Fix Recommendation

Configure Amazon Linux 2023 to provide adequate storage for at least one-week of audit logs when audit records are not immediately sent to a central audit record storage facility.

If the storage partition is not large enough for at least one week of audit logs, then either:

1. Resize the partition to ensure there is enough storage capacity.
2. Create a new partition for the audit logs.

Check Contents

Verify Amazon Linux 2023 allocates audit record storage capacity to store at least one week of audit records when audit records are not immediately sent to a central audit record storage facility.

Note: The partition size needed to capture a week of audit records is based on the activity level of the system and the total storage capacity available. Typically 10.0 GB of storage space for audit records should be sufficient.

Determine which partition the audit records are being written to with the following command:

$ sudo grep log_file /etc/audit/auditd.conf
log_file = /var/log/audit/audit.log

Check the size of the partition that audit records are written to with the following command and verify whether it is sufficiently large:

# df -h /var/log/audit/
/dev/sda2 24G 10.4G 13.6G 43% /var/log/audit

If the audit record partition is not allocated for sufficient storage capacity, this is a finding.
