Ensure no users have .netrc files
Mô tả
The .netrc file contains data for logging into a remote host for file transfers via FTP. The .netrc file presents a significant security risk since it stores passwords in unencrypted form. Even if FTP is disabled, user accounts may have brought over .netrc files from other systems which could pose a risk to those systems.
