Top 3 Labs for Networkers to Get Started at Cisco’s DevNet

Today’s post gives a top 3 list: For you networkers, what are three labs to try at Cisco’s DevNet Zone, even before you have a lot of confidence with APIs?

As part of my role in the #CiscoChampion program, I wrote a recent blog post over at Cisco.com. For that post, I could pick any topic that I thought might be of interest to Cisco followers, and I ended up writing about Cisco’s DevNet Zone, Cisco’s software developer portal. I had a few more thoughts about labs beyond the other blog post, so I put those notes in this companion post. If you’re interested in Cisco’s DevNet Zone, check out both posts!

14 DRaaS vendors that will rescue you in a pinch

To the rescueImage by Flickr: Beverley Goodwin According to a Gartner report, the Disaster Recovery as a Service market originally emerged to address IT organizations' need to support increasingly aggressive recovery-time targets and more frequent and lower-cost testing while understaffed, or without requiring a significant time commitment by existing IT staff.To read this article in full or to leave a comment, please click here

Learn to Speak Your Peer’s Language with ipSpace.net Webinars

One of the reasons I started creating ipSpace.net webinars was to help networking engineers grasp the basics of adjacent technologies like virtualization and storage. Based on feedback from an attendee of my Introduction to Virtual Networking webinar it works:

I am completely on the Network side of the house and understand what I need to build for Storage/Data replication, but I really never thoroughly understood why. This allowed me to have a coherent discussion with my counterparts in DB and Storage and some of the pitfalls that can occur if we try to cowboy the network design.

Recommendation: if you have a similar problem, start with Introduction to Virtual Networking and continue with Data Center 3.0 webinar.

Revealed: The top 10 apps that companies hate

Companies are wary about what employees are doing on their smartphones. Be it data loss or time-wasting, a growing number of employers are actively stopping staff from using certain apps on company-controlled devices.After surveying the roughly 6,000 companies that uses its mobile security management software, MobileIron determined the top 10 consumer apps that are most often blocked or blacklisted at companies: Dropbox Angry Birds Facebook Microsoft OneDrive Google Drive Box Whatsapp Twitter Skype SugarSync It's perhaps no surprise that half of the positions in the top 10 are for file-sharing apps. Corporate IT managers are wary about giving users the ability to download and share internal files on apps that aren't under corporate control.To read this article in full or to leave a comment, please click here

PageFair says small percentage of users were at risk from attack

PageFair, an Irish ad analytics company, said Monday a small percentage of users were at risk after attackers compromised its systems over the weekend.CEO Sean Blanchfield wrote that 501 publishers that use the company's javascript tag were affected.Ninety percent of publishers have less than ten million page views per month, and 60 percent have less than one million page views per month, he wrote.PageFair has calculated that about 2.3 percent of the visitors to those sites would have been at risk of being infected.The attackers gained access to a key email account at PageFair and then reset the password for a PageFair account at a content distribution network (CDN).To read this article in full or to leave a comment, please click here

Winner claimed in $1 million iOS 9 hacking contest

A team of security researchers may have found a way to remotely penetrate the defenses of Apple's latest mobile OS, making them eligible for a $1 million reward. The money was offered in a contest run by a Washington, D.C.-based company called Zerodium, which is in the controversial business of buying and selling information about software vulnerabilities. It congratulated the winning team on Twitter Monday, though it didn't identify the researchers, which made its claim about finding a new security hole in iOS 9 impossible to verify.To read this article in full or to leave a comment, please click here

Speaking Notes: The Data Center Network Evolution

I will be presenting at the Cisco Connect Canada tour in Edmonton and Calgary on November 3rd and 5th, respectively. My presentation is about that three letter acronym that everyone loves to hate: SDN :-)

I will talk about SDN in general terms and describe what it really means; what we're really doing in the network when we say that it's “software defined”. No unicorns or fairy tales here, just engineering.

Next I'll talk about three areas where Cisco is introducing programmability into its data center solutions:

  • Application Centric Infrastructure
  • Virtual Topology System
  • Open NX-OS

Below are the notes I made for myself while researching these topics and preparing for the presentation. At the bottom of this post is a Q&A section with some frequently asked questions.

Calling All Switchers

Are you a switcher? That is, are you someone who has transitioned from one IT discipline to an entirely new IT discipline? Perhaps you were a storage gal for a long time, and now you’ve successfully transitioned into a networking career. Maybe you used to be a Windows admin, and now Linux is your thing. Or perhaps you were a networking guy, and now you’re coding like a madman. If this sounds like you, please read on!

If this describes you—or describes something you’re in the middle of doing—I’d love to talk to you. Please hit me on Twitter (I’m @scott_lowe), or drop me an e-mail (use [email protected], substituting the correct values). I promise it won’t take much of your time, and we can do this via whatever medium makes the most sense: e-mail, telephone, Skype, instant messaging, IRC…you let me know. I’m particularly interested in talking to folks to have made a really dramatic transition, not just moving from being a server administrator to being a virtualization administrator (let’s face it, those two roles are fairly similar).

Thanks, and I look forward to hearing from you soon!

Google patches critical media processing flaws in Android

New security patches for Google's Nexus devices address seven vulnerabilities, two of which are critical and could allow for remote code execution when handling media files.The updates, released on Monday, are part of Google's recently introduced monthly patch cycle and are available for Nexus devices running both Android 5.1 (Lollipop) and 6.0 (Marshmallow). The source code for the fixes will also be added to the Android Open Source Project (AOSP) over the next 48 hours.The most serious flaws patched in this release are tracked as CVE-2015-6608 and CVE-2015-6609, and are located in the mediaserver and libutils components of Android, respectively. Both vulnerabilities can be exploited remotely through specially crafted media files.To read this article in full or to leave a comment, please click here

Chaos Computer Club: Apple rejected TV-streaming app because of hacking iOS talks

Despite Apple having championed privacy and encryption, and having its most profitable year yet, the company is apparently not above censoring free speech on its Apple TV platform. The Chaos Computer Club claimed that Apple rejected the CCC's TV app that would allow viewers to stream the hacking conference because researchers have previously presented talks centered on hacking iOS.To read this article in full or to leave a comment, please click here

Worth Reading: Avago buys Broadcom

If the modern datacenter has taught us anything, it is that scale matters and as it turns out it matters for the manufacturers of the devices that go into various systems in the datacenter as much as it does for those who deploy and use those systems. It is with this in mind that we ponder the implications of the $37 billion acquisition of networking and wannabe server processor maker Broadcom by the recently very acquisitive Avago Technology, a maker of chips for optical networking, server networking, and storage controllers, among other things. via the platform
