What is classified information can be destroyed using which of the following methods?

Classified information requires specific methods for destruction to prevent unauthorized disclosure. The acceptable methods vary depending on the classification level and the type of media. Here's a breakdown:

• Burning: Incineration in an approved incinerator is a common and highly effective method. The incinerator must be designed and operated to completely destroy the material, reducing it to ash. This is generally suitable for paper documents.

• Shredding: High-security shredders, meeting specific standards (like NSA/CSS specifications), are acceptable for paper documents, microforms, and some optical media. These shredders produce particles small enough to make reconstruction virtually impossible. See more about shredding methods.

• Pulping: This involves reducing paper to a slurry, rendering it unreadable. Pulping is often used for large volumes of paper documents.

• Melting/Smelting: For metal objects containing classified information (e.g., certain electronic components), melting or smelting to a point of complete destruction is often required.

• Degaussing: This method uses a strong magnetic field to erase data on magnetic media (hard drives, tapes). The degausser must be approved for the classification level of the data being destroyed. Degaussing may not be sufficient for certain high-security classifications, in which physical destruction is necessary after the degaussing is complete. More information about degaussing

• Physical Destruction: This involves physically destroying the media to the point where data recovery is impossible. This can include pulverizing hard drives, breaking optical discs, or otherwise rendering the media unusable. See more about physical%20destruction.

• Overwriting: In some cases, data on electronic storage media can be overwritten with random data multiple times, making the original data unrecoverable. The specific overwriting standard needs to meet the requirements for the classification level. This is often used in conjunction with other methods, such as degaussing.

Important Considerations:

• Policy and Procedures: Always follow established agency or organizational policies and procedures for destroying classified information.

• Witnessing: Destruction often requires a witness to verify that the destruction was completed properly.

• Documentation: Maintain records of the destruction, including the date, method, and type of information destroyed.

• Approved Equipment: Use only equipment that has been approved for destroying classified information at the specific classification level. Approved equipment for classified information destruction method.
