Which of the following data source will a SOC Analyst use to monitor connections to...

A SOC Analyst would use Netstat Data to monitor connections to insecure ports. Netstat, which stands for network statistics, is a command-line tool that displays incoming and outgoing network connections (both TCP and UDP), routing tables, and a number of network interface and network protocol statistics. It is available on various operating systems, including Windows, Linux, and Unix, and is used for finding problems in the network and to determine the amount of traffic on the network as a performance measurement.

References: The use of Netstat for monitoring network connections is a common practice and is covered in EC-Council’s SOC Analyst curriculum, which provides foundational knowledge for security operations center (SOC) team members on various tools and techniques for monitoring and analyzing network traffic12. Additionally, Netstat’s capabilities are well-documented in various technical resources that detail its usage for security analysis purposes34.
