## Protocol State Machine Security

Protocol state machine security involves protecting the integrity of the sequence of states a protocol passes through during its operation. Every transition between states must be authorized and consistent with the protocol's rules.

If the state machine is compromised, an attacker could potentially force the protocol into an invalid or insecure state. Security analysis involves mapping out all possible transitions and verifying that they are all secure.

This is essential for complex protocols with many interacting parts. By securing the state machine, developers ensure the protocol remains robust against attacks and errors.
