Solid State Devices: Destruction Overkill?

September 19, 2018 at 8:54 pm by Heidi White

data-securityOrganizations frequently use paper shredders and computer media destroyers that are approved for the highest security materials they ever have, using that equipment for all of their materials in a single stream process.  Also common is to get the highest security level device that is available, even it goes well beyond the level of destruction mandated for or customarily used for the materials they actually have.  This could be called a “better safe than sorry” philosophy for media destruction.

For some information destruction equipment, like office paper shredders, choosing the most secure equipment for everything can often work out alright.  This choice will almost always be more costly than selecting the minimum security level device for each type of material for which it will be used.  However, a greater cost is often accepted in return for the confidence of having the greatest possible degree of information destruction.  For paper shredders, the highest security level means the smallest particle size, typically produced by NSA listed models.

SSD-destructionThe situation for solid state media destroyers is very different.  As a rule, dramatically greater hassle and cost will come from choosing the most secure possible device.  Solid state materials include whole solid state drives, flash memory sticks, thumb drives, circuit boards with flash storage, cell phones, and some smart cards. The highest security level for destroying these types of materials is the NSA standard, currently set at a maximum of 4mm squared, with compliant devices typically producing a particle size of 2mm x 2mm.  This particle size is required by the NSA for classified solid state items.

At the time I am writing this, the choices for NSA listed SSD destroyers are minimal.  There is only one office friendly device with extremely limited capabilities.  There are also a couple of large industrial type devices suited for folks with large spaces and large budgets.  With the current set of choices, getting an NSA listed SSD destroyer means enormous costs. Adding to the large initial cost, operational labor (due to very slow throughput), replacement parts, repairs, and preventive maintenance are very high for these machines.

shred ssdThe reality is that many organizations don’t need an NSA level of destruction for all of their solid state materials.  Often the classified items are only a very limited part of the mix.  In these cases, there are a few ways to save a lot of money and hassle.  If none of the solid state items to be destroyed are actually classified, there are machines that are many times faster, much more rugged, and are a small fraction of the cost of the NSA listed machines.  These devices produce high to extreme levels of destruction, well beyond any reasonable likelihood of reconstruction of any data.  If only a portion of the items in the mix is classified material, a major bump in productivity plus significant savings can come from using one of these lower cost devices for the unclassified items.  Even if an NSA listed SSD destroyer is brought in, the load on it can be reduced by using a second machine for the unclassified materials.  This type of dual stream process can save many times the cost of the second machine in terms of reduced purchases of repairs, maintenance, and spare parts.

When it comes to solid state media destruction, for folks whose materials are all or mostly unclassified, going with general purpose SSD destroyers offers these benefits over NSA listed SSD destroyers:

  1. Up to 20 times faster throughput
  2. Minimal service needs, even zero service needs through thousands of cycles
  3. Ability for most models to take whole SSDs with no assembly
  4. Models that run off of regular 120V wall current
  5. Dramatically lower cost for the equipment, ongoing service, and parts

Of course, technologies change over time.  New products will surely come out.  NSA certifications will change.  It is a moving parade over longer time scales.  But, for now, a great strategy for dealing with solid state media destruction that is partly or totally unclassified is to get a good general purpose SSD destroyer that provides a satisfactory level of destruction.

Destruction System reduces SSDs and other Electronic Media to Less Than 0.5mm Particles – Meets DIN E-7

June 13, 2018 at 4:06 pm by SEM

WESTBORO, MA — The SEM Model SSD1-HS from Security Engineered Machinery reduces solid state devices to waste particles of .5mm squared or less and meets DIN 66399 Standard E-7; smaller than the NSA requirement for sanitization of SSD devices per NSA/CSS EPL 9-12. Absolute destruction through repetitive high speed cutting of memory media ensure all data is properly sanitized.

Storage media is continuously cut until it is small enough to pass through a customer selected waste sizing system to meet customer’s security level or a specific DIN Level. Items that can be destroyed in the Model SSD1-HS include solid state boards, RAM, smart phone / cell phone components, SIM cards, USB flash drives, compact flash and even optical discs. The Model SSD1-HS is a compact, self-contained destruction system with all components housed within a custom enclosure for maximum sound, odor and dust control.

The Model SSD1-HS destruction capacity is dependent on the media being destroyed and the customer selected sizing screen.

An ergonomic operator interface allows easy viewing and control of all machine functions. The Model SSD1-HS features an interlocked feed slide with integrated feeding protocols ensuring proper metering of media through the data sanitization process. Safety interlocks prevent operation when any safety guard or panel is not in place or waste disposal is required. An air filtration system consisting of a carbon pre-filter and HEPA filter is also included.

Security Engineered Machinery, SEM, is an innovative designer and manufacturer of data-destruction equipment located in Westboro Massachusetts. SEM supplies mission critical EOL equipment to the US Federal Government including the DoD and other intelligence agencies, as well as large multinational datacenter operators. SEM’s engineering staff is available to assist customers with special products and systems that will sanitize any media / material down to stakeholder required sanitization levels such as high volume central destruction systems used by nationally recognized commercial banks and healthcare organizations. Areas of expertise include the destruction of hard drives and other mixed media and heavy-duty, high-capacity shredders for recycling applications.
