Ensure that 'Auditing' Retention is 'greater than 6 months'

中等級 1自動化alibaba

說明

Database SQL Audit Retention should be configured to be greater than 90 days. Audit Logs can be used to check for anomalies and give insight into suspected breaches or misuse of information and access. DescribeSQLCollectorRetention ConfigValue (days) must be 180 (6 months) or more for every instance. Iterates every RDS region and instance (DescribeDBInstances). 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.

稽核方法: Shell 指令

shell

regs=$(aliyun rds DescribeRegions 2>/dev/null) || exit 1
regions=$(printf '%s\n' "$regs" | sed -n 's/.*"RegionId"[[:space:]]*:[[:space:]]*"\([^"]*\)".*/\1/p' | sort -u)
[ -n "$regions" ] || exit 1
bad=0
for r in $regions; do
  page=1
  while :; do
    out=$(aliyun rds DescribeDBInstances --RegionId "$r" --PageSize 100 --PageNumber "$page" 2>/dev/null) || exit 1
    ids=$(printf '%s\n' "$out" | sed -n 's/.*"DBInstanceId"[[:space:]]*:[[:space:]]*"\([^"]*\)".*/\1/p' | sort -u)
    [ -n "$ids" ] || break
    for i in $ids; do
      s=$(aliyun rds DescribeSQLCollectorRetention --DBInstanceId "$i" 2>/dev/null) || exit 1
      d=$(printf '%s\n' "$s" | sed -n 's/.*"ConfigValue"[[:space:]]*:[[:space:]]*"\{0,1\}\([0-9]\{1,\}\).*/\1/p' | head -n 1)
      [ "${d:-0}" -ge 180 ] || { echo "SQL audit retention ${d:-unset} days: $r $i"; bad=1; }
    done
    set -- $ids
    [ "$#" -lt 100 ] && break
    page=$((page + 1))
  done
done
[ "$bad" -eq 0 ] && echo compliant

預期輸出: compliant

修補方式

修補方法: 操作指南或基礎設施修補檔

aliyun rds ModifySQLCollectorRetention --DBInstanceId <id> --ConfigValue 180 (or longer), or SQL Explorer > Service Settings > storage duration 6 months or more.
