Title

MVS data sets for the WebSphere Application Server are not protected in accordance with the proper security requirements. (Cat II impact)

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.

Check Content

a) Refer to the following reports produced by the Data Set and Resource Data Collection: - SENSITVE.RPT(HTTPRPT) - SENSITVE.RPT(WASRPT) b) Ensure the following data set controls are in effect for WAS: ___ The ACP data set rules restrict UPDATE and ALTER access to HTTP product data sets (i.e., SYS1.IMW.AIMW** and SYS1.IMW.SIMW**) is restricted to systems programming personnel. NOTE: If the HTTP server is not used with WAS, this check can be ignored. ___ The ACP data set rules restrict UPDATE and ALTER access to WAS product data sets and associated product data sets are restricted to systems programming personnel.

Fix Text

The IAO 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 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 the HTTP server is not used with WAS, this check can be ignored. 2) UPDATE and ALTER access to WAS product data sets and associated product data sets are restricted to systems programming personnel. SYS*.EJS.V3500108.** (WebSphere 3.5) SYS*.WAS.V401.** (WebSphere 4.0.1) SYS*.OE.** (Java) SYS*.JAVA** (Java) SYS*.DB2.V710107.** (DB2) SYS*.GLD.** (LDAP) SYS1.LE.** (Language Environment)
