You have a storage media with some data and you make efforts to remove this data. After performing this, you analyze that the data remains present on the media.
Which of the following refers to the above mentioned condition?
A . Object reuse
B . Degaussing
C . Residual
D . Data remanence
Answer: D
Explanation:
Data remanence refers to the data that remains even after the efforts have been made for removing or erasing the data. This event occurs because of data being left intact by an insignificant file deletion operation, by storage media reformatting, or through physical properties of the storage medium. Data remanence can make unintentional disclosure of sensitive information possible. So, it is required that the storage media is released into an uncontrolled environment.
ANS: C and B are incorrect. These are the made-up disasters.
ANS: A is incorrect. Object reuse refers to reassigning some other object of a storage media that has one or more objects.
