Inject Stenography into Cybersecurity Education

Along with the development of information security, steganography has received increasingly attention. It has become a trend that more and more institutions offer steganography techniques in cybersecurity education. In this paper, we propose integrating steganography into cybersecurity curriculum. Stenography modules and hands-on labs are designed. It covers the principles of steganography, steganographic techniques, and the basis of steganalysis. Three lab exercises include steganography implementation in HTML, TCP/IP, and digital image.
