IntrusionResistant

A system is called "intrusion resistant", if it, as a whole, continues to adhere to it's predifined rules even in case of a part of the system components violate these rules (accidentally or by malicious intent).

The aim of intrusion resistance is to counter-ballance for the consequences of continued operation of an embraced device under violation of normaly system-guaranted assumtions (e.g., forged data, access rights).

Known ways to achieve that goal are tamper proofed hardware and systems based on ByzantineAgreement.

Remark: Eventually there is no such thing like tamper proofed hardware, just more complication to do so.
