API Security in the Age of Microservices: Protecting Modern Application Architectures
The shift toward microservices architectures has fundamentally transformed application security landscapes. While monolithic applications typically featured well-defined security perimeters, microservices create hundreds or thousands of API endpoints that must be individually secured. This architectural evolution demands a complete rethinking of security strategies, moving from perimeter-based protection to comprehensive API-centric security models. The Microservices Security Challenge Modern applications increasingly consist of dozens of microservices communicating through APIs, often deployed across multiple cloud environments and managed by different teams. This distribution creates an exponentially larger attack surface compared to traditional monolithic applications. ...
