I am pretty sure HTTP(s) is the right choice
The choice of HTTPS does complicate the network infrastructure moving log
records into a "network management" QoS class (ie, making sure that remote
logging works during a DoS attack caused by malware).
If you feel that HTTPS is the correct protocol then please consider using
another port number than 443.
