# API Security API security is the protection of the integrity of APIs—both owned and in-use API services. APIs are one of the most common ways that microservices and containers communicate including systems and associated applications. As integration and interconnectivity become more important, APIs play a vital part in the security of these microservices. In this section, we will include content that will reflect best security practices including but not limited to the following content: * *API Security Checklist* * *API Security Assessment Tools* * *Summary and Usage of these Tools* * *API Common Vulnerability Blocks* I will try my best to update each of these sections with the latest updates and references, on the best opportunities as possible. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
