in forcing myself to learn more about IPv6, multicast, MPLS, and some of the other blueprint items.

Somewhere along the line it changed. Maybe it was having another co-worker who was serious in his pursuit of the CCIE Wireless. Maybe it was that my job working for a reseller had me doing more and more Cisco wireless work. Maybe I just liked the fact that wireless was hard. I’m not really sure. I just know that at some point, a switch flipped inside my head and I just decided to go all in on my studies. Honestly, I should have done this years ago, but the timing just didn’t seem right.

I’ve been studying Continue reading

Startup NodePrime decloaks, wants to manage your whole data center

Voice hackers can record your voice then use morpher to trick authentication systems

It's easy for someone with potentially malicious intentions to record your voice, as you leave traces of your voice when simply talking somewhere out in public, during mobile phone calls, in videos posted on social networking sites, or even when sending a recorded voice greeting card. Your voice is considered to be unique enough to serve as an authentication of your identity.But after studying the implications of commonplace voice leakage and developing voice impersonation attacks, researchers from the University of Alabama at Birmingham warned that an attacker, in possession of only a very limited number of your voice samples, with "just a few minutes worth of audio of a victim's voice," can clone your voice and could compromise your security, safety, and privacy.To read this article in full or to leave a comment, please click here

Microsoft’s Windows chief Myerson falls short of addressing Windows 10 spying concerns

After a month of stern accusations, including one from yours truly, the chief of Microsoft's Windows group addressed user concerns over privacy and information gathering in a blog post.Since its launch two months ago, Windows 10 has been dogged by a number of privacy concerns, ranging from machine IDs to keylogging to spying on your Cortana queries. Windows 7 and 8 were also drawn into the controversy, as Microsoft back-ported some of its telemetry gathering functions to the older operating systems, and the company was also found to be downloading the multigigabyte installation files to Windows 7 and Windows 8 machines without user permission.To read this article in full or to leave a comment, please click here

Jeb Bush is a cyber-weenie

Jeb Bush, one of them many 2016 presidential candidates, has numerous positions on "cyber" issues. They are all pretty silly, demonstrating that not only he but also his advisors profoundly misunderstand the issues.

For example, his recent position opposing "NetNeutrality" regulations says this:
these rules prohibit one group of companies (ISPs) from charging another group of companies (content companies) the full cost for using their services
Uh, no, that's how Democrats frame the debate. ISPs charging content providers is actually a very bad thing. That we Republicans oppose NetNeutrality is not based on the belief that "charging content companies" is a good thing.

Instead, NetNeutrality is about technical issues like congestion and routing. Congestion is an inherent property of the Internet. NetNeutrality shifts the blame for congestion onto the ISPs. NetNeutrality means the 90% of Comcast subscribers who do not use Netflix must subsidize the 10% who are.

Or at least, that's one of the many ways Republicans would phrase the debate. More simply, all Republicans oppose NetNeutrality simply because it's over-regulation. My point is that Jeb Bush doesn't realized he's been sucked into the Democrat framing, and that what he says is garbage.


A better example is Jeb's position Continue reading
