CSRF (Cross-Site Request Forgery) and CORS (Cross-Origin Resource Sharing) are both security mechanisms addressing cross-site requests. CSRF prevents unauthorized actions by ensuring requests originate from the correct site, while CORS allows specific cross-origin requests via preflight checks. The Same-origin policy typically allows cross-site writes (like POSTs) but restricts reads. The introduction of the SameSite cookie attribute has further affected cross-site requests by limiting cookie transmission. Browsers play a crucial role in enforcing these policies, and current adoption rates for security features vary. In summary, both CSRF and CORS are necessary for maintaining web security amid evolving standards.
