Data Destruction Standards
SF Bay Area

By adhering to industry best practices, DRM is able to ensure the confidential information of the client that resides on their media is never compromised.

Guidelines for Media Sanitization

DRM adheres to this standard when undertaking a hard drive wiping operation.

Not only will the logical storage location of a file be erased or deleted by overwriting, but also the whole media, to include all addressable locations. The goal of this overwriting process is to completely replace all sensitive data with non-sensitive random data.

Based on the sensitivity of the information contained on the media, the media should be overwritten a minimum of three times.

There are no longer references to specific sanitization methods in current editions. The standards of sanitization are left to the Cognizant Security Authority.

There are methods specified in the Clearing and Sanitization Matrix (C&SM) provided by the Defense Security Service (DSS). While the text of NISPOM itself never specifically described any methods for sanitization, past editions from 1995 and 1997 contained explicit sanitization methods included in the DSS C&SM table that was inserted after Section 8-306.
