We can see in this context the need to know exactly where, when and how a piece of data is processed or stored. Compared with classic digital forensic, the field of cloud forensic has a lot of difficulties because data is not stored on a single place and furthermore it implies the use of virtualization technologies. In this paper we present a new method of monitoring activity in cloud computing environments and datacenters by running a secure cloud forensic framework. We talk in detail about the capabilities that such system must have and we propose an architecture for it. For testing and results we have implemented this solution to our previous developed cloud computing system.

It is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. The cloud computing model offers the promise of massive cost savings combined with in- creased IT agility. It is considered critical that government and industry begin adoption of this technology in response to difficult economic constraints. However, cloud computing technol- ogy challenges many traditional approaches to datacenter and enterprise application design and management. Cloud computing is currently being used. However, security, interoperability, and portability are cited as major barriers to broader adoption. In this context, a new need for IT experts is increasing: the need to know exactly how, where and in what condition is the data from the cloud stored, processed and delivered to the clients. We can say with great confidence that cloud computing forensics has become more and more a need in todays distributed digital world. In this paper we are going to present a new way in which we can integrate a full forensics framework on top of a new or existing cloud infrastructure. We will talk about the architecture behind it and we will present its advantages for the entire cloud computing community. We will present also the impact that our technology proposal will have on existing cloud infrastructures Copyright © 2006-2015 by CCC Publications
