Abstract

At the beginning, PT Layar Sentosa Shipping Corp. do data transaction through e-mail via the internet without any security, until at some point there was an e-mail that can be read by unauthorized parties. Therefore, since January 2012, the company decided to use a method of a Virtual Private Network (VPN) to secure data traffics and e-mails. In this study, conducted testing of the VPNs implementai. Tests are conducted to test network connectivity to the parameters of packet loss, round trip time and transfer files via FTP. Furthermore, testing the level of VPN security with offensive (attacking) the method of Denial of Service (Dos), Man-in-the-Middle (MITM) with a sniffer application and hacking with Linux applications Bactrack. Results of experiments testing the connectivity to the conclusion that the bandwidth is the main factor that determines the merits of inter-office network connectivity. In experiments testing the VPN security, attack (attacking) with Denial of Service (DoS) was successfully turn off the service or services on the VPN server. In addition, the tapping test (spoofing) successfully read the data communication between the client and the VPN server. And lastly, hacking to get a username and password by using the tools available on Backtrack Linux applications also broke through the client login access to the VPN server.
