Fix Recommendation

Configure AlmaLinux OS 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) using the following command:

$ mkdir /var/log/faillock

Update the /etc/selinux/targeted/contexts/files/file_contexts.local file with the "faillog_t" context type for the nondefault faillock tally directory using the following command:

$ semanage fcontext -a -t faillog_t "/var/log/faillock(/.*)?"

Update the context type of the nondefault faillock directory and files within using the following command:

$ restorecon -RFv /var/log/faillock

Check Contents

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 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

system_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.
