Add NIST 800-88 to Your DoD Data Destruction Playbook

It’s time your IT asset disposal program manager ditches a murky understanding of DoD data destruction(Department of Defense 5220.22-M) by adding a clearer understanding of the NIST 800-88 (National Institute of Standards and Technology 800-88 Guidelines for Media Sanitization).

The DoD data destruction standard does not provide the adequate specifics an organization or business will require in order to run a secure program in a real world operation. The DoD does provide broad guidelines that should be adhered to by any organization maintaining or disposing of sensitive data.

The NIST 800-88 Guidelines, however, provides a detailed roadmap for creating a data destruction program built on the principles of identifying risk, life cycle stage of media, selecting and implementing appropriate methods of destruction, verifying and overseeing success, and documenting procedures and work performed.

“We perform DoD data destruction” has been a mantra of the ITAD (IT asset disposal) industry for well over a decade. But when one pushes for more specifics from a vendor or program manager one is likely to find inconsistent interpretations of the standard from a belief that it exclusively refers to three pass binary wiping, seven pass binary wiping, to a misconception that only physical shredding and pulverization of media can achieve data security.

In reality the DoD data destruction method does have recommended standards for two step erasure of drives using a clear and binary pass overwriting. It also includes basic standards for the removal of physical identifiers, chain of custody documentation, and physical destruction of optical media. The DoD standard does not recommend any specific tools, software, machinery, or provide any types of certifications to vendors or products.

The NIST 800-88 provides a clear manual that guides IT professionals to select the appropriate tool by the life cycle, risk level, and type of media. For example the document points out that a degausser should never be used for solid state media. Since SSD media is not magnetic media the degausser would not destroy the data on the chip sets. This type of granular knowledge is a must have for every IT asset manager.

Here at ITAMG we help our clients understand the NIST 800-88 model and how to develop custom programs that address unique business, industry, and regulatory compliance requirements.

Hard Drive Disposal Options

Proper handling of end of life computer equipment and electronic media is critical to avoiding costly data breaches and debilitating exposures to your business and client data.  Your options for hard drive disposal should not be limited by archaic security policies, vendor capabilities, or lack of in-house expertise or access to industry leading tools.    

The below is a quick guide to the common tools and methods utilized by sophisticated IT asset disposal providers and IT departments alike.

Binary wiping and secure erasure:

Many times referred to as Department of Defense (DoD) three pass erasure, secure erasure writes multiple passes of binary code over a drive’s data to eliminate the path to the data.  The term DoD erasure is an asset disposal industry and IT shorthand and it should be noted that no software or erasure method is specifically endorsed by the DoD.  The method is a commonly accepted software tool for destroying data on magnetic and solid state media.

Having a contracted erasure service or in-house capability to securely erase machines is ideal to reuse machines in your environment, sell machines to a computer liquidator at optimum value, and ship or relocate machines that are not encrypted. 

Enterprise erasure tools should include reporting and verification utilities that allow organizations to save detailed certificates of destruction to the NIST 800-88 standards as well as identify drives that do not wipe to one hundred percent satisfaction.  When drives fail to wipe securely the user can quarantine and use another physical destruction method. 

DoD erasure is a method approved in the NIST 800-88 Guidelines for Media Sanitization in certain situations, but is not recommended for media that has higher risks associated to an exposure or contains top secret data. 

Hard Drive Shredding and Media Pulverization

Hard drive pulverizing or media shredding are terms commonly used for the industrial shredding of electronic media.  Although the equipment can be expensive for many business to own and maintain, many organizations utilize the method with the help of various asset disposal or document shredding service providers.  This method is ideal for quickly and cost effectively destroying large quantities of hard drives, optical media, flash drives, and other electronic storage. 

Hard drive shredding can be performed off-site at a vendor’s facility or on-site utilizing specialty shredding equipment typically deployed by the tier one IT asset disposal providers like IT Asset Management Group. 

Hard Drive Punching

Smaller machinery like hard drive punchers are ideal for eliminating the risk of shipping live and accessible data by first punching the drives before shipping or relocating the drives for the final shredding and recycling process.  Punchers are utilized where the large footprint of a shredder would not be possible or cost effective.  This method is ideal for small quantities of drives and is typically not cost or time effective for the destruction of large quantities of media.

Much like hard drive shredders there are hundreds of different kinds of hard drive punchers and some are not as effective for solid state drives or other types of media.  It is important to research and understand what a specific machine or service provider is able to do on a case by case basis. 

Degaussing Hard Drives

Degaussing hard drives is another solution ideal for smaller projects where an industrial hard drive shredder may not be available in the geographical area or economically appropriate for the project.  Degaussers use powerful magnets to destroy data on hard drives and other media but does not work for solid state hard drives or flash media.

Degausser machines are no longer the prevalent tool that they once were due to the superior output of shredders and more effective verification methods of enterprise erasure software utilities.  Nonetheless, the tool remains active due to security policies that have been written and not updated or where other tools prove to be near impossible to deploy.
