IBM RACF must protect memory and privileged program dumps in accordance with proper security requirements.

Description
To mitigate the risk of unauthorized access to sensitive information by entities that have been issued certificates by DoD-approved PKIs, all DoD systems (e.g., web servers and web portals) must be properly configured to incorporate access control methods that do not rely solely on the possession of a certificate for access. Successful authentication must not automatically give an entity access to an asset or security boundary. Authorization procedures and controls must be implemented to ensure each authenticated entity also has a validated and current authorization. Authorization is the process of determining whether an entity, once authenticated, is permitted to access a specific asset. Information systems use access control policies and enforcement mechanisms to implement this requirement.

Check Text ( C-25327r514651_chk )
Execute a resource access list for the IEAABD. resources. If the IEAABD. resource and/or generic equivalent is defined with no access and all access logged, this is not a finding. If the IEAABD.DMPAUTH. resource and/or generic equivalent is defined with READ access limited to authorized users, this is not a finding. If the IEAABD.DMPAUTH. resource and/or generic equivalent WRITE or greater access is restricted to only systems personnel and all access is logged, this is not a finding. If the IEAABD.DMPAKEY resource and/or generic equivalent is defined and all access is restricted to systems personnel and that all access is logged, this is not a finding.

Execute a resource access list for the IEAABD. resources.

If the IEAABD. resource and/or generic equivalent is defined with no access and all access logged, this is not a finding.

If the IEAABD.DMPAUTH. resource and/or generic equivalent is defined with READ access limited to authorized users, this is not a finding.

If the IEAABD.DMPAUTH. resource and/or generic equivalent WRITE or greater access is restricted to only systems personnel and all access is logged, this is not a finding.

If the IEAABD.DMPAKEY resource and/or generic equivalent is defined and all access is restricted to systems personnel and that all access is logged, this is not a finding.

Fix Text (F-25315r514652_fix)
Memory and privileged program dump resources are provided via resources in the FACILITY resource class. Configure these resources to the ESM as specified in the following. (Note: The resources and/or resource prefixes identified below are examples of a possible installation. The actual resources and/or resource prefixes are determined when the product is actually installed on a system through the product’s installation guide and can be site specific.) Below is listed the access requirements for memory and privileged program dump resources. Ensure the guidelines for the resource type, resources, and/or generic equivalent are followed. When protecting the facilities for dumps lists via the FACILITY resource class, ensure that the following items are in effect: IEAABD. IEAABD.DMPAUTH. IEAABD.DMPAKEY. The RACF resource rules for the resources specify UACC(NONE) and NOWARNING. Ensure that no access is given to "IEAABD." resource. Example: RDEF FACILITY IEAABD. UACC(NONE) OWNER(owner group) AUDIT(ALL(READ)) IEAABD.DMPAUTH. READ access is limited to authorized users that have a valid job duties requirement for access. WRITE or greater access will be restricted to system programming personnel and access will be logged. Example: RDEF FACILITY IEAABD.DMPAUTH. UACC(NONE) OWNER(owner group) AUDIT(ALL(UPDATE)) PERMIT IEAABD.DMPAUTH. CLASS(FACILITY) ID(authusers) ACCESS(READ) PERMIT IEAABD.DMPAUTH. CLASS(FACILITY) ID(syspsmpl) ACCESS(UPDATE) IEAABD.DMPAKEY. access will be restricted to system programming personnel and access will be logged. Example: RDEF FACILITY IEAABD.DMPAKEY. UACC(NONE) OWNER(owner group) AUDIT(ALL(READ)) PERMIT IEAABD.DMPAKEY. CLASS(FACILITY) ID(syspsmpl) ACCESS(READ)

IEAABD.

The RACF resource rules for the resources specify UACC(NONE) and NOWARNING.

Ensure that no access is given to "IEAABD." resource.

Example:
RDEF FACILITY IEAABD.** UACC(NONE) OWNER(owner group) AUDIT(ALL(READ))

IEAABD.DMPAUTH. READ access is limited to authorized users that have a valid job duties requirement for access. WRITE or greater access will be restricted to system programming personnel and access will be logged.

Example:
RDEF FACILITY IEAABD.DMPAUTH.** UACC(NONE) OWNER(owner group) AUDIT(ALL(UPDATE))

PERMIT IEAABD.DMPAUTH.** CLASS(FACILITY) ID(authusers) ACCESS(READ)
PERMIT IEAABD.DMPAUTH.** CLASS(FACILITY) ID(syspsmpl) ACCESS(UPDATE)

IEAABD.DMPAKEY. access will be restricted to system programming personnel and access will be logged.

Example:
RDEF FACILITY IEAABD.DMPAKEY.** UACC(NONE) OWNER(owner group) AUDIT(ALL(READ))

PERMIT IEAABD.DMPAKEY.** CLASS(FACILITY) ID(syspsmpl) ACCESS(READ)
