How to protect against shadow data security

RISKS [1]

Task 1. Read and translate the text:

Задание 1. Прочитайте и переведите текст:

Probably the first... (наиболее эффективный), step in reducing your vulnerability to shadow data leakage is knowledge that is exists (on your storage device). Knowing that shadow data potentially exists will ensure that you... (по крайней мере) weigh the risks and make informed decisions concerning the scrubbing of data, degaussing storage devices and in managing the risks.

U. S. government classified data handling instructions call for a certain specifications concerning the disposal of computer... (накопительные устройства). Data scrubbing through the use of multiple overwrites is on potential solution. While this procedure is not 100% fool-proof; it does... (значительно снижает) the likelihood of shadow data becoming a threat in your organization. Using old RLL-encoded drives, Peter Gutman of the University of Auckland speculated, in his document "Secure Deletion of Data from Magnetic Memory Devices", that overwriting a drive 35 times with varying hexadecimal values may force the write head to vary magnetic effect on the iron oxide particles to such an extent as to remove the shadow data. Still, there is... (нет гарантий) that software solutions will effectively wipe out all this information because the process relies on the drive's controller, which is not suited for this purpose.

High-intensity degaussing of a hard drive platter, floppy diskette, zip disks and tape is probably the... (лучший способ) to ensure the elimination of threats associated with shadow data. This is an effective process to use when storage devices are being retired from service. Be mindful that the degaussing of a hard disk drive must be performed after the platters have been removed. Otherwise, the hard disk drive will act as a protective shield and some shadow data may survive. The complete incineration of floppy diskettes, zip disks and tapes also... (может быть использовано) to remove any security threats associated with shadow data.

Corporate and government policies concerning the disposal of computer storage devices should always... (принимать во внимание) the potentials of shadow data as a potential data security risk. With knowledge and proper controls in place, shadow data should not become a security problem for most government agencies and corporations.

Task 4. Are these statements true or false?:

Задание 4. Определите истинность или ложность следующих предложений:

1. Knowing that shadow data potentially exists will ensure that you at least weigh the risks.

2. Data scrubbing through the use of multiple overwrites is on potential solution.

3. Overwriting a drive 35 times with varying hexadecimal values may force the write head to vary magnetic effect on the iron oxide particles to such an extent as to remove the shadow data.

4. The degaussing of a hard disk drive can't be performed after the platters have been removed.
