APIs, essential for communication and data exchange between applications, are particularly vulnerable to cyber threats like injection attacks, which involve inserting malicious code into an application to execute unauthorized actions. These attacks are projected to significantly increase, posing substantial financial risks and leading to more data breaches than average security incidents. The threats exploit weaknesses in API endpoint security, often due to rushed development, inexperienced developers, and poor coding practices. Injection attacks can take various forms, including SQL, NoSQL, and command injections, targeting different parts of the data processing workflow. To combat these threats, a multi-faceted security strategy is necessary, incorporating both preventative and defensive measures such as input validation, parameterized queries, and the use of API gateways. API gateways play a crucial role in scrutinizing requests and blocking malicious ones before they reach backend systems. Solutions like the Injection Protection Plugin in Kong Gateway Enterprise 3.9 are designed to identify and block suspicious patterns, offering both default and customizable protections to secure APIs against a range of injection attacks.
