What changed in z/OS Front End Processor for ACF2 STIG V7R2V7R2 changes

Check text

a) Review site documentation to validate that procedures are in place to protect the FEP service subsystem and diskette drive: - Documents and procedures restricting access to the hardware components of the FEPs. b) If the hardware components of the FEPs are located in secure locations, therethis is NO FINDING. c) If the hardware components of the FEPs are not located in secure locations, this is a FINDINGfinding.

Fix text

Ensure that hardware components of the FEPs are protected as specified below: Physical security is the first level of security control for the FEPs. Install all hardware components of the FEPs in secure locations where they cannot be stolen, damaged, or disturbed. Make sure that FEP hardware is located in a secure area with limited access to authorized personnel.

Discussion

If components of the FEPs are not properly protected they can be stolen, damaged, or disturbed. Without adequate physical security, unauthorized users can access the control panel, the operator console, and the diskette drive of the service subsystem. Therefore, they can interfere with the normal operations of the FEPs. Improper control of FEP components could compromise network operations.

a) Review site documentation to validate that procedures are in place to protect the FEP service subsystem and diskette drive: - Documents and procedures regarding the NCP load and dump processes. b) If a procedure is in place relative to the NCP load and dump processes, there is NO FINDING. c) If no procedure is in place relative to the NCP load and dump processes, this is not a FINDINGfinding.

Fix text

If documented procedures for loading and dumping the FEP NCP (Network Control Program) are not available. Create a procedure document for dumping and loading the FEP and make sure that they are available to the IAOISSO and to authorized personnel responsible to perform these functions.

a) Review site documentation to validate that procedures are in place to protect the FEP service subsystem and diskette drive: - All documents and procedures that apply to FEP operations including network management, FEP initialization, IPL, shutdown, NCP dumping, backup, and recovery. b) If a log is in place to keep track of all hardware upgrades and software changes, there is NO FINDING. c) If no log is in place to keep track of all hardware upgrades and software changes, this is not a FINDINGfinding.

Fix text

The systems programmer will see notice that a a log of all hardware and software upgrades/changes has been created for auditing purposes and problem tracking. All changes and upgrades will be logged.

Title

NCP (Net Work Control Program) Ddata set access authorization does not restricts UPDATE and/or ALLOCATE access to appropriate personnel.

Check text

a) Refer to the following report produced by the Datadataset Set and Resource Data Collection: - SENSITVE.RPT(NCPRPT). ___ The ACP datadataset set rules for NCP datadatasets sets allow inappropriate access. If the following guidance is true, this is not a finding. ___ The ACP datadataset set rules for NCP datadatasets sets does not restrict UPDATEWRITE and/or ALLgreater access to authorized personnel (e.g., systems programming personnel). b) If both of the above are untrue, there is NO FINDING. c) If either of the above is true, this is a FINDING.

Fix text

Identify Names of the following datadatasets sets used for installation and in development/production environments: - NCP system data setsdatasets. - NCP source definition data setsdatasets. - NCP load modules. - NCP host dump data setsdatasets. - NCP utility programs. Have the IAOISSO validate that they are properly protected by the ACP. Andand that only authorized personnel are permitted UPDATEWRITE and/or ALLOCATEgreater access (e.g., z/OS systems programming personnel).

Check text

a) Review site documentation to validate that procedures are in place to protect the FEP service subsystem and diskette drive: - Documents and procedures restricting access to the functions of the service subsystem from the local and/or remote operator consoles (e.g., physical access, password control, key-lock switch of modems, etc.). b) If the following guidance is true, this is not a finding. Verify password controlcontrols isare in place to restrict access to the service subsystem via the operator consoles (local and/or remote), there is NO FINDING. c) IfVerify a key-lock switch is used to protect the modem supporting the remote console of the service subsystem, there is NO FINDING. d) IfVerify nodocuments procedureand existsprocedures exist for any of the above functions of the service subsystem and FEP resources, this is a FINDING.

Fix text

If any of the belowfollowing procedures are not in place, than correct the situation by documenting the missing procedure(s). The systems programmer should validate that Control authorization to use service subsystem console (local or remote) by FEP internal security control through password validation. Restrict access to these passwords to the absolutely minimum number of necessary personnel. Use of vendor default passwords is prohibited. Assign different passwords for the local and remote consoles. Disconnect the local/remote console after three unsuccessful attempts to log on. Passwords used by vendor (COMTEN, IBM, CNT, or AMDAHL) service personnel will be changed after any maintenance is done. All passwords will be changed every 90 days. Restrict permission to change passwords only to authorized personnel. Use a key lock switch on the modem supporting the remote console of the service subsystem to prevent unauthorized access. The key lock switch is only open for scheduled and authorized remote access.
