Ensure RAM password policy requires at least one lowercase letter

HighLevel 1Automatedalibaba

Description

RAM password policies can be used to ensure password complexity. It is recommended that the password policy require at least one lowercase letter. Enhancing complexity of a password policy increases account resiliency against brute force logon attempts. Reads RequireLowercaseCharacters from aliyun ram GetPasswordPolicy. 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.

How it is checked

Audit method: Shell command

shell

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

Expected output: compliant

How it is fixed

Fix method: Guidance or infrastructure patch

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