Discussion

MVS data sets provide the configuration, operational, and executable properties of the WebSphere Application Server (WAS) environment. Failure to properly protect these data sets may lead to unauthorized access. This exposure could compromise the integrity and availability of system services, applications, and customer data.

Fix

The IAO ISSO will ensure that WebSphere server data sets restrict UPDATE and/or ALTER access to systems programming personnel. Ensure the following data set controls are in effect for WAS: 1) UPDATE WAS: 1) UPDATE and ALTER access to HTTP product data sets (i.e., SYS1.IMW.AIMW** and SYS1.IMW.SIMW**) are restricted to systems programming personnel. NOTE: If personnel. NOTE: If the HTTP server is not used with WAS, this check can be ignored. 2) UPDATE ignored. 2) UPDATE and ALTER access to WAS product data sets and associated product data sets are restricted to systems programming personnel.
