Notably (and unfortunately), security technology (as used in elections and everywhere else) is generally much better at detecting problems than it is at preventing them.

Cryptographic authenticators can show whether data has been altered, but does prevent alteration. Physical seals can reveal that something was tampered with, but don't prevent the tampering. Prevention requires much more complex protocols and procedures, and generally provides only fragile assurances.
