Description: Application hardening is the process of securing an application by reducing its attack surface. This involves identifying and mitigating potential risks that could be exploited by attackers. Hardening focuses on implementing security measures that protect both the infrastructure and the application code. Key features include input validation, strong authentication, data encryption, and session management. The relevance of this process lies in the increasing reliance on applications in everyday life and business, where security breaches can lead to financial losses and reputational damage. By hardening applications, the aim is not only to protect sensitive information but also to ensure service continuity and user trust. In a digital environment where threats are becoming increasingly sophisticated, application hardening becomes an essential practice for any organization looking to safeguard its digital assets and maintain the integrity of its operations.
