Gisteren ben ik in mij mail oof even vergeten te melden dat mod_security
bestaat (voor apache natuurlijk)

Quote:
"ModSecurity is an Apache module that adds intrusion detection and
prevention features to the Web server. In principle it is similar to an
IDS you would use to analyse your network traffic, except that it works
on the HTTP level and understands it really well. Because of this it
allows you to do things that are normal from the HTTP point of view but
are difficult to do from an classical IDS."


Om mogelijke (nog niet bekende) attacks te blokeren dmv mod_security
kan je vb deze extra regels bijvoegen:
SecFilterSelective THE_REQUEST "wget "
SecFilterSelective THE_REQUEST "perl "
SecFilterSelective THE_REQUEST "lynx "
SecFilterSelective THE_REQUEST "ftp "
SecFilterSelective THE_REQUEST "scp "
SecFilterSelective THE_REQUEST "rcp "
SecFilterSelective THE_REQUEST "cvs "
SecFilterSelective THE_REQUEST "telnet "
SecFilterSelective THE_REQUEST "ssh "
SecFilterSelective THE_REQUEST "echo "
SecFilterSelective THE_REQUEST "nc "
SecFilterSelective THE_REQUEST "mkdir "
SecFilterSelective THE_REQUEST "cd /tmp"
SecFilterSelective THE_REQUEST "cd /var/tmp"
