Description: Web application data protection refers to the measures and practices implemented to safeguard sensitive information handled through online platforms. This includes protection against unauthorized access, data loss, and information leaks. Web applications, which are accessible through browsers, often handle personal, financial, and health data, making them attractive targets for cybercriminals. Protection techniques include the use of encryption, robust authentication, input validation, and penetration testing, which help identify vulnerabilities before they can be exploited. Implementing security policies and complying with regulations, such as the General Data Protection Regulation (GDPR) in Europe, are also crucial aspects of data protection. In an environment where security breaches are increasingly common, data protection in web applications has become essential to maintain user trust and ensure information integrity.
