Abstract

This study aims to detect intruders on a server computer used for Open Journal System (OJS) services. The server is connected to the internet via a router, making it vulnerable to external attacks. In this research, the tool used is Tripwire, installed on the server computer as the main object. Tripwire functions as a change detection tool for the file system, identifying suspicious activities and recording valid file hashes, verifying file integrity against this record periodically. The system is operated by journal managers from computers connected to the server within the same network address providing OJS services. The method used in this research is the Network Forensic Development Life Cycle (NFDLC), which consists of several stages: initiation, acquisition, implementation, operation, and disposition. Each stage is applied systematically to facilitate the forensic analysis of attacks. The research results show that the NFDLC method is effective in analyzing and detecting intruders in the network. Based on forensic analysis using Tripwire, 12 data losses were found in 7 attack incidents identified on the OJS service. This study successfully demonstrates that the NFDLC method and Tripwire tool are effective in detecting and analyzing intruders attempting to access the OJS service server computer.

Abstract

The rapid development of object detection technology has opened new opportunities in the healthcare sector, especially in early cancer detection. This paper presents a deep learning-based breast cancer detection system using ultrasound images. The primary goal of this study is to create a model that can effectively differentiate between malignant and benign breast tumors, assisting in early diagnosis. The proposed system employs the Convolutional Neural Network (CNN) algorithm with You Only Look Once version 5 (YOLOv5) architecture, which is renowned for its high speed and accuracy in object detection tasks. A dataset comprising 10,954 ultrasound images was used to train the model, with 70% allocated for training, 20% for validation, and 10% for testing. The study reveals that the model achieves a high accuracy rate of 92.8% for malignant tumor detection and 99.1% for benign tumors, with precision rates of 99.6% for malignant tumors and 97.5% for benign tumors. These results demonstrate the feasibility of the proposed model as a reliable tool for early breast cancer detection. The findings highlight the potential of deep learning in medical image processing, suggesting that this technology could be further developed into an accessible, efficient early detection system for breast cancer in clinical settings. Future research could explore the integration of additional imaging modalities and the application of this model in real-world healthcare environments

Abstract

This research was conducted to investigate evidence of an attack and to restore data after an attacker compromised an Open Journal System (OJS) service on a computer server. The method used in this research is a new approach developed from the Network Forensic Digital Life Cycle (NFDLC) method. This new method, known as KUAD, has several stages for collecting cyber-attack evidence and restoring it after the Gacor attack has occurred. The stages in the KUAD method include initiation, acquisition, execution, mitigation, and disposition. The novelty of this method, compared to the previous one, lies in the inclusion of the mitigation stage, which aims to restore data or documents after an attack. The tool used to detect the attack and find evidence of the attack is Tripwire, whereas the tools used to restore lost data include crontab, which runs backup commands with rsync in four steps. Tripwire can optimally detect attacks by displaying the number of data entries that were added, deleted, or modified. A total of 15,135 files in .docx, .pdf, and .jpg formats, deleted by the attacker, were successfully restored using this backup technique. The success rate of using this technique for post-cyber attack mitigation reached 100%.

Abstract

Spanning Tree Protocol (STP) is used in manageable switch devices that apply more than one path to the connection between switches. This study aims to assist engineer staff in improving STP network security. Furthermore, the benefit is to improve the STP network security system by using the Spanning Tree Protocol and Virtual Local Area Network (VLAN) trunking mitigation techniques. The results of testing data before STP is attacked, after STP attacked, and anticipatory data. Then a simple linear regression analysis is carried out by the result of that there is not a significant relationship between time and size in the DoS attack, which  48.6% of the time variable is influenced by the size of  variable, while  the remaining 51.4% by other variables. Root attack is 43.8%-time variable is influenced by size variable, the remaining 56.2% by other variables. Correlation between Karl Pearson DoS and root, there is a significant relationship between time and size, with the DoS correlation coefficient (-0.697) in contrast root (-0.662), and paired sample t-test (paired sample t-test) can be concluded the anticipation which is done by using BPDU guard and root guard mitigation.

Abstract

Routing dinamis tidak hanya digunakan untuk mengelola jaringan komputer dengan jumlah router yang banyak atau lebih dari 10 router, tetapi dapat juga digunakan untuk mengelola jaringan komputer dengan jumlah router yang lebih sedikit dari itu. Salah satu routing dinamis yang banyak digunakan adalah OSPF. Dengan jumlah router yang sedikit seperti dalam penelitian ini hanya 2 buah, maka OSPF dengan single area menjadi pilihan untuk membandingkan dua buah router dari pabrikan yang berbeda dalam melayani audio streaming. Data suara dari komputer yang menjalankan audio streaming diubah menjadi tingkat kebisingan menggunaan perangkat lunak sound meter yang berbasis android menghasilkan nilai tertinggi 83 dan terendah 79 pada jaringan yang menggunakan router berbeda tersebut. Hasil analisa menggunakan analisa deskriptif menunjukan selisih yang tidak terlalu besar yang menyatakan bahwa router cisco seri 2600 memberikan layanan untuk audio streaming yang lebih baik dibandingkan mikrotik seri RB951Ui.
