Answer
HTML Entity Encoding converts potentially dangerous characters into safe representations.
HTML Entity Encoding is a technique used to transform characters like '' into '<' and '>', respectively. This prevents malicious scripts from executing in a user's browser. For example, if a user inputs '', encoding will transform it to '<script>alert(1);</script>', rendering it harmless. In Java web applications, libraries like OWASP's Java Encoder can automatically encode user input, significantly reducing the risk of XSS attacks.
