Analisis Performa Network Intrusion Detection System (Nids) Menggunakan Metode Signature Based dalam Mendeteksi Serangan Denial Of Service (Dos) Berbasis Udp Flooding

Cloud computing telah menjadi tren teknologi yang digunakan oleh berbagai kalangan terutama para pelaku startup dan Perusahaan besar. Beberapa kelebihan yang ditawarkan cloud computing seperti kemudahan untuk membuat layanan cloud sendiri, hemat biaya infrastruktur dan fleksibel dalam menambah atau mengurangi kapasitas layanan sesuai dengan kebutuhan. Terlepas dari kelebihan-kelebihan tersebut, aspek keamanan cloud computing menjadi salah satu faktor yang harus diperhatikan oleh Perusahaan. Penggunaan antivirus dan firewall belum menjamin sistem cloud sepenuhnya aman. Selain itu keterbatasan administrator dalam memonitor traffic dan serangan di seluruh bagian jaringan cloud menjadi kendala dalam pengelolaan cloud computing. Salah satu solusi untuk meningkatkan keamanan jaringan, memonitor serta mengawasi traffic serangan pada cloud computing adalah Network-based Intrusion Detection System (NIDS). NIDS merupakan salah satu jenis Intrusion Detection System (IDS) yang dapat melakukan pemantauan terhadap serangan serta traffic pada seluruh bagian jaringan. Signature based adalah salah satu metode yang dapat digunakan NIDS dalam mengidentifikasi setiap paket data yang keluar dan masuk ke jaringan. Pada penelitian ini, penulis melakukan uji performa NIDS dengan metode Signature Based dalam mendeteksi serangan DoS berbasis UDP Flooding. Penelitian ini juga melakukan analisis terhadap hasil dan evaluasi performa NIDS untuk mengetahui kinerja diterapkannya NIDS dan keakuratan NIDS dalam mengklasifikasikan serangan. Kata Kunci : IDS, Network Intrusion Detection System, NIDS, Cloud Computing, Signature Based Nowadays, cloud computing has become a new trend technology used in various areas, especially in startup and big companies. Cloud computing offers some advantages such as the easiness to create their own cloud services, cost-effective infrastructure and flexible to increase or decrease the capacity of the service in accordance with the requirements. Apart from these advantages, the security aspects of cloud computing is becoming one of the factors that must be considered by the company. The use of antivirus and firewall doesn't guarantee the cloud system is fully secure. Besides that, the limitation of administrator to monitor traffic and attacks throughout the cloud network become a constraint in cloud computing management. One solution to improve network security, traffic monitoring and overseeing attacks on cloud computing using Network-based Intrusion Detection System (NIDS). NIDS is one type of Intrusion Detection System (IDS) which can monitor the attacks and traffic throughout the network. Signature Based is one method that can be used NIDS to identify each packet of data in or out to the network. In this research, the author conducted performances test NIDS with Signature Based method based on UDP Flooding. This research also perform conducted analysis of the result and performance evaluation of NIDS on cloud computing. The aim to determine the performance of NIDS and the accuracy of NIDS in classifying attacks.

Marine Ecotourism Architecture

Tourism is the largest industry and the leading sector of multidimensional development that attracts attention to be developed by many archipelagic countries and regions. Marine ecotourism architecture is the right choice to be developed in an integrated manner based on its components in the form of attractions, accessibility, accommodation, amenities, and tourism, which is abbreviated as 5A tourism. This research article describes an architectural model prototype for marine ecotourism development based on Google SketchUp and Lumion Island Larea-rea as a marine tourism destination in the East Coast Region of South Sulawesi Province, Indonesia. This type of Research and Development applies the ADDIE (Analysis, Design, Development, Implementation, Evaluation) approach. Observation and interview techniques were used in field research to collect data and information which were analyzed descriptively. The results of the research in the form of a prototype architectural model design for developing Larea-rea Island tourism destinations based on 5A show natural and well-maintained ecological attractions because the white sand beaches have not been polluted with clear seawater and natural coral reefs. The architectural concept of marine ecotourism is a miniature island tourism destination that has an attraction in the form of a miniature mangrove forest to prevent beach abrasion and the local cultural theme amenity is reflected in the architecture of "Rumah Sembilan" where on the roof side adapts the design of the traditional Karampuang house. In other words, this marine ecotourism design applies the architectural theme of a recreational environment based on the micro-ecological concept as a building design, the marine adaptive micro-concept as the background, and the pragmatic micro-concept as a regional spatial layout
