Ensure that 'Secure transfer required' is set to 'Enabled'

中级别 1自动化alibaba

说明

Enable the data encryption in transit. The secure transfer enhances the security of OSS bucket by only allowing requests to the storage account by a secure connection. For example, when calling REST APIs to access storage accounts, the connection must use ... Every bucket policy must contain a Deny statement conditioned on acs:SecureTransport (requests over plain HTTP are rejected); a bucket without a policy fails. 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.

shell

out=$(aliyun oss ls -s 2>/dev/null) || exit 1
bs=$(printf '%s\n' "$out" | grep -o 'oss://[^[:space:]]*' | sed 's#^oss://##; s#/$##')
bad=0
for b in $bs; do
  pl=$(aliyun oss bucket-policy --method get "oss://$b" 2>&1) || { printf '%s\n' "$pl" | grep -q 'NoSuchBucketPolicy' || exit 1; pl=""; }
  if printf '%s\n' "$pl" | grep -q 'acs:SecureTransport' && printf '%s\n' "$pl" | grep -q '"Deny"'; then :; else echo "HTTP not denied: $b"; bad=1; fi
done
[ "$bad" -eq 0 ] && echo compliant

预期输出: compliant

修复方式

修复方法: 操作指南或基础设施补丁

Add a bucket policy statement {"Effect":"Deny","Action":["oss:*"],"Principal":["*"],"Resource":["acs:oss:*:*:<bucket>","acs:oss:*:*:<bucket>/*"],"Condition":{"Bool":{"acs:SecureTransport":["false"]}}} (aliyun oss bucket-policy --method put oss://<bucket> policy.json).
