What This Port Does
Port 3192 is registered with IANA under the service name firemonrcc — FireMon Revision Control. It belongs to FireMon Security Manager, a network security policy management platform used by enterprises to audit, analyze, and track changes to firewall rulesets across their infrastructure.
The revision control component does exactly what the name implies: it records configuration snapshots from managed firewalls, detects when rules change, and maintains a history of those changes. Port 3192 is the channel through which this revision data flows.
The Range It Belongs To
Port 3192 sits in the registered ports range (1024–49151). These ports require a formal application to IANA but are not reserved for system-level services the way well-known ports (0–1023) are. Any process can bind to a registered port, but the assignment signals "this is what we intend it for."
The registration contact was Michael Bishop at fishnetsecurity.com — FishNet Security, the company that built FireMon as an internal auditing tool before spinning it off as a standalone product.
Who Actually Uses This Port
This is specialized enterprise infrastructure. You will encounter port 3192 in environments where:
- Security teams need to prove compliance with change management policies
- Network operations centers must detect unauthorized firewall modifications
- Auditors need to answer questions like "what did this rule look like 90 days ago?"
Outside enterprise security management deployments, port 3192 carries no traffic. It is not commonly probed, exploited, or repurposed.
Checking What's Listening
To see if anything is using port 3192 on your system:
Linux / macOS:
Windows:
If nothing is returned, nothing is listening. If you see a process and you are not running FireMon, investigate — any unexpected listener on a registered port is worth understanding.
Why Unassigned and Lightly-Used Ports Matter
The registered port space contains thousands of entries like this one: real assignments for real products that most of the Internet will never encounter. They matter for a few reasons.
First, they establish expectations. If your network scanner flags port 3192 as open on a server, knowing the IANA assignment tells you immediately what software is probably running there — and whether it should be.
Second, they prevent collisions. Without the registry, two products might independently choose the same port, creating conflicts when both are deployed together. The assignment is a claim on a number.
Third, they create a record of the software ecosystem at a given moment. Port 3192 was registered when FireMon was mature enough to need a permanent home. The port number is a timestamp of sorts.
