Vulnerability discussion

The NEWPW Control Option specifies the rules that TSS will apply when a user selects a new password.In accordance with DODI 8500.2 for DOD information systems processing sensitive informationand above, and CJCSM 6510.01, the following recommendations concerning passwordrequirements are mandatory and apply equally to both classified and unclassified systems:(1) Passwords are to be eight (8) characters in length.(2) Passwords are to be a mix of alphabetic, numeric, and special characters, including at leastone of each. Special characters include the national characters (i.e., @, #, and $) and othernon-alphabetic and non-numeric characters typically found on a keyboard. NOTE: As of z/OS release 1.9, TSO currently only supports the three National Characters (@ # $).(3) Each character of the password is to be unique, prohibiting the use of repeating characters.(4) Passwords are to contain no consecutive characters (e.g., 12, AB).(5) Passwords are not to include the user’s name, telephone number, userid, or any standarddictionary word.(6) At least one upper case and at least one lower case character..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.

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(TSS0480) b) If the NEWPW Control Option values conform to the following requirements, there is NO FINDING. NEWPW(MIN=8,WARN=10, MINDAYS=1, NR=0, ID, TS, SC, RS, FA, FN, MC, UC, LC) PASSCHAR(@,#,$) Note: These characters will be specified at a minimum. c) If the NEWPW Control Option values do not conform to the above stated requirements, this is a FINDING.

Fix text

Evaluate the impact associated with implementation of the control option. Develop a plan of action to implement the control option setting as specified and proceed with the change. (Support of mixed case passwords can only be set when the security file has been copied by TSSXTEND with the option NEWPWBLOCK) Ensure the NEWPW Control Option values conform to the following requirements: NEWPW(MIN=8,WARN=10, MINDAYS=1, NR=0, ID, TS, SC, RS, FA, FN, MC, UC, LC) PASSCHAR(@,#,$) Note: These characters will be specified at a minimum.
