Why in JIRA "Security Schema"?

Question

JIRA

Tell me, is there any point in using the "Security Scheme" if you can configure everything in the "Permissions Scheme"?

Answer 1

The security scheme simply limits the "visibility" of the hare. Access rights - the ability to do something with this application. For example, the developer role can only comment on the application, and the qa role can transfer from status to status. With the help of a security scheme, it is possible to limit whether the applicant is in principle visible, for example, to qa or to the developer.
To be honest, in 99% of cases this garbage does not apply. This is for Business processes related to personnel, for example, or internal requests. When the application by default will have the security scheme "Only the Head", and the rest "everyone else".
