Which of the following attack can be eradicated by converting all non-alphanumeric characters to HTML...

Converting all non-alphanumeric characters to HTML character entities is a common defense against Cross-Site Scripting (XSS) attacks. Here’s how it works:

User Input Sanitization: When user input is received, the system converts characters like <, >, &, ', and " into their corresponding HTML entities (e.g., <, >, &, ', and ").

Preventing Script Execution: By converting these characters, the system prevents potentially malicious scripts from being executed in the browser of anyone viewing the content.

Maintaining Data Integrity: This process allows user-generated content to be displayed without altering the intended message while ensuring the content cannot harm other users or the system.
