No, TCP FIN scan is another method to see what all ports are open. So your firewall denied those and hence the message.
If you need more information, provide some more details as to what network, firewall, what is the exact log etc.
If you just google, you'd get thousands of page probably on this topic.
But I suggest you to read this to get some solid info on how this works;
