1. A computer-implemented method for managing access of wireless nodes to a wireless operational technology (OT) network comprising:
detecting a node from at least one message communication over a wireless OT network;
tracking a node database comprising information corresponding to one or more nodes associated with the wireless OT network, a metadata database comprises information associated with at least one connection of one or more seen nodes of the wireless OT network, and a log database comprising an administrator log associated with at least one of the one or more seen nodes of the wireless OT network;
authenticating node identification information that uniquely identifies the node;
confirming that the node is permissioned to access the wireless OT network by at least validating authentication information associated with the node;
confirming that the node is attempting an authorized action by at least validating authorization information associated with the at least one message communication; and
assigning an access indicator based at least in part on the authenticating of the node identification information, the validating of the authentication information, and the validating of the authorization information.
