Which term describes the process when data you have created, used, shared, stored, and archived is no longer valuable?

• A. Data Integrity Management
• B. Data Destruction
• C. Storage Area Network
• D. Data Classification

Answer: (B)

When data has served its purpose and is no longer valuable, the appropriate action is to destroy it securely. Data destruction is about removing data from all storage locations—systems, backups, and archives—in a way that it cannot be recovered. This protects privacy, reduces risk of leakage, and helps comply with retention policies and legal requirements. Secure deletion methods include overwriting the data, degaussing, cryptographic erasure, or physically destroying the media. This concept differs from data integrity management, which focuses on keeping data accurate and uncorrupted, from data classification, which is about labeling data by sensitivity, and from a storage area network, which is just the infrastructure used to store data rather than a disposal process.
