Which of the following are challenges associated with key management?

Key management is a critical aspect of cloud security that ensures the confidentiality, integrity, and availability of cryptographic keys. Each of the factors listed plays a significant role in key management challenges.

Key storage is a challenge because securely storing cryptographic keys is essential to prevent unauthorized access. Keys need to be protected against theft, loss, or misuse, making secure key storage solutions, such as hardware security modules (HSMs) or specialized key management services, crucial.

Access to the keys also presents a significant challenge. Ensuring only authorized personnel or systems have access to cryptographic keys is critical to maintaining security. If access controls are inadequate, it could lead to vulnerabilities where attackers may gain access to sensitive decryption keys.

Backup and replication are essential to ensure key availability and resilience. However, managing backups of cryptographic keys must be done carefully to avoid compromising security. If keys are backed up improperly or without sufficient protection, they could be exposed or lost, leading to a potential loss of the ability to decrypt data.

In summary, the correct answer indicates that challenges associated with key management encompass all the mentioned factors, each playing a vital role in maintaining the security and integrity of cryptographic practices.
