Which protocol is commonly used for secure communication in network monitoring?

• 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 protocol commonly used for secure communication in network monitoring is HTTPS (Hypertext Transfer Protocol Secure). HTTPS is an extension of HTTP and uses secure encryption protocols, such as SSL/TLS, to encrypt the data transmitted over the network. This security feature ensures that any data exchanged between the web browser and server is protected from eavesdropping and tampering, making it essential for maintaining confidentiality and integrity during communication.

In the context of network monitoring, HTTPS provides a secure method for accessing web-based monitoring tools and dashboards. These tools often require the transmission of sensitive information, such as system metrics, configuration data, and performance statistics. By using HTTPS, network administrators can ensure that this data is not exposed to unauthorized access or interception, which is crucial for the security of the overall network monitoring process.

The other protocols listed have different primary functions. FTP is primarily used for transferring files and does not inherently provide secure encryption. SMTP is utilized for sending emails, and while it can be secured through additional measures, it is not specifically designed for secure monitoring. SNMP, while widely used for network management and monitoring, typically operates without encryption in its default configurations, making it less secure compared to HTTPS for sensitive data transmissions.

Thus, HTTPS stands out as the best
