Description: Application security refers to the measures taken to enhance the security of an application, protecting it against threats and vulnerabilities that may compromise its integrity, confidentiality, and availability. This includes implementing secure coding practices, conducting security audits, and using tools and technologies that help identify and mitigate risks. Application security is essential in a digital environment where applications are becoming increasingly complex and exposed to cyberattacks. Key features of application security include user authentication, access authorization, data encryption, and protection against common attacks such as SQL injection, cross-site scripting (XSS), and denial of service (DoS). The relevance of application security lies in its ability to protect both users and organizations from financial losses, reputational damage, and data breaches. In a world where applications are fundamental to business operations and social interaction, ensuring their security is a critical priority for developers and organizations alike.
