Abstract

In the era of massive digital information exchange, data security has evolved from mere encryption to the need for confidentiality regarding the existence of the data itself. This research report presents an in-depth analysis, design, and evaluation of SteganoID, a web-based steganography application developed to fulfill the requirements of the Cryptography and Steganography course at Universitas Malikussaleh (UNIMAL). The application integrates the Advanced Encryption Standard (AES) cryptographic algorithm with Least Significant Bit (LSB) steganography techniques and file structure modifications for image, audio, and PDF document media. This study explores the effectiveness of a hybrid approach in securing the text message "UNIMAL HEBAT" within the xrank.pdf file, as demonstrated in system testing. By leveraging client-side processing capabilities through modern JavaScript and HTML5 APIs, SteganoID offers a portable security solution without requiring software installation, mitigating privacy risks associated with server-side processing. This report comprehensively outlines the theoretical foundation, system architecture, interface implementation, and analysis of robustness against steganalysis attacks.

Abstract

Evolusi ancaman siber yang pesat telah mengubah virus komputer sederhana menjadi entitas yang sangat canggih, seperti malware polimorfik dan serangan tanpa file (fileless). Penelitian ini bertujuan untuk memberikan analisis mendalam mengenai mekanisme pertahanan internal pada sistem operasi (OS) modern. Metodologi penelitian melibatkan evaluasi teknis terhadap beberapa lapis perlindungan, termasuk integritas memori, keamanan berbasis virtualisasi, dan integrasi algoritma pembelajaran mesin untuk deteksi perilaku. Hasil penelitian menunjukkan bahwa meskipun deteksi berbasis tanda tangan (signature) tradisional mulai usang, kombinasi antara keamanan berbasis perangkat keras (TPM) dan analisis heuristik dinamis menawarkan perlindungan yang kokoh terhadap eksploitasi zero-day. Penelitian ini menyimpulkan bahwa sinergi antara isolasi tingkat kernel dan kecerdasan berbasis awan (cloud) sangat penting untuk menjaga integritas sistem di era ancaman yang terus berkembang secara persisten
