Ensure that 'Auditing' is set to 'On' for applicable database instances

MediumLevel 2Automatedalibaba

Description

Enable SQL auditing on all RDS except SQL Server 2012/2016/2017 and MariaDB TX. The Alibaba Cloud allows MySQL instance to be created as a service. Enabling auditing at the server level ensures that all existing and newly created databases on the MySQL instance are audited. DescribeSQLCollectorPolicy must report SQLCollectorStatus Enable (SQL Explorer / audit) 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.

How it is checked

Audit method: Shell command

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 DescribeSQLCollectorPolicy --DBInstanceId "$i" 2>/dev/null) || exit 1
      printf '%s\n' "$s" | grep -Eq '"SQLCollectorStatus"[[:space:]]*:[[:space:]]*"Enable"' || { echo "SQL audit off: $r $i"; bad=1; }
    done
    set -- $ids
    [ "$#" -lt 100 ] && break
    page=$((page + 1))
  done
done
[ "$bad" -eq 0 ] && echo compliant

Expected output: compliant

How it is fixed

Fix method: Guidance or infrastructure patch

aliyun rds ModifySQLCollectorPolicy --DBInstanceId <id> --SQLCollectorStatus Enable (RDS console > SQL Explorer > Enable).
