What is the difference between Issue Security Scheme and Permission Scheme

[arunk]

I am confused with the two schemes Issue Security Scheme and Project Permission Scheme, by the name suggests that former is for Issue and later is for Projects.

Can anyone suggests difference between the two and which one should be used for the different scenarios?

Project Permission Scheme is used for setting level of access to projects.

Issue Security Scheme is more granual. Here you can specify on issue level who has what perimissions on issue.

One use scenario. There is support project, and everyone has access to that project, but just author and wathchers can see issues.

To say short - issue security scheme allows to manually set visibility only of each issues for different users.

For example: admin / user levels. If admin level is set to an issue, users will not see it.
