KIP 7.2 File Shredding (Overwriting)
KIP 7.2 Software includes the Department of Defense NISPOM specifications to securely delete (overwrite) all
image data after a print, copy or scan job has been completed. KIP7.2 File Shredding (overwriting) processes
and scheduling is configurable using KIP PrintNET.
The KIP PrintNET File Shredding configuration allows administrators or key operators to select one or both of the
following file shredding processes:
1. After each copy, print or scan job, KIP 7.2 software will remove all remnants of file image data.
2. 7.2 Software may also be configured via KIP PrintNET to shred all blank hard disk drive space on a daily,
weekly or monthly basis.
Organizations using file shredding software may wish to use both processes. That is they wish to shred image
data after each print, copy or scan job plus shred blank hard drive space on a daily, weekly or monthly basis.
The shredding process time can vary depending on the amount of data or empty hard drive space to be
overwritten.
NISPOM (National Industrial Security Program Operating Manual) paragraphs 5-704 and 5-705 set out
requirements for the destruction of classified data that is no longer required. The appropriate file shredding
procedure to be used is based on the classification of sensitivity of the information and the type (size, capacity
and coercivity) of the media.
NISPOM outlines the clearing and sanitizing of data with a matrix. This matrix outlines the method of clearing
and sanitization of hard disk drives (Rigid Disks). In order to comply with NISPOM standards for rigid disks, KIP 7.2
software removes all image data and temporary image data used during the copy, print and scan process.
The KIP three pass file shredding process complies with the NISPOM specification which consists of overwriting all
image data locations with a character, its compliment and a random character. This method ensures that all
image data can no longer be accessed using a data recovery device.
KIP 7.2 File Shredding (Overwriting) Technical Details
Overwriting is a process whereby unclassified data are written to storage locations that previously held sensitive
data. To satisfy the DoD (Department of Defense) clearing requirement, it is sufficient to write any character to
all data locations in question. To purge AIS (Automated Information Systems) storage media, the DoD requires
overwriting with a pattern, then its complement, and finally with another pattern; e.g., overwrite first with 0011
0101, followed by 1100 1010, then 1001 0111. The number of times an overwrite must be accomplished depends
on the storage media, sometimes on its sensitivity, and sometimes on differing DoD component requirements. In
any case, a purge is not complete until a final overwrite is made using unclassified data.
