Subject Re: oauth token verification in the controller
Date Fri, 21 Jun 2019 17:11:16 GMT
As a budding security engineer, I’ll suggest to emphasize role based
security authorization rather than a permission model. It’s easier to
maintain over time, and it’ll map well to OAuth scopes as well as in JWT
metadata, plus it’ll likely still adapt well to whatever new security
standards are invented.
