Cloud Computing offers a sense of "vastness" in terms of storage and remote
processing. According to Simpson Garfinkil, a major challenge to any digital
forensics investigator investigating data within the cloud; can be an
inability to locate or identify data or code that is lost when single data
structures are split into elements.
This in effect directly impacts forensic visibility.
Within this ecosystem a major concern can be access to and the preservation
of data within an on-going digital forensic investigation. Of consideration
as mentioned in Part 1 - is that in a live and dynamic system such as the
cloud, it is virtually impossible to go back to an original state of data
after obtaining a "snapshot" for investigation.
Also of importance will be jurisdictional and legal ramifications pertaining
to the physical location of the cloud systems holding data under
Within the realms of digital forensics analysts traditionally performed
analysis on static data, either from a core dump, bit to bit imaging etc.
Recently we have seen an increased focus directed at the live forensics
environment. As users rely more on mobile and other remote devices to access
data on demand; data possibly held in some manner of cloud environment,
investigators will have to adapt their mode of investigations to suit.
I recall reading a marketing pitch a while aback where some vendor claimed
that an advantage of Cloud Computing is, an ability to conduct live forens... (more)
As stated in Part 1 my focus on this article will be more on the backscatter
technology as this seems to be where traveler scanning is heading and it
involves ionizing radiation. Currently we have varied opinions on this
technology with a major concern for the routine use of ionizing X-rays being
that of health issues.
Also mentioned was the fact that our skin being our largest organ, it may be
affected from backscatter skin surface scans in the long term. Continuing on
as stated earlier, per Wikipedia , there are three companies manufacturing
commercial backscatter X-ray dev... (more)

Lately in the IT community all the hype is on Cloud Computing. We have small
start-ups offering several variations of Cloud services as well as some of
the established big players (Google, Amazon, IBM, Novell (aimed at cloud
service providers),Sun) stepping up their offerings of cloud services.
But what exactly is Cloud Computing? Is it Virtualization? Is it services
that we accessed via a web browser over the years, something totally new, or
is it all of these,but just rebranded?
The term Cloud Computing started gaining traction when Google a... (more)
In an earlier article, I stated that we can view Service-Oriented
Architecture (SOA) as a synthesis of Enterprise Application Integration (EAI)
platforms with middleware tools. This evolution has evolved into an
architectural style which, entities can then utilize to execute and align key
services with their operational model to achieve strategies, goals and
