Cloud Forensics as a new technology

Introduction
Cloud computing is a new buzz promising to provide simplicity and delivering utilities based on virtualization technologies. It provides availability, convenience, elasticity, large storage capacity, scalability, speed, and on-demand network access to a shared pool of configurable computing resources while charging the consumer based on the usage (pay-as-you-go), (Mell &Grance, 2011).
Although, this new technology provides many advantages, but the surrounding security issues are causing for concerns where some of these issues can be listed as follows: the location of data, the ownership of data, access control, regulatory requirements, liability and accountability in a case of security breach, investigative support, long term viability of the provider, data segregation, and disaster recovery and continuity plans, (Gregg, 2010).
The accessibility of multiple data storage around the world built by the cloud venders while they are shared and exchanged can lead to the loss of security controls over the cloud hosted on third-party cloud computing platforms.
The fast adoption of cloud computing solutions among organizations forces digital forensics to follow in order to tackle the aroused challenges.

Digital forensics: evidence and procedure
Digital forensics is a process of analysing digital data while preserving its integrity. It includes the collection and preservation of sized media at the crime scene, validation, analysis, interpretation, documentation and presentation in a non-technical manner. In the cloud this process faces many challenges such as having limitations on the controls over the digital evidence. Digital evidence is any information of probative value which is stored or transmitted in a digital form based on SWGDE definition which presents many challenges due to its characteristics. The quantity of potential evidence, easily contamination, the number of suspects, authenticity and integrity,
