Restrict visibility for Issues within a project to "Admin" Group and User

Question

We are looking at recording staff holiday and sickness days within JIRA to keep track of the days, as well as having everything in one program, but don't want everyone to be able to see the number of days another member of staff is entitled too (holiday) or taken as sick.

Is there a way we can restrict the visibility to the User (Assignee) and the Admin group only?

Use issue security levels. Create security levels for the user and admin group only. The user can be captured in user custom field or in the assignee field and that field can be used in the security level.
