# Implicitly (Automatically) Granted Permissions
If a user / role has a write permission to some entity, it is natural to think that the read permission, should also be automatically granted.
Otherwise, How could a user modify an entity if he can't see the record itself in the first place?
StartSharp provides you the ability to auto assign a permission to a user/role, if user has another permission.
It is pretty simple to define such relations between permissions using attributes:
[NestedPermissionKeys]
[DisplayName("Northwind")]
public class PermissionKeys
{
[DisplayName("Customers")]
public class Customer
{
[ImplicitPermission(General), ImplicitPermission(View)]
public const string Delete = "Northwind:Customer:Delete";
[Description("Create/Update"), ImplicitPermission(General), ImplicitPermission(View)]
public const string Modify = "Northwind:Customer:Modify";
public const string View = "Northwind:Customer:View";
}
[Description("[General]")]
public const string General = "Northwind:General";
}
Here we define that, if a user/role has "Northwind:Customer:Delete" or "Northwind:Customer:Modify" permission, they should automatically have "Northwind:General" and "Northwind:Customer:View" permissions.
These relations saves you from having to memorize and check all required permissions manually to grant access to a specific resource in permissions dialog.
It also greatly simplifies access control by letting you use shared permission keys.
