NIST FIPS-validated cryptography must be used to protect passwords in the security database.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-65647	ACF0395	SV-80137r3_rule		High

Description
Use of weak or untested encryption algorithms undermines the purposes of utilizing encryption to protect data. Cryptographic modules must adhere to the higher standards approved by the federal government since this provides assurance they have been tested and validated.

If the "GSO PSWD" record option "PSWDENCT" is set to "XDES" or null, this is a finding.

For CA-ACF2 R16 and above:
If option "NOONEPWALG" is specified, and there is no transition plan with a definite completion date filed with the ISSM, this is a finding.

Fix Text (F-73271r3_fix)
Evaluate the impact associated with implementation of the control option. Develop a plan of action to implement the control option as specified below: Configure the "GSO PSWD" record option "PSWDENCT" to "AES1". For CA-ACF2 Release16 and above: Configure "GSO PSWD" record option "PSWDENCT" to "AES1" or "AES2". Configure the "GSO PSWD" to "ONEPWALG" Note: If you are using VM Database Synchronization you cannot use “ONEPWALG”. VM does not support the AES algorithms. Develop a transition plan with a definite completion date for z/VM; file with the ISSM. If all systems that are sharing the logonid or infostorage databases are not running with the same “PSWDENCT” value you cannot use “ONEPWALG”. Develop a transition plan that contains a definite completion date to migrate all logonid and infostorage databases to one “PSWDENCT” value; file with the ISSM. Consult the CA-ACF2 administration guide for converting to "AES1" or "AES2" and using "ONEPWALG".
