The communication uses port 443 and the HTTPS protocol. - Agents on endpoint systems do not need any special ports open to communicate with the SysTrack master. - If there is more than one master system, TCP ports 57632 and 57633 must be open between masters. - SysTrack Deploy communicates with the master system using TCP port 57632. - Inter-process communication takes place on the master system using TCP port 57633. - If Microsoft 365 integration with SysTrack is enabled, access to the following Microsoft internet services is required: - [https://graph.microsoft.com](https://graph.microsoft.com/) - [https://login.microsoftonline.com](https://login.microsoftonline.com/) ![](https://cdn.document360.io/87d11426-6b1f-4b19-b593-b71e55a81af3/Images/Documentation/endpoint_system.png) ## Network Traffic - Default port for agent communication: 443 - Average network usage per device: ~2.3 MB per day - If databases are sent back to the master (caching), this will add an average of approximately 30mb per system, a minimum of once a day. This can also occur each time a system goes offline (logout/shutdown). ## Authentication Options - NTLM - Kerberos (may require port 88 for KOC communications) - Negotiate (uses NTLM/Kerberos) - S-Channel (all machines need certificates) - Anonymous (none)
