When integrating the Galileo API with a travel booking system, the following security protocols should be in place:

1. Data Encryption: Use strong encryption methods (e.g., TLS/SSL) to protect data transmitted between the API and the booking system.

2. Authentication and Authorization: Implement robust authentication and authorization mechanisms to ensure that only authorized users and systems can access the API.

3. API Keys and Tokens: Use API keys or tokens for secure access and to manage permissions.

4. Regular Security Audits: Conduct regular security audits and vulnerability assessments to identify and address potential security issues.

5. Error Handling and Logging: Implement comprehensive error handling and logging mechanisms to monitor and respond to security incidents.

6. Compliance with Standards: Ensure compliance with relevant data protection standards and regulations, such as GDPR or CCPA.

In summary, security protocols include data encryption, authentication, API keys, regular audits, error handling, and compliance.
