Which of the following Linux server roles should be installed to monitor and log local web traffic?

A proxy server such as Squid sits between clients and destination web servers, forwarding requests while simultaneously monitoring and logging all HTTP and HTTPS traffic passing through it. This is the standard Linux role deployed when visibility into web traffic patterns, URLs visited, bandwidth usage, or access control violations is required.

An AAA server handles authentication, authorization, and accounting for user identity management, not the inspection or logging of web traffic content.

An SSH server provides encrypted remote shell access to a system and does not intercept, monitor, or log web traffic between clients and servers.

An HTTP server serves web content to requesting clients but does not act as an intermediary or log traffic flowing between other clients and external servers.

A name server (DNS) resolves hostnames to IP addresses and does not monitor or log web traffic payloads or sessions.
