This whitepaper discusses the evolving role of APIs in cloud-native architectures, particularly in the context of artificial intelligence (AI). It outlines how modern cloud-native applications, built on microservices, are increasingly susceptible to API risks due to the rapid integration of AI features. The document details the inadequacies of traditional web application security measures, such as web application firewalls, in addressing the complexities of distributed architectures. It emphasizes the necessity for continuous monitoring and protection of all API endpoints to mitigate risks associated with unauthorized access and data loss. The whitepaper also categorizes API discovery techniques into three methods: exporting OpenAPI specifications, real-time traffic observation, and log collection, highlighting the strengths and weaknesses of each. Furthermore, it stresses the importance of a comprehensive security strategy that encompasses not just APIs but also the underlying components of applications, advocating for proactive measures to secure the entire development lifecycle from code to cloud.
