![]() An important factor to reach the full potential delivered by cloud computing techniques is the reduction of uncertainty which is currently addressed by EU’s cloud strategy. ![]() networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction” The European Union highlights in their digital agenda the high value of cloud computing for businesses and the governmental sector. According to NIST, “cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e. cloud computing is a technology that evolved from technologies of the field of distributed computing, especially grid computing. ![]() It has been introduced to optimize the general usage of IT infrastructures. Keywords : Cloud Computing, Digital Forensics, Cloud Forensics, Hypervisor Forensics, Evidence Correlation 1 Introduction In recent years, cloud computing has gained vastly in importance. Therefore we introduce the reader to the topic of evidence correlation within cloud com- puting infrastructures. cloud computing setups typically consist of several virtualized computer systems. ![]() As this paper represents an extended version of our paper presented at the ARES 2012 conference, we describe digital forensics investigations at the hypervisor level of virtualized envi- ronments in greater detail. The benefit for the reader of this paper is therefore a clear overview of the challenges and opportunities for scientific developments in the field of cloud forensics. In the first part of this paper we focus on the current state-of- the-art of affected fields of cloud forensics. The enormous available computing power can be leveraged to process massive amounts of information in order to extract relevant evidence. But, due to its dynamic nature, cloud com- puting also offers several opportunities to improve digital investigations in cloud environments. Nowadays digital investigators face various technical, legal, and organizational challenges to keep up with current developments in the field of cloud computing.
