Verify the "vsftpd" package is installed:
# rpm -qa | grep -i vsftpd
vsftpd-3.0.2-22.e16.x86_64

If the "vsftpd" package is not installed, this is Not Applicable.

Find if logging is applied to the ftp daemon.

Procedures:

If vsftpd is started by xinetd the following command will indicate the xinetd.d startup file.

# grep vsftpd /etc/xinetd.d/*

# grep server_args [vsftpd xinetd.d startup file]

This will indicate the vsftpd config file used when starting through xinetd. If the [server_args]line is missing or does not include the vsftpd configuration file, then the default config file (/etc/vsftpd/vsftpd.conf) is used.

# grep xferlog_enable [vsftpd config file]

If xferlog_enable is missing, or is not set to yes, this is a finding.
