Which of the following are authorized means of destroying key tape?

Burning or disintegrating key tape is an authorized method of destruction because it effectively reduces the material to ash or small particles, making it impossible to reconstruct the data that was contained on the tape. This process ensures that sensitive information does not fall into the wrong hands and is in line with secure destruction policies that govern the handling of classified or sensitive cryptographic materials.

The chosen method aligns with best practices for operational security, which stipulate that information must be destroyed in a manner that prevents recovery or reconstruction. Techniques like burning and disintegrating are specifically designed to completely eliminate any trace of the key tape.

Other methods mentioned, such as recycling or burial, do not adequately eliminate the risk of data recovery. Recycling might allow for recovery of the data if the tape is not completely broken down, while burial does not guarantee that the data cannot be accessed later. Shredding continuously can be effective, but it may not be the standard or preferred method for destroying key tape in all circumstances, depending on the specific policies in place.
