As part of the Department of Cybersecurity Engineering Technologies' efforts to strengthen students' practical skills and connect theoretical concepts with technical applications, a practical session entitled "Data Processing" was conducted as part of the Linux Fundamentals course. The session covered the use and execution of various commands in the Kali Linux operating system, with particular emphasis on combining two or more commands into a single command using the Terminal command-line interface. It also introduced students to different methods of organizing command execution and processing data efficiently. This practical activity aims to develop students' skills in working with the Linux environment and enhance their ability to use essential commands and tools that form an important foundation for cybersecurity professionals. The activity aligns with the Sustainable Development Goals, particularly SDG 4 (Quality Education) and SDG 9 (Industry, Innovation and Infrastructure).
