Protocol Information

BACnet je protokol komunikacije za mreže automatizacije i kontrole zgrada (BAC) koji koristi ASHRAE, ANSI i ISO 16484-5 standard protokol. Omogućava komunikaciju među sistemima automatizacije i kontrole zgrada, omogućavajući aplikacijama kao što su kontrola HVAC-a, kontrola osvetljenja, kontrola pristupa i sistemi za detekciju požara da razmenjuju informacije. BACnet osigurava interoperabilnost i omogućava računarima automatizovane uređaje zgrada da komuniciraju, bez obzira na specifične usluge koje pružaju.

Enumeracija

Ručno

pip3 install BAC0
pip3 install netifaces

import BAC0
import time

myIP = '<Your IP>/<MASK>' #You need to be on the same subnet as the bacnet device. Example: '192.168.1.4/24'
bacnet = BAC0.connect(ip=myIP)
bacnet.whois() #Broadcast request of bacnet devices
time.sleep(5)  #Wait for devices to respond
for i, (deviceId, companyId, devIp, numDeviceId) in enumerate(bacnet.devices):
print(f"-------- Device #{numDeviceId} --------")
print(f"Device:     {deviceId}")
print(f"IP:         {devIp}")
print(f"Company:    {companyId}")
readDevice = bacnet.readMultiple(f"{devIp} device {numDeviceId} all")
print(f"Model Name: {readDevice[11]}")
print(f"Version:    {readDevice[2]}")
# print(readDevice) #List all available info about the device

Automatski

nmap --script bacnet-info --script-args full=yes -sU -n -sV -p 47808 <IP>

Ovaj skript ne pokušava da se pridruži BACnet mreži kao strana uređaj, već jednostavno šalje BACnet zahteve direktno na uređaj koji ima IP adresu.
