Final answer:
Header Manipulation is a type of attack where the attacker uses various methods to change values in HTTP headers and falsify access.
Step-by-step explanation:
The correct answer is Header Manipulation. Header Manipulation is a type of attack where the attacker uses various methods to change values in HTTP headers and falsify access. HTTP headers are used to transmit information between a client and a server, and they include information such as the type and length of the content being transferred, the client's user agent, and cookies.
By manipulating the headers, an attacker can modify the content of a website, steal sensitive information, or bypass security measures. For example, an attacker may change the value of the 'Referer' header to trick a website into believing that the request is coming from a different source.
Header Manipulation can be prevented by implementing proper security measures, such as input validation and sanitization, and using secure protocols like HTTPS.
