keys—that is, an Authentic Host. The host can use Command 0x15 - Get / Set Security Level (MAC)
to determine the device’s current security level.
4.5 Command Behaviors By Security Level
Table 4-1 shows the commands that are affected by the device’s security level. Commands that are not
affected by the security level are not listed. The key is as follows:
 Y means the command can run at the specified security level.
 N means the command is prohibited at the specified security level.
 C means the customer may specify Y or S for that command when ordering.
 S means the command is secured [may require MACing, see section 4.1 About Message
Authentication Codes (MAC)].
 * indicates Command 0x02 - Reset Device has special behavior. If an Authentication sequence has
failed, only a correctly MACed Command 0x02 - Reset Device (MAC) can be used to reset the
device. This is to prevent a dictionary attack on the keys and to minimize a denial of service (DoS)
attack.
