Technical Details
what runs on :7312The Sibelius License Server is a specialized network service designed to handle the distribution and management of floating licenses for Avid Sibelius software within educational or enterprise environments. By utilizing this server, administrators can maintain centralized control, ensuring license compliance and efficient allocation to authorized users.
Typically, the Sibelius License Server operates over UDP port 7312, which enables it to listen for incoming license requests from Sibelius client installations on the network. The clients periodically communicate with the server during launch and use to verify license validity, and to release licenses upon closing, allowing other users to access them.
The server infrastructure allows for scalable license deployment, enabling concurrent connections up to the license pool limit. It integrates seamlessly with the Sibelius client and supports features like reservation of licenses for specific devices or user groups, as well as license borrowing in offline scenarios, depending on configuration.

security overview
Common vulnerabilities:
- Since it operates over UDP, it is susceptible to spoofing or replay attacks if no additional security measures are in place.
- Exposure to untrusted networks could allow unauthorized license use or denial-of-service by flooding the server with requests.
- Potential for information disclosure or unauthorized access if the service is deployed without network segmentation or access controls.
Common mitigations:
- Restrict access to UDP port 7312 using firewalls and network access controls so only trusted internal clients can communicate.
- Employ VPNs or secure tunnels to protect communication if remote clients access the server.
- Regularly update server software to patch known vulnerabilities and monitor for unusual behavior.
- Segment license server on a secure management network separate from guest or external networks.
