1.321 RHEL-10-700430

Information

RHEL 10 must configure SELinux context type to allow the use of a nondefault faillock tally directory.

GROUP ID: V-281252RULE ID: SV-281252r1166708

Not having the correct SELinux context on the faillock directory may lead to unauthorized access to the directory.

Solution

Configure RHEL 10 to allow the use of a nondefault faillock tally directory while SELinux enforces a targeted policy.

Enable the feature using the following command:

$ sudo authselect enable-feature with-faillock

Create a nondefault faillock tally directory (if it does not already exist) with the following example:

$ sudo mkdir /var/log/faillock

Add/modify the "/etc/security/faillock.conf" file to match the following line:

dir = /var/log/faillock

Update "/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
