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 ... (more)

Live Forensics and the Cloud - Part 1

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)

Examining the Impact of Airport X-Ray Technologies - Part 2

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 [4], there are three companies manufacturing commercial backscatter X-ray dev... (more)

Introducing Cloud Computing: A Gentle Overview

[Adopted from my BLOG December 2009] 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)

Service-Oriented Architecture & Cyber Security

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 objectives. Most who interact with or have interacted with the Department of Defence (DoD), will know of the various domains through which operations are implemented. As with any effective entity within the federal realm, t... (more)
