I was using them several times and found people also keen to use them as security measure before implementation :-) It is nice to see SA anyway and know things get improved.. it would be also nice to have a tool that would easily assess the OS state.. I know this is not the goal here and not really the topic.. but could be a nice derivative :-) If we speak about four byte DoS I think this should not be possible in the default configuration anyway.. or at least it would be nice to have a tool that would show the problem and tell you how to fix it.. kind of automated OS hardening.. I am sure this could be done with CIS alike set of rules, no? :-) -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
