Abstract

Currently, cloud computing technology is implemented by many industries in the world. This technology is very promising due to many companies only need to provide relatively smaller capital for their IT infrastructure. Virtualization is the core of cloud computing technology. Virtualization allows one physical machine to runs multiple operating systems. As a result, they do not need a lot of physical infrastructures (servers). However, the existence of virtualization could not guarantee that system failures in the guest operating system can be avoided. In this paper, we discuss the monitoring of hangs in the guest operating system in a virtualized environment without installing a monitoring agent in the guest operating system. There are a number of forensic applications that are useful for analyzing memory, CPU, and I/O, and one of it is called as LibVMI. Drakvuf, black-box binary analysis system, utilizes LibVMI to secure the guest OS. We use the LibVMI library through Drakvuf plugins to monitor processes running on the guest operating system. Therefore, we create a new plugin to Drakvuf to detect Hangs on the guest operating system running on the Xen Hypervisor. The experiment reveals that our application is able to monitor the guest operating system in real-time. However, Extended Page Table (EPT) violations occur during the monitoring process. Consequently, we need to activate the altp2m feature on Xen Hypervisor to by minimizing EPT violations.

Abstract

Network security is now increasingly needed in the era of the industrial revolution 4.0. As technology grows, cybercrimes are becoming more and more common, including attacks on a resource. At this time, honeypots are also widely used by large industries for network security, besides that honeypots are also useful for them in developing intrusion and preventing systems. Honeypots are usually used in a virtual environment, they will stimulate a fake system to capture data packets on the network and be analysed offline later for all threats and attacks. This propose of this paper is to detect and prevent building attacks from computer network attackers using an android application. This application can monitor an attack on the server by installing a honeypot tool into the server as an attack detector, then the honeypot log is used as a Rest API using Django framework with MongoDB database. this application can find out if there is an attack on the server, and can block the attacker's IP address.

Abstract

Indonesia termasuk negara dengan angka kejadian tertinggi ketiga di Asia Tenggara. Salah satu kendala dalam pencegahan stunting adalah masih lambatnya pemantauan tumbuh kembang anak terutama di pedesaan. Proses pencatatan tumbuh kembang balita di Posyandu sangat memakan waktu karena masih manual. Pengetahuan masyarakat tentang cara mencegah stunting pada balita masih minim. Selain itu, masyarakat masih kurang aktif dalam melaporkan kasus stunting, proses pendeteksian kasus stunting hanya berdasarkan pengukuran di Posyandu, masyarakat tidak mengetahui laporan kasus keterlambatan perkembangan. Untuk mengatasi permasalahan diatas maka perlu dibangun sebuah sistem informasi untuk mencatat pertumbuhan anak dan secara otomatis menentukan status gizi anak. Orang tua, moderator Puskesmas atau pihak lain yang berkepentingan dapat mengakses sistem informasi ini. Data yang tersimpan di sistem informasi dapat diekspor ke sistem e-PPGBM Kementerian Kesehatan, sehingga operator tidak perlu lagi memasukkan data ke dalam e-PPGBM secara manual. Untuk memudahkan bidan, mengukur tinggi dan berat badan balita menggunakan perangkat IoT, sehingga bidan tidak perlu menuliskannya secara manual. Entry data hasil pengukuran bidan ke dalam aplikasi dapat dilakukan tanpa sinyal internet, sinkronisasi dapat dilakukan setelah bidan berada di tempat yang terdapat sinyal internet. Selain itu, perlu dilakukan edukasi kepada masyarakat tentang bahaya stunting dan cara pencegahannya.

Abstract

Indonesia termasuk dalam negara ketiga dengan prevalensi tertinggi di Asia Tenggara. Salah satu yang masih menjadi kendala dalam pencegahan stunting adalah lambatnya pemantauan tumbuh kembang anak, terutama di wilayah pedesaan. Proses pencatatan pertumbuhan balita di Posyandu membutuhkan waktu yang lama karena masih bersifat manual. Pengetahuan masyarakat tentang cara pencegahan Stunting pada balita masih minim. Selain itu, masyarakat kurang proaktif dalam melaporkan kasus stunting.Proses pendeteksian kasus Stunting hanya berdasar pengukuran di Posyandu, belum ada kesadaran warga yang ingin melaporkan kasus Stunting. Untuk mengatasi masalah diatas, perlu dibangun sebuah sistem informasi untuk mencatat pertumbuhan balita dan secara otomatis menentukan status gizi balita. Sistem informasi ini dapat diakses oleh orang tua, operator Puskesmas atau pihak lain yang berkepentingan.Data yang tersimpan di sistem infromasi tersebut dapat diekspor ke sistem e-PPGBM Kementerian Kesehatan, sehingga operator tidak lagi harus memasukkan data secara manual ke e-PPGBM. Untuk memudahkan bidan,pengukuran berat dan tinggi badan balita menggunakan perangkat IoT, sehingga bidan tidak perlu menulis manual. Proses entri data dari pengukuran oleh bidan ke aplikasi dapat dilakukan tanpa sinyal internet, proses sinkronisasi nantinya dapat dilakukan ketika bidan sudah berada di tempat yang terjangkau sinyal internet. Selain itu, perlu dilakukan penyuluhan kepada warga tentang bahaya Stunting dan cara pencegahannya.
