To validate that the architecture of your complex, multi-system integration will meet security standards, follow these steps:
1. **Document the Architecture**: Create detailed diagrams showing data touch points, information flows, authentication, authorizations, and security controls.
2. **Inventory Third-Party Libraries**: Keep a list of all third-party libraries and their versions used in your solution.
3. **Perform Security Testing**: Test the entire solution using manual and automated security tools. Include all external endpoints, ensuring secure data and credential transfers.
4. **Run Automated Scans**: Use tools like Salesforce Code Analyzer and DAST scanners to identify vulnerabilities. Address flagged issues and document false positives.
5. **Follow Security Guidelines**: Adhere to Salesforce security standards, including CRUD/FLS checks, input validation, and mitigation of vulnerabilities like CSRF and SQL injection.
6. **Obtain Third-Party Permissions**: Secure permissions for testing external endpoints and follow Salesforce's IP and domain guidelines.
7. **List Sensitive Data**: Document all sensitive data processed or stored, including storage locations and third-party data-sharing practices.
8. **Engage in Security Review**: Submit your solution for a security review to evaluate vulnerabilities, architecture, and best practice adherence.
9. **Provide Documentation**: Include test environments, scan reports, false-positive documentation, and solution documentation in your submission.
10. **Iterate and Improve**: Address findings from the security review and resubmit if necessary.
These steps will help ensure your architecture meets security standards and minimizes risks.
