(MitM) attack occurs where communication between two network devices is intercepted by an attacker. The attacker can then impersonate both communicating devices‚ relaying information between the two‚ such that the communicating network devices will not know that their communication has been compromised. This allows the attacker to read potentially confidential data only intended for the two devices communicating‚ or even change information as they see fit. The challenge for an attacker is finding

It can apply to wired and wireless mode of transmission of data and connectivity between networked components. There are several network layouts/topologies among which are (a) Bus topology. (b) Star topology. (c) Ring topology and last but not the least (d) mesh/hybrid topology. Their names are very descriptive of how they look like.
