Abstract

In the digital age, networks are an important factor for implementing communication and exchanging information. Campus networks, which are private networks specifically designed for a particular institution, are essential for the institution because they provide access to the necessary information and services. However, campus networks are also vulnerable to security threats such as cybercrime and malware attacks. Firewall implementation can minimize these threats by controlling access to network services. Pundi Mas Berjaya (PMB), a company that provides software solutions to the global market, requires a highly available and redundant campus network. This research uses Cisco Packet Tracer to design and configure the network required by PMB. Implementing a highly available and redundant campus network with a hierarchical network model will improve the performance of the PMB campus network connectivity and security.

Abstract

Currently, many agencies or companies use computers to work in the office. MicroServer is a tiny piece of hardware to help smooth system operations. MicroServer has an essential function in computers, to limit local networks and internet networks. Proliant HPE is an alternative MicroServer to use servers easily and quickly. In this analysis design, the author uses a descriptive qualitative analysis research method in which the author sees and tests the speed of data transfer on a ProLiant HPE microserver. As for the analysis results, the author has the ambition to create a backup plan if he feels the network and cloud server is unsafe to focus on physical products such as servers or microservers. The resulting speed is considered feasible enough if using a local/internal network using a LAN, as for testing with servers and microservers,

Abstract

Wireless Network is a collection of electronic devices that connect to each other using air devices or frequencies as a data traffic flow. Today, there are many users who use WPA2-PSK or WPA2-EAP as a wireless network security system that aims to prevent people from accessing it without permission. This research uses a wireless penetration testing technique that uses fluxion tools by comparing and analyzing the WPA2 authentication security system with EAP-PSK on a wireless network which aims to determine the vulnerability of a network security system. To carry out penetration testing, the author refers to the "Wireless Network Penetration Testing Methodology." Which consists of intelligence gathering, vulnerability analysis, threat modeling, password cracking, and reporting. From this study, it will be concluded that WPA2-PSK is less safe to use because it can be seen in the penetration testing that WPA2-PSK was successfully hacked in an unhide SSID state, while WPA2-EAP was successful in making Web Interfaces but failed to obtain information such as usernames and passwords. If the WPA2-PSK SSID is in a hide state, it will fail the hack, so that both security systems have their own advantages and disadvantages depending on the user's needs

Abstract

Internet Service Providers (ISPs) provide internet services, both for local and international internet connections. The need for internet bandwidth is increasing day by day, sometimes 1 ISP is not enough to support our needs. In some large companies that rely heavily on internet access, of course they have several internet providers for network backups when one ISP goes down. One way of implementing backup and merging of Internet ISP lanes requires load balancing techniques. The method used is Equal Cost Multi Path which is a load balancing technique that uses a per addresspair connection load balancing method. ECMP allows routers to have more than one gateway for a single destination network. This method can be useful to overcome if one ISP is disconnected it will be able to be replaced by a second ISP so that the internet is not immediately lost. The results obtained after implementing ECMP load balancing, companies and users will continue to be connected to the internet, and work will not be interrupted when the main ISP is down

Abstract

Umumnya sebuah organisasi maupun individu yang membangun perangkat menggunakan konsep pembuatan dengan arsitektur monolitis dan untuk menghemat resources biasanya diaplikasikan pada virtualisasi berbasis hypervisor. Tetapi arsitektur monolitis memiliki permasalahan pada fleksibilitas dan skalabilitas. Pada penelitian yang dilakukan oleh Jaramillo, Nguyen, & Smart menghasilkan data yang menunjukkan bahwa penggunaan Docker dengan bantuan alat-alat lainnya dapat meningkatkan efisiensi serta otomatisasi pada arsitektur aplikasi microservices. Oleh karena itu, penulis merancang sebuah penilitian yang mengaplikasikan konsep microservices sebagai pengganti arsitektur monolitis pada container menggunakan Docker. Kemudian penulis akan melakukan pengujian performa berbasis Load Testing menggunakan aplikasi Apache JMeter. Hasil implementasi menunjukkan kemudahan dalam penggunaan dan aplikasi microservice pada Docker dan stabilitas yang baik saat pengujian berbagai load menggunakan Apache Jmeter.

Abstract

During this COVID-19 pandemic, most office employees are required to implement health protocols such as washing hands, wearing masks, and social distancing. The application of health protocols in the world of work can be in the form of Work From Home. Work From Home is one way to implement social distancing to reduce the spread of the coronavirus or COVID-19. In this case, employees find it difficult to access office data. For this reason, secure technology such as VPN is needed to connect the office network to the home network so that every employee can access the data in the office. With the hope that these employees can work productively even though they are not in the office. That technology is ZeroTier. ZeroTier is a technology that allows connecting personal devices and other devices without having to be in a close location. Devices also don't have to be connected to the same network to use ZeroTier. The method used in this research is the Network Development Life Cycle. With the results of the research that ZeroTier's extensive scalability and operating system support are quite varied, it is possible for every end-user who has an internet network to connect to the same ZeroTier server network. That way each end-user can communicate directly like being on a local network such as pinging, file sharing, or printer sharing.

Abstract

Sebuah infrastruktur jaringan yang baik sangat dibutuhkan bagi perusahaan. Infrastruktur dikatakan baik bila dapat mengatasi ratusan maupun ribuan request dari client dan tidak mengalami down. Pada penelitian Mohamad Rexa, performa web server dalam Docker Swarm meningkatkan availability layanan sebesar 31% percontainer yang ada. Dan juga pada penelitian Imron, Kubernetes Cluster mampu menangani jumlah permintaan client 19 kali lipat dibanding single server. Oleh karena itu penulis merancang infrastruktur dari Docker Swarm dan Kubernetes. Kemudian melakukan performance testing kepada dua infrastruktur tersebut dengan tujuan untuk mengetahui perbandingan dari performa dua kontainerisasi tersebut. Dari hasil perbandingan, perusahaan maupun instansi dapat memilih infrastruktur jaringan yang cocok sesuai kebutuhan
