Securing the BMS of a Lagos office tower: asset inventory, zones and conduits, risk register and BACnet/SC migration plan
Assess and secure the building management system of a 14-storey office tower, as the BMS security engineer. List every connected asset, draw the zones and conduits, and register the risks. Plan the hardening, the remote access changes and the move to BACnet/SC, and write the evidence note for the tenant. Work from drawings and your own bench equipment, and never scan or change a live building without the owner's written permission.

Tools
Software, hardware and lessons
Software
None required. Wireshark (free) is useful for looking at BACnet traffic on a test network you own.
Hardware
None. A spare BACnet controller on a bench network makes the hardening exercises more real.
Who it is for
Intermediate. You should know what a BMS does and have basic networking knowledge: IP addresses, subnets and VLANs. Experience with BACnet or Modbus helps but is not required.

Practise what you learn in the free 3D lab
Technical work is judged on what you can do: wiring, commissioning, finding a fault. Doing a task yourself teaches more than watching it a second time, and a lab lets you try it safely before you meet real equipment. It does not replace working on real hardware.
- Practise safely, so a mistake costs nothing.
- The lab checks your work like a site test, so you know when it is right.
- Free, in your browser, with nothing to install.
Why learn with EDWartens
What you get with this course.
- Free from the first lesson to the final assessment.
- Practice in a free 3D lab in your browser, with nothing to install.
- Video lessons with written notes and a project.
- An optional certificate that anyone can verify online.
FAQ
Common questions
Who is the Cybersecurity for Building Automation: BMS and BACnet course for?
BMS engineers and technicians, system integrators, facility managers, MEP consultants and OT or IT security staff who look after building systems. Basic networking knowledge is assumed.
Is this a hacking course?
No. It teaches people responsible for buildings to protect them. There are no techniques for attacking systems, and the course warns against testing live buildings without written permission.
Is it tied to one BMS vendor?
No. It is about BACnet, Modbus and the design of any BMS. Siemens and other companies' lessons are used where they explain the ideas well, credited on each module, and none of them is affiliated with EDWartens.
Do I need BACnet/SC equipment?
No. The course explains BACnet/SC from the lessons and the standard's principles. If you have a controller that supports it, the bench exercises become more real.
Is the Cybersecurity for Building Automation: BMS and BACnet course really free?
Yes. Every module, the notes, the project and the final assessment. The only paid item is the certificate, if you want it.
What certificate does the Cybersecurity for Building Automation: BMS and BACnet course give?
An EDWartens Certificate of Completion, issued when you pass the final assessment, with a number anyone can verify on our site. It is not a BACnet International or ASHRAE certification.
How long does the Cybersecurity for Building Automation: BMS and BACnet course take?
About 8.1 hours of video lessons, notes and practice questions, plus about 10 hours if you do the project. At an hour a day, that is about two and a half weeks.
What is the project in the Cybersecurity for Building Automation: BMS and BACnet course?
You assess the BMS of a 14-storey office tower in Lagos, Nigeria, whose tenant wants evidence that the building's systems are secure. You write an asset inventory, a zones and conduits model, a risk register, and a plan for hardening, vendor remote access and a phased move to BACnet/SC.
Do I have to use the lab?
No. The lab is optional practice. You can skip it whenever you like, and it never blocks your progress, the final assessment or your certificate.
Is the lab free?
Yes. Every lab level for this course opens in your browser, free, with nothing to install.
Is the Cybersecurity for Building Automation: BMS and BACnet course free in India, and what does the certificate cost?
Yes. Learning costs ₹0 in India: every module, the written notes, the practice tasks and the final assessment, with no card and no trial period. The only paid item is the optional EDWartens Certificate of Completion, ₹599 including GST for this intermediate course, paid in rupees through Razorpay, and only if you want it after passing the final assessment.
What topics does the Cybersecurity for Building Automation: BMS and BACnet course cover, module by module?
The Cybersecurity for Building Automation: BMS and BACnet course has 9 modules. It opens with "Buildings that got hacked", goes through "How a BMS network is built, and where it is weak", "Designing a secure building management system", "Securing BACnet systems in depth" and "Where BACnet security is going" and ends with "Final Assessment". The full list with minutes is under "What you learn" on this page.
What can I do after the Cybersecurity for Building Automation: BMS and BACnet course?
After the Cybersecurity for Building Automation: BMS and BACnet course: Explain how buildings have been hacked and why a BMS can be a way into the business; Describe BMS architecture and find the weak points in BACnet, Modbus and MS/TP networks; Harden controllers, servers and accounts in the building's priorities. These are the practical outcomes the course is written around, and the final assessment of 15 questions checks them.
What software and hardware do I need for the Cybersecurity for Building Automation: BMS and BACnet course, and does it cost anything?
For the Cybersecurity for Building Automation: BMS and BACnet course, software: None required. Wireshark (free) is useful for looking at BACnet traffic on a test network you own. Hardware: none. A spare BACnet controller on a bench network makes the hardening exercises more real. The course itself is free.
Is the Cybersecurity for Building Automation: BMS and BACnet course suitable for me, and what level is it?
Cybersecurity for Building Automation: BMS and BACnet is rated intermediate. Intermediate. You should know what a BMS does and have basic networking knowledge: IP addresses, subnets and VLANs. Experience with BACnet or Modbus helps but is not required. It is written for BMS engineers, facility managers and integrators, and has 5h 11m of video lessons at your own pace.
Which jobs use the skills from the Cybersecurity for Building Automation: BMS and BACnet course?
Skills from the Cybersecurity for Building Automation: BMS and BACnet course (for example: explain how buildings have been hacked and why a BMS can be a way into the business) are used in OT security engineer work. The course gives you practical evidence of the skill; it does not promise a job, and employers decide on experience and interview.
