### Implementing the Code
For a practical implementation of the code above:

- Ensure to replace dummy and mock functionality with actual logic suited to your application's architecture and security requirements.
- The secure plugin loading function (`load_secure_plugin`) and decision-limiting wrapper (`limit_decision_making`) provide basic templates; customize them based on the specific security considerations and operational requirements of your plugins and decision-making processes.
- Regularly review and update your security practices, including encryption methods and key management strategies, to adapt to evolving cybersecurity threats and standards.

By integrating these practices into your development and security processes, you can address the identified vulnerabilities in LLM applications, enhancing both security and reliability.


### Recommended Automated Validation Tools

For the vulnerabilities addressed, the following automated tools can be integrated into your development and deployment pipelines:

- **OWASP ZAP**: Automate web application security testing.
- **Bandit**: Integrate into CI/CD pipelines for automatic scanning of Python code for security issues.
- **SQLMap**: Use in automated testing environments to check for SQL injection vulnerabilities.
- **PyCQA/flake8**: Integrate into your development process for continuous code quality and security checks.
- **TensorFlow Privacy**: Use for training machine learning models while preserving privacy, to mitigate the risk of training data poisoning.

Incorporating these tools and practices will help enhance the security posture of applications using LLMs against the identified vulnerabilities and align with best practices in cybersecurity.
