IT Security Skills Anyone Can and Should Learn

I’ve been teaching IT security awareness for several years and I try to get those in attendance of the classes to learn some basic IT security skills. These basic skills build on each other and there is some cross over, but ultimately this blended set of security skills can help anyone stay safe online. As with any sport you always start by learning the fundamentals, and while no one skill can get you into the game or keep you safe online, they can definitely make you ready for either.

Physical Security

With free Wi-Fi available in coffee shops and many fast food restaurants I constantly see people leaving their devices unattended and this lapse can allow someone to walk off with the device unnoticed. Think about your device and the amount of data it may contain. The device may have your whole world stored on it! If someone takes your laptop, tablet, or phone it is so much more than having the device stolen, but the data it contains. Besides this Wi-Fi example other scenarios to pay attention to your device is when going through airport security or leaving the device in plain site while stored in the car. Continue reading

Finding Older Articles While The Blog is Migrated

If you hadn't noticed, the Revolution Wi-Fi website was recently migrated from Blogger to Squarespace. While I like the new look on the website, some of the features on the old site aren't yet replicated on the new site. Additionally, cached web search results still point to old URLs causing "webpage not found" errors from Google and others.

If you're looking for older blog posts or pages, you have two options:

Go to the old website still at http://www.revolutionwifi.blogspot.com
OR
Add the "/revolutionwifi/" directory into URL address for any blog post
Example:
http://revolutionwifi.net/2013/05/apple-ios-fast-roaming-with-aerohive-wi.html
Becomes:
http://revolutionwifi.net/revolutionwifi/2013/05/apple-ios-fast-roaming-with-aerohive-wi.html

Additionally, all of the categorized article topics are available on the old website at http://revolutionwifi.net/revolutionwifi/p/article-archives-by-topic.html

Finally, I've fixed all of the old URL links embedded within blog posts that were broken right after the blog migration due to the different directory structure. Ugh! But I've fixed this now... so all good there :)

I will also be adding Search and Categories to the new website once I have time. Thanks for your patience while I complete this work!

Cheers,
Andrew von Nagy

Away from WordPress to Jekyll on Github

Use Rate-Limiting to Alleviate Link Saturation

At some point in time you may come across a scenario in which you notice a WAN link at a branch site is being saturated. You then have to weigh your options to mitigate the saturation because it can cause intermittent network outages and other issues. In this scenario we will use rate-limiting on the […]

Cisco Live 2015 – Customer Appreciation Event Featuring Aerosmith!!

Yes, you heard me right. Aerosmith!

One of the most looked forward to social events for Cisco Live has always been the Customer Appreciation Events (CAE). Cisco rarely let’s us down when throwing this shindig, and has amazed us in the past with renting out resorts, baseball stadiums, and even Universal Studios.

This year, the CAE will be held on Wednesday June 10th at 7:30 inside Petco Park which is just a short walk from the convention center. With Aerosmith headlining this event it is sure to be huge! So if you haven’t already registered for CLUS15, be sure to do so NOW!!!

In other news, it seems that CDW is sponsering a new outdoor social media area for us to connect and hang out by the waterfront. Currently I believe this to be in addition to the normal social media hub that Cisco has been providing us since 2012.

This rendering of the area seems to indicate that it is located behind the convention center, probably in this area…

If you have any questions about this years event please reach out to @CiscoLive on twitter, or on Facebook!

Cisco Live 2015 – Announcements – I Don’t Want to Miss a Thing

In case the above video has not given it away, the CAE band on Wednesday June 10th @ 7:30 at Petco Park for Cisco Live 2015 is none other than Aerosmith! We have had some great bands over the years (KISS, Lenny Kravitz, Imagine Dragons, OK GO, just to name a few) and I suspect that this […]

A Quick Introduction to Consul

For reasons that (hopefully) will become clear in the relatively near future, I decided I needed to take a look at Consul, a distributed service discovery tool and key value store. I know Consul’s description sounds like a mouthful of buzzwords, but it’s pretty accurate. This post provides a quick introduction to Consul, in which I’ll break down what Consul does and how it works (at a high level). I’ll then build on this introduction in later posts.

There’s a lot to Consul, so let’s start by breaking down the description of Consul, which I provided as “a distributed service discovery tool and key value store”. What does this mean, exactly?

Consul is distributed. This means it runs as a cluster of systems so that there is no single point of failure. Consul uses a gossip protocol (known as Serf) to manage cluster membership, failure detection, and general orchestration. Managing cluster state via Serf is only part of the picture, though; the cluster must also manage consistency via a consensus protocol known as Raft. (Raft is the same consensus protocol used by etcd, for example.)
Consul is also a service discovery tool. Applications can register with Continue reading

Plexxi Pulse – Big Data is Driving Datacenter Infrastructure Development

You may have seen last week that we partnered with Cloudera, certifying the Plexxi Switch on Cloudera’s Enterprise 5 platform.

This partnership, while exciting for us and our partners, plays a larger role in the IT landscape as a whole. According to an article this week by Arthur Cole of Enterprise Networking Planet, this move embodies Cole’s belief that networking infrastructure development is increasingly being driven by Big Data applications. He cites the key challenge as not finding somewhere to store all the data (e.g. storage) but rather how to make it available to “diverse and disparate sets of resources quickly and at a relatively low cost.”

He closes out with his piece by admitting that there’s still progress to be made with this technology. Nevertheless, we’re proud to be leading the charge.

Below please find a few of our top picks for our favorite news articles of the week. Enjoy!

InformationAge: Converged infrastructure: a networking panacea or just another nice idea?

By Ben Rossi

It’s a real-time, data-heavy, multimedia world. Legacy networks with their siloed environments are simply not designed to deliver today’s enterprise demands, which are focused more and more on delivering applications Continue reading

Does Infinite Bandwidth Mean You Don’t Need SDN?

Musing: Could We Replace PCIe Bus With Ethernet Switch ?

I've been thinking about how a data centre architecture would look if we replaced the PCIe bus in servers with an Ethernet fabric. It's more doable than most people think.

Forming a Local User Group

I just read a short post by Lindsay Hill titled Doing Community Programs Right. I think the points made are accurate and well-founded. Prior to working for Cisco, I was part of the “CLN Designated VIP Program”. I had the opportunity to connect with others in and around the industry. I think these online communities are great and there is a wealth of knowledge sharing that happens. During key conferences many of our paths cross and even more interesting conversations happen.

I’d personally like to bring some of those concepts into the local communities I work in. I think many of the same tenants would be important. I wouldn’t want a local group to be about any single vendor (even Cisco) or partner. It would be really interesting to just get a bunch of people together that wanted to share their technology challenges and how they are addressing them.

If you have started such a group, I’d love to hear what worked and what didn’t. Were you able to get attendance even in smaller or rural communities? Maybe you are located in Central Kentucky or East Tennessee and would like to work together in such an effort? If so, reach out to Continue reading

Going Over the Edge with your VMware NSX and Cisco Nexus

What could possibly be more fun than connecting your awesome new NSX gear to your Cisco Nexus gear? For the life of me I really don’t know. All right then. Lets do it!

Lets kick things off with this email question I received from a reader.

Hi Brad, In our environment we have two prevailing server standards, rackmounts and UCS. I read your excellent NSX on UCS and 7K design guide and the section on not running routing protocols over the VPC links makes sense. My related question concerns how we can achieve a routing adjacency from the NSX Distributed Router to the N7K with a rack mount with 2x10gbe interfaces connecting to 2x7Ks via VPC? (we don’t use the NSX Edge Router).

This reader has politely pointed out that my VMware NSX on Cisco UCS and Nexus 7000 design guide could have provided a bit more detail on NSX Edge design. I totally agree. There’s no time like the present, so let’s dive into that now and stir up some content that might end up in the next version of the guide.

All right. We won’t worry too much about the form factor of the servers right now. Whether Continue reading

Whiteboarding Cisco ACI on Software Gone Wild
