Non-console administrator access to any web-based management interfaces must be encrypted with technology such as ________________.

The requirement for non-console administrator access to web-based management interfaces to be encrypted is critical for ensuring the security and confidentiality of sensitive data during transmission. HTTPS is the correct choice because it is an extension of HTTP that incorporates encryption through TLS (Transport Layer Security). This encryption protects data from being intercepted or tampered with by malicious actors while traversing the network.

Using HTTPS ensures that any information exchanged between the client (the administrator's browser) and the server hosting the management interface is safeguarded, which is particularly important for sensitive administrative tasks that involve the configuration and management of systems and data.

In contrast, FTP (File Transfer Protocol) and Telnet are not secure protocols; they transmit data in plain text, which leaves it vulnerable to interception. Similarly, HTTP (Hypertext Transfer Protocol) does not provide any encryption, making it inadequate for accessing administrative interfaces securely. Therefore, choosing HTTPS aligns with best practices for securing administrative access, helping organizations maintain compliance with security standards like PCI DSS.
