Problems solved by technology

The ability to remove devices from the system means that data in the system could become vulnerable when a device is removed.
This vulnerability could increase the risk of privacy law violations and / or increase the likelihood that sensitive data will be released.
Furthermore, when storage devices are removed improperly, data stored in the system could be lost.
For example, if two disks are removed from a RAID-5 disk array, the data stored in the array will be lost.
In either case the resulting cost can be enormous.
A typical ten hour restore from backup could cost millions of dollars, and cause serious harm to a company.
Moreover, inserting devices into a system could introduce contamination such as foreign data and even viruses.
For example, in a system that enforces the WORM (Write Once Read Many) property on rewritable disks, allowing the disks to be removed and inserted back into the system could circumvent the enforcement of the WORM property and cause the system to become contaminated with rewritten data.

Embodiment Construction

[0011] The invention will be described primarily as a system and method for securing data within a storage system. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be evident, however, to one skilled in the art that the present invention may be practiced without these specific details.

[0012] Those skilled in the art will recognize that an apparatus, such as a data processing system, including a CPU, memory, I / O, program storage, a connecting bus and other appropriate components could be programmed or otherwise designed to facilitate the practice of the invention. Such a system would include appropriate program means for executing the operations of the invention.

[0013] An article of manufacture, such as a pre-recorded disk or other similar computer program product for use with a data processing system, could include a storage medium and program means reco...

Abstract

According to the present invention, there is provided a system for securing data with a storage system. The system includes at least one storage device. In addition, the system includes a security mechanism for recognizing an attempt to insert or remove the storage device. Moreover, the system includes a management unit to control the insertion and removal of the storage device.

Description

FIELD OF THE INVENTION [0001] This present invention relates generally to data security, and, in particular, to securing data within a system such that the data cannot be contaminated, lost, or leaked from the system even when data storage devices such as disk drives are removed from or added to the system. BACKGROUND OF THE INVENTION [0002] Storage systems are utilized to process and store sensitive data. This sensitive data includes medical records, financial data and even details of weapons simulations. Such data must be securely managed so that it is not contaminated, lost, or improperly leaked. Currently, such data is stored on data storage devices (e.g., disk drives) which tend to be readily replaceable to facilitate repair, failure, and migration to faster, cheaper and larger devices. [0003] The ability to remove devices from the system means that data in the system could become vulnerable when a device is removed. This vulnerability could increase the risk of privacy law vio...
