Issue security scheme
As explained earlier, the starting point of using issue security is the issue security scheme. It is the responsibility of the JIRA administrator to create and design the security levels so they can be reused as much as possible:
Browse to the JIRA administration console.
Select the Issues tab and then the Issue security schemes option to bring up the Issue Security Schemes page:
Adding an issue security scheme
JIRA does not come with any predefined issue security schemes, so you will have to create your own from scratch. Perform the following steps to create a new issue security scheme:
Browse to the Issue Security Schemes page.
Click on the Add Issue Security Scheme button.
Enter a name and description for the new scheme.
Click on the Add button to create the new issue security scheme.
Since the issue security scheme does not define a set of security levels like the permission scheme, you will need to create your own set of security levels right after you create your scheme...
