Abstract

This research aims to implement Security Information and Event Management (SIEM) in the Kuningan University academic system. The security of information systems in the educational environment, especially in university academic systems, is becoming increasingly important considering the availability of sensitive data, such as student personal information and academic data which must be properly protected. Security threats such as cyber attacks are increasingly complex and can often be detrimental to both universities and system users. In this research, we apply SIEM as a solution to detect, prevent and respond to security threats to the Kuningan University academic system. The system development method is used with the steps of system requirements analysis, system design, system implementation, system testing, and system evaluation. The output of this research is an increase in the security level of Kuningan University's academic system. By implementing SIEM, the system is expected to be able to quickly and effectively detect potential security threats, improve response to security events, and provide reports that are useful for making decisions. Thus, it is hoped that the results of this research can make a significant contribution in improving security and data protection in the Kuningan University academic system, as well as becoming a reference for other educational institutions in maintaining increasingly complex information security defenses.

Abstract

Web Services merupakan suatu sistem perangkat lunak yang menyediakan antarmuka untuk mengakses sekumpulan data maupun layanan yang tersimpan dalam basis data melalui jaringan internet. Pada kondisi standarnya, web services tidak dilengkapi dengan mekanisme keamanan yang memadai untuk melindungi akses data. Meskipun sebagian implementasi web services telah menggunakan JSON Web Token (JWT) sebagai lapisan keamanan autentikasi dengan algoritma HS256 berbasis SHA256, algoritma tersebut diketahui memiliki celah keamanan berupa serangan Preimage Attack dalam Pseudo Collision yang dapat mengancam integritas data. Serangan Preimage menargetkan fungsi hash kriptografi dengan tujuan menemukan pesan yang menghasilkan nilai hash tertentu, sehingga kerahasiaan token dapat terancam. Untuk mengatasi kelemahan tersebut, diperlukan penerapan algoritma hash yang lebih kuat sebagai pengganti SHA256 pada JWT. Algoritma Tiger Hash dipilih sebagai solusi karena mampu memproses pesan dalam blok berukuran 512 bit dan menghasilkan message digest berukuran 192 bit. Tiger Hash bekerja melalui 24 putaran yang terbagi dalam tiga pass, masing-masing terdiri dari delapan putaran dalam, dengan memanfaatkan operasi XOR, penambahan atau pengurangan, rotasi, serta pencarian S-boxes. Hasil akhir penelitian ini adalah sebuah web services yang mengintegrasikan algoritma Tiger Hash sebagai mekanisme pengamanan komunikasi data.
