Abstract

File Transfer Protocol (FTP) has a weakness because the data sent is not encrypted, making it vulnerable to attacks. This study aims to implement AES-256 encryption on a Debian-based FTP service using FTPS via VSFTPD and OpenSSL. The research stages include serv-er installation and configuration, SSL/TLS certificate creation, FTP account creation, and connection testing using WinSCP. The results show that FTPS was successfully implemented on a Debian server with IP 192.168.10.2. File transfer testing ran well using TLS 1.3 and the TLS_AES_256_GCM_SHA384 cipher so that data is more secure during the transmission process. This implementation has been proven to improve data transfer security by ensuring the confidentiality and integrity of information.
