Subject:   looking for software to harden TCP/IP client-server application
Message-ID:  <20150521060204.GA2203@c720-r276659>

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:

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,

Any ideas?
