Title
The PWEXP Control Option is not set to (60). (Cat II impact)
Discussion
The PWEXP Control Option allows the site to specify a password expiration interval. The system-wide options control the default settings for determining how the ACP will function when handling requests for access to the operating system environment, ACP, and customer data. The ACP provides the ability to set a number of these fields at the subsystem level. If no setting is found, the system-wide defaults will be used. The improper setting of any of these fields, individually or in combination with another, can compromise the security of the processing environment. In addition, failure to establish standardized settings for the ACP control options introduces the possibility of exposure during migration process or contingency plan activation.
Check Content
a) Refer to the following report produced by the TSS Data Collection: - TSSCMDS.RPT(STATUS) Automated Analysis Refer to the following report produced by the TSS Data Collection: - PDI(TSS0550) Note: Current DoD policy has changed requiring that the password change interval be at the most 60 days. Ensure that this is in effect. b) If the PWEXP Control Option value is set to PWEXP(60), there is NO FINDING. c) If the PWEXP Control Option value is NOT set to PWEXP(60), this is a FINDING.
