Abstract

Along with the development of network technology, threats related to the network are also growing, one of which is DDoS (Distributed Denial of Service). The increasingly advanced and affordable network infrastructure makes DDoS happen more and more. From year to year, there is a significant increase in the number of DDoS attack cases. Therefore, it is still necessary to study various algorithms for classifying data in networks that constitute deep DDoS. The SDN network was chosen because it has a simple implementation and does not require a lot of resources because of the information about the network topology and the controller that will be built using Ryu. The method used is the Random Forest algorithm as a method for classifying DDoS attacks. After conducting the research, the researchers found that Random Forest performed well in detecting DDoS attacks. The accuracy is quite high around 90% with an average detection time of 0.3 seconds.

Abstract

Video Video surveillance is a form of surveillance for actions that may violate the law in the form of a collection of frames sent in real-time from a device that has a camera to another device that is tasked with conducting surveillance. However, problems can occur when the frame sent is taken by an unauthorized party, so that it can interfere with the confidentiality of the frame data. In previous research, there is a method for securing these frames, namely in the form of encryption using a block cipher algorithm and not using a stream cipher algorithm. Therefore, in this study, the implementation of the stream cipher algorithm, namely Salsa20, was implemented. Implementation of Salsa20 is applied to systems with client-server network architecture, namely encryption on the server and decryption on the client. After that, tests are carried out related to test vectors, performance, and attacks. The results of the test vector test have been successful because the output from the system is the same as the output on the paper. Furthermore, for the results of the attack test, the sniffing test succeeded in getting the frame on the network but could not get the information because the frame was encrypted and the ciphertext-only attack test failed because it had not succeeded in getting the key or plaintext.

Abstract

Static authentication is very vulnerable to attacks, Therefore, two-factor authentication is carried out by adding OTP as a factor in the authentication. However, even with all the conveniences offered by OTP, OTP is still very vulnerable to attacks, there are many attacks on OTP such as sniffling, wireless interception, etc. Therefore, it is necessary to have a second security for OTP. The SPECK algorithm provides excellent performance in both software and hardware, SPECK Family also has a variety of block and key sizes to match the application requirements and security needs without hindering the performance. OTP is encrypted with the SPECK algorithm to prevent attacks that directed at OTP. The OTP is encrypted with a key and sent to the user which is then sent back by the user to the system to be decrypted using the user's key. The validated OTP is then deleted to avoid duplicate OTPs. The testing of sniffing and KPA attack that was done to OTP was successfully prevented using SPECK algorithm. We can conclude that the result is invisible in sniffing attack testing, and the plaintext generated from KPA didn't match the main plaintext. The validation of the SPECK data is also true because it matches the test vector.

Abstract

Social media is one of the most used media to get information in Indonesia. The high number of social media usage makes the risk of spreading negative content even greater. This was shown in 2018 the Ministry of Communication and Information received 547.506 complaints of negative content on social media where Twitter became the first most complained social media. The number of complaints creates problems if it has to be checked manually. Therefore, the authors propose research to build a negative content detector on Twitter documents. This research uses the Support Vector Machine method and Pipeline for hashtag segmentation. The process starts with preprocessing the data, then do hashtag segmentation with Pipeline, weighting using Term Frequency-Inverse Document Frequency, followed by classification using Support Vector Machine. In this research the test was carried out by K-Fold Cross Validation using 300 data divided into 10 fold. The test results with the highest accuracy were obtained at 0,8325 with learning rate = 0,0001, complexity = 0,001, lambda = 0,1, epsilon = 0,0001 and maximum iteration = 50.

Abstract

Education is the right of all Indonesian without exception. The government is obliged to guarantee the implementation of education at the basic level, therefore the government has launched a program called BOS (‘Bantuan Operasional Sekolah'). In its implementation, schools are required to make an accountability report for the use of BOS funds in accordance with government regulations from the education and culture office regarding technical guidelines for the use of BO funds. In reporting the use of BOS funds, several obstacles were encountered, namely frequent delays in reporting which caused the regional coordinator to recap data to be hampered, so that the purpose of this study was to build an information system that could monitor schools so that reports on the use of BOS funds to be more controlled. System development is carried out using the waterfall model. In this study, the problem can be overcome by changing the current business process into a recommendation business process so as to produce functional requirements that will be implemented on a website-based information system whose design uses an object-oriented approach which will be implemented in the system using the PHP framework, CodeIgniter. After the information system built is valid according to user needs, then testing is carried out using user acceptance testing so that the user acceptance index of the system being built is known. Based on this test, the results show that the user accepted the information system and the features in it.
