Begin with browsing, account creation, basket changes, checkout, payment confirmation, fulfilment, cancellation and refund. Identify where the platform passes a transaction to another service and where it receives the result. A security assessment focused only on the public storefront can miss privileged order functions or an unsafe assumption about the outcome of a payment request.
Examine prices permissions and state changes
Define authorised tests around discounts, basket totals, order ownership, account roles, refunds and repeated requests. The key question is whether the server enforces the business rule at each step. Use controlled test products and accounts, and agree how transactions will be identified or reversed. Avoid creating real stock, payment or customer-service consequences outside the exercise.
Include customer and administrative access
Review the roles that can read personal data, change an address, view an order, issue a refund or export records. Test users should represent the intended privilege levels and, where applicable, different tenants or stores. State whether administrative interfaces, APIs and mobile clients are included. A customer account test alone does not establish the security of the back office.
Protect production while collecting evidence
Active testing requires explicit written authorisation and an agreed scope. Set transaction limits, monitoring contacts, permitted methods and stop conditions. Coordinate with suppliers if notifications, fraud controls or payment processing could be triggered. A representative test environment can be useful, but document any production differences that affect the conclusions rather than presenting it as identical by assumption.
Turn results into release and remediation decisions
Ask for affected workflows, evidence, business consequences and practical corrections, not only vulnerability labels. Verify that a fix protects related order paths and does not simply suppress one request. Retain the build, scope and retest record. For payment compliance, use the current PCI SSC resources and the applicable assessor's interpretation; a penetration-test report is not itself a PCI compliance certificate.
