# Menu Security

Circulation options can have security at the menu level, submenu level, and/or option level. To assign security, you must first set up user profiles, user groups, and security IDs. Then you can use this option to limit options to one certain security ID.

If a menu, option, or item has no Security ID associated with it, all users have access. If a menu or option has a Security ID, only user groups associated with that Security ID have access to that menu or option. To change security on a protected menu, you must log in with a user ID that has the appropriate Security ID.

Two types of Security IDs may be defined for a menu item:

* **Menu Security ID** – Controls whether the user can access the menu option.
* **Write Security ID** – Controls whether the user can perform write actions, including **Add, Copy, Delete, Default, Enter, and Modify**.

The Write Security ID should be separate from the Menu Security ID to ensure proper separation of read and write access. Write Security IDs follow the standard naming convention and typically end with the letter **“W”** to distinguish them from read-level Security IDs.

If a Security ID is assigned but not linked to a user group, no users will be able to access that menu option.

**Note:** *Do not assign a security ID to a menu option unless the security ID is linked to one or more user groups, and users are assigned to the user groups. If an unlinked security ID is placed on a menu item, no one will be able to access the menu item.*
{% endhint %}

#### To secure a menu item:

1. Select **Menu Security** from the **Security** menu. This option is available in both the Graphical User Interface and the Character User Interface, under **Setup > System > Security > Menu Security**.<br>

3. Press **F1** (or Ctrl-X) when the menu you want to establish security for is highlighted. To access submenus and menu options, press Enter as you normally would, and then highlight the submenu or menu option.
4. Enter the appropriate menu security ID and write security ID. Menu security controls whether the menu option can be used at all. Write security affects the Add, Copy, Delete, Default, Enter, and Modify options.
5. Continue applying security to menu options, or press **F4** to exit to the Setup menu.
