CAPTCHA (Completely Automatic Public Turing test to tell Computers and Humans Apart) is used to differentiate humans from bots. It prevents automated attacks like DoS, DDoS, and spam by requiring users to identify text or images before submitting a form.
To ensure its effectiveness, CAPTCHA validation should always be performed on the server side, not just the client side. This prevents attackers from bypassing it by disabling JavaScript or tampering with client-side code, ensuring only genuine human interactions are processed.
It protects pre-login forms (like sign-up or feedback) from bots that flood servers with fake requests, preventing DoS or buffer overflow attacks and keeping the website stable.
