Cloud Security And Data Protection Issues.
If there’s one concern that has been regularly rearing it’s head over the years whenever Cloud computing is mentioned, it is the protection of sensitive company data physically stored off-premise. The natural anxieties expressed at a time when MS deskbound computing was the predominant operating system and most business data was stored on software physically installed in the CPU under your desk or locked in the room next to the stationery cupboard just sound a little out of step, these days.
As we head into 2011 and deeper into the age of mobile apps, iPad downloads, Near Field Technology, Google Goggles and augmented reality, it’s fairly evident that the concept of accessing a ‘cloud resource’ of stored remote data, as and when required, onDemand, or as a service on a static or more likely, a mobile platform ‘reader’ or indeed, ‘thin client’, is already here in all but name.
The reality is that the various forms of Cloud computing, which we are all used to using in the form of email, VPN, Flickr and Facebook, for example, actually provides SMEs more protection, IT support and potential network security benefits from the cloud vendor than their own, often limited or non-existent in-house resources and budgets.
On a daily basis, the centralisation of company data provides reduced data leakage as a result of lost, corrupted, crashed, faulty or stolen CPUs, laptops, disks, USBs, back up tapes and remote hard drives. As thin client technology, such as DesktopLive, becomes prevalent, small, temporary caches pose less risk than transporting ‘data buckets’ in the form of laptops and USB datasticks.
Centralisation
In addition, central storage is easier to monitor, control and implement disaster recovery prevention contingencies . For example, a Cloud server can be instantly cloned by ‘forensic’ software if compromised, eliminating or reducing any service downtime. Inevitably, increased competition and business consumer demand will mean that Cloud service vendors will constantly strive to optimise performance by developing ever more efficient security software.
Security Testing
Change control builds, pre-strengthened and ‘secure’, are also primarily a proactive IT benefit of virtualisation based Cloud computing. Reduced exposure within production environments through patching offline means it is easier to test impact of security changes by producing a copy of your production environment, implementing a security change and testing the impact at low cost, with minimal startup time.
Economies of Scale
Deployed within a ‘public cloud’ service and thus, sharing the same application as a service, means only paying a percentage of security testing costs of the Software as a Service (SaaS) provider. Similarly with Platform as a Service (PaaS), there are potential cost economies of scale, as with password strength testing times, which are decreased by restricting activities to dedicated non-production machines, preventing the mixing of sensitive credentials with other workloads.
