ABSTRACTIntrusion Detection System (IDS) is a software that can detect suspicious activity in a system or network . IDS can inspect inbound and outbound traffic in a system or network, analyzing and searching for evidence of trial intrusion. Implementation of IDS on the server using social networking (facebook, twitter, and whatsapp) as notification media makes it easy for administrators identifying infiltration attempt by parties who are not responsible. Social networking on a system is built to serves to provide notifications to administrators as soon as possible when an attack occurred on the server. A message sent contains the IP address of hosts are detected by the system. Client later attacks by IDS snort stored into a MySQL database , at the same time in automatic trigger will run iptables already defined and send notifications to social networks based on the type of attack that performed by the intruder. Based on the test, the system is capable to processing output data from Snort IDS and it can also recognize all activities conducted an intruder in attempt to infiltrate into the system by using the ping flood, syn attack, port scanner, the SSH and FTP based on rules has been applied. Then do the blocking of IP addresses that are considered as intruder after that the system will provide a report to the administrator through social media and web monitoring of the presence of an intruder who trying to get into the system.Keywords: IDS, snort, social networking

ABSTRACTÂ Â Â Â Â Â Department of Transportation, Communication and Information of Manggarai Regency, is one of the instance of Regional Government of Manggarai, NTT, which is responsible to help the Head of Region concerning transportation, communication and information affairs. The lackness of human resources which was competent in computer networking, the high cost of VSAT IP Broadband internet service and maintenance cost of networkâs backbone which is wireless based, have been becoming a problem to the Department concerning their main duties. As an impact, it is necessary to the Department to change their networkâs backbone to wired network based, using VLAN. VLAN can divide network into several segments with low cost implementation. The using of VLAN Trunking Protocol (VTP) will ease the network administrator in managing VLAN.Â Â Â Â Â Â Â Â Â Â The VLAN design in this study used hierarchical model. The logical layer for data distributing was divided into two layers, core/distribution and access layer. Routing between VLANs used ârouter-on-a-stick using trunkâ model, so that the workstations which were owned by different VLAN can communicate each other by using one router only. By using simulation method for testing the design, it was discovered that all workstations between different VLAN have been successfully connected each other and all servers were well-functioned.Â Â Key words : VLAN, VTP,Â hierarchical, router-on-a-stick using trunk

Gedung baru Kampus III IST AKPRIND terdiri dari 5 lantai dengan 30 ruangan yang digunakan untuk kegiatan administrasi dan perkuliahan memerlukan akses jaringan dan internet untuk layanan administrasi dan akademik. Masalah yang dihadapi ketika membangun jaringan nirkabel adalah diperlukan banyak Access Point (AP) untuk menjangkau seluruh ruangan di gedung tersebut. Untuk menghemat jumlah AP, maka digunakan Virtual Access Point (VAP). Penelitian ini bertujuan untuk mengimplementasikan VAP dalam perancangan jaringan nirkabel di gedung baru Kampus III IST AKPRIND, yang disertai pula dengan manajemen bandwidth. VAP merupakan sebuah fitur pada Router Mikrotik, yang digunakan untuk membuat lebih dari 1 SSID dengan menggunakan 1 antarmuka nirkabel fisik. Dengan begitu kita bisa memiliki beberapa SSID yang berbeda dan memiliki layanan yang berbeda pula. Hasil pengujian jaringan Multiple SSID untuk setiap user Mahasiswa yang melakukan login hotspot akan mendapatkan bandwidth sebesar 512KBps untuk AP Fisik. Sedangkan bandwidth yang diberikan untuk VAP sebesar 4MB dibagi rata sebanyak user yang terhubung ke jaringan. Hasil perbandingan kinerja AP fisik dan virtual menunjukkan bahwa kinerja jaringan fisik lebih bagus dibandingkan dengan kinerja VAP.
