Subject: [PATCH 3/3] Created OVAL for set_password_hashing_algorithm_libuserconf
- Created OVAL
- Updated XCCDF
- Removed accounts_password_hashing_algorithm.xml. The password checks used to be in a singular rule, now
broken into individual components
Testing:
[root at rhel6 checks]# grep crypt_style /etc/libuser.conf
[root at rhel6 checks]# ./testcheck.py set_password_hashing_algorithm_libuserconf.xml
Evaluating with OVAL tempfile : /tmp/accounts_password_hashing_algorithmD_WtnW.xml
Definition oval:scap-security-guide.testing:def:311: false
Evaluation done.
[root at rhel6 checks]# vim /etc/libuser.conf
[root at rhel6 checks]# grep crypt_style /etc/libuser.conf
crypt_style = sha512
[root at rhel6 checks]# ./testcheck.py set_password_hashing_algorithm_libuserconf.xml
Evaluating with OVAL tempfile : /tmp/accounts_password_hashing_algorithm8HlNEH.xml
Definition oval:scap-security-guide.testing:def:311: true
Evaluation done.
