How We Secure the Order and Payment Flow in eCommerce and On-Demand Apps

Why Order and Payment Security Is Important

An order is not just a purchase made by a customer; it also includes personal data, delivery details, transaction history, items that are bought, and payment details.

If the transaction process is not properly protected at every stage, attackers may take advantage of any weak link by manipulating prices, changing orders, gaining access to customer accounts, causing duplication of transactions, or disrupting payment processing.

Securing User Authentication

The journey of an order typically starts at a user's account. Effective authentication minimizes the possibility of unauthorized persons using accounts to place orders.

Certain security measures such as password policies, secure session protocols, as well as multi-factor authentication, if necessary, are important in lowering risks associated with account usage.

Session expiration settings must also be appropriate, while certain actions may require additional authentication processes depending on the associated risk.

Order protection

The order information should not be trusted just because it comes from the app's interface. Important numbers such as prices, discounts, quantity, costs of shipping, and availability of the product should be verified on the server-side.

For instance, a request transforming product prices should not lead to an order being accepted at a price lower than the legitimate one.

Authorization policies are also critical. Users must be able to see or change only those orders which they are supposed to access.

Securing Payment Processing

Payment information must be treated carefully and responsibly. Applications are advised to avoid storing payment data or to use reliable payment service providers and secure payment methods.

In order to transmit payment data, secure communication protocols should be used.

Validation is also required for payment callbacks and transaction status notifications. The application should not consider an order paid if the request on the customer side states that the payment has been successfully completed.

Avoiding Duplicate Payments

Technical errors sometimes occur, and during instabilities in the connection, customers could click the payment button several times.

Using techniques to avoid multiple requests helps prevent charging several times for the same transaction.

In addition to that, transaction statuses should include clear definitions of its state, for example, pending, successful, failed, returned, etc.

Monitoring and Logging

The process of security doesn't come to an end once the order has been executed. Logging and monitoring can highlight anomalies like repeated failed payments, suspicious account behavior, unexpected changes to orders, and unusual API requests.

It is extremely important to secure the logs from unauthorized changes and avoid unnecessary storage of sensitive payment data.

Our Security Procedures

At Dev Technosys, we embed security measures throughout the entire process of placing and processing the order while developing our e-Commerce & on-demand apps. Depending on the specific case, the security measures may involve secure authentication, server-side validation, authorization controls, encrypted communication, payment integration, transaction integrity, API security, and monitoring.

Testing is also vital. Security testing can reveal such possible issues as price manipulation, authorization failures, replay requests, session vulnerabilities, and unexpected transactions before the software goes live.

Security Throughout the Process

In addition to just safeguarding payment information, a secure payment experience also requires secure authentication, order processing systems, APIs, databases, third-party integrations, and other business logic to achieve a secure transaction.

By taking all of these elements into consideration and actually testing them out throughout the process, teams can create eCommerce and on-demand applications that can provide a secure and consistent experience.
