Information Security beyond the Endpoint

...for Secret and Top Secret Requirements
European Standard EN 15 713
Released in 2009, this regulation now sets a European
standard for information assurance. Replacing the former
DIN 32 757 and BS 8470:2006, it defines requirements for
mechanical secure destruction of confidential material in
8 security levels. High security data destruction happens
at level 8 with a particle size of in average 10 mm² and
a maximum width of 0.8 mm.
Particle surface: < 10 mm²
DIN 32 757-1
For almost 30 years the internationally recognised DIN was
the guideline for data security. In total it defined 5 security
levels. The top level 5 specified a maximum particle size
of 10 square millimeters for indecipherable shredding of
obsolete data storage media. This equals over 6,000
individual particles for one sheet of A4 format paper.
DIN 32 757-1 does not adress optical media destruction.
British Standard BS 8470:2006
BS 8470:2006 gives recommendations for the management
and control of collection, transportation and destruction of
confidential material to ensure that such material is disposed
of securely and safely. The recommendations apply to a
company’s main business premises and any holding sites.
Particle surface: < 10 mm²
DIN 33 858
This German standard refers to the erasure of data stored
on magnetic media. It defines the minimum requirements
for erasing devices and gives guidelines for the field strength
that needs to be used according to the type of data carrier
being destroyed. This field strength ranges from 350 up
to 5,000 Oe on three levels.
NATO SDIP-293
Within the military alliance of NATO this standard gives rules
for destruction of obsolete media. These items are split up into
paper and non-paper material. Main methods for destruction
are shredding, burning, disintegrating, smelting or degaussing.
Particle surface paper shredding: 5 mm²
NSA/CSS Specification 02-01
To protect national security, military and government
agencies the U.S. National Security Agency (NSA) released
a standard for paper shredders in 2003. NSA/CSS Specification
02-01 outlines the required shred size for document paper
cross cut shredders for government agencies disposing of
Top Secret or classified documents.
Particle surface: < 5 mm²
NIST Special Publication 800-88
While NSA / CSS gives rules for U.S. military or government
agencies, this publication released in 2006 gives guidelines
for media sanitization in U.S. commercial organizations.
Unlike most of the other standards it covers a large scope
of media primarily split into two groups: Hard copy and
electronic. The guideline deals with the trends in data storage
media and how the information can be deleted efficiently
by means of shredding, disintegration, pulverization or even
incineration.
Particle surface shredding: 5 mm²
