Implementasi Port Forwarding Untuk Keamanan Data Server (Studi Kasus: Dinas Pendidikan Kab. Pasuruan)
Keywords:

District Education Office. Pasuruan has a windows-based website application that uses Windows server 2008. The server was hijacked by hackers by changing the database configuration and changing the website display script. Hijacking occurs because of the large number of open ports that are not used on Windows Server 2008. The more open ports, the more vulnerable the server is to penetrate. Even after installing a firewall on Windows Server 2008, hackers can still penetrate it. This can be overcome by migrating to a new server, but it cannot be done because the server is connected to the Windows-based Central Ministry server for the sake of data decentralization. To overcome this problem, Windows Server 2008 is paired with a Linux server as a firewall router that is configured using the port forwarding method. The results of the study show that port forwarding can provide security on Windows Server 2008. Clients from outside networks cannot access Windows Server 2008 directly, so clients cannot find out the original IP address or open ports which can be a gap to penetrating the network. Windows server 2008. Clients from the network can access website applications on Windows server 2008 through an intermediary router.
