CORS configuration Lab

  • Cross origin resource sharing
  • Way of allowing code in one S3 bucket to access or allow to access code in another S3 bucket
  • Allow one resource to access another resource
  • When we link using CORS, it is linked using the endpoint link in static site setup
  • Locate a file from index.html using the endpoint address with the filename on the end
    • Link from bucket loadpage is in
  • Good for organizing website
    • Images in one bucket
    • Javascript in one bucket
    • Use CORS to access them all
  • By default one bucket cannot access another
  • If universal access were allowed, it would be open to attack and information theft
  • CORS allows controlled access between one resource and another
