安全なデータ・端末の廃棄 | 国民のためのサイバーセキュリティサイト

This page explains methods to prevent information leakage when disposing of computers and storage media. It emphasizes establishing unified procedures through information managers. Four disposal methods are detailed: using data erasure software, hiring professional services, physical destruction, and cryptographic erasure. Key precautions include using specialized software for SSDs, carefully selecting trustworthy vendors, confirming complete disk destruction, and keeping recovery keys separate from computers during disposal. Cryptographic erasure, which involves securely destroying decryption keys, was added to government cybersecurity standards.
