This research developed an Intranet-Based Wiki with Instant Messaging Protocol (IBWIMP) for the Staff of the Department of Computer Science, University of Nigeria, Nsukka to enable them to collaborate on tasks; like writing of documents like, memo, project guidelines, proposal/grants, and circulars with online security consideration. The essence of this work is to improve on the contributions staff make during work, in carrying out tasks with their colleagues irrespective of the person’s location at that point in time. The existing system on ground would always require the presence of the staff within the department before they can carry out the tasks meant for them or respond to the available mails within their mail boxes located within the general office of the department. In regard to such situation, there is always delay in the processing of such mails or documents that could require urgent attention of the supposed staff therefore could cause serious damages. This research established a better internet connection for the security of the system and the documents therein by the use of virtual private server (VPS) hosting on virtual private network (VPN). This system allows the collaboration between the staff of the department and external persons, or partners classified as external staff user on documents like circulars that normally come from outside the department. This system automatically sends emails to the supposed users whenever the admin posts a document via the Short Message Transfer Protocol (SMTP). The system is accessed online by the users from any location once there is accessible internet connection and users can collaborate on the development of any posted document at the same time. This application was designed using Object Oriented Analysis and Design Methodology (OOADM) and implemented using Hypertext Markup Language (HTML), JavaScript, Cascading Style Sheet (CSS), CkEditor, Hypertext Pre-Processor (PHP) and MySQL database management system.

VoIP (Voice over Internet) dikenal juga dengan sebutan IP (Internet Protocol) Telephony saat ini semakin banyak digunakan karena memiliki beberapa keunggulan, salah satu diantaranya yaitu tarif yang jauh lebih murah daripada tarif telepon tradisional sehinggapengguna telepon dapat memilih layanan tersebut sesuai dengan kebutuhannya. VoIP dapat mereduksi biaya percakapan sampai 70%. Selain memiliki beberapa keunggulan di atas,VoIP juga memiliki kelemahan yang sangat vital yaitu dari segi keamanan transfer suarakarena berbasis IP, sehingga siapapun bisa melakukan penyadapan dan perekaman terhadap data VoIP. Ganguan yang terjadi pada sistem VoIP ada berbagai macam diantaranya, transferdata yang lewat pada suatu jaringan seperti misalnya dapat disalahgunakan (abuse), dapatdibajak isi data tersebut (sniffing), dan tidak dapat mengakses server dikarenakan server yang kelebihan muatan (Denial of Services).Ada beberapa cara untuk mengamankan komunikasi data VoIP, antara lain, dengan mengamankan jalur yang digunakan pengguna untuk melakukan komunikasi VoIP denganmenggunakan metode VPN (Virtual Private Network) dan juga dapat dilakukan suatu metode kriptografi pada aplikasi VoIP tersebut sehingga data yang dikirimkan dapat dilindungidengan baik. VPN adalah teknik pengaman jaringan yang bekerja dengan cara membuat suatu tunnel sehingga jaringan yang dipercaya dapat menghubungkan jaringan yang ada diluar melalui internet. Titik akhir dari VPN adalah tersambungnya Virtual Channels (VCs)dengan cara pemisahan. Kenyataannya koneksi sebuah end-to-end VPN tergantung dari sebuah nilai dari hubungan daripada titik-titiknya. VPN mempunyai dua metode dalampengamanan yakni IPSec dan Crypto IP Encapsulation (CIPE). Selain itu dapat dipergunakan teknik Kriptografi (cryptography) yang merupakan ilmu dan seni penyimpanan pesan, data,atau informasi secara aman.Sistem VoIP menggunakan VPN ini diharapkan dapat memberikan keamanan transfer data pada jaringan internet maupun intranet.

Akhir-akhir ini sudah mulai banyak perusahaan yang memanfaatkan protokol Virtual Private Network (VPN) sebagai media akses/komunikasi antar jaringan interlokal. VPN adalah sebuah protokol keamanan jaringan yang dapat digunakan sebagai salah satu cara untuk meningkatkan keamanan jaringan dari sisi transmisi data. Dengan pemanfaatan VPN, koneksi antar jaringan dapat terbentuk secara virtual walaupun tidak terbentuk secara fisik. Selain itu, dengan memanfaatkan protokol VPN, user (client) dapat mengkases Server secara private melalui jaringan public. Dengan demikian komunikasi antara Client dan Server terjaga dari Sniffing (penyadapan) dari pihak yang tidak bertanggung jawab. Akan tetap tingkat keamanan yang dihasilkan dari penerapan VPN ini perlu dilakukan pengkajian yang lebih dalam. Sehingga tingkat keamanannya dapat diketahui apakah sudah termasuk dalam kategori aman ataukah masih ada peluang bug yang membahayakan dari penetrasi. Dalam penelitian ini dilakukan pengujian Scanning dan Sniffing pada penerapan VPN menggunakan toos hacking yaitu Nmap dan Wireshark. Sedangkan pengujian performansi service pada VPN Server, dilakukan pengujian Denial of Service (DoS) menggunakan tools hacking yaitu LOIC. Adapun objek penelitian ini adalah perangkat Mikrotik RouterOS yang digunakan pada Universitas Teknokrat Indonesia. Hasil penelitian yang didapatkan bahwa komunikasi data antar jaringan (antara VPN Server dan VPN Client) dapat terenkripsi dengan baik. Akan tetapi dari segi konektifitas antar jaringan sangat dipengaruhi oleh performansi bandwidth yang digunakan oleh sistem jaringan tersebut. Selain itu berdasarkan hasil pengujian performansi service pada VPN Server didapatkan hasil bahwa service pada VPN Server dapat dimatikan pada request (ping) sebesar 1.899.276 request. Hal ini dipengaruhi oleh spesifikasi perangkat Mikrotik RouterOS yang digunakan. Adapun untuk penelitian selanjutnya perlu dilakukan pengujian performansi konektifitas menggunakan bandwith yang lebih besar dan untuk menguji performansi service VPN Server menggunakan spesifikasi perangkat Mikrotik yang lebih baik.
