Abstract

Digital document security has become a crucial aspect in preventing unauthorized access to sensitive information. This study proposes and implements a hybrid security model for PDF documents that integrates AES-128 encryption with a One-Time Token (OTT) mechanism as a dynamic access key operating in a local environment. The research method employed is software engineering using a prototyping approach combined with quantitative experimental testing. The evaluation results indicate that the system consistently achieves an access denial rate exceeding 96.7% across all unauthorized access scenarios, including replay attacks and expired token usage. In terms of performance, the system demonstrates high efficiency, with an average encryption time of 2.61 seconds for a 10 MB file. Although performance limitations were observed for extremely large files (~1 GB), this study concludes that the proposed model is an effective, reliable, and practical solution for enhancing the security of digital document distribution without relying on cloud infrastructure.

Abstract

Securing access to servers that store military personnel data is essential to maintain the confidentiality, integrity, and availability of sensitive information within defense institutions. Servers that manage strategic data are often targeted by unauthorized users, making the implementation of a layered security mechanism necessary. Secure Shell (SSH) is commonly used for remote server access. However, if it is configured using default settings, SSH may become vulnerable to attacks such as brute-force attempts and port scanning. These attacks are frequently used by attackers to identify open ports and attempt unauthorized login access. One technique that can be used to improve server security is Port Knocking, which hides service ports from public scanning by requiring a specific sequence of connection attempts before access is granted. Although this technique can reduce the exposure of open ports, a static knocking pattern may still be discovered by attackers. This research proposes an SSH security system that integrates RSA-based port knocking with One-Time Password (OTP) verification as a two-factor authentication mechanism. The RSA algorithm is used to encrypt the knocking sequence so that the access pattern becomes difficult to predict. Meanwhile, OTP verification ensures that only authorized users can complete the authentication process. The study was conducted using an experimental approach within a server environment. The results show that the proposed system can significantly reduce unauthorized access attempts while maintaining acceptable system performance.

Abstract

The spread of provocative narratives on social media during global tensions poses a psychological threat to national stability. This study aims to classify public sentiment regarding World War 3 issues using the Random Forest algorithm to support cyber defense readiness. Data was collected via YouTube API focusing on relevant news channels, preprocessed using TF-IDF, and classified into positive, negative, and neutral categories. The Random Forest model was configured with 100 estimators and evaluated using 5-fold cross-validation. The results show that Random Forest achieved an accuracy of [Isi % Accuracy] with higher precision compared to other methods. Negative sentiment dominated by fear and uncertainty indicates potential vulnerability to psychological operations. It is concluded that this model can serve as an early warning system for monitoring information warfare threats.

Abstract

As cyber threats grow more complex, automated solutions for malware detection are no longer optional but essential. The integration between Security Information and Event Management (SIEM) such as Wazuh and reverse engineering platform Ghidra offers great potential in enhancing cyber defense capabilities. Wazuh plays a role in real-time log-based threat monitoring, while Ghidra enables in-depth analysis of binary code and malware. This research aims to develop an Automated Threat Intelligence system by integrating Wazuh and Ghidra to perform automated and continuous malware analysis. The methods used include configuring Wazuh to collect security logs from various endpoints, and utilizing APIs and scripts in Ghidra to automate the disassembly and analysis of malicious code. The results show that the system is able to proactively detect threats, accurately analyse malware, and generate comprehensive cyber intelligence. The implication is that this solution can increase the speed of response to cyberattacks, reduce reliance on manual intervention, and strengthen automation-based mitigation strategies. As such, this research makes a significant contribution to the development of adaptive and data-driven cybersecurity systems.

Abstract

The increasing complexity of computer network infrastructures requires a systematic and user-friendly security auditing mechanism. One of the essential stages in network security auditing is port scanning, which is used to identify active services that may pose potential security vulnerabilities. However, most tools such as Nmap are still based on a Command Line Interface (CLI), requiring technical expertise to interpret the scanning results effectively.This study aims to design and implement a Graphical User Interface (GUI)-based port scanning application named Bryan Scan, which integrates the Nmap engine as a supporting tool for network security analysis. The research method employs the System Development Life Cycle (SDLC) Waterfall model, consisting of requirements analysis, system design, implementation, testing, and evaluation stages. The system is developed using Python, integrating Nmap through system calls and processing XML-based output.The results indicate that Bryan Scan is capable of displaying open ports, active services, operating system detection, and automatically generating a rule-based security risk score. The level of conformity between Bryan Scan and Nmap CLI reaches ≥95%, with improved ease of analysis based on usability testing results. Therefore, the application is feasible to be utilized as a structured and informative tool for internal network security auditing.
