When an attacker successfully inserts an intermediary software or program between two communicating hosts, it is known as man-in-the-middle attack.
The correct answer is C. Man-in-the-middle attack.
A man-in-the-middle (MitM) attack is a type of cyber attack where an attacker intercepts and alters communication between two parties who believe they are communicating directly with each other. This is accomplished by the attacker placing themselves in the middle of the communication path between the two parties, making it appear as though they are communicating directly with each other.
To perform a MitM attack, the attacker must have access to the communication channel. This can be done through various methods, including physical access to network devices or by exploiting vulnerabilities in software or network protocols.
Once the attacker has access to the communication channel, they can intercept messages and potentially alter them to their advantage. For example, the attacker could modify a message to change the destination address, redirecting it to a malicious server they control.
MitM attacks are a serious threat because they can compromise the confidentiality, integrity, and availability of the communication. The attacker can potentially steal sensitive information or inject malicious code into the communication stream.
Denial-of-service (DoS) attacks involve overwhelming a target system with traffic to prevent legitimate users from accessing it. DoS attacks do not involve interception or modification of communication.
Dictionary attacks involve attempting to guess a password by trying a list of commonly used passwords or dictionary words. Password guessing attacks involve systematically trying different password combinations until the correct one is found. These attacks do not involve interception or modification of communication.
