Support Vector Machine (SVM) is a machine learning algorithm that falls into the category of supervised learning. SVM works by constructing an optimal hyperplane that separates two classes in a feature space. This hyperplane is chosen in such a way that it has a maximum margin, which is the largest distance between data points from both classes. In addition to the hyperplane, hyperparameters ar…
Blockchain is a distributed database in which information sent by users is periodically verified and grouped into blocks, thus forming a chain. CITA (Cryptape Inter-enterprise Trust Automation) is a high-performance blockchain system for enterprises with 6 microservices (RPC, Auth, Consensus, Chain, Executor, Network) that exchange information via Message Bus. The process of data retrieval, dat…
Penelitian ini bertujuan untuk mengembangkan model klasifikasi yang akurat untuk mengidentifikasi dan mengkategorikan lalu lintas anonim pada jaringan Tor. Dataset yang digunakan adalah CIC-Darknet2020. Teknik Synthetic Minority Over-sampling Technique (SMOTE) diterapkan untuk menangani ketidakseimbangan kelas, sementara Mutual Information Classifier (MIC) digunakan untuk seleksi fitur. Model K…
This research focuses on the implementation of a tarpit firewall on Router as protection against port scanning attacks. Port scanning attacks, used by attackers to identify active services on a network, are becoming increasingly sophisticated and difficult to detect. Conventional approaches, such as stateful firewalls and intrusion detection systems, have limitations in quickly and effectively …
Building a secure socket tunneling protocol method to access port services on the MikroTikrouterboard. Limiting ports that are easy to access remotely on the MikroTikrouterboard. Knowing the steps of the secure socket tunneling protocol Virtual Private Network (VPN) method is one way to protect the exchange of important information data over the internet network, especially by using the Secure …
Distributed Denial-of-Service (DDoS) attacks pose a serious threat to computer network infrastructures. Apache Spark, as a popular distributed data processing platform, requires effective methods to classify DDoS attacks on Apache Spark in order to enhance system security. In this research, we propose a classification approach using the Long-Short Term Memory (LSTM) method, data preprocessing w…

Penelitian ini menggunakan Arduino sebagai mikrokontroler penggerak solenoid, dan Esp32-cam untuk menscan QR Code. untuk Pemrograman ardui…
Penulis mendapati bahwa permasalahan riil yang terkait security jaringan komputer, khususnya yang terkait dengan aktifitas hacking, sudah mencapai batas ambang "gawat darurat". Sehingga diperlukan obat penawar dengan dosis tinggi untuk mengatasi "penyakit akut"tersebut. Buku ini membahas berbagai tips dan trik untuk menjadi seorang ethical hacker (white hat) ala CEH, dengan gaya bahasa yang m…
Di dalam perkembangan bisnis, web service sungguh sangat dibutuhkan dalam integrasi sistem karena tidak melihat platform, arsitektur maupun bahasa pemrograman yang digunakan oleh sumber berbeda. Keamanan web service ada didalam sepuluh kerentanan teratas dalam keamanan pplication Programming Interface (API) Web Service yang kurang terlindungi menurut The Open Web Application Security Project (O…
In modern times, growing on the Internet in terms of technology and its use can bring many positive things to human life. Surely it cannot be denied that Internet technology has had a negative impact on people as well. Web service security tapped into the top ten vulnerability in the Application Programming Interface (API) web service less protected by OWASP (The Open Web Application Security P…
DDoS TCP Flood attack is a condition where the attacker exploits the three-way handshaking mechanism of the TCP connection establishment process, where the server will be flooded with requests for SYN packets without being responded by the server. In preventing TCP Flood DDoS attacks, we need a system that will detect the attack pattern and then independently reject packets that indicated as at…
Wannacry ransomware is a specific type of malware that threatens access to victims unless their data has been redeemed or paid for. Usually, ransomware encrypts the content on the victim's hard drive making it inaccessible to the victim. After making the payment or ransom, a decryption key will be given to the victim. In this research, a snort detection system is used and the prevention system …
