few things what always help. make sure you have atleast all services you run the most up2date version. have them constantly watched by loggers. make sure those logs files get not deleted (even if person get root ;-) ). but this is just handy when you got hacked and you need to find out who did it. also handy is put some firewall (prefered cisco with extreme good configuration) in front of it so you are sure only allowed persons can get on it.

next to all of this passwords are the weakest point of many security things. just make sure that with password guessign people do nto get in (you get now all script kiddies and more wannabe hackers ;-) ). the others use buffer over flow et problems in programs. you can limit this by making sure they get a time out to the server. (ip rejected by firewall).

just a few ideas Smilie

fwb_ipfw

fwb_ipfw(1)							 Firewall Builder						       fwb_ipfw(1)

NAME

       fwb_ipfw - Policy compiler for ipfw

SYNOPSIS

       fwb_ipfw [-vVx] [-d wdir] [-o output.fw] [-i] -f data_file.xml object_name

DESCRIPTION

       fwb_ipfw is a firewall policy compiler component of Firewall Builder (see fwbuilder(1)). This compiler generates code for ipfw - a firewall
       and traffic shaper in FreeBSD (see ipfw(8)). Compiler reads objects definitions and firewall description from the data file specified  with
       "-f" option and generates firewall configuration and activation script.

       The  generated file has a name that starts with the name of the firewall object, with an extension ".fw". It is a shell script that flushes
       current policy, then loads new filter and nat rules.

       The data file and the name of the firewall objects must be specified on the command line. Other command line parameters are optional.

OPTIONS

       -f FILE
	      Specify the name of the data file to be processed.

       -o output.fw
	      Specify output file name

       -d wdir
	      Specify working directory.  Compiler creates firewall activation script in this directory.  If this parameter is missing,  then  all
	      files will be placed in the current working directory.

       -v     Be verbose: compiler prints diagnostic messages when it works.

       -V     Print version number and quit.

       -i     When this option is present, the last argument on the command line is supposed to be firewall object ID rather than its name

       -x     Generate debugging information while working. This option is intended for debugging only and may produce lots of cryptic messages.

NOTES

       Support for ipfw was added in version 1.0.10 of Firewall Builder
