What are the key security considerations

Key security considerations in embedded systems include:

1. **Authentication**: Ensuring only authorized users and devices can access the system.

2. **Encryption**: Protecting data during transmission and storage to prevent unauthorized access.

3. **Firmware Integrity**: Regularly updating and securing firmware to prevent exploitation of vulnerabilities.

4. **Access Control**: Implementing proper access controls to restrict permissions and prevent unauthorized actions.

5. **Secure Communication**: Using secure protocols and methods to safeguard data exchanges between devices.

These considerations help safeguard embedded systems against threats and ensure their integrity and reliability.
