Fix Recommendation

Allocate enough storage capacity for at least one week of audit records when audit records are not immediately sent to a central audit record storage facility.

If audit records are stored on a partition made specifically for audit records, resize the partition with sufficient space to contain one week of audit records.

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 TOSS 5 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.

If the system is configured to immediately off-load audit records to an external system, this requirement is not applicable.

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, 10GB of storage space for audit records should be sufficient.

Determine which partition the audit records are being written to using 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 to verify whether it is large enough:

# 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.
