bring the destruction data

Best Practices

When a company collects customer data, there is a legal obligation to protect that data from the point of acquisition through to end-of-life decommissioning. It is the responsibility of the company to guarantee the media has been sanitized of all data before the media leaves the company's controlled facility. If not, improper IT Asset Disposition (ITAD) is a risk carried forward indefinitely.

A company's risk of a data breach from decommissioned hard drives and backup tapes can be reduced to 0% with a simple decommissioning process:

Secure Disposition of Magnetic Media

Step 1: Ensure no hard drives or tapes leave your facility without first being degaussed.

Step 2: Degauss all hard drives within your controlled, secure facility

Step 3: Physically destroy each hard drive immediately after it is degaussed

Step 4: Generate proof of erasure and destruction documentation

 

Explanation of Process:

Degaussing:

Degaussing sanitizes magnetic media (i.e., hard drives and tape of all data regardless of whether the media is working for non-functioning. In just seconds, a degausser encompasses the media with a strong magnetic pulse, completely eliminating all magnetic field patterns on the media.

Degaussing is the primary on-site method of data sanitation approved by the NSA for the erasure of Top Secret data. 

Degaussers are small (about the size of a CPU), light-weight (ranging from 35-105 lbs.), and can be carried or rolled into an office, data center, or warehouse. A degausser plugs into a standard wall outlet and takes seconds to complete a cycle. Degaussing is also environmentally friendly; it does not physically alter the external appearance of the hard drive allowing the degaussed hard drive to be recycled if desired.

Destruction:

Although physical destruction of a hard drive is not necessary after the drive has been degaussed, physically damaging the hard drive casing and bending the disk platters provides visual confirmation that the hard drive has been securely processed; discourages unscrupulous attempts to retrieve data from the drive, and indicates the drive is ready to leave the controlled environment of recycling or disposal.

Common methods of hard drive destruction include physical destroyers, such as the Garner PD-5, crushers, punchers, and shredders.

Verifying and Documenting the Data Erasure and Destruction:

Documented proof of data erasure and destruction is a necessity in our litigious society. A detailed record of the destruction process, including media serial/asset numbers, operator ID, date, time, location, degausser field strength, and type of physical destruction must be maintained for archival and audit purposes.

 

Secure Disposition of Solid-State Media

Step 4: Generate proof of destruction documentation

 

Explanation of Process:

Destruction:

Solid-state data (SSD) is stored as an electronic charge and therefore degaussing is not an effective method for sanitizing solid-state media. What is very effective is physical destruction.

Physical destruction of the media must occur while the media is inside your secure facility to protect the chain-of-custody. The destruction process should break, pierce, or waffle each data storage chip on the board.  Using a physical destroyer with an SSD option allows for both hard drives and solid-state media to be destroyed using one machine.  

Verifying and Documenting the Destruction:

Verify and document the destruction process with a proven destruction verification software system so you have a clear audit trail in case your data destruction practices are questioned. An integrated verification system connected to your physical destroyer ensures data consistency and removes operator reporting errors and inconsistencies.  Solid-state devices come in all shapes and sizes such as thumb drives, micro SD cards, and SSD drives. It is important to have a verification system that incorporates a photo of the media as well as diagnostic data from the destroyer such as crush depth and media type into the certificate of destruction report to provide a complete end-of-life audit trail of the media. 

Once these steps have been taken, the media can be safely removed from your secure facility.
