Description: Insecure APIs are Application Programming Interfaces that have vulnerabilities that can be exploited by attackers. These interfaces allow communication between different applications and systems, facilitating the exchange of data and functionalities. However, when security measures are not properly implemented, APIs can become an entry point for cyberattacks. The main characteristics of insecure APIs include a lack of proper authentication and authorization, exposure of sensitive data, and absence of input validation. The relevance of this topic has grown in the digital age, where organizations increasingly rely on APIs to integrate services and applications. The security of these interfaces is crucial, as a compromised API can lead to data breaches, information manipulation, and other types of attacks that can severely affect the integrity and reputation of an organization. Therefore, it is essential to conduct vulnerability analysis on APIs to identify and mitigate potential risks, thus ensuring the protection of the systems and the information they handle.
