Internet Small Computer System Interface (iSCSI) merupakan protokol yang berjalan di lapisan transport pada jaringan TCP/IP yang bekerja untuk mengirimkan perintah-perintah SCSI agar memungkinkan suatu komputer dapat mengakses block-level dari media penyimpanan pada komputer yang berbeda. Selain digunakan pada jaringan LAN, MAN ataupun MAN, iSCSI juga dapat digunakan pada jaringan virtual yang menghubungkan mesin virtual dan mesin yang secara fisik memang ada atau nyata. Pada penelitian ini, dilakukan pengujian terhadap kinerja dari iSCSI pada jaringan virtual yang menghubungkan mesin virtual dan mesin nyata agar mendapatkan nilai throughput dan kecapatan baca/tulis untuk kemudian dianalisa lebih lanjut.

A Sense-based Registration Process for TDMA in IEEE 802.11 Network Rizal Fathoni Aji; Heru Suhartanto; Setiadi Yazid
International Journal of Electrical and Computer Engineering (IJECE) Vol 8, No 1: February 2018
Publisher : Institute of Advanced Engineering and Science

TDMA implementation offer better fairness and throughput in IEEE 802.11. To implement TDMA, new registration process is needed, because current registration mechanism can disrupt TDMA process. This paper proposes a sense-based TDMA registration process using service slot and random timer. Simulation result shows, by using our mechanism, we can reduce the number of unused timeslot, and for 10 new nodes, each node only need 7 ms to complete the registration process.

Kepadatan trafik data pada jaringan menyebabkan timbulnya kemacetan atau congestion pada lalu lintas trafik data. Jika terjadi di jaringan internet publik, kondisi ini akan mengganggu kenyamanan pengguna. Seringkali kepadatan ini disebabkan oleh pengguna yang melakukan pengunduhan data dalam jumlah besar. Solusi yang sering digunakan untuk mengurangi kepadatan trafik ini adalah dengan memperbesar bandwidth atau menggunakan metode seperti traffic policing serta queue management. Permasalahannya, solusi ini sulit diterapkan untuk organisasi skala kecil seperti sekolah atau pemerintahan desa yang tidak memiliki sumber dana yang besar untuk teknologi ini. Penelitian ini bertujuan untuk memodifikasi perangkat lunak sumber terbuka bernama Tuxcut untuk dimanfaatkan sebagai teknik pembatasan bandwidth dengan biaya murah. Dari hasil penelitian, didapatkan bahwa penerapan modifikasi perangkat lunak ini dapat digunakan untuk membatasi penggunaan bandwidth.

Jurnal Ilmu Komputer dan Informasi Vol 6, No 2 (2013): Jurnal Ilmu Komputer dan Informasi (Journal of Computer Science and Information)
Publisher : Faculty of Computer Science - Universitas Indonesia

In this study we discuss how to handle DDoS attack that coming from the attacker by using detection method and handling mechanism. Detection perform by comparing number of packets and number of flow. Whereas handling mechanism perform by limiting or drop the packets that detected as a DDoS attack. The study begins with simulation on real network, which aims to get the real traffic data. Then, dump traffic data obtained from the simulation used for detection method on our prototype system called DASHM (DDoS Attack Simulation and Handling Mechanism). From the result of experiment that has been conducted, the proposed method successfully detect DDoS attack and handle the incoming packet sent by attacker.

Ransomware is the most prevalent emerging business risk nowadays. It seriously affects business continuity and operations. According to Deloitte Cyber Security Landscape 2022, up to 4000 ransomware attacks occur daily, while the average number of days an organization takes to identify a breach is 191. Sophisticated cyber-attacks such as ransomware typically must go through multiple consecutive phases (initial foothold, network propagation, and action on objectives) before accomplishing its final objective. This study analyzed decoy-based solutions as an approach (detection, prevention, or mitigation) to overcome ransomware. A systematic literature review was conducted, in which the result has shown that deception-based techniques have given effective and significant performance against ransomware with minimal resources. It is also identified that contrary to general belief, deception techniques mainly involved in passive approaches (i.e., prevention, detection) possess other active capabilities such as ransomware traceback and obstruction (thwarting), file decryption, and decryption key recovery. Based on the literature review, several evaluation methods are also analyzed to measure the effectiveness of these deception-based techniques during the implementation process.

The development of e-government is increasingly prioritized in developing countries as part of digital transformation efforts to improve the quality of public services. However, challenges such as low adoption rates, public trust issues, and weak information security persist. This research aims to comprehensively identify information security factors influencing e-government adoption in developing countries and propose implementation strategies. The approach used is a combination of systematic literature review and snowballing technique. We categorized security factors using the Technology, Organization, and Environment (TOE) framework to aid analysis and strategy formulation. Findings show that non-technical factors, particularly organizational and environmental aspects (41% each), dominate over technical factors (18%). These results highlight the importance of strengthening security policies, risk management, and data protection regulations by the government, as well as efforts to improve public perception of information security. This research provides theoretical contributions through a TOE-based framework and practical strategies to increase e-government adoption.
