Abstract

PT.XYZ is a CRM solutions provider that helps businesses manage their interactions with customers. Through in-depth research, a security vulnerability was discovered on PT.XYZ's platform that could be exploited by unauthorized parties to escalate their access rights unlawfully. This research involved a comprehensive analysis of CRM system. The research method included application analysis, exploitation, impact evaluation, solution development, and reporting. The findings revealed a vulnerability in the user management mechanism, allowing a regular user to escalate their access rights to an administrator level. This could potentially lead to customer data misuse, operational disruptions, and financial losses for the company. The research process involved penetration testing, impact analysis, and the development of mitigation solutions. Thanks to these findings, PT.XYZ has implemented system improvements to address the security gap. This research demonstrates the importance of conducting regular security testing to ensure a company's information systems remain protected from cyber threats.

Abstract

The rapid growth and advancement of digital technology have encouraged educational institutions to adopt information systems to support academic processes. Universitas Advent Indonesia (UNAI) has implemented an Academic Information System and a Learning Management System (LMS) as part of its digital transformation in educational services. This study aims to evaluate the level of cybersecurity risk and maturity in the university’s academic information system using the National Institute of Standards and Technology (NIST) framework. Risk analysis was conducted using NIST SP 800-30 to identify, analyze, and evaluate potential threats and vulnerabilities. The effectiveness of security controls was assessed based on NIST SP 800-53A, while the Capability Maturity Model Integration (CMMI) was applied to measure the maturity level of information security implementation. The study employed two instruments: (1) a security awareness questionnaire for structural respondents to assess their perception and understanding of information security, and (2) a security control audit for technical respondents to evaluate the actual implementation of security measures. The collected data were processed using a descriptive–quantitative method and converted into maturity levels according to the CMMI model. The results show that the structural group obtained an average score of 3.94, corresponding to Level 4 (Quantitatively Managed), indicating that security controls have been implemented consistently and measured effectively. The technical group achieved an average score of 3.60, corresponding to Level 3 (Defined), suggesting that security processes are standardized but not yet fully based on quantitative measurement. According to the NIST SP 800-30 framework, most security controls are categorized as implemented and partially implemented. These findings indicate that UNAI’s cybersecurity maturity level is generally strong but still requires improvement in policy documentation, supervision, and security training to achieve the optimal maturity level.

Abstract

The rapid development of information affects many aspects of human life. So that the field of information security becomes one aspect that must be considered. This study aims to measure the information security awareness and to improve daily operational activities of managing IT services effectively and efficiently. Salemba Adventist Academy has used the Wium Online Education Management System (WIOEM) online system, but in its implementation the security aspects of the system are not yet known. The Information Technology Infrastructure Library (ITIL) v3 framework which is globally recognized for managing information technology is broken down into five parts: Service Strategy, Service Design, Service Transition, Service Operation, Continual Service Improvement. This study focuses on Service Operations with 4 attributes, namely: Security, Privacy, Risk, and Trust. The data collection method used by the researcher was through observation in the form of a questionnaire in taking the number of samples to several students by taking population samples using the Lemeshow method. After the data were collected, the results of the ITIL indicator questionnaire are calculated based on the data security level. The results show that the Security indicator is Level 1, the Privacy indicator is level 3, the Risk indicator is level 3, and the Trust indicator is level 4 on the Data Security Level scale. This shows that the WIOEM system can be used properly according to user expectations and meets several levels of data security according to ITIL v3 framework.
