ADA-CP 2.9.1 "Ensure IAM password policy prevents password reuse"

[rdegraaf]

Is your feature request related to a problem? Please describe.

The App Defense Alliance Cloud Profile requires a check that AWS remembers and prohibits the use of 24 past passwords (this is the maximum number supported by AWS at this time). This rule will be very similar to "iam-password-policy-reuse-enabled", except that that rule only requires that some number of past passwords are banned, not that it is exactly 24.

Describe the solution you'd like

Implement the check as documented at https://github.com/appdefensealliance/ASA-WG/blob/v1.0/Cloud%20App%20and%20Config%20Profile/Cloud%20App%20and%20Config%20Test%20Guide.md#291-ensure-iam-password-policy-prevents-password-reuse. This can probably be achieved by parameterizing "iam-password-policy-reuse-enabled".
