In an ambush game, the ambusher need succeed only once, the ambushee always. The best security is a society which doesn't promote ambush attacks, whether out of general respect, lawfulness, or a belief in institutional mechanisms (business practices, fair marketplaces, civil and criminal courts, penal systems). Attempting to bolt on security where such a society doesn't exist is quite fraught. The attempts will likely be expensive and lossy.
