Option 2: Incorrect. A firewall is a network security device that monitors and filters incoming and outgoing network traffic based on predetermined security rules. While it plays a role in data security, it is not a principle of data security.

Option 3: Incorrect. An Intrusion Detection System (IDS) is a device or software application that monitors network or system activities for malicious activities or policy violations and produces reports. While it plays a role in data security, it is not a principle of data security.
