Ensure that RDS instance requires all incoming connections to use SSL

VisokaNivo 1Automatskaalibaba

Opis

It is recommended to enforce all incoming connections to SQL database instance to use SSL. SQL database connections if successfully trapped (MITM); can reveal sensitive data like credentials, database queries, query outputs etc. DescribeDBInstanceSSL must report SSLEnabled Yes/on 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.

Kako se proverava

Metod provere: Komanda ljuske

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 DescribeDBInstanceSSL --DBInstanceId "$i" 2>/dev/null) || exit 1
      printf '%s\n' "$s" | grep -Eiq '"SSLEnabled"[[:space:]]*:[[:space:]]*"?(yes|on|1|true)"?' || { echo "SSL off: $r $i"; bad=1; }
    done
    set -- $ids
    [ "$#" -lt 100 ] && break
    page=$((page + 1))
  done
done
[ "$bad" -eq 0 ] && echo compliant

Očekivani izlaz: compliant

Kako se ispravlja

Metod ispravke: Smernica ili zakrpa infrastrukture

aliyun rds ModifyDBInstanceSSL --DBInstanceId <id> --ConnectionString <endpoint> --SSLEnabled 1 (RDS console > Data Security > SSL Encryption), and require TLS in the database engine.
