Abstract

TCP SYN Flood as one kind of Denial of Service (DoS) attack, still popular to flood the server connection, by sending SYN packets to the target. Because of the risk caused by this attack, there is a need for a network security mechanism. In this paper, one of the security mechanisms proposed is using Stateful Packet Inspection (SPI) method on Configserver Security and Firewall (CSF). By using SPI method, CSF has capabilities to responsible for separating packets of data, that may be entered with data packets that should not be entered into the server. For example: port to be opened, port closed, and IP Address that may access the server for anywhere. This paper combines both of CSF and SPI method to prevent TCP SYN Flood (DoS) with Proof of Concept (PoC) at the Linux operating system. The security process is done in 3 ways: configuring a maximum connection from an IP Address to a server, securing an incoming SYN packet per second, and counting how many times an IP Address violates the minimum SYN packet rule per second before being blocked by a firewall.

Abstract

The development of computer network technology in the form of Software Defined Networking (SDN), provides many facilities for users to be able to develop network control applications, which can separate the data plane function from the control plane. The existence of this separation on routers and switches makes it easy for developers to centrally develop software and devices according to what is needed by users. However, there were obstacles to implementing SDN on IP networks in a short time. For this reason, it is necessary to implement SDN in stages by adding SDN to the existing IP network in the form of SDN IP, so that SDN can be connected and exchange routing information autonomously. This study focuses on the design and implementation of SDN IP using the Open Network Operating System (ONOS) on the Border Gateway Protocol (BGP). The results show that the design and implementation of SDN IP based on ONOS and BGP can be done well, where SDN can connect and exchange routing information with the Autonomous System (AS) native BGP-based network. Key word(s): Autonomous System (AS) Border Gateway Protocol (BGP) Open Network Operating System (ONOS) Software-Defined Networking (SDN) SDN IP

Abstract

The development of information technology and computer network from time to time is increasing along with the increase in user needs for both from the business, education, industrial, to data security side. Data of network traffic that is getting denser in communication and data exchange between users on computer networks can become a problem when using conventional computer network technology. For that, it needs a new technology that is implemented in computer networks, along with the measurement of Quality of Service (QoS) in it. Software-Defined Networking (SDN) is a solution for this, where the stages of network design, management and implementation, separate the data plane and the control plane. In this research, the implementation of SDN was carried out in the form of a simulation using both of Mininet and OpenDaylight with a Tree Topology, then the QoS measurements were carried out in it. The results of testing and measuring QoS on SDN simulations with Tree topology using Mininet and OpenDaylight, showed a Jitter value of 0.425 ms, a Packet Loss value of 0.266%, a Bandwith value of 9.3925 Mbps, a UDP Throughput value of 2.348 bits/sec, and a TCPThroughput value of 2.335 bits/sec.

Abstract

The Linux Operating System is known for its open-source characteristic which means everyone is free to develop Linux with the use of available source code. The result of Linux development is called Linux distribution (Distro). There are various Linux distributions in accordance with their respective uses, one of them is Kali Linux. Kali Linux is a Linux distro that is developed to penetrate the security of computer systems. Kali Linux uses a variety of tools to perform its functions. However, for users who want to use the functionality of Kali Linux without having to change the Linux distro that has been used, the user can use Katoolin. Katoolin can provide the convenience and flexibility for users who want to use Kali Linux as a special Linux distro for the purpose of penetrating computer system security without having to replace the distro that has been used or do a full install of Kali Linux. One case study that can be solved using the Kali Kali Linux based tool on Katoolin is Reverse Engineering. The case study was solved using one of the tools in the Reverse Engineering category named apktool that available on Katoolin.

Abstract

NDN (Named Data Networking) is one of today's internet technologies with identifier of the packet is given in the form of a content name, not a source or destination address. Such properties make NDN have a new forwarding mechanism and different from host to host (IP-based) network architecture. Utilization of this new technology is usually incomplete or there is a need for simulations for initial testing and testing. This paper will discuss about NDN simulation. The simulation will be done using ndnSIM, an open source simulator and testing was performed at Information Technology Campus, Faculty of Engineering, Udayana University’s intranet.

Abstract

The development of business in this globalization era has led to increasingly a competition, the application of IT in business today isn’t enough, therefore a company needs enterprise resource planning (ERP) to keep the company's cycle spinning amid global competition. Now ERP not only be applied to large companies,UKM/UMKM Currently can use ERP to run the business process. Unfortunately, the company doesn’t understand the importance of ERP and the benefits of ERP, including CV Rumah Indah, a home interior company, which is a case study in this journal. CV Rumah Indah still applies conventional business processes which are all done manually. Even though in practice the business owner encounters several obstacles in the distribution of raw materials, the distance between the production house and the supplier, and there is one raw material that is difficult to obtain if supplier’s stock runs out so the company must be waiting till the materials available. It takes the business owner have to go back to the supplier to take orders for the raw material that was ordered on the previous visit, besides that the interior production time becomes delayed. Therefore, the author took initiative to provide a solution of the problems faced by business owners, the solution is applying the purchase module on ERP using the open source ERPNext software. Hope that implementation of ERP being able to help in the effectiveness and time efficiency when purchasing raw materials to suppliers.

Abstract

The development of technology, especially information technology has developed very quickly. One of the technologies of this development is the internet. The use of the internet is very helpful in distributing information because it can be accessed anywhere and anytime. However, freedom in using internet access can also be misused and has a negative impact. An example is accessing websites that are dangerous or not suitable to be accessed. Therefore, it is necessary to guarantee the use of the internet that is equipped with a system that can filter negative sites so that they cannot be accessed freely. The solution that can be applied is the use of proxy server technology that can perform access management on the internet. The proxy server will be implemented using the ClearOS operating system ver.7 that has been installed on the server computer. The result of implementing a proxy server based on ClearOS is that it can manage access to sites that should not be accessed by the client computer.
