Which protocol is used by ACAS for communication between clients and servers?

• A. FTP (File Transfer Protocol)
• B. SMTP (Simple Mail Transfer Protocol)
• C. HTTPS (Hypertext Transfer Protocol Secure)
• D. SNMP (Simple Network Management Protocol)

Answer: (C)

The correct choice for the protocol used by ACAS for communication between clients and servers is HTTPS (Hypertext Transfer Protocol Secure). This protocol is designed to provide a secure channel over a computer network, utilizing encryption to ensure that any data exchanged between clients and servers remains confidential and integral. ACAS, which focuses on the security posture of Department of Defense (DoD) systems, utilizes HTTPS to protect sensitive information during transmission. This is particularly important in ensuring the integrity and confidentiality of the assessment data handled by the ACAS tool. The use of encryption prevents eavesdropping, tampering, and man-in-the-middle attacks, making HTTPS a vital component in safeguarding data communication in security-focused applications like ACAS. In contrast, protocols like FTP are primarily used for file transfers without encryption, making them unsuitable for the secure communications required in this context. SMTP is intended for sending emails, which does not align with the client-server communication model of ACAS. SNMP, while useful for network management, does not provide the same level of secure data transmission required for compliance assessments, thus reinforcing HTTPS as the optimal choice for ACAS operations.
