Security measures such as encryption, tokenization, or data masking are applied to ensure that sensitive information remains secure from unauthorized access or data breaches. Application data security is important for ensuring that personal or financial information is protected in enterprise applications.</p> <h2 id="application-programming-interface-security">Application Programming Interface Security</h2> <p>Application programming interface security refers to the practice of protecting an Application Programming Interface (API) from unauthorized access, data breaches, or misuse. This involves applying security measures such as authentication, encryption, and access control. These measures secure the interactions between systems that communicate through APIs. API security is essential in modern applications where APIs are used to integrate services across cloud environments.</p>
