CertNexus Certified Cyber Secure Coder (CSC) — Question 49

An organization recently suffered a data breach involving a server that had Transmission Control Protocol (TCP) port 1433 inadvertently exposed to the Internet. Which of the following services was vulnerable?

Answer options

• A. Internet Message Access Protocol (IMAP)
• B. Network Basic Input/Output System (NetBIOS)
• C. Database
• D. Network Time Protocol (NTP)

Correct answer: C

Explanation

The correct answer is C, as TCP port 1433 is commonly associated with Microsoft SQL Server, which is a database service. The other options, such as IMAP, NetBIOS, and NTP, use different ports and are not related to TCP port 1433.
