Abstract
The rapid development of information technology in the digital era requires a deeper understanding of cybersecurity, particularly for students in the field of information systems. To support the learning process, an interactive medium is needed that not only provides theoretical knowledge but also practical experience. One approach that can be applied is the development of a web-based Capture The Flag (CTF) platform as a learning tool for basic cybersecurity training for students of the Information Systems Study Program at UNUSU. This system was designed and developed using the Waterfall method, which includes the stages of requirements analysis, system design, implementation, testing, and maintenance. The resulting platform offers a variety of basic cybersecurity challenges, an automated scoring system, participant ranking dashboards, and supporting materials to help students understand the concepts before attempting the challenges.
