Abstract

The internet enables people to connect through their devices. While it offers numerous benefits, it also has adverse effects. A prime example is malware, which can damage or even destroy a device or harm its users, highlighting the importance of cyber security. Various methods can be employed to prevent or detect malware, including machine learning techniques. The experiments are based on training and testing data from the UNSW_NB15 dataset. K-nearest neighbor (KNN), decision tree, and Naïve Bayes classifiers determine whether a record in the test data represents a Shellcode attack or a non-Shellcode attack. The KNN, decision tree, and Naïve Bayes classifiers reached accuracy rates of 96.26%, 97.19%, and 57.57%, respectively. This study's findings aim to offer valuable insights into the application of machine learning to detect or classify malware and other forms of cyberattacks.

Abstract

Sinyal yang ditransmisikan dari suatu pemancar radio detection and ranging adalah berupa gelombang elektromagnetik yang diarahkan ke arah objek dan memiliki cakupan wilayah sebaran gelombang untuk mendeteksi objek melalui sinyal pantulan dari objek ke bagian penerima radio detection and ranging. Media wireless yang digunakan untuk transmisi sinyal ke objek dipengaruhi gangguan dari derau sehingga sinyal terima pantulan objek tidak maksimal dalam penerimaan di radio detection and ranging receiver. Pergerakan objek dan perpindahan posisi objek menghasilkan respon atau tanggapan dari radio detection and ranging. Pada penelitian ini, sinyal pergerakan doppler objek dioptimasi melalui pemulihan L1-minimization dan pemulihan sinyal terima dari perangkat radio detection and ranging array berhasil dilakukan. Pengujian perangkat array juga berhasil dilakukan terhadap objek di jarak satu meter, dua meter dan tiga meter dengan masing-masing pergerakan objek ke arah kanan dan ke kiri dari posisi awal objek terhadap perangkat array sejauh 50 cm dan 100 cm. Array pada perangkat transceiver radio detection and ranging diletakkan sejajar menghadap objek. Hasil pengukuran kinerja pemulihan sinyal menggunakan L1-minimization dan estimasi sinyal menghasilkan amplitudo tegangan sinyal hasil paling baik yaitu 359725.8655 V pada jarak 50 cm pergerakan objek ke arah kanan perangkat array sedangkan mean square error yang dihasilkan 1.653 % pada rasio signal to noise 226773.8723 dB serta 290737.6723 dB sebagai hasil dari rasio peak signal to noise.

Abstract

The provision of fiber optic infrastructure in dense urban areas like Taman Kambang Iwak, Palembang, often faces constraints related to excavation permits and potential damage to city aesthetics. 5G-based Fixed Wireless Access (FWA) technology serves as a strategic alternative solution to deliver high-speed broadband access without requiring physical cable installation to the user's premises. This study aims to design a 5G FWA network utilizing the 3500 MHz frequency (Band n78) with a 100 MHz bandwidth. The design was conducted through simulation using RadioPlanner 3.0 software with the Okumura-Hatta propagation model tailored for urban environmental characteristics. Analyzed parameters included signal coverage based on Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ) and data capacity (throughput). Simulation results indicate that the design scenario using three sectoral antennas is capable of providing "Good" category signal coverage in the target area. In terms of data performance, the system achieves a maximum downlink throughput of up to 750 Mbps and uplink ranging from 500 Mbps to 750 Mbps. (Discussion) Based on these results, the implementation of 5G FWA at the 3.5 GHz frequency is proven feasible and meets the standards for high-speed data service requirements in the Taman Kambang Iwak area..

Abstract

The Internet can link one person to another using their respective devices. The internet itself has both positive and negative impacts. One example of the internet's negative impact is malware that can disrupt or even kill a device or its users; that is why cyber security is required. Many methods can be used to prevent or detect malware. One of the efforts is to use machine learning techniques. The training and testing dataset for the experiments is derived from the UNSW_NB15 dataset. K-Nearest Neighbour (KNN), Decision Tree, and Naïve Bayes classifiers are implemented to classify whether a record in the testing data is Shellcode or non-Shellcode attack. The KNN, Decision Tree, and Naïve Bayes classifiers achieve accuracy levels of 96.82%, 97.08%, and 63.43%, respectively. The results of this research are expected to provide insight into the use of machine learning in detecting or classifying malware or other types of cyber attacks.

Abstract

Internet dapat menghubungkan satu orang dengan orang lain dengan menggunakan perangkat masing-masing. Internet sendiri memiliki dampak positif dan negatif. Salah satu contoh dampak negatif dari internet adalah adanya malware yang dapat mengganggu atau bahkan merusak perangkat atau penggunanya; itulah mengapa keamanan siber diperlukan. Banyak cara yang dapat dilakukan untuk mencegah atau mendeteksi malware. Salah satunya adalah dengan menggunakan teknik machine learning. Dataset pelatihan dan pengujian untuk eksperimen ini berasal dari dataset UNSW_NB15. K-Nearest Neighbour (KNN), Decision Tree, dan Naïve Bayes diimplementasikan untuk mengklasifikasikan apakah sebuah record pada data testing merupakan serangan Shellcode atau non-Shellcode. Classifier KNN, Decision Tree, dan Naïve Bayes mencapai tingkat akurasi masing-masing sebesar 96.82%, 97.08%, dan 63.43%. Hasil dari penelitian ini diharapkan dapat memberikan wawasan mengenai penggunaan machine learning dalam mendeteksi atau mengklasifikasikan malwares atau jenis serangan siber lainnya
