On my website I am able to access my phpMyAdmin control panel by typing in the ip address followed by /phpmyadmin e.g.
http://18.129.514.29/phpmyadmin/ (note: not my real ip)
I also need to limit access to SSH, currently all you need to do to get access to the server login screen is type the ip address of the server which anyone can get a hold of by pinging the server.
What measure can I take to make sure these issues do not become a security threat?
