PENGEMBANGAN SISTEM FIREWALL PADA JARINGAN KOMPUTER BERBASIS MIKROTIK ROUTEROS

Keamanan jaringan sangat penting dalam menjaga kerahasiaan, integritas, dan ketersediaan data. Firewall adalah salah satu alat penting untuk meningkatkan keamanan jaringan komputer. Mikrotik RouterOS adalah sistem operasi jaringan populer yang menyediakan fitur firewall yang lengkap. Namun, untuk mengoptimalkan penggunaan firewall pada Mikrotik RouterOS, diperlukan sistem firewall yang lebih kompleks. Penelitian ini bertujuan untuk mengembangkan sistem firewall yang lebih kompleks pada jaringan komputer berbasis Mikrotik RouterOS. Metode yang digunakan adalah dengan menganalisis kebutuhan keamanan jaringan komputer, mengidentifikasi dan menganalisis fitur firewall yang tersedia pada Mikrotik RouterOS, dan merancang sistem firewall yang lebih kompleks dengan memanfaatkan fitur-fitur tersebut. Hasil penelitian menunjukkan bahwa sistem firewall yang dikembangkan dapat meningkatkan keamanan jaringan komputer secara signifikan. Sistem firewall tersebut terdiri dari beberapa konfigurasi firewall seperti blokir akses ke jaringan internet, blokir akses ke jaringan lokal, pembatasan bandwidth, dan lain sebagainya. Selain itu, sistem firewall juga dilengkapi dengan fitur monitoring dan logging untuk memudahkan pengguna dalam memantau akses jaringan komputer. Kesimpulannya, sistem firewall yang dikembangkan dapat meningkatkan keamanan jaringan komputer berbasis Mikrotik RouterOS. Penelitian ini dapat memberikan kontribusi dalam pengembangan sistem keamanan jaringan komputer menggunakan Mikrotik RouterOS

Penyebab Perubahan Ketebalan Carotid Intima-Media

Atherosclerosis causes significant morbidity and mortality. Carotid intima-media thickness (CIMT) can predict the onset of cardiovascular and ischemic stroke in the future. CIMT, the measurement of atherosclerosis, is determined in vivo using carotid ultrasound. CIMT is associated with traditional cardiovascular risk factors such as age, sex, race, smoking habits, alcohol consumption, exercise habits, blood pressure, dyslipidemia, dietary patterns, medications used, glycemia, hyperuricemia, anthropometric parameters associated with obesity. In addition, CIMT is also associated with novel risk factors, ie genotypes, cardiovascular anthropometry parameters, rheumatoid arthritis, immunologic diseases, inflammatory cytokines, lipid peroxidation, chemocyte anthropometric parameters, infectious diseases, vitamin D, matrix metalloproteinases, and other disease

PERAN DAN STRATEGI LEMBAGA KEUANGAN SYARIAH (STUDI KASUS) BMT SYARIAH ATTAQWA & BMT IKHTIAR

AbstractThe aim of this research is to know the role and Strategy of syaria cooperation as a finance institution in Indonesia. The research object are BMT At-Taqwa and BMT Ikhtiar. The research method used in this research are qualitative research, descriptive analysis by interviewing some of employees.  By  using  data  collection  technique  such  as  interviewing  and observing primary informant (BMT At-Taqwa and BMT Ikhtiar Management) and secondary informant (Sharia  Supervisory Council) for data validity.The result of this research showed that there were many fungtions from syaria cooperation to help people in Indonesia based on Islamic rules. Those adjustments can be seen from the steps   of sharia strategic management  taken from islam rules start   from   strategy   formulating,   strategy   implementing,   and   strategy evaluating. The indicators of this research are the process of strategic management done by BMT At-Taqwa and Ikhtiar adjusted to J. David Hunger concept and Thomas L.Wheelen by looking forward from the evaluation. Keywords : Sharia Cooperation, Finance Institutio

Technical and Human Issues in Computer-Based Systems Security

Computer systems and internet are becoming pervasive in our everyday life. Being online brings the consequence that such systems are prone to malicious attack. This vulnerability, along with our reliance on these systems, implies that it is important for us to do our best in securing them to ensure their proper functioning. In this paper, we are trying to tackle the security issues from both technical and human perspectives. From this dual standpoint, we hope to obtain a better understanding on how computer attacks are performed, including how to gain illicit access, the types of attacks, as well as the potential damage that they can cause. We also uncover sociological and psychological traits of the attackers, including their community, taxonomy, motives and work ethics. This survey paper will not provide a concrete solution on how to secure computer systems, but it highlights the socio-technical approach that we must take in order to obtain that goal

Automatic Generation of Distributed System Simulations from UML

Nowadays, an object-oriented approach is commonly used for building computer systems. The benefits of the object-oriented method, such as scalability, stability and reusability, make this method suitable for building complex systems, including those in the distributed system area. A distributed system application usually needs to satisfy quite stringent requirements such as reliability, availability, security, etc. and the cost of building such an application will be quite high. It is therefore desirable to be able to predict the performance of the proposed system before the construction begins. In order to do this, it is important to evaluate the requirements of the new system and translate them into a specification (design). The design process helps the system developers to understand the requirements better as well as to avoid misconceptions about the system. From the specification, a simulation program can be built to mimic the execution of the proposed system. The simulation run provides some data about the states of the system and from these data, the performance of the system can be predicted and analysed. UML (Unified Modeling Language) is one example of the object-oriented design methods that has been widely used for specifying system requirements. There are also some object-oriented simulation languages/packages available, for example, SIMULA or C++SIM package, but it is often difficult to transform the system’ s requirements into a simulation program without sound knowledge of some simulation techniques. On top of that, a new simulation program needs to be built each time for different systems, which can be quite tedious. The currently available UML tools do not provide a feature to generate simulation programs automatically from UML specifications. In this paper, we describe a tool for constructing simulation programs in a generic way, based on a simple specification (preferably in a UML notation) by identifying the simulation components and their structure
