How to Secure APIs to Defend Against Emerging Cyber Threats to Digital Web Assets

Application Programming Interfaces, or APIs, enable modern businesses to exchange data and establish connectivity between digital systems. However, increased connectivity needs have spawned more novel security risks as more and more digital assets get deployed on the web. This is why API security has become paramount for any successful business organization, that is exposing its web digital assets on the internet. Common API security risks include things like vulnerability exploitation, where attackers exploit flaws in an API’s construction, or zero-day exploits that exist on the infrastructure where APIs are hosted or most famous DDoS attacks, where APIs are made unavailable, all these risks lead to cyber issues like unintended access, data breaches or data unavailability. There are several best practices to ensure API security, like API OWASP (2023 list) top 10, API rate limiting, DDoS mitigation, payload validation, authentication mechanisms like OAuth, logging and monitoring to ensure accountability and traceability. The purpose of this study is to present an accomplished stepwise solution in the form of an API security framework for organizations that are serious about API security and want to know how and where they can start their journey to secure their digital assets exposed over the web, while still benefiting from them as intended originally.
