CompTIA Security+ Question C-72

Which of the following would a security administrator implement in order to identify a problem between two applications that are not communicating properly?

A. Protocol analyzer
B. Baseline report
C. Risk assessment
D. Vulnerability scan

Answer: A

A Protocol Analyzer is a hardware device or more commonly a software program used to capture

network data communications sent between devices on a network. Capturing and analyzing the packets sent between applications on systems that are not communicating properly could help determine the cause of the issue. Well known software protocol analyzers include Message Analyzer (formerly Network Monitor) from Microsoft and Wireshark (formerly Ethereal).
