Summary of Changes

Hello @Nirvan-Bobde30, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on bolstering the application's security posture by refining its HTTP header configurations within firebase.json. The changes aim to strengthen HSTS implementation and introduce protection against MIME-sniffing attacks, contributing to a more secure user experience.

Highlights

• Security Headers Update: The strict-transport-security header has been updated to include the preload directive, enhancing the application's HSTS (HTTP Strict Transport Security) enforcement.
• New Security Header Added: A new X-Content-Type-Options header with the value NoSniff has been added to prevent browsers from MIME-sniffing content, thereby mitigating certain types of security vulnerabilities.

Code Review

This pull request enhances security by adding the X-Content-Type-Options header and strengthening the Strict-Transport-Security header for the prod, dev, and uat environments. My review includes a correction for the X-Content-Type-Options header value to align with web standards. I've also raised a concern about the same security enhancements not being applied to the *-legacy environments, which could lead to security inconsistencies. Applying these changes consistently is recommended.

[gemini-code-assist]

These security header enhancements are excellent. However, I've noticed that these same improvements have not been applied to the prod-legacy, dev-legacy, and uat-legacy hosting targets within this file. This creates a potential security inconsistency between your environments. It is highly recommended to apply these same headers to the legacy targets to ensure a consistent and robust security posture across all deployments, unless there is a specific reason for this discrepancy.

[gemini-code-assist]

The value for the X-Content-Type-Options header should be nosniff (all lowercase). While NoSniff might be accepted by some browsers, the specification defines nosniff as the only valid value. Adhering to the standard ensures maximum compatibility.
