VMware ESXi
TMA-VMWARE-4.8
Host must store one week of audit records
Description
Ensuring a local storage capacity for a week's worth of audit records is imperative, especially when a remote audit record storage facility is used. This provision is critical during anticipated interruptions in record delivery to the remote facility, preventing loss or overwriting of audit records. The audit reads Syslog.global.auditRecord.storageCapacity (MiB) with esxcli and requires the recommended 100 or more; confirm it holds 7 days of records. Runs in the ESXi Shell (busybox sh) as root.
How it is checked
Audit method: Shell command
out=$(esxcli system settings advanced list -o /Syslog/global/auditRecord/storageCapacity 2>/dev/null) || exit 1
v=$(printf '%s\n' "$out" | awk '$1=="Int" && $2=="Value:" {print $3; exit}')
case "$v" in ''|*[!0-9-]*) echo '/Syslog/global/auditRecord/storageCapacity: no integer value'; exit 1 ;; esac
if [ "$v" -ge 100 ]; then echo compliant; else echo "/Syslog/global/auditRecord/storageCapacity = $v (expected 100 or more)"; fi- Expected output
compliant
How it is fixed
Fix method: Guidance or infrastructure patch
Increase the local audit-record storage capacity to store at least 7 days worth of audit logs. execute: esxcli system auditrecords local set --size=<MiB>
