Abstract: A storage device is provided. The storage device is connected to a debugging host and includes a nonvolatile memory device; a storage controller configured to control the nonvolatile memory device; and a secure debugging manager configured to count a number of times that a password input from the debugging host and a registered password are mismatched and to block access of the debugging host based on the number of times reaching a threshold count, the storage controller being further configured to store the number of times in the nonvolatile memory device and provide the number of times to the secure debugging manager.
