Analisa Infrastruktur Jaringan Wireless dan Local Area Network (WLAN) Meggunakan Wireshark Serta Metode Penetration Testing Kali Linux

Computer networks and the internet play an important role for the smooth running of various fields of work. One example of information and communication technology is the Wireless Local Area Network (WLAN) or also called wireless local network technology. The method used in this research is the Penetration Testing method, with the intention of analyzing the Wireless Network computer security system in the STMIK Bina Patria Laboratory. Testing is carried out with several activities, including identifying and exploiting vulnerabilities in computer network security. In analyzing the security of the WLAN network, it is carried out using the Penetration Testing method where a form of attack on the network is simulated, one of the operating systems that has the right specifications in this regard is Kali Linux. Wireless network is a network that is widely used in institutions and public places. Even though it has a security system, wireless networks can still be attacked by attackers

Membangun Jaringan Virtual Private Network (Vpn) Dengan Metode Tunneling Menggunakan Ubuntu 11.10 Pada Laboratorium Jaringan STMIK PPKIA Pradnya Paramita Malang

Local computer network is a computer network that is built on the college STMIK PPKIA Pradnya Paramita Malang and serves as a support learning tool for students. This private network built and designed by an Admin. Admin should always monitor network construction. In order for the construction of the network remains stable. But not forever a network admin will continue to be on a server computer, there are times when an Admin has a personal interest that requires Admin leave his job. It takes a special application that can to remote computers with a remote server.Virtual Private Network or VPN is better known by the tunneling method is implemented on a local network to develop local networks that exist in universities, facilitate an Admin to connect to servers and computers to remote computers with a remote server.VPN has been tested on a local network STMIK PPKIA Pradnya Paramita Malang Ubuntu11.10 operating system. The result of this research is the establishment of a network virtual private network (VPN) with tunneling method in laboratory network Ubuntu11.10 STMIK PPKIA Pradnya Paramita Malang

Some experiences in using virtual machines for teaching computer networks

Laboratory practice is a fundamental aspect of computer network learning. Experiments tend to be very specific, frequently demanding changes in the local network topology and privileged access to the operating system configuration. These features impose a specific and exclusive laboratory for network teaching experiments. However, it is not always possible to provide such laboratory; the reality in most institutions is to have shared laboratories, used by different students and disciplines. This problem can be alleviated by the use of virtual machines, allowing each student to build his/her own network experiment, using the appropriate topology, and thus not disturbing the other activities running in the lab. This paper presents some experiences in using virtual machines to teach advanced aspects of computer networks, such as IPSec, firewalls and network services. Also, some key points are highlighted in order to show the benefits of virtual machines for pedagogical practice.Education for the 21 st century - impact of ICT and Digital Resources ConferenceRed de Universidades con Carreras en Informática (RedUNCI

<Report> An operation of campus information processing network and an extension of academical working environments

At information Processing Center, Nagaoka University of Technology, a star local area network with Port Selector has been working since 1987 April. In 1989 February, an Ethernet local area network (CIP-LAN) and a host computer MV/20000-II have been installed and began to start. Although data communications between personal computers, work stations, and MV/20000-II become increasing, there are some problems which must be solved. We have not only investigated a style of the networking environments at university, but also developed a few of terminal interfaces. This paper describes an installation and experiences on campus computer network which is connected to wide area networks JUNET and N-1 net. Moreover, we discuss about an Ethernet multi interface for personal computer and evaluate the characteristics of a virtual UNIX, MV/UX, which is the operating system for MV/20000-II

A comparative experimental design and performance analysis of Snort-based Intrusion Detection System in practical computer networks

As one of the most reliable technologies, network intrusion detection system (NIDS) allows the monitoring of incoming and outgoing traffic to identify unauthorised usage and mishandling of attackers in computer network systems. To this extent, this paper investigates the experimental performance of Snort-based NIDS (S-NIDS) in a practical network with the latest technology in various network scenarios including high data speed and/or heavy traffic and/or large packet size. An effective testbed is designed based on Snort using different muti-core processors, e.g., i5 and i7, with different operating systems, e.g., Windows 7, Windows Server and Linux. Furthermore, considering an enterprise network consisting of multiple virtual local area networks (VLANs), a centralised parallel S-NIDS (CPS-NIDS) is proposed with the support of a centralised database server to deal with high data speed and heavy traffic. Experimental evaluation is carried out for each network configuration to evaluate the performance of the S-NIDS in different network scenarios as well as validating the effectiveness of the proposed CPS-NIDS. In particular, by analysing packet analysis efficiency, an improved performance of up to 10% is shown to be achieved with Linux over other operating systems, while up to 8% of improved performance can be achieved with i7 over i5 processors
