TMA-ALIBABA-1.4

Ensure that multi-factor authentication is enabled for all RAM users that have a console password

AltaNivel 1Automatizadaalibaba

Descripción

Multi-Factor Authentication (MFA) adds an extra layer of protection on top of a username and password. With MFA enabled, when a user logs on to Alibaba Cloud, they will be prompted for their user name and password followed by an authentication code from their virtual MFA device. MFA requires users to verify their identities by entering two authentication factors. When MFA is enabled, an attacker faces at least two different authentication mechanisms. Every RAM user with a login profile (console access) must have an MFA device (GetUserMFAInfo). Read-only aliyun CLI calls; credentials and default region come from the CLI's normal profile (aliyun configure, ~/.aliyun/config.json or ALIBABA_CLOUD_* environment variables). JSON output is parsed with sed/awk. A missing CLI or credential fails the check.

Cómo se verifica

Método de auditoría: Comando de shell

shell
out=$(aliyun ram ListUsers --MaxItems 1000 2>/dev/null) || exit 1
users=$(printf '%s\n' "$out" | sed -n 's/.*"UserName"[[:space:]]*:[[:space:]]*"\([^"]*\)".*/\1/p')
bad=0
for u in $users; do
  if err=$(aliyun ram GetLoginProfile --UserName "$u" 2>&1); then
    if ! err=$(aliyun ram GetUserMFAInfo --UserName "$u" 2>&1); then
      printf '%s\n' "$err" | grep -q EntityNotExist || exit 1
      echo "no MFA: $u"; bad=1
    fi
  else
    printf '%s\n' "$err" | grep -q EntityNotExist || exit 1
  fi
done
[ "$bad" -eq 0 ] && echo compliant
Salida esperada
compliant

Cómo se corrige

Método de corrección: Guía o parche de infraestructura

Have each listed user bind a virtual MFA device (RAM console > Identities > Users > Authentication > Enable MFA) and require it: aliyun ram UpdateLoginProfile --UserName <u> --MFABindRequired true.
