Abstract

Public Wi-Fi networks are highly vulnerable to the misuse of Internet access, particularly for accessing websites containing online gambling, pornographic content, and illegal online lending services. Similar issues were identified in the public Wi-Fi network of Bukit Peninjauan II Village, which lacked an effective website filtering mechanism. This study aims to implement a network security system using MikroTik firewall integrated with DNS Static based on Regular Expressions (Regex), TLS Host Filtering, and the blocking of DNS over HTTPS (DoH) and QUIC protocols. This study used the Network Development Life Cycle (NDLC) methodology, which consists of the analysis, design, implementation, testing, and evaluation phases. The proposed system was implemented on the public Wi-Fi network of Bukit Peninjauan II Village by configuring firewall rules to filter website access based on predefined domain patterns. The results demonstrate that the implemented Firewall Filter, DNS Static Regex, TLS Host Filtering, DNS over HTTPS (DoH) blocking, and QUIC blocking functioned as intended. The system successfully restricted access to websites related to online gambling, pornographic content, and illegal online lending services without affecting access to authorized websites. Furthermore, blocking DoH and QUIC effectively prevented users from bypassing the implemented filtering mechanism. In conclusion, the proposed network security system effectively enhances Internet access control and provides a safer, more secure, and better-managed public Wi-Fi environment for the community of Bukit Peninjauan II Village.

Abstract

Abstract: Mozza Computer is a computer shop that sells computers, printers, computer spare parts, computer accessories and provides computer and printer services. So far, the service process has been carried out by consumers coming directly to Mozza Computer with computers or printers that are having problems, then the service division will first check whether the device can be worked on directly or not. This requires quite a long time because consumers who come must queue because of limited employees to check for damage to the computer. An expert system for diagnosing computer hardware damage using the Case Based Reasoning Method on Mozza Computer was made to serve as a tool in making it easier to find out damage to computer hardware through an expert system application. In the process of identifying hardware damage, an analysis of the latest data will be carried out with case data that has occurred for a long time to obtain a percentage level of confidence in the damage. Based on the results of the tests that have been carried out, the functionality of the expert system for diagnosing computer hardware damage using the Case Based Reasoning Method on Mozza Computer has gone well as expected and is able to provide information on the results of consulting computer hardware damage
