Host should deactivate SNMP

MediaNivel 1Automatizadavmware

Descripción

Simple Network Management Protocol (SNMP) facilitates the management of networked devices. Minimize attack surface by disabling non-essential services. The recommended setting is to have the SNMP service stopped unless required and configured securely. The audit runs esxcli system snmp get and requires "Enable: false". When SNMP is required, document the exception and apply 6.4.1. Runs in the ESXi Shell (busybox sh) as root.

Cómo se verifica

Método de auditoría: Comando de shell

shell

out=$(esxcli system snmp get 2>/dev/null) || exit 1
v=$(printf '%s\n' "$out" | awk -F': *' 'tolower($1) ~ /^ *enable$/ {print $2; exit}' | tr 'A-Z' 'a-z' | sed 's/ *$//')
if [ "$v" = false ]; then echo compliant; else echo "SNMP Enable: ${v:-not reported}"; fi

Salida esperada: compliant

Cómo se corrige

Método de corrección: Guía o parche de infraestructura

1. Disable SNMP when not required with: esxcli system snmp set --enable false If SNMP is required, restrict targets/communities, prefer secure SNMP configurations supported by the environment, and limit the ESXi firewall ruleset to authorized management networks.
