Craig Balding's Cloud Security Blog
In my view, there are some strong technical security arguments in favour of Cloud Computing - assuming we can find ways to manage the risks. With this new paradigm come challenges and opportunities. The challenges are getting plenty of attention - I'm regularly afforded the opportunity to comment on them. However, let's not lose sight of the potential upside.
In this post, I walk through seven technical security benefits. Some are immediate, others may arise over time and have conditions attached (some unstated for the sake of brevity). However, I’m including the longer-range benefits now to raise awareness. Some of the outcomes listed are available today without the Cloud, but they are either complex and slow to implement (and thus less likely to happen) or prohibitive for capital cost reasons. I don’t claim this is a definitive list - it reflects where my thinking is today.
Some benefits depend on the Cloud service used and therefore do not apply across the board. For example; I see no solid forensic benefits with SaaS. Also, for space reasons, I’m purposely not including the ‘flip side’ to these benefits, however if you read this blog regularly you should recognise some.
On a sidenote, I believe the Cloud offers Small and Medium Businesses major potential security benefits. Frequently SMBs struggle with limited or non-existent in-house INFOSEC resources and budgets. The caveat is that the Cloud market is still very new - security offerings are somewhat foggy - making selection tricky. Clearly, not all Cloud providers will offer the same security.
Seven Technical Security Benefits of the Cloud
1. Centralised Data
- Reduced Data Leakage: this is the benefit I hear most from Cloud providers - and in my view they are right. How many laptops do we need to lose before we get this? How many backup tapes? The data “landmines” of today could be greatly reduced by the Cloud as thin client technology becomes prevalent. Small, temporary caches on handheld devices or Netbook computers pose less risk than transporting data buckets in the form of laptops. Ask the CISO of any large company if all laptops have company ‘mandated’ controls consistently applied; e.g. full disk encryption. You’ll see the answer by looking at the whites of their eyes. Despite best efforts around asset management and endpoint security we continue to see embarrassing and disturbing misses. And what about SMBs? How many use encryption for sensitive data, or even have a data classification policy in place?
- Monitoring benefits: central storage is easier to control and monitor. The flipside is the nightmare scenario of comprehensive data theft. However, I would rather spend my time as a security professional figuring out smart ways to protect and monitor access to data stored in one place (with the benefit of situational advantage) than trying to figure out all the places where the company data resides across a myriad of thick clients! You can get the benefits of Thin Clients today but Cloud Storage provides a way to centralise the data faster and potentially cheaper. The logistical challenge today is getting Terabytes of data to the Cloud in the first place.
2. Incident Response / Forensics
- Forensic readiness: with Infrastructure as a Service (IaaS) providers, I can build a dedicated forensic server in the same Cloud as my company and place it offline, ready for use when needed. I would only need pay for storage until an incident happens and I need to bring it online. I don’t need to call someone to bring it online or install some kind of remote boot software - I just click a button in the Cloud Providers web interface. If I have multiple incident responders, I can give them a copy of the VM so we can distribute the forensic workload based on the job at hand or as new sources of evidence arise and need analysis. To fully realise this benefit, commercial forensic software vendors would need to move away from archaic, physical dongle based licensing schemes to a network licensing model.
- Decrease evidence acquisition time: if a server in the Cloud gets compromised (i.e. broken into), I can now clone that server at the click of a mouse and make the cloned disks instantly available to my Cloud Forensics server. I didn’t need to “find” storage or have it “ready, waiting and unused” - its just there.
- Eliminate or reduce service downtime: Note that in the above scenario I didn’t have to go tell the COO that the system needs to be taken offline for hours whilst I dig around in the RAID Array hoping that my physical acqusition toolkit is compatible (and that the version of RAID firmware isn’t supported by my forensic software). Abstracting the hardware removes a barrier to even doing forensics in some situations.
- Decrease evidence transfer time: In the same Cloud, bit fot bit copies are super fast - made faster by that replicated, distributed filesystem my Cloud provider engineered for me. From a network traffic perspective, it may even be free to make the copy in the same Cloud. Without the Cloud, I would have to a lot of time consuming and expensive provisioning of physical devices. I only pay for the storage as long as I need the evidence.
- Eliminate forensic image verification time: Some Cloud Storage implementations expose a cryptographic checksum or hash. For example, Amazon S3 generates an MD5 hash automagically when you store an object. In theory you no longer need to generate time-consuming MD5 checksums using external tools - its already there.
- Decrease time to access protected documents: Immense CPU power opens some doors. Did the suspect password protect a document that is relevant to the investigation? You can now test a wider range of candidate passwords in less time to speed investigations.

Kudos to the Cloud Crowd for Re-Inventing the Wheel!
One thing 30 years in the IT industry has taught me is that the more things change, the more they stay the same. Another is that the only memory we seem to access is short-term. Yet another is that techno-marketeers rely on that, so they can put labels like "revolutionary" and "innovative" on platforms, products and services that are mere re-inventions of the wheel ... and often poor copies at that.
A good example is all the buzz about "Cloud Computing" in general and "SaaS" (software as a service) in particular:
Both terms are bogus. The only true cloud computing takes place in aircraft. What they're actually referring to by "the cloud" is a large-scale and often remotely located and managed computing platform. We have had those since the dawn of electronic IT. IBM calls them "mainframes":
The only innovation offered by today's cloud crowd is actually more of a speculation, i.e. that server farms can deliver the same solid performance as Big Iron. And even that's not original. Anyone remember Datapoint's ARCnet, or DEC's VAXclusters? Whatever happened to those guys, anyway...?
And as for SaaS, selling the sizzle while keeping the steak is a marketing ploy most rightfully accredited to society's oldest profession. Its first application in IT was (and for many still is) known as the "service bureau". And I don't mean the contemporary service bureau (mis)conception labelled "Service 2.0" by a Wikipedia contributor whose historical perspective is apparently constrained to four years:
Instead, I mean the computer service bureau industry that spawned ADAPSO (the Association of Data Processing Service Organizations) in 1960, and whose chronology comprises a notable portion of the IEEE's "Annals of the History of Computing":
So ... for any of you slide rule-toting, pocket-protected keypunch-card cowboys who may be just coming out of a 40-year coma, let me give you a quick IT update:
1. "Mainframe" is now "Cloud" (with concomitant ethereal substance).
2. "Terminal" is now "Web Browser" (with much cooler games, and infinitely more distractions).
3. "Service Bureau" is now "SaaS" (but app upgrades are just as painful, and custom mods equally elusive).
4. Most IT buzzwords boil down to techno-hyped BS (just as they always have).

For basic one-to-one voice or video calling solutions, WebRTC has proven to be a very powerful technology. Although WebRTC’s core functionality is to provide secure, real-time p2p media streaming, leveraging native platform features and server-side components brings up new communication capabilities for web and native mobile applications, allowing for advanced multi-user use cases such as video broadcasting, conferencing, and media recording.

In addition to all the benefits, IoT is also bringing new kind of customer experience challenges - cars that unlock themselves, thermostats turning houses into saunas and baby video monitors broadcasting over the internet. This list can only increase because while IoT services should be intuitive and simple to use, the delivery ecosystem is a myriad of potential problems as IoT explodes complexity. So finding a performance issue is like finding the proverbial needle in the haystack.

Early adopters of IoT viewed it mainly as a different term for machine-to-machine connectivity or M2M. This is understandable since a prerequisite for any IoT solution is the ability to collect and aggregate device data, which is most often presented in a dashboard. The problem is that viewing data in a dashboard requires a human to interpret the results and take manual action, which doesn’t scale to the needs of IoT.

A critical component of any IoT project is what to do with all the data being generated. This data needs to be captured, processed, structured, and stored in a way to facilitate different kinds of queries. Traditional data warehouse and analytical systems are mature technologies that can be used to handle certain kinds of queries, but they are not always well suited to many problems, particularly when there is a need for real-time insights.
