Understanding the Duties of a User of Cryptographic Controlled Items

What are the duties of a user of cryptographic controlled items?

Answer:

The duties of a user of cryptographic controlled items include ensuring the confidentiality of cryptographic keys, safeguarding cryptographic devices and materials, following proper procedures for key management, and reporting any suspected security incidents. So the correct option is 5.

The Duties Explained:

1) Ensuring the confidentiality of cryptographic keys: Users must protect the secrecy of cryptographic keys to prevent unauthorized access to encrypted data. This involves storing keys securely and using them only as intended.

2) Safeguarding cryptographic devices and materials: Users should physically secure cryptographic devices (such as hardware security modules) and ensure that cryptographic materials (such as smart cards or USB tokens) are not lost, stolen, or tampered with.

3) Following proper procedures for key management: Users must adhere to established key management practices, including generating strong keys, securely distributing them, regularly rotating keys, and properly disposing of keys when no longer needed.

All of the above duties are necessary for maintaining the confidentiality, integrity, and availability of cryptographic systems and protecting sensitive information.
