Is Data Retention Still Necessary in the Age of Smartphones?
By Michael Spreitzenbarth and Sven Schmitt
It is well known that smartphone operating systems persistently store location information in their local storage for various reasons. However, less well known is probably the fact that also various applications do this, too. In this article we will give you some hints where you can find this data on Android smartphones as well as we will present a system with which all this information can be extracted and visualized at the same time. We will also provide you with a comparison of the quality and quantity of location data gathered through data retention in contrast to the data gathered by forensic acquisition.

By Dmitry Solop
This article reveals the internals of one of such algorithms in application to recovering email databases and individual email messages in RFC -822 format, discussing quirks and issues the developers faced when implementing content-aware recovery of users’ emails. The article comes from the developers of numerous data recovery tools employing signature-search algorithms in their products. Expertise shared by the developers will help computer users better understand strengths and weaknesses of much-touted content-aware algorithms.

Head in the Cloud – Feet on the Ground
By Daniel Kario and Ariel Berkman
In the last couple of years we have been witnessing a trend of moving internal IT systems to the “cloud”. The delivery of computing as a service rather than a product, whereby shared resources, software, information and systems are provided as a utility over the internet. The main motivations for this process are to increase the efficiency of the IT department with cost savings and improved management. The typical and reasonable assumption is that the availability of the data in the cloud will be as good as the availability of the systems of the company before the move to the cloud. Indeed, cloud service providers are carefully defining the SLA for the availability of the cloud based service in their offering, but what about the availability of the data and the its backup (and restore) policy?

What’s Wrong With My Drive?!?
By Ken Krauss
Although the computer world is moving towards solid state technology in hard drives, a majority of the hard drives in use today have moving parts, and where there are moving parts, there are increased chances for failure. The parts inside your hard drive are moving at amazing speeds within microscopic tolerances of one another and your data is saved in a few grams or at most a few ounces of metal and ceramics. Most of us really take for granted the miracle of technology….

An Interview with Dmitry L. Kisselev
By Nick Baronian
One observation is that we haven’t seen a significant difference in the size of the data set stored in the cloud from an enterprise level. On the other hand, as one would suspect, consumers tend to store less data in the cloud, because most consumers just don’t have the same amount of data as a business entity would. Unrelated to the size of the data set, the value attached to the data is what dictates whether a customer wants our services or not.
