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
What is SOA? One can say that the synthesis of Enterprise Application
Integration (EAI) platforms with middleware tools and concepts evolved into
what we know today as Service Oriented Architecture.
SOA then represents a standards based architectural blueprint with an
emphasis on business centric services and transactions rather than that of
technology oriented objectives: In other words an architectural style which
businesses can use to execute and align services with their business model to
achieve their business strategy, goals and objectives.
For instance, an end-user reques... (more)
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)
With the advent of Web 2.0 and onward, the rise of the terminology and
concept we call Cloud Computing, coupled with an increase in the manner
technologies are being used, not only by corporations but by individuals as
well, comes an increased drive to ensure that risk is managed, effective
security measures to protect identities are implemented, and efforts are
expended to ensure privacy is maintained.
A few years ago, in their quest to implement and maximize on the benefits of
Service-Oriented Architecture (SOA), researchers at Microsoft separated SOA
into four areas (1) viz.
Over the last three weeks due to the nature of my IT security job, I have
traveled through major airports at least eight times.
With all the commotion recently regarding the airports new back-scatter X-ray
machines (privacy, health, etc.) I wanted a firsthand look/feel at this
experience. While I am sensitive to and an advocate for issues of privacy
regarding persons with medical conditions and children, at 15 pounds
overweight I don't think any airport security personnel will take
pleasure in looking at a scanned image of me. Far from it, I hope I don't
give them any nightmares... (more)
