## Permission Lists

**URL:** `/permissionlists`

Permission lists (PSCLASSDEFN, sometimes called classes) are the lowest-level grantable security object. Every menu, component, page, and function authorization attaches to one.

### What You Can Do

- **View Full Definitions:** See description, last modified information, and general settings.
- **View Authorizations:** See which menus and components the permission list authorizes.
- **View Assigned Roles:** See which roles include this permission list.
- **Sign-on Settings:** View allowed sign-on times and other access constraints.

### When It's Useful

- Auditing what access a particular permission list grants before assigning it.
- Incident response: what could a compromised permission list have touched.
- Finding permission lists that are overly broad (see also the [Full Access Permission Lists report](/docs/reports/security/security-full-access/)).
