  Cloud computing is a relatively new technology which is quickly becoming one
of the most important technological advances for computer science. This
technology has had a significant growth in recent years. It is now more
affordable and cloud platforms are becoming more stable. Businesses are
successfully migrating their systems to a cloud infrastructure, obtaining
technological and economic benefits. However, others still remain reluctant to
do it due to both security concerns and the loss of control over their
infrastructures and data that the migration entails. At the same time that new
technologies progress, its benefits appeal to criminals too. They can not only
steal data from clouds, but they can also hide data in clouds, which has
provoked an increased in the number of cybercrimes and their economic impacts.
Their victims range from children and adults to companies and even countries.
On the other hand, digital forensics have negatively suffered the impact of the
boom of cloud computing due to its dynamic nature. The tools and procedures
that were successfully proved and used in digital investigations are now
becoming irrelevant, making it an urging necessity to develop new forensics
capabilities for conducting an investigation in this new environment. As a
consequence of these needs a new area has emerged, Cloud Forensics, which is
the result of the intersection between cloud computing and digital forensics.
