What process involves changing TCP and/or HTTP headers to manipulate data transfer?

The process that involves changing TCP and/or HTTP headers to manipulate data transfer is known as header manipulation. This technique is often used in various forms of network attacks, such as session hijacking, data injection, or redirecting traffic. By modifying the headers, an attacker can influence how data is routed and interacted with across a network. Header manipulation can lead to unauthorized access or manipulation of transmitted data, making it a significant concern in security practices.

In this context, other options do not accurately describe this type of manipulation. Packet sniffing refers to the practice of monitoring and capturing network packets to analyze traffic, but it does not involve altering any data. Data scrubbing pertains to the process of cleaning data to remove errors or anomalies, focusing on maintaining data integrity rather than manipulating transfer protocols. Network eavesdropping involves intercepting data being transmitted without altering it, focusing instead on passive observation rather than active modification.
