The default umask for FTP users must be 077.

Setting a very secure default value for umask ensures that users make a conscious choice about their file permissions.

The package service/network/ftp must be installed for this check.

# pkg list service/network/ftp

If the output of this command is:

pkg list: no packages matching 'service/network/ftp' installed

no further action is required.

Determine if the FTP umask is set to 077.

# egrep -i "^UMASK" /etc/proftpd.conf | awk '{ print $2 }'

If 077 is not displayed, this is a finding.

The root role is required.

# pkg list service/network/ftp

If the output of this command is:

pkg list: no packages matching 'service/network/ftp' installed

no further action is required. Otherwise, edit the FTP configuration file.

# pfedit /etc/proftpd.conf

Locate the line containing:

Umask

Change the line to read:

Umask 077
