What is needed to ensure secure file sharing while using Samba?

To ensure secure file sharing while using Samba, encrypted network connections are essential. Samba operates by sharing files and services across a network, often in mixed environments containing multiple operating systems. When data is transmitted over a network unencrypted, it can be intercepted, exposing sensitive information. Utilizing encrypted network connections, such as SSL/TLS protocols, helps safeguard the data during transmission, making it much harder for unauthorized users to access or tamper with it.

While access control lists may help manage permissions for file access once a user is authenticated, they do not protect the data in transit. Using plain text passwords is inherently insecure, as it leaves sensitive information vulnerable to interception since these passwords can be easily captured by anyone with access to the network. Thus, while control measures are important, they do not replace the need for encrypted connections to ensure that the data itself remains secure while being shared.
