Our divide-and-conquer approach for dealing with API security

In order to maintain security across the REST APIs we build, we use a “divide and conquer” approach. We break down request handling into five sequential steps for nearly all endpoints:

1. Input validation
2. Authentication
3. Authorization
4. Execution
5. Output sanitization

To efficiently ensure security, we examine each of these steps individually and leverage existing frameworks like NestJS, Django and Symfony.

The core setup is reviewed annually for each product in our portfolio during our security training sessions to discuss changes and approaches across teams, products, and languages. Additionally, we conduct a quarterly review of each system using a comprehensive security checklist.

Security has become a cornerstone in our product development operations. Always curious to hear about your best practices!
