Effective Strategies to Protect Web Applications from CSRF Attacks

This paper discusses effective strategies for protecting web applications from CSRF (Cross-Site Request Forgery) attacks. The mechanisms of action of CSRF attacks, their potential threats and methods of their implementation are analyzed. The main focus is on security methods, including the use of CSRF tokens, checking the Origin and Referer headers, as well as configuring the SameSite attribute for cookies. Recommendations on the use of two-factor authentication and the implementation of middleware for token management are provided. The principles of the Same Origin Policy and the CORS (Cross-Origin Resource Sharing) mechanism, which provide additional levels of protection, are also considered. The work highlights the need for an integrated approach and continuous security monitoring, since using one method does not guarantee complete protection.
