Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) — Question 182

An organization is cooperating with several third-party companies. Data exchange is on an unsecured channel using port 80. Internal employees use the FTP service to upload and download sensitive data. An engineer must ensure confidentiality while preserving the integrity of the communication. Which technology must the engineer implement in this scenario?

Answer options

• A. RADIUS server
• B. web application firewall
• C. X.509 certificates
• D. CA server

Correct answer: C

Explanation

Implementing X.509 certificates provides a secure method for ensuring both confidentiality and integrity through encryption and digital signatures. The other options, such as RADIUS server and CA server, do not directly address the need for secure data transfer, while a web application firewall primarily protects web applications but does not secure data transmission itself.
