You can check the ns source code, manual, and contrib-code web page...
you should find that there is some support for mobile IP,
but I don't know of code for IPSEC or firewalls.

It would be very interesting to study security protocols in ns.
It's just software, so of course you CAN,
but it hasn't been used much in that area, so you will likely need to
develop some infrastructure (it certainly won't be as easy as doing
yet another TCP simulation).
