Digital Technologies and Security introduces students to the foundational concepts of web and mobile application development with a focus on client-side and server-side technologies. Students will explore modern frameworks, tools, and programming languages used in front-end and back-end development, gaining practical skills in building interactive, secure digital applications. The subject covers HTML, CSS, JavaScript, and server-side scripting, along with mobile app development principles across platforms. Emphasis is placed on secure coding practices, authentication, data protection, and threat mitigation. Students will critically examine how security must be integrated throughout the software development lifecycle to protect users, systems, and data. Through project-based learning, students will design, develop, and evaluate secure digital solutions while considering ethical and legal aspects of cybersecurity. This subject prepares students for real-world roles in digital systems development by combining technical development skills with a deep understanding of security in today’s connected environments.
