Query: Forensic Issues and Techniques to Improve Security in SSD with Flex
  Capacity Feature   Over-provisioning technology is typically introduced as a means to improve
the performance of storage systems, such as databases. The over-provisioning
area is both hidden and difficult for normal users to access. This paper
focuses on attack models for such hidden areas. Malicious hackers use advanced
over-provisioning techniques that vary capacity according to workload, and as
such, our focus is on attack models that use variable over-provisioning
technology. According to these attack models, it is possible to scan for
invalid blocks containing original data or malware code that is hidden in the
over-provisioning area. In this paper, we outline the different forensic
processes performed for each memory cell type of the over-provisioning area and
disclose security enhancement techniques that increase immunity to these attack
models. This leads to a discussion of forensic possibilities and
countermeasures for SSDs that can change the over-provisioning area. We also
present information-hiding attacks and information-exposing attacks on the
invalidation area of the SSD. Our research provides a good foundation upon
which the performance and security of SSD-based databases can be further
improved.
