System contracts, system accounts, privileged accounts

There are other system accounts, created by eosio account, which control specific actions of the system contracts mentioned in previous section. Note the terms system contract and system account. Privileged accounts are accounts which can execute a transaction while skipping the standard authorization check. To ensure that this is not a security hole, the permission authority over these accounts is granted to eosio.prods system account.
