Description: JSON security refers to the methods and practices implemented to protect data structures in JavaScript Object Notation (JSON) format from malicious attacks. JSON is a lightweight data interchange format widely used in web applications and APIs due to its simplicity and ease of use. However, its popularity also makes it an attractive target for attackers. JSON security involves data validation and sanitization, the use of schemas to define the expected structure of data, and the implementation of appropriate access controls. Additionally, aspects such as authentication and authorization must be considered to ensure that only authorized users and systems can access and manipulate the data. Adopting a Zero Trust security approach is essential, as this model assumes that threats can exist both inside and outside the network, and therefore, every access request must be independently verified regardless of its origin. In this context, JSON security becomes a critical component for protecting the integrity and confidentiality of data in various applications and systems that utilize JSON.
