Ensure that logging is enabled for OSS buckets

中レベル 1自動alibaba

説明

OSS Bucket Access Logging generates a log that contains access records for each request made to your OSS bucket. An access log record contains details about the request, such as the request type, the resources specified in the request worked, and the time and date the request was processed. By enabling OSS bucket logging on target OSS buckets, it is possible to capture all events which may affect objects within an target buckets. aliyun oss logging --method get must return a BucketLoggingStatus with a TargetBucket for every bucket. 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.

監査方法: シェルコマンド

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 $bs; do
  lg=$(aliyun oss logging --method get "oss://$b" 2>/dev/null) || exit 1
  printf '%s\n' "$lg" | grep -q '<TargetBucket>' || { echo "access logging off: $b"; bad=1; }
done
[ "$bad" -eq 0 ] && echo compliant

期待される出力: compliant

修正方法

修正方法: ガイダンスまたは IaC パッチ

aliyun oss logging --method put oss://<bucket> oss://<log-bucket>/<prefix>/ for each listed bucket (or OSS console > bucket > Logging > Enable).
