Fuzzing tools are the first things I would think of. Because
this is _not_ a web application, tools designed to harden
web-based systems probably don't work here (Burp Suite, for
example).
The ports collection has security/fuzz, security/fuzzdb, and
security/honggfuzz. AFL is also worth lookin at - try if it
compiles on FreeBSD (it's a Linux program). Here's the source:
