Abstract
In one embodiment, a method includes receiving, by a security controller, a first security sequence generated by a network controller of a network and a second security sequence generated by a node of the network. The second security sequence is a security configuration of the node when the second security sequence was generated. The method also includes generating, by the security controller, a third security sequence and detecting, by the security controller, a discrepancy between the first security sequence, the second security sequence, and the third security sequence. In response to detecting the discrepancy, the method further includes determining, by the security controller, that the security configuration of the node has been modified.
