Title

All installation-delivered IDMS DBADMIN-level tasks must be properly secured. (Cat II impact)

Discussion

DBA-level tasks that are not secured may allow anyone who signs on to IDMS to use them to access and manipulate various resources within the DBMS. Satisfies: SRG-APP-000033-DB-000084, SRG-APP-000211-DB-000122

Check Content

Examine load module RHDCSRTT by executing CA IDMS utility IDMSSRTD, or by issuing the command "DCMT DISPLAY SRTT" while signed on to the CV and reviewing the output. Note: This requires PTFs SO07995 and SO09476. Validate the following suggested DBA-level tasks are secured in the SRTT (included, for example, in the role of DCADMIN-level security): Note: USER, DEVELOPER, DBADMIN, and DCADMIN are suggested categories only. ADSM ADSOTATU IDD IDDM SSC SSCT If "TASK" is not found as the resource type in any of the entries, this is a finding. If "TASK" is secured internally this is a finding. If "TASK" is secured externally in the SRTT, review the SRTT entries to ensure that the above tasks are secured and review external security manager (ESM) for external class and external name format to make sure the appropriate authorizations have been defined. If they have not, this is a finding.

Fix Text

The SRTT module must be coded to enable task-level security. When using an ESM, this could be done in the following manner: #SECRTT TYPE=ENTRY, X RESTYPE=TASK, X SECBY=EXTERNAL , X EXTNAME=(RESTYPE,RESNAME), X EXTCLS='CA@IDMS' or to give access specifically to one or more tasks (in this case, to ADSM): #SECRTT TYPE=ENTRY, RESTYPE=TASK, X SECBY=OFF, X EXTNAME=(RESTYPE,RESNAME),EXTCLS='CA@IDMS' with an OCCUR statement for each task: #SECRTT TYPE=OCCUR,RESTYPE=TASK, X SECBY=EXTERNAL, X RESNAME='ADSM' Using the above examples, the ESM must be configured to grant access for resource name "TASK.task-name" to security group (or role) DBADMIN, for security class "CA@IDMS", where "task-name" is one of the listed DBA-level tasks. These rules should then be given to the appropriate users. For instance, in Top Secret: TSS PER(user_id) CA@IDMS(TASK.ADSM) In ACF2: $KEY(SGON.the_extname) TYPE(TASK.ADSM) UID(user_id) ALLOW In RACF RDEFINE CA@IDMS TASK.TASK.ASF UACC(NONE) PERMIT TASK.ADSM CLASS(CA@IDMS) ID(user_id) ACCESS(READ) After making the above changes, assemble and link RHDCSRTT to create a new SRTT. To implement the new SRTT, either recycle any CVs that use the SRTT or issue these commands: DCMT VARY NUCLEUS MODULE RHDCSRTT NEW COPY DCMT VARY NUCLEUS RELOAD
