On most long-running Linux servers, UFW rules don't get removed; they get forgotten. Services change, ports shift, packages come and go, and the firewall stops matching what the box is actually doing. You only notice when you audit it, or when something breaks and nobody remembers why a port was ever opened.

Tor Browser is a privacy-focused web browser that routes traffic through the Tor network to obscure a user's identity and destination''and that design has direct implications for Linux security teams. It's built to limit tracking, resist surveillance, and reduce visibility into browsing activity. On a Linux endpoint, that means user activity can intentionally bypass many of the controls and assumptions your security stack relies on.

UFW looks simple until you put it on a long-lived server and real traffic hits it. This focuses on the gap between what ufw status shows and what packets are actually doing on production hosts, after rules have already been set up and systems have been up for a while.
