Join Keith Casey for an in-depth discussion in this video Common Security Considerations, part of Web Security: OAuth and OpenID Connect.
- [Instructor] Now let's talk about how to…properly secure the authorization code flow.…To be honest, this is probably the easiest…to secure by far, which is entirely due…to how this flow works.…There has been one effective attack,…but I'll cover that later.…First, remember that after the user authenticates,…they get an auth code which is server side app…then exchanges for an access token.…That code can only ever be used once.…So while you have to protect it,…it really only matters for a brief window.…
And the user, or any other applications in the browser,…don't ever see the resulting access token.…So that can't leak.…One potential vulnerability,…is that after logging in with your identity provider,…whether it's Google, or Okta, or Facebook,…your user is likely to still have…a web browser session active with them.…If another application can send the user…to the same identity provider without their knowledge…or under a false context,…that could be a problem.…Realistically, those providers may still…request access, or user consent,…
