API Security in Microservice Architecture: Methods to Prevent Injections

The paper analyzes security threats related to APIs in microservice architecture and proposes methods of
their neutralization. The main attention is paid to the problem of injection, which is one of the most
critical threats to the stability and security of microservice-based systems. Different types of techniques
for preventing tampering, including SQL, command-line, and HTML, are discussed and strategies for
preventing them are proposed, including input sanitization, use of parameterized queries, and privilege
delimitation. Tools and technologies that can be used to improve API security, including access control
systems and the use of secure programming patterns, are also discussed. The analysis results show that
the integrated application of the proposed techniques can significantly reduce the risk of successful
attacks
