Ensure Flow Logs are enabled for every VPC

СредњаНиво 2Аутоматскаibmcloud

Опис

Flow logs capture network traffic metadata for monitoring and investigations. In the targeted region every VPC must be referenced by at least one flow log collector (VPC- or subnet/instance-level). Read-only ibmcloud CLI calls using the current CLI session and targeted region (ibmcloud login, or IBMCLOUD_API_KEY); JSON output is parsed with grep/sed/awk. A missing CLI, plugin or session fails the check.

Како се проверава

Метод провере: Команда љуске

shell

vpcs=$(ibmcloud is vpcs --output json 2>/dev/null) || exit 1
fl=$(ibmcloud is flow-logs --output json 2>/dev/null) || exit 1
bad=0
for v in $(printf '%s\n' "$vpcs" | awk '{ o = gsub(/\{/, "{"); c = gsub(/\}/, "}") } d == 1 && /"id"[[:space:]]*:/ { s = $0; sub(/^[^:]*:[[:space:]]*"/, "", s); sub(/".*/, "", s); print s } { d += o - c }'); do
  printf '%s\n' "$fl" | grep -qF "\"$v\"" || { echo "no flow log: $v"; bad=1; }
done
[ "$bad" -eq 0 ] && echo compliant

Очекивани излаз: compliant

Како се исправља

Метод исправке: Смерница или закрпа инфраструктуре

ibmcloud is flow-log-create --bucket <cos-bucket> --target <vpc-id> --name <name> --active true for each listed VPC (requires a COS service-to-service authorisation).
