Universities can exchange information and share data and communicate with the internet network. General Achmad Yani University Yogyakarta (Unjaya) uses the internet network for activities that occur on campus. QoS testing or internet network performance aims to maintain the stability of network access on the Unjaya campus and reduce the risk of problems such as delays in data transmission. In addition, this research also aims to determine the results of signal quality measurements in the Unjaya real-time area. In this research, QoS measurement is done by using wireshark application.&nbsp; The QoS parameters measured are throughput, delay, jitter, and packet loss.&nbsp; Based on the measurements taken, the results obtained for QOS measurements show that WiFi network performance based on throughput, delay, jitter, and packet loss parameters is in the good category. The final result obtained after measuring QoS is that the Internet network at Campus 1 Unjaya is in the medium category based on TIPHON standardization with an index value of 3.</em></p> Isnaini Syarifatun Nisa Nisa Rahmat Miyarno Saputro Tegar Fatwa Nugroho Alfirna Rizqi Lahitani Copyright (c) 2024 Teknomatika: Jurnal Informatika dan Komputer 2024-04-01 2024-04-01 17 1 1 9 10.30989/teknomatika.v17i1.1307 https://ejournal.unjaya.ac.id/index.php/teknomatika/article/view/1330 <p><em>This study examines the security of academic information systems using the COBIT 5 Framework. Key issues are uncertainty in protecting student and staff data, the potential for cyberattack vulnerabilities, and non-compliance with international security standards. The goal is to evaluate the security level of the system and suggest improvement recommendations according to COBIT 5 principles. Research methods include Renstar IT policy analysis, system audits, and interviews with IT personnel and related academic communities. Data is analyzed quantitatively to identify weaknesses and opportunities for improvement. The COBIT 5 framework is used as a security assessment framework. The results highlight the need for improvement, including access management, activity monitoring, and continuous improvement plans. Using COBIT 5, substantial measures such as strengthening access controls and developing disaster recovery plans can be identified. The research emphasizes the importance of a structured approach in improving the security of academic information systems, with COBIT 5 as a useful tool. With the right measures, system security can be enhanced to protect the integrity, confidentiality, and availability of critical data for educational institutions. In conclusion, these measures demonstrate how important COBIT 5 implementation is in addressing information security challenges in academic environments.</em></p> Yonal Supit Edy Irwansyah Copyright (c) 2024 Teknomatika: Jurnal Informatika dan Komputer 2024-04-01 2024-04-01 17 1 10 24 10.30989/teknomatika.v17i1.1330
