| Check Text ( C-46219r2_chk ) |
|---|
| To verify the password reuse setting is compliant, run the following command: $ grep remember /etc/pam.d/system-auth The output should show the following at the end of the line: remember=5 If it does not, this is a finding. |
| Fix Text (F-43608r2_fix) |
|---|
| Do not allow users to reuse recent passwords. This can be accomplished by using the "remember" option for the "pam_unix" PAM module. In the file "/etc/pam.d/system-auth", append "remember=5" to the line which refers to the "pam_unix.so" module, as shown: password sufficient pam_unix.so [existing_options] remember=5 The DoD requirement is five passwords. |
