CIO Today: Security concerns cloud Virtualization

I just finished talking to Howard Fried, from Catbird , a Virtualization Security firm, and we spoke a great lengths about the security issues. Howard drew some interesting analogies with about Spaceshuttle, Startrek and interesting things that will need to be policed and secured. A lot of flexibility will be offered to the customer but it all has to happen while keeping security in mind. You don't do it, your business will leak out, leaving you naked!

This CIO article too addresses such issues:

I.T. managers worry that security attacks designed to exploit a hypervisor could infect virtual machines that reside on the same physical host, in what is known as a "virtual-machine escape".

If a virtual machine is able to "escape" the isolated environment in which it resides and interact with the parent hypervisor, industry experts say it's possible an attacker could gain access to the hypervisor, which controls other virtual machines, and avoid security controls designed to protect the virtual machine.

"The Holy Grail of security in the virtual world is to bounce out of the [virtual machine] and take control," says Pete Lindstrom, a senior analyst at Burton Group, in a recent webcast on virtualisation security.

But while there are documented attempts to execute a virtual-machine escape, some point out that a security disaster related to such an event has yet to be proved.

"To my knowledge, there has never been a hack that has allowed a security problem to propagate from one virtual host to another by way of the hypervisor technology," says Steve Ross, a consultant with Catapult Systems, which is helping logistics provider Transplace, based in Texas, deploy and maintain its VMware virtual environments.

Redhot Future Of IT Part I :Marketing yourself as IT professional

I had promised about the "RedHot IT Future Series" and so we discuss here how you should market yourself EFFECTIVELY as an IT professional in this new (and dangerous) web age! Web is the place where you're a hero today and villain tomorrow. While there are lots of professionals who are active on the web, not all are enjoying a good reputation as they got "personal" with others and got into a cockfight. The passive IT professional has nothing to lose but nothing to gain at all!

I know "marketing" might seem as a greasy term but the idea is to have the truth about you out there. You know you're a good person and your family knows that you're really smart person but the rest of the world doesn't!

So the question is how do I market myself on the web as a true "nouveau IT professional". A guy who companies will be tempted to pick up the phone as say "Hey, we wanna talk with you. Can you fly over to Palo Alto (or Guatemala or Johan…

Redhot Future Of IT Part 2 :Virtualized Workplaces

Click on the title to hear what I have to say, alternatively click here to listen to what I have to say here.

So what is a virtualized workplace? Does it mean it does not exist? That it's virtual? Well in a certain way YES. This is where the future of our workplace is going to be. Well it is already a reality in some countries.

OK lets start by asking ourselves these questions:
Do you really bond with your colleagues? (think Team cohesiveness)
Do you spend great amount of hours talking about great things that you will do together? (think collaboration)
Do you really feel that you give 100% at work? (think effectiveness)
What do you really miss at your desk? (think personalization)
Is your desk comfortable enough? (Again think optimizing personalization, OK you have done your best to make it your place)Does it really matter to your employer that you are there for him/her? (think commitment)
Or do you get micromanaged over petty issues? (think mismanagement)
Do you see your employees perfor…

A Collection of Threnodies : Part 1

Whale Fall
-----------------

Dress me up in my new threads
clasp my greasy palms
grease my hair
I'm ready for the fall


Watch at all the decadence
watching the avalanche
I'm slipping down
losing my buoyancy


What's become of us
where have we come
this far, this close
close to the doors


I hear them, sublimal chants
I'm on the run
I race through the human sea
I am the king!


I'm the slave
to my own undoings
I'm the jester in my courtyard
We jest as we run


We're strolling on that thin rope
we grope as we rope
we're true heros
we're the survivors


we're the scavengers
we're the friends
we're the lovers
we're the unbred


Soon awaiting the fall
we're lurking on us
we're osedaxing us
we're soon going to be done
we'll soon be arrested
