Abstract

The development and growth of Hospital X is getting bigger and bigger, and has information system in running their operational activities. Hospital X itself has a server to support its activities, especially the administration system which contains data about their patients. With the availability of the network at the Hospital X, either through Wi-Fi or an Ethernet cable, therefore it should be noted the bonds between networks and servers. Furthermore it is an important need nowadays to help minimize and anticipate the hacking crimes of the existing servers. One of the things that can be done is to monitor the administration and conduct vulnerability testing.Based on the background of the problem, it is necessary to evaluate server and network security using the vulnerability / penetration testing. In addition, this study also uses the guidelines of the CEH (Certified Ethical Hacker), Acunetix, and CISSP (Certified Information Systems Security Professional) modules. The testing of this thesis aims to find weaknesses in the administration system at Hospital X. Some problems were discovered after testing, which each of the weaknesses has different handling or treatment, physical security server weak, and unused opened ports that should not be open.The solution offered to solve these problems, are: the use of Acunetix and CISSP as a standard network security as the solution to anticipate weaknesses, to perform maintenance on a regular basis for the hardware, software, and network, to filter the existing port, to increase the level of security of the server, and to test security regularly and periodically, either through consultation with the related field experts or using a guide (like Acunetix, CEH, and CISSP).

Abstract

X University is now growing increasingly large and has a wide variety of information systems to run its operations. One of the most important servers in X University is www.xyz.ac.id. That URL is one of the URLs that are frequented by the public outside to get to know closer about X University in general. Security of web server is usually a matter of an administrator. Sometimes, security issues or server application system and the importance of securing web server neglected only realized after the disaster. Without a good security application systems, the application of technology would be very dangerous as good as any institution or organization itself. Therefore, it takes a server security evaluation and conduct vulnerability mapping to be wary of the security server.Based on the background of the problem, it is necessary to evaluate by using penetration testing. In addition, this study also uses the guidelines of the module CEH (Certified Ethical Hacker) and the official web Acunetix. Testing of this thesis is aimed to find the weaknesses of existing servers. Some problems were found after testing, among others: the weaknesses found pretty much where any weaknesses have different handling, ports should not be open even open, and less important public IP should not be open.The solution provided to overcome these problems include: the use of Acunetix standards can be maintained and continued, testing will be done more than one time, to upgrade web server to a newer version periodically, to filter the existing port, increasing the level of web security server, periodic maintenance, and security testing regularly and periodically, either by consulting the relevant field or using a guide (like Acunetix, CEH, OWASP).

Abstract

The presence of computer laboratory is really helpful in terms of supporting the learning process in the college scope. But the user of the computer itself tend to irresponsibly making change(s) the computer’s configuration. The configuration made by the laboratory’s assistant itself can sometimes be wrong, making the fix to the configuration itself has to be made on each of the computer.The use of Active Directory can be spread easily via server. The limitations of a user group applied based on its own functions. The users itself get their personal space for storing their data in the server, in which if one user uses another computer in the lab, he / she still can access his / her data. Administration also centered on the server thatfacilitate lab’s assistants on helping their task. The re-installation of the computer’s operating system is made easy by using the remote install hosted by server.The result from the usage of Active Directory system is that it will help the administration tasks done by the lab’s assistants, especially on the limitations that should be applied to the groups of users. Personal storage space in the server also helps the students on the availability of their data, regardless where or which computer they are using.

Abstract

PT. X is a company engaged in the pallet industry, such as the production of wooden pallets, plastic pallets distribution, ISPM#15 services, and the services of container checkers. Until now, not all business processes are being supported by information systems because there are many business processes being done manually and the existing information systems are not yet integrated. Existing information systems in the company only supports finance and accounting process. Based on this condition, this thesis will analyze and construct enterprise architecture design for PT. X using Enterprise Architecture Planning method. The first stage will be done with business modeling and analysis of business strategy company. After that, the next step is to see the condition of the company's information technology at the moment, the existing problems within the company, and information technology needs in the future. Then from these, the results will be constructed by making design data architecture, application architecture, and technology architecture. Data architecture generates multiple subsystems at the company, such as sub-system of sales, sub-system of purchase, sub-system of production, sub-system of ISPM # 15, sub-system of container checker, sub-system of IT, sub-system HRD, and sub-system of finance and accounting. Application architecture consists of several main and supporting applications, all application are web-based. The main application consists of sales information systems, purchase information systems, production information systems, ISPM#15 information systems, container checker information systems, IT information systems, HRD information systems, and financial and accounting information systems. Technology architecture uses a client/server architecture pattern with data services Service Oriented Architecture (SOA).

Abstract

Students of Informatics need to understand about the parts of the Internet network and within their own Internet network with certain routing protocol methods so that the data packets sent become more clear and the routing protocol can find the lightest route in sending the data packets to the destination address. Routing Protocol itself is a process to determine the fastest path and advantageous location towards the intended search. One of the routing protocols currently used is the EIGRP (Enhanched Interior Gateway Routing Protocol) method not all students understand about this material. With this problem the authors create a website that concerns the EIGRP Routing Protocol.This website serves to help understand the students about Routing Protocol, especially EIGRP. The website has materials, quizzes, and simulators aimed at helping students to deepen how the EIGRP Routing Protocol works.Results resulting from this Website are students can better understand about EIGRP Routing Protocol by implementing simulator on Website. Simulator can check IP, subnet, and AS EIGRP well. Access to search the database on Admin can be in various formats is CSV, Excel, and PDF.

Abstract

Sebagai mahasiswa jurusan informatika materi yang akan dipelajari oleh mahasiswa sebagian besar akan dilaksanakan di laboratorium untuk keperluan praktek atau uji coba. Untuk mengakomodasi hal tersebut pihak universitas harus menginstall berbagai macam software yang berhubungan dengan materi yang akan diajarkan kepada mahasiswa. Hal tersebut memakan cukup banyak waktu dan tidak praktis karena semua software yang akan digunakan harus di install secara manual satu per satu. Untuk mengatasi masalah inilah maka distro linux khusus untuk keperluan laboratorium informatika diperlukan.Program berupa distribusi linux yang sudah di isi dengan berbagai macam software dan yang diharapkan akan mampu menunjang proses belajar mengajar di laboratorium informatika.Dari pengerjaan skripsi yang telah dilakukan dapat ditarik kesimpulan bahwa Pembuatan distribusi linux secara khusus sangat membantu dalam membuat sebuah enviroment yang spesifik karena seluruh software yang diperlukan sudah berada didalam satu tempat dan penggunaan linux sebagai operating system utama akan sangat membantu menekan biaya operasi dari sebuah perusahaan atau lembaga karena linux bersifat open source.
