Abstract

Recorded two hospitals in Jakarta were hit by cyberattacks which caused patient data in hospital computer networks to be inaccessible. Symantec is an American company that manufactures data security software, according to Symantec's report entitled Internet Security Threat Report Volume 24 which was released in February 2019 then, in 2018, as much as 2.23%, cyberattacks in the global arena occur in Indonesia, increasing from the previous year, namely 1.67%. Meanwhile, the figure also places Indonesia in fifth place as the country that has the most cyber threats in 2018. It can operate on physical networks or on virtual networks. The only requirement is that the Ridgeback installation has access to the layer 2 network layer. Ridgeback Network Defence makes resistance to intruders using interactive defences and causes intruders to spend unnecessary resources. Interactive Defence is an advanced disguise and fraud capability designed to ensnare intruders in several ways, namely by managing billions of feeds in the network that can trigger intruder responses, affect intruder behavior so that they are easier to detect, and block access to protected network services without revealing that service has been blocked. This research is expected to create a control center by adopting a Software Defined Network (SDN) so that it can capture intruders and get data about the attack, which can be used as evidence in the process of investigating network forensics quickly and precisely.

Abstract

An entrepreneur or a service provider in the internet network world, will certainly find clients with different characters. Clients who are not technology blind, especially routers, sometimes want full access to the router, or some clients who ask to add a router to be able to directly access the router in full. Virtual Router allows clients to process their own network, as if the client has a router. Network forensics has the ability to reconstruct events using a system that stores all data traffic activities on the network, so that investigations can be carried out by looking back at events that have occurred and analyzing events that occurred in the past. Wireshark can review data packages in real time. This means that the wireshark application will monitor all incoming and outgoing data packets through a predefined interface and the next will display the results of the data package

Abstract

In an increasingly advanced digital era, computer networks play an important role in supporting various activities, including in the community-initiated RT/RW Net environment. This research aims to analyze Quality of Service (QoS) on the RT/RW Net network to improve service efficiency and productivity. The research method used is the experimental method, which involves data collection through the Mikhmon application to monitor network performance. QoS measurements were made based on four main parameters: throughput, delay, jitter, and packet loss.The results show that the RT/RW Net network has excellent throughput with a value of 1471 Kb/s, average delay of 3.623 ms, jitter of 3.63 ms, and packet loss of 0%, all of which fall into the "Very Good" category according to Tiphon standards. Security testing was also conducted by simulating a brute force attack, which revealed several weaknesses in the security system that require improvement.The conclusion of this study is that the RT/RW Net network has a very good quality of service, but needs improvement in the security aspect. Suggestions include increasing bandwidth capacity, implementing stricter security policies, and improving connection stability.

Abstract

Data security in cloud computing environments has become a major concern as system architectures grow increasingly complex, distributed, and open to external access. One of the essential components in maintaining system security is the Intrusion Detection System (IDS), which is responsible for identifying suspicious activities and cyberattacks. However, traditional IDS implementations face several limitations, including the vulnerability of log integrity, limited scalability in dynamic cloud environments, and reliance on centralized architectures that are prone to single points of failure and internal threats. To address these challenges, the integration of blockchain technology into IDS has emerged as an innovative solution. Blockchain offers decentralization, transparency, and immutability of records, which are highly relevant for strengthening IDS reliability and trust.This study employs a literature review methodology by examining scholarly articles, academic journals, and real-world case studies focusingon blockchain-based IDS implementations within cloud computing infrastructure. The findings suggest that using blockchain—particularly permissioned frameworks such as Hyperledger Fabric—can significantly enhance the integrity of IDS logs, enable transparent and verifiable audit trails, and support secure multi-tenant collaboration in both public and private cloud settings. Furthermore, the combination with machine learning techniques, federated learning, and Zero Trust Architecture (ZTA) increases the detection accuracy and responsiveness of the system. Nevertheless, several challenges remain, including transaction efficiency, computational overhead, and system integration complexity. Therefore, a carefully designed and optimized architecture is required tomaximize the benefits of blockchain-based IDS in cloud environments.

Abstract

The increasing use of wireless networks, such as Indihome WiFi, raises significant concerns regarding network security. Cyber threats like data theft, unauthorized access, and malware attacks can compromise user privacy and data integrity. Therefore, monitoring network traffic is essential to detect and mitigate potential security risks. This study explores the implementation of Wireshark, a widely used network protocol analyzer, to monitor security on Indihome WiFi networks. Wireshark enables real-time packet capture and analysis, allowing for the inspection of data traffic, detection of suspicious activities, and identification of vulnerabilities. This research focuses on analyzing network protocols, identifying anomalies such as unauthorized access attempts, and evaluating encryption effectiveness. The methodology involves capturing WiFi packets, filtering data based on protocols (e.g., TCP, UDP, HTTP), and analyzing potential security threats like ARP spoofing or DNS hijacking. The results indicate that Wireshark effectively detects irregular traffic patterns, unencrypted data transmissions, and potential intrusion attempts. However, its effectiveness depends on proper configuration and user expertise in interpreting packet data. The study concludes that Wireshark is a valuable tool for enhancing Indihome WiFi security but should be complemented with other security measures such as firewalls, strong encryption (e.g., WPA3), and regular network audits. Future research could explore automated threat detection integration with Wireshark to improve real-time response capabilities.
