The interest and excitement around virtualization is palpable. However, it seems like the security approaches in this area are similar to the constrains that a horse's ass put on the space shuttle design.
Virtualization security solutions today primarily focus on protecting the virtual OS, the virtual networks, or the hypervisor software itself. More specifically, most current virtualization security technologies are focused on preventing hypervisor root kits, providing intrusion detection, anti-malware, anti-virus, network security, etc. In the physical world, this is similar to individually protecting hardware, operating systems, and the networks that connect them. That is, the focus is mainly on protecting infrastructure and perimeter, not data. Protecting that data, however, should be the single most important aspect of virtualization security.
Here is why: Any execution environment requires four elements: devices/hardware/OS, networks, applications, and data. With the advent of virtualization, physical devices/OS are being replaced by flexible, on-demand virtual “devices,” networks are being virtualized and applications are being streamed down from virtual environments. Therefore, the only remaining “constant” element is the data itself - which also has a longer lifetime than the ephemeral virtual environment. While protecting the virtual infrastructure is important, I believe the primary focus for protection should be the data – the true IT asset.
Virtualization is a game-changer for computing and has forced the IT world to rethink its infrastructure; now virtualization security has to be rethought as well. An information-centric approach to persistently protecting the data itself is the only way to really benefit from virtualization and keep the data truly secure.
Or thinking about it another way - why was Google's approach to navigate the web using search better than the initial Yahoo approach of hierarchical mapping? Coz Yahoo was mapping an old yellow-book approach to managing data, while Google took advantage of the new medium.
I shall try and elaborate on my thoughts in upcoming posts...

Getting fired due to a breach?
Just got an email inviting me to a seminar - hosted by SecureState. But what caught my eye was this statement,
"7 out of every 10 breaches ends with someone losing their job"
I was shocked! 70% of all breaches result in the firing of someone involved in the breach? Or is it the failure to defend this breach resulting in the CISO losing her/his job?
I had never seen this research before and did not know this problem was so acute. Be very interested to know the source of this research. The seminar information is here.
Will post again when I find out more...

The importance of key management
As encryption and data protection becomes more prevalent, dont forget the equal importance of managing those keys. This seems to be the message from Jerome Wendt.
I think there are two sides to the story here - while I agree that managing keys is important, I think this is something users SHOULD NOT be concerned about. This is something the vendors should be focused on solving and not leave it to end users to stumble over.
Key management is hard and it makes sense to solve it at the product level rather than leaving it to implementation variances.

And the attacks keep coming...
Seems like the intensity and frequency breaches have just started to warm up! Even as we pat ourselves about the recent indictment of criminals we see reports of increased activity. Millions of cards stolen and more loss...
Brings us back to a hard question we have to ask ourselves - are we ready to tackle this seriously? Vendors, retailers, banks, government and consumers all have a huge stake in this (and don't forget, so does organized crime). However, it seems like organized crime is living up to its name - they seem a bit more organized about this. Not having looked at the numbers, but is feels like we are being pushed back and they currently have the upper hand...
Not a very PC thing to say, I know. However, we have to wake up to the reality and get more serious about this.

Twelve billion dollars!
Sounds like a Dr. Evil sound bite :). In fact this could be the potential impact of the 41 million cards stolen - according to security company Jefferson Wells. The amount is a result of simple multiplication - 41 million x $300 for each card lost. On the higher end, no doubt.
While I don't think the real cost is anywhere close to that (even by an order of magnitude), it is still a large number. Even at street price of $2 per card, someone must be making 41 million x $2 = $82M!
More scary to imagine, is where this stolen data is going, what kind of money they are making and what illegal stuff is being done with it.

Smackdown on data criminals
The long arm of the law finally flexed in a major indictment of criminals who were charged with hacking and stealing credit cards from major retailers.
Eleven folks were charged with the crimes ranging from conspiracy, computer intrusion, fraud and identity theft.
Interesting nuggets from the report:
- They hacked nine major U.S. retailers, stole and sold more than 40 million credit and debit card numbers...
- Apparently this is the single largest and most complex identity theft case ever charged in this country
I agree with the US Attorney - we need better ways to prevent such hacking. But one point is clear again in this case - those who hack work for increasingly sophisticated criminal enterprises and will deploy significant resources to steal as long as the returns are worth it.

Laptops can be seized at the US border
New rulings allow the Homeland Security to seize and analyze laptops as folks cross the border. Will this will increase the propensity of folks to encrypt their laptops or reduce it (thereby reducing suspicion)? I don't think businesses will look at this as another reason to encrypt - the majority would rather data not be stolen or lost than think about what a border agent might find on that machine.
For folks who have personal machines (maybe speaking for myself), I am not sure I would care much if a border agent looked through my laptop. But maybe I should - who knows what that information can be used for later?
