IT vs. OT - What is OT and how is it different from IT

 

IT vs. OT

 In this video, James Cabe and Anthony Bartolo as they discuss how Microsoft is approaching cybersecurity for Industry 4.0 using Azure Defender for IoT, including:

  • learn about the differences between Operational Technology (OT) and Industrial Control Systems (ICS)
  • gain an understanding of how this compares to the modern Internet of Things (IoT)
  • the challenges of securing OT networks
  •  how ladder logic can cause cascading impacts
  •  how to use the Purdue model to help with communications between the IT and OT security teams as they build a cohesive end-to-end protection solution for modern cyber attacks

Problem with an old IoT (RaspberryPi)

One problem when we work on the old raspberry pi is, we can hardly remember all the pinouts on those old model. I've an old Raspberry Pi that is an old model B with 512mb. 

And I'm try to find the power and the ground pins. When I turn to Google, most of the GPIO pinout is either for RPi4 or Rpi3.

At last, I found a way to solve my problem. 
 
First, I install a python package python-gpiozero (or python3-gpiozero). 
 
$ sudo apt install python-gpiozero
 
Then I run the command "pinout", as below, and I found the right pins (4/6) for me. ;)

IoT/Embedded Device Hacking Training

Just finished attending the IoT/Embedded Device Hacking 5-day Training (Dec 18~22).

This training course is designed to help people working in the information security industry to learn basic knowledge needed to hack and reverse-engineer embedded system. The training covers embedded device hacking with UART/JTAG, dumping/parsing/extracting/analyzing firmware image, modifying firmware, detecting/analyzing embedded malware, discovering/exploiting vulnerabilities in firmware, and wireless hacking using SDR.

Course Outline:

  • Module 1: Hunting for UART ports
  • Module 2: Hacking Embedded Device with JTAG
  • Module 3: Firmware Acquisition
  • Module 4:  Basics of Reverse Engineering ARM/MIPS Code
  • Module 5:  Embedded Device Vulnerability Assessment
  • Module 6:  Embedded Malware Detection and Analysis
  • Module 7:  Modifying Firmware for Fun and Profit
  • Module 8:  Hacking Wireless Network
