Abstract

Computer communication is done by first synchronizing one computer with another computer. This synchronization contains Data Packages which can be detrimental if done continuously, it will be categorized as an attack. This type of attack, when performed against a target by many computers, is called a distributed denial of service (DDoS) attack. Technology and the Internet are growing rapidly, so many DDoS attack applications result in these attacks still being a serious threat. This research aims to apply the Threshold method in detecting DDoS attacks. The Threshold method is used to process numeric attributes so obtained from the logfile in a computer network so that data packages can be classified into 2, namely normal access and attack access. Classification results using the Threshold method after going through the fitting process, namely detecting 8 IP Addresses as computer network users and 6 IP addresses as perpetrators of DDoS attacks with optimal accuracy.

Abstract

Resource digital memerlukan sebuah mekanisme untuk mengatur policy terhadap kontrol untuk mendapatkan hak akes ke dalam suatu sistem. Akses kontrol lebih fleksibel dibanding dengan pendekatan otorisasi, autentikasi ataupun verifikasi yang sangat sederhana. Mekanisme access control policy dengan pendekatan atribut diyakini sebagai solusi adaptif yaitu ABAC (Attribute Based Access Control) dengan implementasi model XACML (Extensible Access Control Modelling Language). Desain policy ABAC ini disajikan dengan atribut-atribut dari salah satu studi kasus resource digital dengan sistem e-Library. e-Library merupakan salah satu resource digital dimana proses autentikasinya belum dimodelkan dengan atrubut subjek yang ada. Penelitian ini diawali dari identifikasi atribut dari rule, pemodelan ABAC resource digital, implementasi XACML, simulasi sistem dan analisis sistem. Hasil dari pengujian akses kontrol menggunakan ALFA (Axiomatics Language for Authorization) untuk pemberian kinerja akses kontrol terhadap resource digital. Hasil analisis dengan pendekatan ABAC dengan model XACML ini menyajikan suatu keamanan sistem dengan model akses kontrol berbasis atribut dari policy statement untuk menjadi solusi model akses kontrol yang dibuat sebelumnya dan mendukung model akses kontrol yang relevan untuk resource digitalAbstractDigital resources require a mechanism to regulate policy against controls to get access rights to a system. Access control is more flexible than the very simple approach of authorization, authentication or verification. The access control policy with the attribute approach is believed to be an adaptive solution, namely ABAC (Attribute Based Access Control) with the implementation of the XACML (Extensible Access Control Modeling Language) model. This ABAC policy design is presented with attributes from one of the digital resource case studies with the e-Library system. e-Library is one of the digital resources where the authentication process has not been modeled with the existing subject matter. This study begins with the identification of the attributes of the rule, digital ABAC resource modeling, XACML implementation, system simulation and system analysis. The results of testing access control using ALFA (Axiomatics Language for Authorization) to provide performance control access to digital resources. The results of the analysis using the ABAC approach with the XACML model present a system security with attribute-based access control models from policy statements to be a solution to the previously created access control model and support the access control model relevant for digital resources

Abstract

Ucapan merupakan sinyal yang memiliki kompleksitas tinggi terdiri dari berbagai informasi. Informasi yang dapat ditangkap dari ucapan dapat berupa pesan terhadap lawan bicara, pembicara, bahasa, bahkan emosi pembicara itu sendiri tanpa disadari oleh si pembicara. Speech Processing adalah cabang dari pemrosesan sinyal digital yang bertujuan untuk terwujudnya interaksi yang natural antar manusia dan mesin. Karakteristik emosional adalah fitur yang terdapat dalam ucapan yang membawa ciri-ciri dari emosi pembicara. Linear Predictive Coding (LPC) adalah sebuah metode untuk mengekstraksi ciri dalam pemrosesan sinyal. Penelitian ini, menggunakan LPC sebagai ekstraksi ciri dan Metode Euclidean Distance untuk identifikasi emosi berdasarkan ciri yang didapatkan dari LPC.  Penelitian ini menggunakan data emosi marah, sedih, bahagia, netral dan bosan. Data yang digunakan diambil dari Berlin Emo DB, dengan menggunakan tiga kalimat berbeda dan aktor yang berbeda juga. Penelitian ini menghasilkan akurasi pada emosi sedih 58,33%, emosi netral 50%, emosi marah 41,67%, emosi bahagia 8,33% dan untuk emosi bosan tidak dapat dikenali. Penggunaan Metode LPC sebagai ekstraksi ciri memberikan hasil yang kurang baik pada penelitian ini karena akurasi rata-rata hanya sebesar 31,67% untuk identifikasi semua emosi. Data suara yang digunakan dengan kalimat, aktor, umur dan aksen yang berbeda dapat mempengaruhi dalam pengenalan emosi, maka dari itu ekstraksi ciri dalam pengenalan pola ucapan emosi manusia sangat penting. Hasil akurasi pada penelitian ini masih sangat kecil dan dapat ditingkatkan dengan menggunakan ekstraksi ciri yang lain seperti prosidis, spektral, dan kualitas suara, penggunaan parameter max, min, mean, median, kurtosis dan skewenes. Selain itu penggunaan metode klasifikasi juga dapat mempengaruhi hasil pengenalan emosi. AbstractSpeech is a signal that has a high complexity consisting of various information. Information that can be captured from speech can be in the form of messages to interlocutor, the speaker, the language, even the speaker's emotions themselves without the speaker realizing it. Speech Processing is a branch of digital signal processing aimed at the realization of natural interactions between humans and machines. Emotional characteristics are features contained in the speech that carry the characteristics of the speaker's emotions. Linear Predictive Coding (LPC) is a method for extracting features in signal processing. This research uses LPC as a feature extraction and Euclidean Distance Method to identify emotions based on features obtained from LPC. This study uses data on emotions of anger, sadness, happiness, neutrality, and boredom. The data used was taken from Berlin Emo DB, using three different sentences and different actors. This research resulted in inaccuracy in sad emotions 58.33%, neutral emotions 50%, angry emotions 41.67%, happy emotions 8.33% and bored emotions could not be recognized. The use of the LPC method as feature extraction gave unfavorable results in this study because the average accuracy was only 31.67% for the identification of all emotions. Voice data used with different sentences, actors, ages, and accents can influence the recognition of emotions, therefore the extraction of features in the recognition of speech patterns of human emotions is very important. Accuracy results in this study are still very small and can be improved by using other feature extractions such as provides, spectral, and sound quality, using parameters max, min, mean, median, kurtosis, and skewness. Besides the use of classification methods can also affect the results of emotional recognition.
