Need to add security headers and CORS policies

[deviceterra]

As a service provider I need my service to use security headers and CORS policies So that my web site is not vulnerable to CORS attacks

Details and Assumptions

• Flask-Talisman will be used for security headers
• Flask-Cors will be used to establish cross-origin resource sharing (CORS) policies

  Acceptance Criteria

  Given the site is secured When a REST API request is made Then secure headers and a CORS policy should be returned
