SV-31711r1_rule Memory and privileged program dumps are not protected in accordance with proper security requirements.

Vulnerability discussion

Access to memory and privileged program dumps running Trusted Control Block (TCB) key 0-7 may hold passwords, encryption keys, or other sensitive data that should not be made available. Failure to properly control access to these facilities could result in unauthorized personnel modifying sensitive z/OS lists. This exposure may threaten the integrity and availability of the operating system environment, and compromise the confidentiality of customer data.

Memory and privileged program dump resources are provided via resources in the FACILITY resource class. The IAO will ensure that IEAABD resources in the FACILITY resource class are defined. When protecting the facilities for dumps lists via the FACILITY resource class, use the following controls: Ensure following FACLITY resource profiles are defined using the following commands: RDEF FACILITY IEAABD.** UACC(NONE) OWNER(owner group) AUDIT(ALL(READ)) RDEF FACILITY IEAABD.DMPAUTH.** UACC(NONE) OWNER(owner group) AUDIT(ALL(UPDATE)) RDEF FACILITY IEAABD.DMPAKEY.** UACC(NONE) OWNER(owner group) AUDIT(ALL(READ)) No access will be given to IEAABD.**. IEAABD.DMPAUTH.** access READ can be made available to all users. IEAABD.DMPAUTH.** access UPDATE access will be restricted to system programming personnel and access will be logged. IEAABD.DMPAKEY.** access will be restricted to system programming personnel and access will be logged. The following commands is an example: PERMIT IEAABD.DMPAUTH.** CLASS(FACILITY) ID(*) ACCESS(READ) PERMIT IEAABD.DMPAUTH.** CLASS(FACILITY) ID(syspaudt) ACCESS(UPDATE) PERMIT IEAABD.DMPAKEY.** CLASS(FACILITY) ID(syspaudt) ACCESS(READ)
