Abstract

Along with the development of technology and the improvement of socio-economic life in the community, the community's expectations for improving health services and the expectations of patients for health workers have also increased. An agency or institution needs a system or media that can help their needs in achieving work efficiency and effectiveness to improve the quality of service to the community. In this case, the COMMORDIC of the Ngimbang Regional General Hospital has not yet integrated its information system, so there are often difficulties in managing student admissions for internships. So an application or media is needed to facilitate KOMKORDIK in mapping and integrating information systems at Ngimbang Hospital. One of the data processing applications that can be operated freely or without payment and is easy to use is the Microsoft Excel application. Microsoft Excel is designed with functions to help solve administrative problems starting from the simplest to the more complex parts. In making this information system using the waterfall method because the system created is not too large and the scope of development is not so wide that it will be easier if you use the waterfall model, the approach is carried out systematically and sequentially. Making this Microsoft Excel-based information system can assist in processing student data such as student origin data, activity schedule data, and room data that has been provided. The existence of this information system can also help carry out data processing of PKL / Internship student activities effectively and efficiently

Abstract

Linux is an operating system like Unix that uses a kernel and includes applications and other support-ing modules to be used properly. Linux is free to use and includes open-source code to be used and devel-oped by all parties. The Linux operating system is widely used as a server, for example, for hosting web applications or used in cloud computing infrastructure. No wonder Linux is one of the targets of cyberat-tacks. In this study, a simulation of attacks on the Linux operating system was carried out, and one type of Linux distribution tested as a target was Metasploitable2. Metasploitable2 is a Linux operating system that is intentionally made vulnerable to attack; the aim is to be experimental material. In testing, Metasploitable2 was treated as the target of the attack and Kali Linux as the attacker. The initial stage of the attack simulation, carried out using NMap, Metasploitable2 security vulnerabilities can be identified and exploited for later attacks with exploits. The type of exploit used is a backdoor because a backdoor can function to penetrate systems, programs, or networks without going through the authentication pro-cess. In this case, Metasploitable2 has a security hole in its FTP port. The loophole is tried to be exploited. In this case, the way to overcome the attack is by closing all possible entry points to be an attack loop-hole; in this case, Metasploitable2 is port 6200 and disabling anonymous account permissions to upload files using FTP.
