Hello, I'm working for a company which develops since "ages" a client-server application: Windows/UNIX Java or Perl written clients are connecting to defined TCP ports where C/C++ written servers are doing LISTEN and serving the connecting clients. The designed protocol is human readable and an example is in clear text (normally SSL is used to protect the data against network sniffing) here: http://www.unixarea.de/slnp.txt What I'm looking for is some (hopefully FreeBSD) software to harden the server side against attacks of all kind of buffer overflow, SQL injection, etc. Any ideas? matthias -- Matthias Apitz, guru@unixarea.de, http://www.unixarea.de/ +49-170-4527211 +49-176-38902045 "Wenn der Mensch von den Umständen gebildet wird, so muß man die Umstände menschlich bilden."
