Gabby has been assigned to assess the security of smart meters. What is NOT a common concern for an embedded system like a smart meter?

Embedded systems like smart meters typically do not include a SQL server to attack, making SQL injection an unlikely issue. Gabby should focus on securing the traffic from his meter, ensuring that denial-of-service (DoS) attacks are difficult to accomplish and that remotely disconnecting the meter using exposed administrative interfaces or other methods is prevented.
