How our Open Ports assessment is performed
The Ceeyu port scanning service first enumerates all open ports. In addition, will determine the service listening on the open ports. If we detect services behind these open ports for which open ports are not recommended (such as FTP, SFTP, Private Printer Service, TACACS(+), NetBIOS, IRC, LDAP, MS-DS, MSSQL, MySQL, RDP, PostgreSQL, VNC, Bittorrent Tracker, MSRPC, TFTP, Syslog, and SNMP), this has a negative impact on your rating.
