 # API Security
 
 API Security refers to the practices and products that are used to secure application programming interfaces (APIs). In the context of design, it is an essential component that helps ensure that a deployed API achieves its objectives in a safe and secure manner. This includes safeguarding the data, preventing unauthorized access, and protecting the system that hosts the API. API security encompasses the strategies, procedures and technology used to protect APIs from malicious attacks or unauthorized access while guaranteeing optimum performance, availability, and data privacy.
