External connection to 1C cluster manager ports 1541/1570-1571
Detects outbound network connections made by 1C Enterprise processes (rmngr.exe or rphost.exe) to non-private/external IP addresses over specific ports (1541, 1570, 1571). These processes typically handle database server management and application host functions within the 1C platform, and direct external communication from them may indicate unauthorized activity or C2 traffic.
