Final answer:
When the security categorization is high according to the NIST Guidelines for Media Sanitation, the media should be destroyed to ensure no data can be recovered. Media destruction includes methods like shredding, disintegration, or incineration.
Step-by-step explanation:
In the NIST Guidelines for Media Sanitation, if the security categorization is high and the media will not be reused, it should be destroyed. This means that the physical media should be completely and irrecoverably demolished to prevent any potential breach of sensitive information. For instance, hard drives should be shredded, disintegrated, or incinerated as appropriate. The guidelines provide specific methods of media sanitation that align with the security level of the data contained within. Destruction ensures that high security categorization data is safeguarded against any form of data recovery attempts, thereby maintaining the confidentiality and integrity of the information.
