The  security should be commiserate with the value of the assembly.

One  customer mechanically removed any programmed device before it left  the
building even it it destroyed the PCA, +$30k each.

Another added  iron oxide to the potting to obscure the PCA.

If the device ends up  intact in the hands of someone willing to spend the
time and money to  reverse engineer it. It will be reverse engineered.

Using fake  counterfeit chips, loops that erase programs, obscuring schemes,
highly  engineered customised devices can all be defeated.  What is is  
worth?
There are legendary stories of a number of reverse engineered  devices.
Including PCB's with poorly incorporated EC's on the original  showing up in
the counterfeitt.

Is there a way to keep the device  out of the unintended hands?





Larry is exactly right.  If time and money exist to do the work, then  the 
reverse Engineering will happen.
