Ontrack Japan, a Japanese subsidiary of KLDISCOVERY ONTRACK, a world -class data recovery / erasing service, announced that it will launch the data eraser verification service in the Japanese market on March 25, 2020.did.Last year (2019), the number of companies / organizations that have been demanding safe data erasure in the disposal media in Japan has increased in the wake of an administrative document leak due to unauthorized resale of hard disks in Kanagawa Prefecture.
Overview of products and services handled by ontrack
EVS is the latest data deletion guideline "SP 800-88 REV" for software / hardware tools for erasing data used by customers.1 (2014) A service that verifies and guarantees that it is compliant.In the United States, it has been provided for more than six years, and in addition to industry associations in industry that handles substantial information such as finance and healthcare, software vendors that develop data erasure tools, storage vendors that incorporate eraser tools into products, and data handling data.It is said that enterprise companies that set strict policies are used.
EVS extracts image files from recording media (HDD, SSD, USB memory, etc.) processed by customers using data erasure tools, and ontracks with special skills in data recovery are searching and analyzing "remaining data".Thoroughly carry out reports.As a result, it is guaranteed that the deletion tool is performing data erasing processing by correct means of NIST.
The EVS has two -level services according to the verification level required by customers.
First, the level Ⅰ searches and analyzes the remaining data in the area that users can access via the standard interface (SATA, SCSI, Fibre Channel, etc.).This includes search for algorithms that can not be restored.In the hidden area (HPA, DCO) in the media, only the judgment whether it exists (does not analyze the contents of the hidden area).
In Level I, in addition to the contents of level II, verification inside the hidden area is also performed.Furthermore, in the case of an HDD, a verification inside the re -assigned sector after a defective sector occurs is performed.Similarly, in the case of flash media such as SSD, protection is disabled by removing (tip -off) individual NAND chips from the board, and thorough verification including hidden areas and defective blocks (tip -off is performed (tip -off.Flash media after verification cannot be reused).
Apart from the EVS, it also provides a "code review Purge authentication service" service for the developer (such as software vendors, storage vendors, etc.) who develops and provides erasure tools.This is because the data recovery engineer and the development team of the tools provided by the customer and the development team are reviewed, and the tools are SP 800-88 REV..A guarantee that it conforms to the "Purge" standard of 1.Specifically, it will confirm that a specific command that can obtain the conformity to the standard will be executed.
By the way, one of the methods to prevent data on the recording media from reading is "physical destruction" and "external magnetic extinguishing" (in the case of magnetic media such as HDD).However, in a verification case that the US headquarters has worked on, some of the processes have been extracted due to insufficient processing, despite the fact that they have been processed.For this reason, the ontrack recommends that even when physical destruction or external magnetism is performed, it is always a pre -processing to overwrite overwriting with tools.
According to a verification case at the Ondruck US headquarters, data was extracted from the "processed" media of physical destruction and external magnetism media (the left is a physical destroyed drive that was actually extracted the data).
