## Natural Security

If Natural Security is installed at your site, you have to create the following security definitions in Natural Security:

- Libraries

- User

### Libraries

Library | Description
--- | ---
`SYSSAT` | System Automation Tools application.
`SYSSATU` | System Automation Tools user library.

### User

Define the Natural Security user representing the various servers of the Entire Systems Management products with the user type "person" and the user ID and password identical to the `NSCUSER` and `NSCPSWD` parameters described under Parameter Blocks and Parameters.

In the user security profile, specify Private Library = Yes.

If you define the above libraries as "people-protected", you have to link this user to them.

## External Security System

#### z/OS only

If Entire System Server is installed with an external security system (RACF, CA-ACF2, or CA Top Secret), a user ID identical to the `ESYUSER` parameter (described under Parameter Blocks and Parameters) must be defined in the external security system.

The user must have sufficient authorization to access the spooling system, the console and all data sets used in the online system.
