Security for security’s sake is dumb

June 5, 2008 Comments off

I added the Microsoft TechNet Radio RSS feed to my Zune desktop a long time ago, but never got around to listening to any of them.  While I’m working today I’m finally getting a chance to rectify that oversight.  🙂

I’m currently listening to an interview with Alan Levine from April 2006 (“TechNet Radio Security Series – an interview with Alcoa’s CSIO”).  At that time (maybe still today?) Alan was the Chief Security Officer for Alcoa, the aluminum company.  At one point (about 18 minutes in) he makes a great observation on how some people in IT try to secure everything for the simple fact that they can … “security for security’s sake” as he says.  It’s a bad idea, Alan explains…

“and if you don’t believe that, tonight when you go home park your car in the driveway with your wife.  You both get out and you go into the house, and before she can come in lock the door.  You’ll find out that security for security’s sake serves no purpose.”

I’m a huge fan of giving real-world, non-IT examples of tech scenarios to help people better understand what’s going on.  This is an awesome example of that … and one I’ll have to borrow!

Virtual ‘kumbaya’

June 22, 2007 Comments off

VMware and Microsoft both said they’re working behind the scenes to make it easier for virtualization users to migrate across their differing virtualization environments and run each other’s virtualized files.

But so far, it’s only virtual kumbaya. Neither one is saying how they’re going to do it.

I am a staunch believer that virtualization is the next big frontier in enterprise IT (and probably computing as a whole, all the way down to the consumer level).  I can’t wait too see what my datacenters and services are going to look like in 5-10 years.

I think it’s going to be a long and painful road to get there, as evidenced by Microsoft’s continuing delays and feature cuts of their Veridian hypervisor.

All that being said, I’m glad to see the major players in virtualization at least starting to talk.  I’m not going to hold my breath on the outcome – I’ve been burned by false hopes in the past.  But at least it’s a start.

It all depends…

Omar Shahine wrote a great article entitled Designing for Services Dependencies.  If you’re involved in IT at all this is a must read, no matter whether you’re a developer or on the operations side.

If only more developers would understand the dependencies they add into their systems!

Here’s a quick chart that talks about “The Nines”.  You’ll hear people talking about wanting to have “five nines” of availability.  Good luck with that!  🙂
