NIST 800-88 Hard Drive Destruction
The National Institute of Standards and Technology (NIST) has developed Guidelines for Media Sanitization – NIST 800-88. The NIST 800-88 publication is intended to assist organizations and IT system managers in making practical sanitization decisions based on the relative categorization and confidentiality of their information or data. This page specifically deals with NIST 800-88 guidelines associated with disposing of computer hard drives. According to NIST 800-88, shredding hard drives is the most secure and compliant form of data destruction. Erasing and deguassing hard drives is limited to destroy lower level information. NSA contractors must comply with stricter NSA/CSS hard drive destruction requirements.
NIST 800-88 Data Destruction Decision
A recent survey on hard drive disposal best practice conducted by The ITAM Review shows that Information Security is overwhelmingly the strongest consideration when disposing of IT equipment. Accordingly, CIOs want to know what NIST 800-88 regards as the most secure process for destroying hard drives and SSDs during the data destruction process.
The following flowchart summarizes the NIST 800-88 Sanitization and Disposition Decision Flow.
The bottom portion of the digital data destruction flowchart show details what processes should be followed for information classified as high security.
NIST for Small and Medium Sized Businesses
NIST now offers cybersecurity and data destruction guidance to small and medium-sized businesses (SMBs). Cybersecurity guidance from NIST couldn’t come sooner for SMBs as they are increasing becoming targets for hackers.
The Small Business Cybersecurity Act required NIST to offer SMBs resources to measure their current security protections against best practices. NIST data security guidance includes simplified cybersecurity framework, risk assessments and third-party breach education.

NIST 800-88 Required Documentation
NIST 800-88 describes three methods for sanitizing hard disk drives, 1) erasing, 2) degaussing and 3) shredding. NIST 800-88 considers physically shredding hard drives the most secure form of data destruction and should be used for all levels of confidential information. The decision to erase or physically destroy hard drives should be based on your organization’s policies and procedures governing data security and destruction. Many business and organizations are now required to have a written Identity Theft Prevention Program per the Federal Trade Commission’s Red Flags Rule. Conforming to NIST 800-88 guidelines requires proper documentation of data destruction or more commonly known as a Certificate of Destruction. NIST 800-88 documentation requirements.
