Building a stellar application that users will love consists of many different decisions, from UI design and color palettes to functionality and feature sets. Writing code that works is a creative process, but it’s only one part of the entire development process. Your app also needs to be secure—not just for the sake of your users, but also for the integrity of your business. Typical security measures when designing your software architecture include:
- Safe and well-tested authentication and authorization schemes
- The ability to control network traffic through firewalls and port monitoring
- Service and resource isolation, so that one server cannot access another
- Securing connections between services via SSL/HTTPS
Together, these practices form a philosophy known as Zero Trust. A Zero Trust architecture is hyper-focused on locking down your application from any and all access. Services are inaccessible to one another by default. Then, over time, and based on need, services are granted access to communicate with one another. In short, services accept outside connections only when it’s necessary. Since the network of your application infrastructure is “closed” by default, this mitigates malicious access and unexpected events.
