TMA-SOLARIS-7.4
Set Default File Creation Mask for FTP Users
Description
If FTP is permitted, set a strong, default file creation mask to apply to files created by the FTP server. Many users assume that the FTP server will use their system file creation mask; generally it does not. This setting ensures that files transmitted over FTP use a strong file creation mask. Audit: only evaluated where the FTP server is installed.
How it is checked
Audit method: File pattern
- File
/etc/proftpd.conf- Pattern
(?m)^Umask\s+0?27\b
