What This Port Is
Port 2768 sits in the registered ports range (1024–49151). These are ports that individuals and organizations can formally claim through IANA — and someone did. The IANA registry lists port 2768 as UACS, registered by Vishwas Lele at Applied Information Sciences.1
That is essentially all that is publicly known.
There is no RFC for UACS. No protocol specification. No public documentation explaining what it stands for or what it does. Applied Information Sciences is a real company — a technology consulting firm based in the Washington, D.C. area — but UACS does not appear in any of their public materials. It was registered for something. What that something is remains private.
What "Registered" Actually Means
IANA registration does not mean a port is widely used, well-documented, or even actively deployed. The registered port range exists so that organizations can stake out a number for their software without colliding with someone else. The bar for registration is low: fill out a form, provide a contact, describe your service.
Thousands of registered ports are like this one — a name and an assignee, nothing more. Some represent internal enterprise software. Some represent products that never shipped. Some represent protocols that were deployed, worked fine for years, and were retired without anyone updating the registry.2
Port 2768 could be any of these. Without public documentation, there is no way to know.
Checking What Is Using This Port
If port 2768 shows up on your system, use the appropriate command to identify what process opened it:
macOS / Linux:
Windows:
Then cross-reference the PID (process ID) in Task Manager or tasklist to find the owning process.
An open port is not automatically a problem. If you recognize the application using it, you are done. If you do not recognize it, investigate further.
