chmod
 

The answer depends slightly upon how you have SAMBA set up, but

Assuming that you are locally authenticated and these are under your home folder, you depend upon and live in 'cmod land'! If 'chmod 700' makes them unavailable over the samba share, then you are not being authenticated using your linux account properly. Most folders I have set "chmod 751", but suit yourself, just make sure that the FIRST digit is 7 so that you have maximum personal rights over your personal folders.
