Check Text (C-271836r1092637_chk)
Note: If the system does not have SELinux enabled and enforcing a targeted policy, or if the pam_faillock module is not configured for use, this requirement is Not Applicable.
Verify that OL 9 configures the SELinux context type to allow the use of a nondefault faillock tally directory.
Verify the location of the nondefault tally directory for the pam_faillock module with the following command:
$ grep 'dir =' /etc/security/faillock.conf
dir = /var/log/faillock
Check the security context type of the nondefault tally directory with the following command:
$ ls -Zd /var/log/faillock
unconfined_u:object_r:faillog_t:s0 /var/log/faillock
If the security context type of the nondefault tally directory is not "faillog_t", this is a finding.
Fix Text (F-75793r1092219_fix)
Configure OL 9 to allow the use of a nondefault faillock tally directory while SELinux enforces a targeted policy.
Create a nondefault faillock tally directory (if it does not already exist) with the following example:
$ sudo mkdir /var/log/faillock
Update the /etc/selinux/targeted/contexts/files/file_contexts.local with "faillog_t" context type for the nondefault faillock tally directory with the following command:
$ sudo semanage fcontext -a -t faillog_t "/var/log/faillock(/.*)?"
Update the context type of the nondefault faillock directory/subdirectories and files with the following command:
$ sudo restorecon -R -v /var/log/faillock
