Transport/Communication Encryption is specifically designed to secure data in transit between locations like remote offices. It ensures confidentiality (privacy of the data) and integrity (no tampering of data), using either symmetric or asymmetric encryption methods, while also simplifying key management. Using Full-Disk Encryption would not be the best choice as it's designed to protect data at rest and does not inherently secure data in transit. Asymmetric Encryption by itself is not a complete solution for data in transit and could introduce complexity in key management. Steganography provides obfuscation but does not on its own ensure data encryption and integrity.
