Abstract

Industrial technology development needed solutions about increasing computing resource performance. The one of alternative solution could resolve this problem using the high performance computing’s concept example cluster. Cluster could increase performance of computing using many integrated computers in the computer network. cluster had problem in infrastructure system example place and hardware. One of the alternative solutions was virtual computer for infrastructure. one of cloud system services was IAAS. IAAS could produce integrated virtual computation resource on network directly. This study discussed about virtual cluster’s performance using the virtual computer to solve the parallel computing’s problem. Virtual computer in this study used cloud services. The research method was by implementing OpenMPI on a Linux-based computer cluster using five virtual computer and analyzed the performance of the system by different scenario tests. The results of this study Showed that the cloud was able to facilitate user to provide integrated infrastruktures computing service on a network-based and the virtual cluster machine was suitable when large size of data. Ideally, the value of speedup increased when the number of processors increases. The value of Speed-up was ideal when the the data size of 1000 using two nodes (1,346) and three nodes (1.0465). The value of Efficiency decreases when increasing number of processors. Most of the Value of speed-up and efficiency were not ideal at this experiment Because there was the overhead in the parallel system, for example, the additional parallel computing, inter-processor communication and synchronization processes in the cloud as provider of virtual computers.

Abstract

Indonesian Muslim universities utilize WiFi networks as a facility to support the implementation of student and academic lecture activities within the scope of Indonesian Muslim universities. However, with the number of Indonesian Muslim University students around 17,000 people, internet access to the internet network has become slow. In addition, there are several faculties on several floors that do not get wifi signals or get weak signals so students cannot enjoy the internet network. Because it is necessary to measure the signal quality on wireless devices (AP) in each faculty in the scope of UMI with action research methods and analyze the signal quality so that it is known what factors can cause the wifi signal to sometimes be weak or not even get a signal at all

Abstract

The use of academic information systems (siakad) has become mandatory for universities in providing user convenience in online academic administrative activities. However, sometimes college siakad has security holes that irresponsible people can take advantage of by hacking. This study aims to identify security vulnerabilities at XYZ Siakad University. The method used in this study is a vulnerability assessment method. A university syakad will conduct an initial vulnerability assessment by doing footprinting to get information related to XYZ syakad after that a vulnerability scan is carried out using vulnerability assessment tools to identify vulnerabilities and the level of risk found. Based on the vulnerability of the XYZ university's vulnerabilities, it is quite good, with a high risk level of 1, a medium risk level of 6 and a low risk level of 14. Researchers provide recommendations for improvements related to the findings of security holes in XYZ university Siakad from XSS (Cross Site Scripting) attacks, Clickjacking, Brute Force, Cross-site Request Forgery (CSRF) and Sniffing.

Abstract

Website security is an effort to protect websites from hacker attacks connected through a network. Website security needs to be a concern in the midst of many cases of website hacking from irresponsible people, including websites at Indonesian tertiary institutions that provide information and services to the public, students, and alumni of tertiary institutions. Higher education institution websites that can be accessed widely online can create vulnerabilities against threats from hacker attacks. To minimize this vulnerability, it is necessary to test the website of the higher education institution to assess and evaluate the security system of the university's website. The research method used in this study is the Ethical Hacking method which focuses on footprinting techniques and vulnerability scanning by only testing passive attacks. The results of this study have found information related to the target website (the website of an educational institution in one of the cities in Indonesia) and several vulnerability alerts after testing vulnerability scanning with high to low risk levels so that researchers recommend improving vulnerability to minimize security holes exploited by hackers .

Abstract

The web server is one type of server that was most frequently attacked because the web server is the most vital means for storing databases. The most frequently used attack is Denial of Service (DoS). DoS is an attack technique against a system by consuming data resources from a server so that the server cannot be accessed again. Therefore, this study aims to design a network security system by implementing an Intrusion Detection System (IDS) using the Snort application as a detection system in the event of a DoS attack on the web server. by implementing Snort on a web server will help network administrators to ensure that the web server is protected from various threats. The results of this study indicates that the Snort rule that has been created has been successfully detecting attacks that have been tested through the LOIC tools.

Abstract

Twitter is a social media application that can be used on desktop, web and smartphone systems. The large number of Twitter users makes Twitter inseparable from cyber crimes, such as pornography, online gambling, hate speech and other crimes. The purpose of this study is to conduct a forensic investigation on the Twitter Direct Message (DM) application using the NIJ method and determine the success rate of forensic tools in finding deleted data. This study uses the National Institute of Justice (NIJ) method with the stages of identification, collection, examination, analysis, and reporting assisted by forensic tools to obtain digital traces that can be used as evidence. The results obtained from this study were the discovery of evidence of deleted chats and images on Twitter DMs with a success rate of forensic tools (Magnet AXIOM and MOBILEedit) in finding these evidences of 66.66%.
