How to Prevent CSRF Attacks in Your Applications

Explores three major CSRF attack prevention strategies with practical demonstrations: SameSite cookie attributes that control cross-site cookie transmission, synchronizer token patterns that validate server-generated tokens, and double submit patterns that compare tokens from cookies and forms. Each mitigation addresses different core issues - browsers automatically attaching credentials and servers being unable to distinguish request origins. Includes live code examples and explanations of why attackers cannot forge CSRF tokens due to Same-Origin Policy restrictions.
