Abstract

Voice over Internet Protocol (VoIP) is a communication technology that enables voice transmission over IP-based networks, offering advantages such as cost efficiency, flexibility, and service integration. Despite its benefits, VoIP faces significant security vulnerabilities due to its open architecture and dependence on public internet infrastructure. This study presents a literature-based analysis of the primary security threats targeting VoIP systems, including eavesdropping, Denial of Service (DoS) attacks, spoofing, session hijacking, and Network Address Translation (NAT) traversal problems. The research also discusses a range of countermeasures, including Secure Real-time Transport Protocol (SRTP), Transport Layer Security (TLS), Intrusion Detection and Prevention Systems (IDS/IPS), adaptive firewalls, and robust authentication protocols such as STIR/SHAKEN. While these technical solutions are effective, their success depends on proper implementation and continuous system monitoring. Although there may be minor trade-offs in performance, particularly in latency, such compromises are acceptable under global standards to ensure secure communication. The findings underscore the importance of a layered security strategy that maintains both protection and Quality of Service (QoS), making VoIP a dependable solution for critical sectors such as government, finance, and business.

Abstract

In today's digital era, operating systems play a crucial role in various technological devices. This paper discusses the optimization and modification of Debian, one of the most stable Linux distributions, to enhance its performance as a real-time operating system (RTOS). The primary objectives of this research are to improve the responsiveness, reliability, and stability of Debian in handling real-time tasks. The study involves modifying the kernel, adjusting scheduling settings, optimizing memory management, and integrating specific real-time software. The results of the tests show that the modified Debian provides lower and more stable task execution latency compared to the standard Debian. Tests were conducted using the cyclictest software to measure system latency and Htop to monitor CPU and memory performance. Additionally, the use of the VLC application as a real-world workload demonstrated that the optimized operating system could handle task priorities more efficiently, allocate resources as needed for real-time demands, and maintain stability under heavy workloads. This research significantly contributes to the development of Debian-based RTOS, which can be applied in fields such as industrial automation, robotics, and IoT devices. The optimizations ensure that the operating system can meet the high-performance and real-time reliability demands of these critical applications.

Abstract

The development of quantum computing presents new challenges to the security of data stored and processed by today's computer systems. Quantum computers have the ability to perform calculations at very high speeds, which could threaten the security of currently used encryption algorithms. Therefore, steps are needed to design and implement an operating system that is able to protect data from quantum computing threats. Ubuntu Linux version 22.04, as one of the leading open source Linux distributions, offers high-level security features. To face the era of quantum computing, it is necessary to carry out special development and implementation of this operating system. This research aims to improve the security of the Ubuntu Linux operating system version 22.04 so that it can withstand quantum computing attacks by designing and implementing a quantum-resistant cryptography protocol and testing the security and performance of the resulting system. This research method uses a qualitative approach and research and development (R&D) with literature studies. The research results show that the integration between Liboqs and OpenSSL on Linux Ubuntu 22.04 successfully implements a cryptographic algorithm that is resistant to quantum computing. Although there is a slight performance increase due to the additional overhead of the quantum algorithm, the security of the system in protecting data from quantum computing attacks is proven to be well maintained.

Abstract

The study investigates cryptocurrency investment fraud practices in Indonesia that use social engineering. Fast-growing digital technology presents opportunities and challenges, including an increasing risk of cybercrime. An APJII survey in 2024 showed that there are 221 million people in Indonesia who use the Internet. On the other hand, Kemenkeu predicts the digital economy will grow eightfold by 2030. Cryptocurrency investment scams often use social engineering attacks such as phishing and identity theft. Qualitative descriptive methods are used in this research to conduct literary analysis of various journal articles. The results show that crypto investment fraud has psychological and social consequences in addition to financial losses. To address this problem, the authors suggest increased digital literacy, tighter security policies, and government-industry collaboration to reduce risk and increase public confidence in blockchain and cryptocurrency technologies.

Abstract

The study is to investigate the phenomenon of cybercrime, specifically focusing on the Bjorka data breach at Kominfo. Cybercrime has grown to be a serious threat to Indonesia's cyber security, including data theft, hacking, and malware attacks. This study approach employs qualitative descriptive techniques via a methodical examination of documents, including journal articles from both domestic and foreign publications. Based on analysis, it was found that Bjorka committed data breaches to protest government policies and highlight security weaknesses. The study also explores measures to prevent cybercrime, such as the use of security technology, user training, and the implementation of strict security policies. Encryption tools like Veracrypt should be used to protect sensitive data from theft. The research results are expected to raise awareness and collaborative efforts among governments, associated organizations, and communities to address the threat of cybercrime as well as strengthen national cyber defences
