SUB-BAB 01 KONSEP

KONSEP FILE SHARING

Apa Itu File Sharing?

File sharing adalah proses berbagi file atau direktori antara komputer dalam jaringan. File sharing memungkinkan multiple user untuk mengakses, membaca, menulis, dan berbagi file dari lokasi yang berbeda dalam jaringan.

Protokol File Sharing

PROTOKOL	OS	PORT	USE CASE
SMB/CIFS	Windows, Linux, macOS	445 (TCP)	File sharing Windows/Linux
NFS	Linux, Unix	2049 (TCP/UDP)	File sharing Linux/Unix
FTP	All OS	20-21 (TCP)	File transfer
AFP	macOS	548 (TCP)	File sharing macOS
WebDAV	All OS	80, 443 (TCP)	Web-based file sharing

Arsitektur File Sharing

FILE SHARING ARCHITECTURE

Server: Menyimpan file dan menyediakan akses ke client

Client: Mengakses file dari server

Share: Direktori atau file yang dibagikan

Permission: Hak akses ke share (read, write, execute)

Authentication: Autentikasi user untuk akses share

Security Considerations

AUTHENTICATION

Autentikasi user untuk akses share

ENCRYPTION

Enkripsi data saat transfer

PERMISSION

Hak akses ke share

TIPS: Gunakan SMB3 dengan encryption untuk keamanan maksimal. Gunakan permission yang tepat untuk mengontrol akses ke share. Gunakan authentication untuk mengontrol siapa yang bisa akses.
