Host must have reliable time synchronization sources

MédiaNível 1Automatizadavmware

Descrição

Ensuring reliable time synchronization is crucial as various functions like cryptography, audit logging, cluster operations, and incident response/forensics are heavily dependent on synchronized time. Utilizing at least four NTP sources is recommended for achieving reliable time synchronization. The audit runs esxcli system ntp get and requires NTP to be enabled with at least one server. Runs in the ESXi Shell (busybox sh) as root.

Como é verificado

Método de auditoria: Comando shell

shell
out=$(esxcli system ntp get 2>/dev/null) || exit 1
en=$(printf '%s\n' "$out" | sed -n 's/^ *Enabled: *//p' | head -n 1)
srv=$(printf '%s\n' "$out" | sed -n 's/^ *Servers\{0,1\}: *//p' | head -n 1)
[ "$en" = true ] && [ -n "$srv" ] && echo compliant || echo "ntp enabled=$en servers=$srv"
Saída esperada
compliant

Como é corrigido

Método de correção: Orientação ou patch de infraestrutura
