Title

The CA-TSS AUTOERASE Control Option must be set to ALL for all systems. (Cat II impact)

Discussion

Preventing unauthorized information transfers mitigates the risk of information, including encrypted representations of information, produced by the actions of prior users/roles (or the actions of processes acting on behalf of prior users/roles) from being available to any current users/roles (or current processes) that obtain access to shared system resources (e.g., registers, main memory, hard disks) after those resources have been released back to information systems. The control of information in shared resources is also commonly referred to as object reuse and residual information protection. This requirement generally applies to the design of an information technology product, but it can also apply to the configuration of particular information system components that are, or use, such products. This can be verified by acceptance/validation processes in DoD or other government agencies. There may be shared resources with configurable protections (e.g., files in storage) that may be assessed on specific information system components.

Check Content

From the ISPF Command Shell enter: TSS MODIFY STATUS If the AUTOERASE Control Option value is set to (ALL), this is not a finding.

Fix Text

Configure the AUTOERASE control option is set to (ALL) for all systems to erase all residual information on DASD. Evaluate the impact associated with implementation of the control option. Develop a plan of action to set the AUTOERASE control option to (ALL) for all systems and implement.
