Ensure RAM password policy temporarily blocks logon after 5 incorrect logon attempts within an hour

AltaNível 1Automatizadaalibaba

Descrição

RAM password policies can temporarily block logon after several incorrect logon attempts within an hour. It is recommended that the password policy is set to temporarily block logon after 5 incorrect logon attempts within an hour. Temporarily blocking logon for incorrect password input increases account resiliency against brute force logon attempts. Reads MaxLoginAttemps from aliyun ram GetPasswordPolicy. MaxLoginAttemps (the API spelling) must be between 1 and 5. 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.

Como é verificado

Método de auditoria: Comando shell

shell

out=$(aliyun ram GetPasswordPolicy 2>/dev/null) || exit 1
v=$(printf '%s\n' "$out" | sed -n 's/.*"MaxLoginAttemps"[[:space:]]*:[[:space:]]*"\{0,1\}\([^",}]*\)"\{0,1\}.*/\1/p' | head -n 1)
[ "$v" -ge 1 ] 2>/dev/null && [ "$v" -le 5 ] && echo compliant

Saída esperada: compliant

Como é corrigido

Método de correção: Orientação ou patch de infraestrutura

aliyun ram SetPasswordPolicy --MaxLoginAttemps 5 (repeat the other current policy parameters, which SetPasswordPolicy resets), or RAM console > Settings > Security Settings > Password Strength Settings.
