Establishing a method to erase or clear cluster tips is an example of securing the following:
Data in transit
Data at rest
Data in use
Data in motion
A computer hard disk is divided into small segments called clusters. A file stored on a hard disk usually spans
several clusters but rarely fills the last cluster, which is called cluster tip. This cluster tip area may contain file
data because the size of the file you are working with may grow or shrink and needs to be securely deleted.
Data stored on the hard drive is called data at rest.
