Abstract

Port Knocking merupakan proses autentikasi yang dilakukan dengan mengetuk port tertentu untuk membuka dan menutup koneksi menuju suatu service. Pada umumnya, Port Knocking memiliki prosedur penetapan daftar port yang bersifat tetap. Hal inilah yang mendorong munculnya penelitian terkait penerapan Secure Random Port List Generator (SRPLG), melalui perancangan sebuah sistem yang mampu mengacak daftar port yang digunakan untuk knocking. Di samping itu, sistem ini juga didesain agar mampu mengirimkan informasi daftar port teracak tersebut kepada client melalui jalur aman. SRPLG server ini akan di integrasikan pada mekanisme autentikasi Port Knocking. Penerapan metode ini bertujuan untuk menciptakan sebuah prosedur autentikasi yang dinamis, aman dan efisien dalam mengamankan Secure Shell server (SSH server). Hasil pengujian yang didapatkan menunjukkan bahwa SRPLG server dalam mengacak daftar Port Knocking mampu menghasilkan daftar port yang selalu berubah setiap kali ada request dari client. Kemudian dari hasil sniffing yang dilakukan terhadap data yang ditransmisikan oleh SRPLG server dan client menunjukkan bahwa seluruh informasi yang ditangkap telah dienkripsi oleh Secure Socket Layer (SSL). Hasil pengujian peforma SRPLG server terhadap jumlah client yang melakukan request, rata-rata membutuhkan waktu antara 0,01 detik sampai 0,06 detik dalam setiap variasi pengujian peformansi. Pengujian terakhir menunjukkan bahwa SSH server telah berhasil diamankan dengan konfigurasi Port Knocking dari serangan port scanning attack, di mana seluruh informasi port yang ditampilkan, tidak ditemukan satupun celah yang dapat eksploitasi.    Port Knocking is an authentication process done by tapping a particular port to open and close the connection to a service. In general, the knocking port has a fixed procedure to assign ports list. This is what prompted the emergence of research related to the implementation of Secure Random Port List Generator (SRPLG), through the design of a system capable of scrambling the list of ports used for knocking. In addition, the system is also designed to be able to transmit random ports list information to clients via a secure path. This SRPLG server will be integrated into the Port Knocking authentication mechanism. Implementation of this method aims to create a dynamic authentication procedure, secure and efficient in securing the SSH server. The test results show that the secure random port list generator server in scrambling the list of knocking ports is able to generate an ever-changing port list every time a client requests. Then from the sniffing done to the data transmitted by the SRPLG server and the client indicates that all captured information has been encrypted by secure socket layer or SSL. Performance test marks SRPLG server to the number of clients who make requests, average takes between 0.01 seconds to 0.06 seconds in every variation of performance testing. In the last test shows SSH server has been successfully secured with Port Knocking configuration from attack port scanning attack, where all port information is displayed, not found any fault that can exploit.

Abstract

News Feature Scoring (NeFS) merupakan metode pembobotan kalimat yang sering digunakan untuk melakukan pembobotan kalimat pada peringkasan dokumen berdasarkan fitur berita. Beberapa fitur berita diantaranya seperti word frequency, sentence position, Term Frequency-Inverse Document Frequency (TF-IDF), dan kemiripan kalimat terhadap judul. Metode NeFS mampu memilih kalimat penting dengan menghitung frekuensi kata dan mengukur similaritas kata antara kalimat dengan judul. Akan tetapi pembobotan dengan metode NeFS tidak cukup, karena metode tersebut mengabaikan kata informatif yang terkandung dalam kalimat. Kata-kata informatif yang terkandung pada kalimat dapat mengindikasikan bahwa kalimat tersebut penting. Penelitian ini bertujuan untuk melakukan pembobotan kalimat pada peringkasan multi-dokumen berita dengan pendekatan fitur berita dan informasi gramatikal (NeFGIS). Informasi gramatikal yang dibawa oleh part of speech tagging (POS Tagging) dapat menunjukkan adanya konten informatif. Pembobotan kalimat dengan pendekatan fitur berita dan informasi gramatikal diharapkan mampu memilih kalimat representatif secara lebih baik dan mampu meningkatkan kualitas hasil ringkasan. Pada penelitian ini terdapat 4 tahapan yang dilakukan antara lain seleksi berita, text preprocessing, sentence scoring, dan penyusunan ringkasan. Untuk mengukur hasil ringkasan menggunakan metode evaluasi Recall-Oriented Understudy for Gisting Evaluation (ROUGE) dengan empat varian fungsi yaitu ROUGE-1, ROUGE-2, ROUGE-L, dan ROUGE-SU4. Hasil ringkasan menggunakan metode yang diusulkan (NeFGIS) dibandingkan dengan hasil ringkasan menggunakan metode pembobotan dengan pendekatan fitur berita dan trending issue (NeFTIS). Metode NeFGIS memberikan hasil yang lebih baik dengan peningkatan nilai untuk fungsi recall pada ROUGE-1, ROUGE-2, ROUGE-L, dan ROUGE-SU4 secara berturut-turut adalah 20,37%, 33,33%, 1,85%, 23,14%.   News Feature Scoring (NeFS) is a sentence weighting method that used to weight the sentences in document summarization based on news features. There are several news features including word frequency, sentence position, Term Frequency-Inverse Document Frequency (TF-IDF), and sentences resemblance to the title. The NeFS method is able to select important sentences by calculating the frequency of words and measuring the similarity of words between sentences and titles. However, NeFS weighting method is not enough, because the method ignores the informative word in the sentence. The informative words contained in the sentence can indicate that the sentence is important. This study aims to weight the sentence in news multi-document summarization with news feature and grammatical information approach (NeFGIS). Grammatical information carried by part of speech tagging (POS Tagging) can indicate the presence of informative content. Sentence weighting with news features and grammatical information approach is expected to be able to determine sentence representatives better and be able to improve the quality of the summary results. In this study, there are 4 stages that are carried out including news selection, text preprocessing, sentence scoring, and compilation of summaries. Recall-Oriented Understanding for Gisting Evaluation (ROUGE) is used to measure the summary results with four variants of function; ROUGE-1, ROUGE-2, ROUGE-L, and ROUGE-SU4. Summary results using the proposed method (NeFGIS) are compared with summary results using sentence weighting methods with news feature and trending issue approach (NeFTIS). The NeFGIS method provides better results with increased value for recall functions in ROUGE-1, ROUGE-2, ROUGE-L, and ROUGE-SU4 respectively 20.37%, 33.33%, 1.85%, 23.14%.
