Rational Survivability

I saw a very interesting post on LinkedIn with the title PwC/TSB Debate: The cloud/thin computing will fundamentally change the nature of cyber security…

PricewaterhouseCoopers are working with the Technology Strategy Board (part of BIS) on a high profile research project which aims to identify future technology and cyber security trends. These statements are forward looking and are intended to purely start a discussion around emerging/possible future trends. This is a great chance to be involved in an agenda setting piece of research. The findings will be released in the Spring at Infosec. We invite you to offer your thoughts…

The cloud/thin computing will fundamentally change the nature of cyber security…

The nature of cyber security threats will fundamentally change as the trend towards thin computing grows. Security updates can be managed instantly by the solution provider so every user has the latest security solution, the data leakage threat is reduced as data is stored centrally, systems can be scanned more efficiently and if Botnets capture end-point computers, the processing power captured is minimal. Furthermore, access to critical data can be centrally managed and as more email is centralised, malware can be identified and removed more easily. The key challenge will become identity management and ensuring users can only access their relevant files. The threat moves from the end-point to the centre.

What are your thoughts?

My response is simple.

Cloud Computing or “Thin Computing” as described above doesn’t change the “nature” of (gag) “cyber security” it simply changes its efficiency, investment focus, capital model and modality. As to the statement regarding threats with movement “…from the end-point to the centre,” the surface area really becomes amorphous and given the potential monoculture introduced by the virtualization layers underpinning these operations, perhaps expands.

Certainly the benefits described in the introduction above do mean changes to who, where and when risk mitigation might be applied, but those activities are, in most cases, still the same as in non-Cloud and “thick” computing.  That’s not a “fundamental change” but rather an adjustment to a platform shift, just like when we went from mainframe to client/server.  We are still dealing with the remnant security issues (identity management, AAA, PKI, encryption, etc.) from prior  computing inflection points that we’ve yet to fix.  Cloud is a great forcing function to help nibble away at them.

But, if you substitute “client server” in relation to it’s evolution from the “mainframe era” for “cloud/thin computing” above, it all sounds quite familiar.

As I alluded to, there are some downsides to this re-centralization, but it is important to note that I do believe that if we look at what PaaS/SaaS offerings and VDI/Thin/Cloud computing offers, it makes us focus on protecting our information and building more survivable systems.

However, there’s a notable bifurcation occurring. Whilst the example above paints a picture of mass re-centralization, incredibly powerful mobile platforms are evolving.  These platforms (such as the iPhone) employ a hybrid approach featuring both native/local on-device applications and storage of data combined with the potential of thin client capability and interaction with distributed Cloud computing services.*

These hyper-mobile and incredibly powerful platforms — and the requirements to secure them in this mixed-access environment — means that the efficiency gains on one hand are compromised by the need to once again secure  diametrically-opposed computing experiences.  It’s a “squeezing the balloon” problem.

The same exact thing is occurring in the Private versus Public Cloud Computing models.

I was brainstorming a couple of Cloud things with Doug Neal and Mark Masterson the other day and whilst grappling for an appropriately delicious analog for Cloud Computing, my 5-year old approached me and asked to play the “burping beer game (iBeer)” on my iPhone.  Aha!

Whilst I have often grouped Cloud Computing with the consumerization of IT (and the iPhone as it’s most visible example) together in concert in my disruptive innovation presentations, I never really thought of them as metaphors for one another.

When you think of it, it’s really a perfect visual.

The iPhone is a fantastic platform that transforms using technology that has been around for quite a while into a more useful experience.  The iPhone converges many technologies and capabilities under a single umbrella and changes the way in which people interact with their data and other people.

In some cases we have proprietary functions and capabilities which are locked into the provider and platform.  We pay for this forced allegiance, but we tolerate it as necessary.  We also see the inventiveness and innovation of people for whom brute forcing their way into openness with jailbreaks is a reasonable alternative.

There’s lots of ankle biting as vendors and providers clamor to bring the familiar trademarks of the iPhone to their own platforms.  There are marketplaces being built around these platforms to open up new opportunities for collaboration, applications and experiences with the, gasp!, phones.

It’s true.  The iPhone is, at its heart, a phone, and we’ve had mobile phones forever.  Some complain that the iPhone is nothing more than a smartly packaged combination of technology we’ve already had for ages and that thanks to Moore’s law, we’re able to cram more and more stuff into smaller and smaller spaces.  That logic therefore dictates that the iPhone is the mini-me “mainframe” of mobility. 😉 And millions buy it still.  It’s like technology timesharing as the phone, Internet and mobility capabilities all compete for a timeshared swath of space in my pocket.

Yes, that’s right.  The iPhone is simply timesharing of functions on a phone. <snort>

To the detractors’ point, however, for all the innovation and exciting capabilities the iPhone brings, it has and continues to suffer from some seriously goofy limitations that in other platforms would be game stoppers, but people settle anyway, waiting for the technology to catch up and dealing with the implications as they become important (or not.)

The best example?  Cut and paste.  I had freaking cut & paste in my Newton 15 years ago.  The lack of C&P made certain things unusable on the iPhone let alone inconvenient and even insecure (having to copy and write-down complex passwords since I stored them in 1password, for example.)

However, I’ve purchased each revision of the iPhone as it came out and have been incrementally giddy with each new hardware/software combinaton, especially with the 3.0 software upgrade which finally gave me my beloved cut and paste 😉  The reality is that there are probably better solutions for my needs, but none that are so damned convenient and sexy to use.

The thing I love about my iPhone is that it’s not a piece of technology I think about but rather, it’s the way I interact with it to get what I want done.  It has its quirks, but it works…for millions of people.  Add in iTunes, the community of music/video/application artists/developers and the ecosystem that surrounds it, and voila…Cloud.

The point here is that Cloud is very much like the iPhone.  As Sir James (Urquhart) says “Cloud isn’t a technology, it’s an operational model.”  Just like the iPhone.

Cloud is still relatively immature and it doesn’t have all the things I want or need yet (and probably never will) but it will get to the point where its maturity and the inclusion of capabilities (such as better security, interoperability, more openness, etc.) will smooth its adoption even further and I won’t feel like we’re settling anymore…until the next version shows up on shelves.

But don’t worry, there’s an app for that.
