Description: API security refers to the practices and technologies used to protect APIs from attacks. In a world where applications increasingly rely on communication between services, API security has become a critical component of web application security. This includes implementing robust authentication and authorization, as well as input validation and protection against common attacks such as SQL injection and denial-of-service attacks. API security also encompasses data encryption in transit and at rest, ensuring that sensitive information is not accessible to malicious actors. Additionally, in cloud environments and under a zero-trust model, it is essential that APIs are secure, as they can be an entry point for threats. The integration of DevSecOps practices into the software development lifecycle is also crucial to ensure that API security is considered from the early stages of development. In summary, API security is a vital aspect of protecting the integrity, confidentiality, and availability of data and services in an increasingly interconnected digital environment.
