• CCI-000135 - Generate audit records containing the organization-defined additional information that is to be included in the audit records.
• CCI-000169 - Provide audit record generation capability for the event types the system is capable of auditing as defined in AU-2 a. on organization-defined information system components.
• CCI-000172 - Generate audit records for the event types defined in AU-2 c that include the audit record content defined in AU-3.

Fix Recommendation

Configure OL 8 to allocate sufficient "audit_backlog_limit" to capture processes that start prior to the audit daemon with the following command:

$ sudo grubby --update-kernel=ALL --args="audit_backlog_limit=8192"

Add or modify the following line in "/etc/default/grub" to ensure the configuration survives kernel updates:

GRUB_CMDLINE_LINUX="audit_backlog_limit=8192"

If audit records are not stored on a partition made specifically for audit records, a new partition with sufficient space will need be to be created.

Check Contents

Verify OL 8 allocates a sufficient "audit_backlog_limit" to capture processes that start prior to the audit daemon with the following commands:

$ sudo grub2-editenv list | grep audit

kernelopts=root=/dev/mapper/ol-root ro crashkernel=auto resume=/dev/mapper/ol-swap rd.lvm.lv=ol/root rd.lvm.lv=ol/swap rhgb quiet fips=1 audit=1 audit_backlog_limit=8192 boot=UUID=8d171156-cd61-421c-ba41-1c021ac29e82

If the "audit_backlog_limit" entry does not equal "8192" or larger, is missing, or the line is commented out, this is a finding.

Verify "audit_backlog_limit" is set to persist in kernel updates:

$ sudo grep audit /etc/default/grub

GRUB_CMDLINE_LINUX="audit_backlog_limit=8192"

If "audit_backlog_limit" is not set to "8192" or larger or is missing or commented out, this is a finding.
