"NIDPS (Network-based Intrusion Detection Prevention System) merupakan sistem keamanan jaringan komputer yang mampu melindungi seluruh host yang ada dalam jaringan dengan cara mendeteksi dan melakukan pencegahan serangan sebelum sampai di host. Pada skripsi ini dilakukan implementasi NIDPS menggunakan Suricata. Suricata merupakan software IDS yang digunakan untuk melindungi host dengan cara mendeteksi serangan, sedangkan untuk menambahakan fitur pencegahan harus dilakukan konfigurasi pada fitur prevention Suricata dan firewall iptables. Pada skripsi ini akan dilakukan analisis terhadap NIDPS Suricata, meliputi fuctional tes, response time, pengaruh Suricata terhadap performansi jaringan berdasarkan parameter throughput, membandingkan 3 sistem keamanan jaringan yaitu Suricata, Honeyid, dan Ossec dan mencari detection rate dari Suricata. Hasil dari pengujian diperoleh bahwa untuk functional test, Suricata berhasil mendeteksi dan melakukan pencegahan terhadap serangan serta menampilkan serangan yang terjadi pada web-based interface Snorby. Hal ini dapat dilihat dari pengujian SYN flooding attack, Suricata berhasil mendeteski dan mendrop semua paket serangan SYN flooding. Pada pengujian response time, diperoleh response time Suricata untuk 1 serangan 0.015201 detik dan untuk 2 serangan sebesar 0.0435559 detik. Pada pengujian throughput diperoleh bahwa pemasangan Suricata tidak terlalu berpengaruh terhadap performansi jaringan. Perbandingan 3 sistem keamanan yaitu Suricata, Honeyid, dan Ossec, dimana Suricata memiliki rata-rata response time paling cepat dan Honeyd memiliki kemampuan deteksi paling baik dari beberapa pengujian serangan. Sedangkan Suricata kemampuan deteksinya (detection rate) yaitu 0.84 atau 84 % pada 12 pengujian serangan yang berbeda.

NIDPS (Network-based Intrusion Detection Prevention System) is a computer network security system that can protect all hosts on the network by detecting and preventing before the attack up to the host. This final project will be implemented NIDPS using Suricata. Suricata IDS is a software that is used to protect the host by detecting attacks, while adding features for prevention should be configured the prevention features Suricata and firewall iptables. In this final project will be conducted an analysis of Suricata, covering fuctional tests, response time, Suricata influence on network performance use throughput parameter, compare three network security system that is Suricata, Honeyid, and OSSEC and seek detection rate of Suricata. The results obtained from testing that for functional test, Suricata successfully detect and prevent attacks and show that the attack occurred on a web-based interface Snorby. It can be seen from the test SYN flooding attack, Suricata can detect and drop all SYN flooding attack packets. In the response time testing, the response time of Suricata is 0.015201 seconds for 1 attack and 0.0435559 seconds for 2 attack. In the throughput test, Suricata implemented does not affect significantly the network performance. Three comparative of the security system that is Suricata, Honeyid, and OSSEC, where Suricata has an average response time of the fastest and Honeyd has the best detection capability of several attempted attacks. While Suricata detection capability (detection rate) is 0.84 or 84% on testing 12 different attacks."

"ABSTRAKManajemen jaringan menjadi isu yang sangat penting pada lingkungan yang heterogen dan terdiri dari bermacam-macam vendor jaringan komputer. Client/server dengan jumlah komputer yang sangat banyak membutuhkan manajemen jaringan untuk mengelola dan mengontrol jaringan dan komponen jaringan komputer.Tesis ini merupakan studi kasus jaringan pada sebuah perusahaan energi. Perusahaan mempunyai sebuah kantor pusat dan beberapa kantor pendukung di Jakarta dan beberapa kantor di lapangan. Semua perkantoran mempunyai jaringan komputer lokal dan semuanya tersambung melalui Wide Area Network (WAN). Pertumbuhan jaringan dan penggunaan jaringan menimbulkan masalah yaitu dengan menurunnya kinerja jaringan terutama WAN. Studi dimulai dengan melihat permasalahan yang ada dan melakukan studi literatur yang berhubungan dengan masalah. Tahap selanjutnya adalah menjalankan platform manajemen jaringan yang telah dipunyai oleh perusahaan yaitu Openview. Data diambil dengan tujuan mendukung analisis dan selanjutnya untuk memberikan alernatif solusi. Parameter yang dipakai adalah parameter kinerja jaringan yaitu utilisasi dan traffic. Data diambil pada router utama yang menghubungkan antara kantor utama Jakarta dan site lain di lapangan dan Headquarter di USA. Masing-masing link yang terletak pada port serial diamati secara real time dan ditampilkan dalam grafik dengan selang waktu tertentu pada jam kerja maupun jam istirahat kemudian diperbandingkan. Beberapa referensi membuat kriteria untuk menentukan kinerja jaringan berdasarkan utilisasi sehingga berdasarkan pengamatan tersebut dapat diambil kesimpulan.

ABSTRACT

Network Management has become a critical issue particularly in heterogeneous environment and multivendor computer networks. Client-servers with a large number of computers need network management to manage and control the networks and components of networks.

It is a case study at an energy company that has a large computer network with its complexity since the company employee various platform that running multiprotocols. Company has main office and support offices in Jakarta and fields. Each office (site) has Local Area Network (LAN) and all of them were connected through Wide Area Network. Network growth rapidly and consequently the network performance decreases especially for Wide Area Network. First stage of study is investigation problem and learn from the literature related to problem. Second stage was try and run Network Management Platform Openview and setup the parameter and display. Data was acquired to support the analysis and eventually giving the solution. The parameter that was chosen for data acquisiton were utilization and traffic which are belong to performance management. Data was acquired at main router that makes connections between Jakarta - Fields, Jakarta - Headquarter and Jakarta to other Jakarta sites. The links that were located at serial ports of router were captured in real time mode in the work time and rest time and then were displayed in graphics. Some references made a criterion for network performance evaluation based on utilization."

"Sistem transportasi pada kota besar seperti Jakarta berkembang seiring dengan bertambahnya jumlah penduduk. Salah satu transportasi di Jakarta yang dianggap dapat mengatasi masalah kemacetan adalah Transjakarta. Untuk dapat melayani calon penumpangnya terutama pada waktu sibuk maka perlu dilakukan penelitian untuk mengetahui karakteristik penumpang. Hal ini dapat dilakukan dengan membuat model simulasi yang dijalankan pada berbagai skenario. Hasil simulasi pada skenario yang dibuat menggambarkan bahwa dengan peningkatan pelayanan yang relatif kecil dapat berdampak besar terhadap kualitas pelayanan.

Transportation system in a big city such as Jakarta grows corresponding to the growth of its population. Transjakarta is one of the transportation systems in Jakarta that expected to lessen the level of congestion. In order to be able to serve the passengers during peak time, the project needs to have a research to find out the passenger characteristics. It can be conducted by making model simulation that runs on different scenarios. The simulation results illustrate that with a relatively small increase in services could have a major impact on quality of service."
