Zone Based Firewalls

When I heard the word “Zone” my mind drafted to the very first form of VLANs I set up long ago; AppleTalk Zones.  AT Zones were a great idea ahead of their time and certainly set up the world to understand that digital partitioning based upon a logical grouping is a very good thing. As I stepped out of the Way-Back Machine, I thought of a more common use for zones in networking today; Zone Based Firewall Policies on the ASA.

Impressions from Voicecon!

Wow -- Cisco was in the house for Voicecon this year! For a company that was not taken seriously as a voice vendor a few years ago, this year we were rocking this conference. Walking around in my Cisco t-shirt, I was stopped several times by folks who complimented the shirts (simple black t-shirt with Cisco in white on the front) and one guy admitted to me he was sick of the “awful colors” on t-shirts. Then I overheard a passing comment about how “Cisco people are EVERYWHERE”. 

So besides Cisco being highly visible, what other impressions am I taking away from Voicecon this year?

Clouds. Cloudy. Cloudless. Partially cloudy? Clear as day?

Trying to figure it all out

 

Seems I hear the word “cloud” an awful lot these days. Cisco did a funny video on “what is cloud computing” that calls out what we all know -- “cloud” is a word often used and frequently understood. When it comes to putting your collaboration tools into the cloud, it all becomes even more confusing. TechWiseTV is addressing this whole “collaboration in the cloud” notion head on! Join us for these upcoming events as we find out if the forecast is cloudy, but clear!

I’m Looking Thru You

There are a bunch of reasons to hide info. Normally, if you REALLY want to hide data you just encrypted it with folks in your key circle and its Newcastle time. However, sharing stuff with folks outside of the “circle of trust” meant hiding it in plain site. We still do it for practice to see if folks could find any clues to keep our skills sharp. Kinda like a Paul McCartney is dead thing for us geek type folks. Back in the day, we used to hide URL or code in plain site by using Based64 encoding then hide them in the common URL and slip thru just about everything. Things have sure changed big time.
