The paper that has been published here: https://dl.acm.org/citation.cfm?id=3282283 proposes a consensus algorithm based on distributed voting process in which it claims that it would be possible to detect (and not prevent) MAC address change using Cisco Port Security in a decentralized network.
Do you think it is practicable to detect MAC address change in a decentralized network and without relying on a trusted entity?
Among all techniques proposed to detect MAC spoofing, is there a reliable approach such that we can detect this type of attack strongly?
Some of proposed approaches are as follows:
We hear too much that MAC spoofing is very simple. Does it mean that non of those approaches for detecting MAC spoofing does not work? And in general, does it mean that there is no way to detect MAC spoofing?
Is "fingerprinting a node" can be considered as a solution to identify a node? (https://www.npmjs.com/package/node-fingerprint) or (https://pdfs.semanticscholar.org/d5ef/30919b4f28b82d6fb637e17a5a992f82ecaa.pdf)
P.S.: MAC address change detection using Cisco Port Security is described here: https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst4000/8-2glx/configuration/guide/sec_port.pdf and here: https://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/4_1/nx-os/security/configuration/guide/sec_nx-os-cfg/sec_portsec.pdf
