Which of the following tools would a security administrator use in order to identify all running services throughout an organization?

The correct answer is C. Port scanner. A port scanner (e.g., Nmap) probes hosts across the network to discover which TCP/UDP ports are open. Because each open port corresponds to a listening service, a port scanner is the standard tool for inventorying all running services organization-wide. An architectural review ex

Explanation

A port scanner (e.g., Nmap) probes hosts across the network to discover which TCP/UDP ports are open. Because each open port corresponds to a listening service, a port scanner is the standard tool for inventorying all running services organization-wide. An architectural review examines system design documents. A penetration test goes further by actively exploiting vulnerabilities. A design review evaluates plans. Port scanning is the direct, automated way to enumerate live services across many hosts simultaneously.
