Security concerns

[Bruce Duncan]

Hi all,
I'm new to this list, so you've probably answered this
question before but....

What are the security issues raised by using Samba?

What I mean by this is can someone break into
my UNIX box through use of samba, SMB, etc.
Can someone write to/mount a shared drive without
permission?


These questions are asked given that I use
security = user
and that I place all NT clients in the access list
for all shares.


P.S. my setup is NT 4.0 SP3 and a Sun Sparc Ultra 
running Solaris 2.5.1


Thanks in advance,
bruce
