Packets with TCP flags set

[".\\lgp" <lgpmsec () gmail com>]

Hi list,

I have a host that responds to a TCP SYN packet with at least one of the
following flags set with a SYN ACK packet: RST, FIN, ACK, FIN|PSH. Two
questions come to mind:
1- is this a bad thing? If so, why?
2- how to mitigate this issue?

Thank you,
Lgp.
