The importance of Security in a Crestron Control System

The importance of Security in a Crestron Control System


– Hi, I’m Kevin from A-Knowledge, and today would like to take some time to raise awareness on security of your control system. There are some crawlers out there on the internet that are
scanning public IP addresses 24/7 looking for open ports. As soon an open port is found, the crawler will try to identify the service available
behind this open port. All this information is being gathered in a central database and made available to
users like you and me to just search the database. It’s a search engine for
hackers, Google for hackers. An example of such a
crawler is called Shodan, and Shodan gives you the possibility to use keywords and to try to find available services on the internet. Now the crawler has
identified an open port on this public IP address. It even was able to identify the brand and the device from this control system, which is available on the open port. We’re not interested in
people with bad intentions using the crawler, finding your device, and connecting to it. They could erase the program, they could reboot device, which causes problems for the owner of the control system. So it is really interesting and really important to pay attention to authentication. Enable authentication,
go for a good username with good password to protect your device. Another option is talking
to the network admin. He’ll be able to make sure that your devices will not be exposed to the public internet. Now this raises a very
interesting ethical question. Is one able or is one allowed to use such a crawler and
connect to an unknown device? I’ve found a very interesting example on the internet saying that you can compare it to one walking down the street, going up to each front door and just checking if it is locked or not. Now you will not go in
there if it’s unlocked. You’re just interested
in that information. So whatever you do, just make sure that your devices don’t end up on such a crawler, and make sure that nobody is connecting to your system. Thanks for watching. See you next time.
