Using SECLABEL on the logon process

With RACF® installed, you can use security labels to protect messages and data sets. If security labels are used, a SECLABEL is assigned to the user's session. This SECLABEL can be specified in the SECLABEL field in full-screen logon or as an operand on the logon command in line- mode logon. For more information on setting up SECLABELs and security label checking, see z/OS Security Server RACF Security Administrator's Guide.
