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 Scalp Care 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 Dishwasher Drain Pump 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.
