The rapid integration of technology in educational institutions has led to the widespread adoption of StudentManagement Information Systems (SMIS) to streamline administrative processes and enhance student experiences.However, these systems are increasingly becoming targets for cyber-attacks due to the sensitive nature of the data theystore, such as personal information, academic records, and financial details. This study evaluates the existingvulnerabilities in university SMIS implementations, focusing on their potential impact on student data security. Througha comprehensive analysis of various university SMIS across different institutions, this research identifies commonsecurity flaws, including inadequate access controls, outdated software, lack of encryption, and improper data handlingpractices. Additionally, the study highlights the implications of these vulnerabilities, such as unauthorized data access,data breaches, identity theft, and potential reputational damage to institutions. By examining these risks, the studyprovides a framework for understanding the critical areas that require immediate attention and offers recommendationsfor enhancing the security posture of university SMIS. The findings aim to guide universities in developing robustsecurity measures to protect student data, ensuring the privacy and integrity of their academic environments.
