IoT News: Senators securing IoT

 

Hi there! Welcome to your weekly roundup of IoT news. My name’s Natalie, and I’m a newbie to the Internet of Things and smart buildings. I don’t have a tech degree, and Wireshark’s a mystery to me. But I do have a fresh perspective that you won’t see from 20-year (or more) veterans of the field.

Five ways to securely analyze BACnet data

 

You’ve spotted a problem on your BACnet network. Devices are dropping like flies, with no apparent explanation. You need to get a packet capture (pcap) if you want to dig in and untangle what’s happening. But the IT department’s worried what sensitive information could be leaked if you pull any data. You’re at a stand-off, with conflicting needs.

 

Trying to convince your IT department that you can safely pull pcap files? Here are five ways to keep IT out of your OT.

How to find and solve duplicate networks

 

Controllers are offline. You try resetting your BACnet router to get them back on. It works, and the controllers come online… But then the controllers off of a different router go offline, and you have to solve the problem all over again.

If you feel like you’re juggling to keep all your BACnet devices online, a duplicate network might be the culprit. We’re here to help you figure out how it happens and what you can do to fix it.

Addressing Cybersecurity Concerns in Building Automation Systems

 

Forget the common wisdom about cybersecurity

 

Security is not about making the network 100 percent impenetrable. In fact, it is unlikely that any system in the world is completely secure. Hacking is an attack of opportunity, and if criminals see a way into a building, they will take advantage. But if sufficient obstacles are in place to deter them, they will likely look elsewhere for an easier mark.

IoT News: The security app that might never exist

Secure your packet captures

 

Your OT network’s acting funny, and you have no idea why. You need to get a packet capture (pcap) and upload it into Visual BACnet, but the IT department’s dead-set against it: they won’t let you upload unless you scrub the files of confidential information, so they can’t be traced back to the building.

If your IT department doesn’t like you pulling pcaps to analyze BACnet health, your best bet is to anonymize the files. Changing the IP and MAC addresses will get rid of any identifying information. Then, you can dig into pcaps, troubleshoot, and solve problems with ease.

Report on network health with Visual BACnet

 

Maybe you’re on a site for maintenance, a service call, or to install a new device. You’re making a bunch of big changes that will affect the BACnet network. You need to show the client that the changes you made have helped — or at least, haven’t hurt — the network. But how do you give concrete proof? Where do you even get this proof?
