VerifiedSecurity Fundamentals

A configuration file that contains API keys must be securely moved between two Linux servers in separate data centers. Which method offers the best balance of confidentiality, integrity, and adherence to security best practices?

Explanation

SCP transfers files through SSH, providing encrypted transport and integrity protection. SSH key-based authentication avoids password-based remote login and, together with a hardened SSH configuration, supports least-privilege access and reduces unnecessary exposure of sensitive API keys.
