[Reference: HSMs are a core component of strong key management practices, often discussed in CASP+ material related to cryptography and data protection., B. Encrypting using server-side encryption capabilities provided by the cloud provider: With server-side encryption, the cloud provider typically manages the encryption keys. This means the organization is relinquishing some control over the keys., C. Encrypting using encryption and key storage systems provided by the cloud provider: Similar to option B, using cloud-provider-managed key storage systems means the organization doesn't have full, exclusive control over the keys., D. Encrypting using a key escrow process for storage of the encryption key: Key escrow involves entrusting a third party with a copy of the encryption key. This introduces a potential security risk, as the organization no longer has sole control over the key. Also, the key is not maintained within the organization., Reference: Key escrow is sometimes used for data recovery, but it's generally not recommended for maintaining the highest level of security and control over encryption keys. This is relevant to CASP+ discussions on risk assessment and key management best practices., Why A is the Correct Answer:, Control: On-premises HSMs provide the highest level of control over encryption keys. The organization has physical and logical control over the HSM and the keys stored within it., Security: HSMs are designed to be tamper-resistant and protect keys from unauthorized access, even if the surrounding systems are compromised., Compliance: In some industries, regulatory requirements may mandate that organizations maintain direct control over their encryption keys. On-premises HSMs can help meet these requirements., CASP+ Relevance: HSMs, key management, and data encryption are fundamental topics in CASP+. The exam emphasizes understanding the security implications of different key management approaches., Elaboration on Key Management Principles:, Key Lifecycle Management: Proper key management involves managing the entire lifecycle of a key, from generation and storage to rotation and destruction., Separation of Duties: It's generally a good practice to separate the roles of key management and data encryption to enhance security., Access Control: Strict access controls should be in place to limit who can access and use encryption keys., In conclusion, using an on-premises HSM for key storage is the best way to ensure that an organization maintains control over its encryption keys. It provides the highest level of security and control, aligning with best practices in cryptography and key management as emphasized in the CASP+ exam objectives., =================, ]
